It's the tappet said that fail not the cams. How do the tappet said look?Pete
It sounds as if you made the right decision ,an once of prevention is worth a pound of weed. Or something like that. Did you perform the surgery yourself? Are you still running the factory fuel map? How was the wear on the cam followers? Just curios. dave
Could you supply a link to the ADV rider thread?Thanks
Had you noticed a change in running behavior prior to the conversion? Particularly idle behavior? Or a sudden increase in valve gaps?
Bill just sent me the link. Thanks guys.Yes, classic failure of the DLC coating. They were just starting to go. When you look at the damage with an electron microscope you can clearly see how the coating de-laminates and then gets pounded to a slurry by the cam flanks. That stuff is very hard, (Hence its name, diamond like carbon.) and if the damage isn't caught early it does a lot of damage as it circulates in the oil.Pete
Of course, after reading that the rollers then require the owner to research aftermarket maps to regain previous performance (hit a wall at 6500rpm on a Griso .... you have to be kidding!?) ..... well, what the hell, maybe I'll simply act like I've never read any of the posts on this site, and run the little begger until it blows. At least she winds to 8000rpm with flat tappets with the greatest of ease.
No, no, no. The rollers will work fine with the factory map. It's only those running open-loop non-stock maps that need to get updated.
That was originally my understanding too but the source of that pearl of wisdom has long been discredited in my book so my answer is I'm really not sure.My guess would be though that it will trim pretty much all the way through but because the narrow band sensor takes a few seconds to trim it won't often get the chance. In lower gears with a wide open throttle it will bounce off the limiter before it has time to trim and in higher gears you'll be going 'Fuque me drunkque' fast which can be problematic!Pete
OK, but if that is so how come the Grs8V-03 map works with the roller set up? I would of expected that it would have a lousy effect in the same area that the open loop maps are which is high throttle, high RPM?Pete
