So, I have to ask: are all the 2012 model year CARC bikes a clutch spring time bomb?
No, it seems there was a small batch of rotten plates, most if not all of them went in Stelvios. By no means are all 2012's time bombs. Mine still had its original clutch when I swapped in the 1400 motor and it was fine. Sure it had the 'Stelvio Groan' but nothing ever went wrong with it and it had done 110,000Km plus.The thing to worry about more is whether the bike was built before the change to roller tappets!Pete
Its a work in progress. Other builders of larger capacity 8V's are having problems too. The issue is almost certainly a matter of crankcase volume. Once my Stelvio is mapped correctly we'll find if the 1400 bottom end architecture helps address the problem. My own feeling is that taking the engine out that much is really pushing the friendship but I have no conclusive evidence yet.Pete
1400's are prone to it too, although less so if thrashed mercilessly from new.
SMDL, There is a way to not have to drop the transmission or abuse a good dog. Just ride the second bike and forget about the troublesome one. You did say that it was reliable
Are you pulling apart a Stelvio?
I would replace the breather hoses that connect to the rear cam cap while everything is apart, they go way up front to under steering stem.
Just curious and asking within prejudice. What is the major or even mine differences between this clutch/pressure plate and most all the other major brands that this issue is mostly non existent?
My understanding is that this was related to a bad batch of clutches, and that the newer design doesn't have this problem.
Looks like I may have clutch issues....clutch was not disengaging fully, on a ride today..then made a weird sort of ping noise and now works normally...I'm thinking a spring has dislodged. I am about 100km form home so will be a slow gentle ride then investigate further. Anyone have experience on the symptoms of a spring falling out?
My understanding is that this was related to a bad batch of clutches, and that the newer design doesn't have this problem. That's all I know.Cheers,Shaun
Necro Thread!Is there a known production range of potentially affected clutches? Either by VIN or engine number? Most are referred to as 2012, or even early 2012, but some reportedly failed on "2013" bikes. I have seen no mention of production dates. When did MG switch to the 1400 clutches?I know this is only affecting a handful of bikes, so far. But the prospect of needing to complete this replacement approaches horrifying. I am hesitant to even consider a 2012 - 2013 bike with the original clutch. Considering the current values of these bikes (I've seen a few sub $5000 examples) vs the $1000US price of the clutch set and what, $2000 labor? This would basically be a write off. A smart person would probably buy only the upgraded bikes. If only I knew when that was? 2014? 2015?
I just yanked a bad one out of a late 14 model Stelvio , the 13 year is total bull, they used up all their stock first.This one locked the motor, 2 springs came loose.
