  1. You guys must be waaaaay to law abiding, something like that in the UK would either get stolen or spray painted over in a matter of hours There's a very good reason all the cameras are mounted on posts or are difficult to get at, even then it still doesn't stop some of them getting vandilised from time to time. Average speed cameras are probably the way most places will go where practical, unfortunately very effective unless the monitered detection length is known and if they have a few up it becomes just about impossible. Situation will only get worse as the prices of cameras comes down
  2. Ok @Lucky Phil that's handy to know, may try that or at least make sure my stock clearances are on the loose rather than the tigher side. I'd have thought that you'd want to transfer heat to the head from the valve as much as possible, the head surely is running a LOT cooler and the mass of the head will result in a higher thermal inertia, not to mention the oil in it and the airflow over it. Mind if it's hot in the first place the exhaust valves are going to have an even more difficult time................Sodium core valves anybody? Phil's bound to know all about them Your cams are Centauro and mine are RS, slightly different but I don't know if it's significant. Of course Dynotech could just be wanting sell cams From what I can gather from the description Pete it appears that Guzzi must have had issues with the exhaust valves over the years, to go to the trouble of a dedicated pump Looked at the MGS-01 and V11 parts out of interest. They both have similar looking oil coolers but different part numbers, but that's all I got. The MGS also has what I think was a transducer (perhaps going to warning light?) across the cooler but later replaced with a relief if I've got it correct. It also sports lines directly to the heads on the cooler outlet. That's not presesnt on any of the other HiCams........................mmmmmm, wonder if that was a first attempt to feed colder oil directly to the heads. After some messing around it does look like mounting the cooler won't be as bad as I thought, just need to make up some straps and I reckon I can mount it with 4 P clips to the frame rails. One question for the more knowledgeable, most cooler installation feed & return lines to the top of the cooler. I've seen some installations on other bikes where they feed & return to the bottom. I'm guessing the top is desirable to allow gas/air to escape through the lines, rather than potential trapping of air inside the cooler reducing efficiency. Unsure if I'll be able to install with the lines to the top, it will be more difficult for sure due to all the other stuff crammed above the cooler John
  3. Ok Pete I'll gratefully accept your more than generous off. If the Setrab fails to deliver the Stelvio cooler would certainly be an option worth trying, PM me with the shipping costs. You've lived and breathed these engines all your working life Pete, so any advice you care to throw my way I take very seriously so I'll go away for a "think" All I can say from my (very limited) experience, with the RS is that the HiCams seem to behave a bit differently to the 2V engines that I'm familiar with. That's limited to to bikes up to the turn of the last century. I read that Beetle's torque monster engine was stupidly overcooled (paraphrasing his word) but know absolutely nothing about the more recent engines and the technology involved. About the only consensus I can get on the HiCams from outside sources (forums etc:) is the heads run hot. Some seem to be able to tune them to stupid powers and get them to run fine yet mine "appears" to overheat stock. My old stock Daytona which I sold never seemed to have any issues, yet the stage C kit only contributes around 5bhp.........................there just has to be something staring me in the face and I'll be dammed if I can see it Oh and the point of the quote on the cam was that Dynotech Germany offer a cam with a steeper ramp profile that prevents the valve being lifted for long periods and improves the head temperatures. John
  4. Hi Phil Hummmm, that's interesting, depending on where in Germany he is, he'll probably encounter higher ambients in the Summer than we get in Scotland. So you're telling me that Karsten actually junked the cooler and made a loop pipe. Although not to the same degree I do know of another Australia owner, whose bike has the standard Daytona engine but upraded to Stage C. His bike seems to run low oil temperatures too, it has a 10 row Mocal cooler installed and even with a Vee piece across the front of the fairng (from a Ducati to stop muck getting thrown into the engine) his temps are on the low side. Running a 23-25C ambient, he told me 20 minutes to achieve 80C, normal running 90C and extended traffic light stops up to 105C, These temperatures are with the Vee piece in place. The vee piece has raised his oil temps by 5-10C. I wonder if mapping has anything to do with this. Joe Caruso also sent me a screenshot he'd taken from the Daytona Facebook page which originated from Jens Hofmann The Daytona Rs Vam is the Kit cam from Daytona 1000 like you know. This cam has a very long ramp. The result is that the head gets very hot because the valves are 60 ° not presses is the valveseat and cant give their heat away. There seems to more to this as some seem to report good to low temps and others on the high side, but as I've no clue why all I can do is see if the new cooler improves anything The cooler arrived this morning and looks a bit smaller than the standard which doesn't fill me with confidence, but I'll press on anyway as presently I can't see another path to pursue John
  5. This is a long sad saga on how one person can be so stupid and how you should always listen to Chuck. I purchased a low mileage Australia 98 from Japan a few years back, HiCam engine and running gear identical to a Daytona RS As Winter was coming on apart from idling the bike to check as much as I could that all was in order the bike did no running. I purchased a Caruso pump and gear set to remove the "grenade with the pin pulled" oil pump and to a lesser degree the suspect OEM Aluminuim gears for the service shaft and oil pump drive, the OEM crank gear is steel. I also installed an oil pressure gauge and a dipstick temperature gauge. There were other things done along the way but they're not relevant. Come the next summer I took it out for a ride, the first thing I noticed was the low oil pressure on cold oil at idle, around 50-52 psi. The traffic getting out of town was particularly bad, with road works, diversions, queues and snarled up traffic. Just as I got by the worst of this I seen the oil pressure light come in. Went into panic mode looked at the pressure gauge somewhere between 5-10psi. Pulled off into a convenient car park adjacent to me, killed the engine and freewheeled to a stop. Checking the temperature it was in excess of 120C. Waited for well over an hour perhaps longer until the temperature dropped to around 60C and rode home via a backroad a cab driver told me about. On the ride home I was still dropping oil pressure and rising temperature. As I recall it was about 25psi when I got home, I cannot remember the temperature. Although a backroad with less traffic I was still limited to 30mph, so at no point did I really get the chance to get up speed and some real airflow around the engine. With the low pressure at idle I was convinced that the overheating and low pressure were linked and as the pressure was low from the outset thought I'd start there. The 2V bikes I'm used to will run cold idle circa 60-65+ psi. Cutting to the chase after pulling the bike apart several times, installing several pressure gauges, the OEM pump plus another Caruso pump, running multiple experiments swapping over all sorts of parts between my Sport engine and HiCam, dimensioning several bearings and journals (but not all) and about to strip it again. Lucky Phil stepped in and started to make suggestions on checks. These came to nothing BUT give me a far greater understanding of the engine architecture and I'm very grateful to him. Without his intervention I'd probably have had the engine apart (or in a skip). I also got a friend with another HiCam engined bike to install a gauge onto his and he saw 50psi cold idle. This took another interesting turn when Phil fired his blueprinted HiCam, as he had installed a stronger relief valve spring and obtained 105psi. This told me that the pump has more than enough capacity to support engine oil requirements when escaping via the normal engine bleeds & bearings BUT with the relief closed. When Phil then installed the standard spring, his pressure dropped to 50psi cold idle, so the culprit had to be the relief partially lifting early, that Chuck had told me about so long ago. I'm hazarding an "informed" guess here, but think with the large oil feed to the heads, not present on the 2V bikes to anything like the same degree, it doesn't take much lift from the relief for the system pressure to start bleeding down. Joe Caruso has been brilliant and invaluable during all this, providing me with a lot of pump data and insight. One of the facts made me go "WIDE EYED" was the HiCam oil flow from the pump, was the highest of all the bikes of this vintage. The pump gears are longer (all the pump gear diameters are the same) and spinning faster than the V11 or the MGS-01. So that's where I am now, I'm going to install a Setrab 13 row cooler, which involves shifting some components around & will hopefully improve the heat rejection avialable from the cooler. At the moment there is 15/50 full synth in the bike and if I still encounter rising temps the next move will be to step up to a 10/60 to see if the higher viscosity at elevated temperature will sustain the oil pressure. This was also Lucky Phil's suggestion and Paul Minnaert's on a Facebook Daytona page. I've still a ways to go though to complete the cooler install & here we're still under lockdown, so sometime, hopefully sooner rather than later, I'll be able to take it out and see what happens Just thought it might bring a little insight to those of you lucky enough to posess one of these wonderful machines. I'll update this as and when but it will be slow John
  6. Hi Pete very generous of you as always and thank you so much, I may take you up on it later.......................I just took a look on the Bay of Fleas and have you seen what people are asking for some of these parts? You're sitting on a gold mine!!! Right now I need to get the rest of the crap shoehorned into the upper front of the bike to see exactly what's going to fit. Two of the reasons for considering the Setrab/Mocal route apart from the fact I know they will probably fit are 1) I know another Australia owner who runs a 10 row Mocal with dash 8 piping and reports oil temps on the cool side if anything. That's an earlier bike but has been upgraded to a stage C tune. So it's not a broad sump and has a modified Finkentey Klaumann sump and spacer, for the take off to fit a cooler. It can't be a deep sump though as there's no room on the Australia to install one because of the fairing. I have no idea if it makes any difference or not 2)The Setrab/Mocals have a lot of published data on their cooler performance and the upshot is the bigger the better, within reason. Greater heat rejection and lower pressure loss, if you've got a stat to control it. I don't think Guzzi's coolers have as many rows Vs their physical size and I'm desperately trying to maximize heat rejection through the cooler. I need to start a seperate thread on this and the oil pressure behaviour to continually stop Lucky Phil's thread going Off Topic.
  7. Thanks for the update Phil You make me look an utter dullard (not that hard mind). Amazing work and breadth of knowledge you're posting up here. Why are you running a 15M out of interest could you not get your hands on a 16M? Are you planning to do anything regarding the relief valve spring in the future or just let sleeping dogs lie? Tell me about access to the oil pressure take off, it's a compete Bee-atch After doing the cam timing check on mine and trying to install a larger oil cooler where the OEM lived on the HiCam I had to admit defeat. A Setrab or Mocal could be installed but the piping was impossible. I'm now in interation #2 and have relocated the external fuel pump and when the pieces arrive fit the filter (tubing and 2 large P clips). That should free up space between the Alternator cover and front subframe brace. In there I can squeeze a 13 Row Setrab and have sufficient room twixt cooler and sump ports to actually pipe it. I'll post up a separate thread when its done. Pretty simple stuff but it was driving me nuts. I'll also let you know when the Will Creedon chip arrives Please keep this updated it's a gold mine for anybody brave/masochistic enough to venture into the altered reality that is the world of HiCams (Although I still think they are the sexiest lumps Guzzi ever made). John
  8. If you do half the job you did on the V700 Dave it'll easily be like the lower picture. Lucky bike finding such a good home. Calis are amazing machines, I thought they would be Harley like in the their handling until I was out on a group ride years back. I was on a Daytona and the guy in front on a Cali, I had difficulty keeping up with it, could not believe how much they can be thrown around and handle so well. Great bikes, I love these earlier versions
  9. Stunning Dave Wish I was half as talented to do something like that
  10. Thanks Phil All these contributions are very much appreciated. I reckon a 10/60 it is for the HiCam and I'll just continue with my 15/50 in the 2V bikes for now. In Scotland max ambients tend to be mid 20s and when I'm out in the Summer lows probably mid teens. John
  11. I hope on here that oil threads are a bit calmer than on WG where everybody goes NUTS with illl informed opinions I had overheating on a HiCam which resulted in low oil pressure and I'm guessing, no more than that, that a combination of these engines running very hot in traffic and possibly the relief valve behaviour, it starts to leak around 50psi and yes most of them seem to do that, is contributing to the dropping pressure. At the time bike overheated, I was running a Motul 15/50 full synthetic and just wondered opinions regarding upping viscosity to a 20/50 or even 20/60 weight oil. That won't stop the overheating but might help allleviate the plummeting oil pressure. AFAIK the recommended weight is 20/50. Do some of the later bikes not run a 10/60? Really I'd rather run a lighter rather than a heavier viscosity but when my oil sump temp reached 120C the oil pressure had dropped to under 10psi although that was a circa 2k RPM At the moment it's just a thought, I'll probably try a 20/50 first. Anectodally I've also seen some people posting that changing oil vendors can even have a marked difference
  12. Rolls Royce Piston Aero Engines - a designer remembers by AA Rubbra, liking your taste in reading Phil..........a lot. A great read, as are many in that series if you love engines

    @gstallons I'm retired now, used to work with Gas Turbines, first in maintenance then latterly doing performance and tuning. Predominently industrial units but some aero derivatives and some steam turbines as well. I was a mechanical engineer but always had an interest in electrical and instrumentation, which was handy for setting up to measure performance runs. I was nothing special and certainly don't posess much talent, to this day I shudder when I think of some of the stupid s**t I did over the years. As far as the job travelled all over doing it, it was a mixture of hands on and engineering evaluation, really enjoyed it and some fantastic times. Guys on here like @Lucky Phil, @Kiwi_Roy , the inimitable @pete roper and no doubt many more, are way more talented in there respective fields than I could ever be. The wiring on the bike was my first ever attempt at a rewire, it's Ok but not in the same league as others, especially some of the guys who worked on aircraft. Second attempt on a mate's V7 racer, that he put back to road use, was a little better. Heartly agree with @knumbnutz, using an M-Unit makes the job a lot easier, if costly. Wiring isn't hard, especially on bike's of that vintage. Break down the circuits, make a diagram of how you're going to do it. Use the diagram to evaluate current/load and size the wire to suit. Once you've did all that you get hands on and route the cables, bundling them into groups. Lastly make the terminations. For detail, the box between the M-Unit and the fuse box housed a resistor (now relocated and replaced with a metal clad unit) in place of the generator warning light. The big silver box houses the electronics for the Sasche electronic igntion and a terminal strip where I had to common up connections. I'd have did it a bit different now but it all works.............so far. Here's short video of an early start after the refurb if anybody's remotely interested, its changed a little since then, but not so much. https://www.youtube.com/watch?v=-G5zCu5UkEA&feature=youtu.be John
  15. Pete when he's referring to Differential he might mean Bevel box?
