Weegie

It would appear so Phil I looked on the other head nothing. Then checked it with a thin piece of bicycle cable and it appears closed but still deeper than I'd like and the cable bottoming is no guarantee that it still isn't a leak path Any ideas on sealing, you think JB Weld would be sufficient or is a head removal and strip in my future? John

I'm not holding out much hope here as very few mount a pressure gauge onto their bikes or even test it. However if anybody out there has information from their motorcycle I'd be interested. This all started with a HiCam I have and was related to both overheating and oil pressure, anybody who frequents Wild Goose should be well aware of the problem as I've posted about it until everybody there is sick to the back teeth with it.......................so I came here . I can't be bothered going into the details about the overheating, but I thought the overheating and low pressure were linked, now I'm starting to think that the low pressure isn't a problem at all and for close to 2 years I've been chasing a ghost. Recently I've gained a little more information, but its left me with a whole raft of questions that leave me baffled and confused. Lucky Phil came onto WG and started to assist, nothing definitve came of that, except I gained a lot more knowledge about these engines and I'm grateful for all his insight and time that he invested. Starting from what I'm used to 2 valve engines 4 bar (58 psi) relief pressure, cold oil idle 65 psi or a little above (I assume the relief valve gets overwhelmed and pressure builds a bit over the valve setpoint) Hot running above 3k approx high 50s or low 60s psi Hot idle 15-10 psi usually Hi Cam 5 bar (72 psi) relief pressure (larger oil pump), cold idle 50-54 psi Cold to 3k, approx 70 psi (that test was done on a stationary engine and turning the pump with a drill, from experience it doesn't matter much if the engine is rotating or not) No hot data to speak of right now, as the bike was only run once and was overheating so I haven't got a data point where the temperature reached an equilibrium So I start to chase the missing pressure, the relief valve is set higher and I'm at least 10 lower perhaps 15 psi. I'll let Kevin_T chime in if he wants to give his side but he stated on page 5 of Phil's HiCam build thread he never seen the pressure higher that 53psi on a Centauro (another C kitted HiCam) Then fortuitously a buddy tests his Hi Cam engine, all of these HiCams are C kitted, just for completeness Cold idle 52-53psi Blip on cold to 3k approx 70psi (actual running engine) Let it get warm (but not stabilised just for a few minutes till the heads are warm, perhaps 10 minutes idling) 48psi One more thing, When I removed the rocker carriers (which also locate the cam followers) and left the head oil feed holes to the rocker exposed then cranked the bike the oil pressure on the gauge dropped from 50psi to 32, cold oil. These feeds do not appear to me to be that large, so the 18psi drop was a surprise. The green arrows are the exposed feeds I wonder is the pressure I'm seeing system wide or is the pressure switch tapping point I'm measuring the pressure from badly placed, it never was after all meant to really represent true system pressure. The take for me is there probably nothing wrong with the pressure on my engine but I'm left wondering why the readings are so low. The V11 went back from the Hi Cam's 21mm lobe pump to a 16mm but drives at a higher Crank/pump ratio and I hope to get some data on that soon Anybody who had data they could add would be of interest to me and possibly to others .

Could not agree more with both Lucky Phil and Pete Roper's posts Although Joe and me often correspond (got a mail this morning from him) I have no skin in the game whatsoever. Steel is the only way to go for material, Pete's seen countless wrecked engines with alloy gears and I've had a few acquaintences over the years send me photos of their personal horror stories. I installed gears as I preferred the simplicity of design (although designing a gear set is a far from simple process), it was something less to think about, no lash, no adjuster to check etc: Standard setup works very well there is no denying that, so in the end you pays your money and takes your choice

I have Joe's gears in a Sporti 1100, LM 1000 engine and in a HiCam. The HiCam engine currently has issues totally unrelated to the gearset at the moment. I know of a few others who have them installed too, and never heard anything but positive things said. Apart from the cost, Joe's gears are more expensive than a lot want to pay. IMHO Joe's gears are the only viable alternative to chain sets, and after emailing him a lot over the years I can personally vouch for him Anyway this might also help if you want to enquire https://woodburymotomedia.com/moto-guzzi-timing-gears-by-joe-caruso/ John

Even though it's not revving hard I think I've got a flavour of it, sounds really really good. Can imagine that given some throttle it would be real howl, thanks for that. Of course this has now really got me thinking

Beautiful bike & of course the pipes just look amazing the way they curve and swoop Got any video? It would be nice to hear how it sounds

Why Thank You Kelly that is so kind of you to go to the effort of posting up and thanking me for the gearbox article. The gearbox isn't difficult, the hardest parts are getting these dammed nuts off the back and front after that its no harder than a Meccano set (if you're old enough to remember Meccano) I'm no mechanic just a bodger, guy's like Lucky Phil and Chuckee are the real artisans and both of them have been more than generous with their time and perhaps other members I still need to get to know For electrical issues Kiwi Roy is my main man and I see he's here too. At the moment I'm looking at a low pressure issue on the Oz's HiCam engine that's being going on forever. Now I have a plan of action, based on Phil's advice. In 2 or 3 weeks time after having completed these checks I've got to make a decision on should I tear it to pieces myself or ship the engine down to a trusted engine builder and just let him get on with it. John

Lol I'm starting to feel at home already. Phil & docc, just stop it, I know about these exhuasts and they are stunning, always fancied them. Now you've got me wondering, don't know if Magni's still up and trading right now. Perhaps I'll drop him a mail Hi Tim, well the 1100 might just have stopped leaking since you seen it. Chuckee, no real story, posted as Old Jock on WG as it was a brew in my local, a pint of which would stun a horse. Weegie is a shortening of Glaswegian used by residents of that other city to the east of us (capital of Scotland) and isn't a term of endearment Phil your correct of course on the Australia (or Oz as I irrevantly know it as) I think Ted Stolarski was a dealer and racing them in the 80s or 90s and when Magni brought out the bike it was named the Australia in Ted's honour. 2 batches built First in 93, I think 75-80 built used a tubular frame similar to Sfida 1000s and Forcelle Italia forks. The engine was the standard Daytona Hi Cam Second in 98, around 50 built, used the beam frame like Guzzi's Daytona and Sporti (and the Sfida 1100 and Sfida 1000 4V) and Paioli forks. The engine was a C kitted Hi Cam identical to the Daytona RS They planned a far larger production run but Guzzi couldn't provide them with the HiCams hence the low numbers John

Thankyou so much to everybody, to docc for providing the link, to Phil (whose already educating me big time on the HiCam engines) and to everybody else kind enough to pop in and welcome me Looking forward to getting to know you all So the Red Headed Step Child that is proving to be a bit of a challenge, when she's fully clothed which she hasn't been for some time The other bike shown there is a Sfida 1100 just a Sporti given the Magni treatment. Probably not his most attractive design, but eye catching nonetheless......possibly a love hate design. I've had people tell me it's an abomination and others that it's good looking (in a strange way), reminds me of some girls I went out with. I've added a few farkles to the 1100, which probably hasn't done much to improve it John

So after being on WildGoose forever I thought I'd come on here, I post as Old Jock on WG, but went for a change of moniker Don't own a V11 so what the hell am I doing here? Well I've got a bike with a HiCam engine in it that's giving me endless trouble and may be getting another, glutton for punishement I was attracted by the legend that is Lucky Phil, I see some other of the "usual suspects" too and some of the technical topics on here are first class As I couldn't find an introduction section I just thought I'd post up here and introduce myself.
