  1. Ten years ago I would of been all over it like a rash. Now? Nope! I have Griso. Griso will see me out.

    EICMA 2021

    Can anybody really think of anything more embarrassing than wishing to have a 'Card' that has to be shown to indicate you are a member of a business sponsored advertising program called a 'Clan'? It is so monstrously cringeworthy it deserves a triple facepalm in a darkened room! Do these people have no dignity to loose? Just looking at the awful 'Presentations' used in early 'Clan' promotions made me feel soiled and my gorge rise. How dreadful can it possibly get?
  3. Jason, if you need a kit I can probably supply cheaper than most and will be able to make sure you get the correct one. If you're interested PM me and I'll send you my email address. Oh, and I suggest you read this. https://www.grisoghetto.com/t5879-the-definitive-guide-to-rollerisation
  4. Not seemingly with the ones I know of. The Stelvio's suspension is also longer travel and 'Plusher' than that used on the supposedly purely 'Road' models but it was Stelvios that had the breakages. Yes, it is thought that the stress raiser was from one of the hose clip holes. I've never been close enough to one that it's happened to to know, but it makes perfect sense. It's also one of the reasons I think fitting a sidecar to a CARC bike is a really silly idea but people do that as well.
  5. As with so many things it seems to have hit Stelvios, and as I said, I know of four. In fact I sent a bloke in South Africa a swingarm when his bust because he was getting stonewalled by the importer. I know of two in Oz. Both of which were denied warranty because they had been 'Abused', (I have it on good authority that they weren't, in any way shape or form.) and the last one was in Canada and resulted in serious injury and it went to court. I do not know the outcome.
  6. Yup, but I know of four cases of this issue, all from the same model run, in a period of twelve years. From memory it was one run of 2012 Stelvios but don't quote me on that. The factory, naturally, denied it. I keep an eye on this shit because I'm interested. I think the BMW issue was considerably more common. Nobody is perfect but the Bavarians are much worse than Guzzi.
  7. Yeah you got truly stiffed. I got the only available Conti Road Attacks in the country, two sets, for just over a grand a couple of weeks ago. They're on the shelf waiting for me when I need them. I just don't get why some people feel the need to stiff others. It's a very short term strategy.
  8. Admit it! You like it because you got charged $400 for it by a shill!
  9. All the 'Broad Sump' components are identical physically between the assorted bikes that use the system. As noted, the difference is simply the colour. Foto is offering a 'Try Before You Buy' deal on a part that hasn't been available for years ex factory. I'd grab it with both hands and be amazed that you have been kissed on the arse by a golden fairy!
  10. The governing factors are going to be issues such as valve float and rod integrity rather than timing when talking about the cam drive.
  11. It makes bleeding the clutch on CARC bikes a dream.
  12. Why would the fuel boil? It’s nowhere near any heat source. A blocked tank vent causing pressurisation problems I can see but not boiling….
  13. Cliff's ECU is actually a top quality and fully tunable unit. It's not some lashed together add on bit of junk and you know how generally scathing I am about most aftermarket stuff.
  14. Did those fork measurements come through Phil?
  15. Forced induction on spark ignited engines is a first class ticket to misery on steroids!
  16. I think that just proves my point. My mate Dave, (RIP.) had a Harris swingarm on his MkVI LeMans that floated the bevelbox. It was an absolute frontbottom of a thing!
  17. Chris, the dash reading is simply ambient temp, it's sensor lives up by the dash and doesn't have any feed into the ecu. The ambient air temp sensor is in the airbox and the engine temperature sensor is in the back of the RH head.
  18. Phil, believe me. Mark knows exactly what he's doing and knows the W5AM inside out.
  19. Cut-in on mine is at 2,700. I haven't noticed any problems but that could simply be me. Mark's maps generally have the fuel edited out to that point unless specifically requested otherwise. I don't think he has many requests for its reinstatement.
  20. What exactly happens on the over-run? Is it backfiring? And what pipe are you running? If aftermarket, does it have a dB killer installed? They will all tend to backfire a bit on the over-run. The stock mufffler tends to mask it pretty well and the sound of it becomes both more noticeable and more prevalent the more 'Open' the pipe. It is one of the peculiarities of the Webber system that the ecu will keep delivering the idle fuel, that which is delivered at 4.8* throttle angle in the case of a Stelvio, at all engine speeds when the throttle is closed. Now while the crank is turning at idle speed the fuel delivered is just sufficient to keep the afr correct-ish so the engine will run and the mixture will ignite every second revolution as it should. The problem occurs when the motor is spinning harder and therefore pumping harder. As the engine slows down the rapidly pumping pistons will greatly increase the manifold depression on the engine side of the butterflies so more aiir gets pushed past them. Now the ecu is delivering just enough fuel for the engine to idle but with this situation the mixture is incombustible lean. It won't ignite in the cylinder every revolution, it's simply too lean to do so and it gets pumped through the motor and expelled unburnt into the exhaust. Over a period of cycles of the engine harmonics and residual mixture left behind as end gas in the cylinder will periodically reach the point where the mixture will ignite and when this happens as soon as the hot, still burning, exhaust gasses are expelled into the exhaust they will ignite the previously expelled unburnt mixture causing the backfire. Harmonics play a big part in this and you will probably notice that the backfiring will occur at certain precise points as the engine is slowing down. That's why. Most fuel systems nowadays get around this problem very easily. They simply stop all fuel delivery on a closed throttle until the engine slows down to a certain point. Phil has previously explained that it is very easy to do the same thing with the Webber system. You just yank the map out of the ecu, open it with Tunerpro and then reduce all the figures in the first two columns of the map to zeroes above the point where you want fuel delivery to recommence. Most people who do this opt for 2,500-2,700 rpm. It has the added advantages of slightly increasing engine braking, reducing fuel use as well as killing exhaust popping stone dead! If there is no fuel being delivered then there is nothing to burn. Nothing to burn and there is no backfiring! Simples! Also if you are an easily entertained peasant like me it means that on hills like the one descending into Queanbeyan from Bungendore you can go down the hill in a high gear using engine braking to slow you down and playa game where you judge your slowing down so when the fuel cuts back in and causes the bike to give a little lurch as it does so it coincides with passing the 60kph speed limit sign on the edge of town! Yeah. I'm a bear of very little brain....
  21. First check the paint on the throttlestop screw is intact. Then check the ball joints are unmolested. Then see what the TPS reading is but don't reset it especially if the throttlestop screw has been moved. Report back.
  22. I don't doubt it but getting the TPS out of the RH TB is pretty much impossible without buggering it on the big throttlebodies and you'd also have to remove the stepper if you wanted to plunge-bath the whole lot. I'm too lazy for that.
  23. For cleaning the TB's I just take them off. Yeah, getting the airbox in and out is a bit of a pain but as long as you don't over fill the sump you really don't have to do it very often. When Michael was swapping my gearbox on the Griso for a Sport 1200 one a few weeks ago we pulled the TB's off and they were pretty grubby after 40,000 or so Km and needed doing but this had been exacerbated by me over-filling the big Green Pig for ages. I've got one of those oil temperature gauge dipsticks, (Initially because I was interested in oil temperatures but now I just keep it because I'm a wanker!) and I'd forgotten I'd marked it with a 'Full' mark to be used on the sidestand. I'd been using it with the bike upright which adds about 1/2 a litre more oil that it needs and it was simply pumping it out into the airbox. I've given myself a slap on the wrist and suitably severe talking to, (Made worse by Michael rolling his eyes and not saying anything!) but generally, as long as you don't over fill it I would think every 30,000 km should be fine. Really it's a matter of looking and judging for yourself. If they look grubby? It's probably time! As for cleaning the stepper? I simply get the bike warm and pull the stepper hose off the front left of the airbox, turn on the stepper activation with Guzzidiag and spray carby cleaner down the hose while goosing the throttle! Repeat unti the stepper works properly! Once the TB's are on the bench it's a pretty simple matter to scrub them clean with carby cleaner and a soft brush and gentle cloth. It's actually quite impressive how much nicer the bike will run after this is done and it's given a proper tune-up.
