Hello Spyder Lovers,

Haven't been in here in quite a while to add to this thread. The shop has been busy and there have been several projects tying up the lift. Finally got to the Spyder and I have much to share about the clutch chatter issue. Didn't want to post anything until I got enough test miles on it to say it's fixed.

I have specs and real test data to share if you guys are interested but at this point the clutch doesn't chatter.........at all. There is no RPM flare at any engine speed.

Still putting some pictures and test data together.

More to come.

Did you have to put a new clutch assembly in to get a cure? I've always had a problem with the 'It's Normal, they all do it' answer. As I know they don't all do it. Even if it is 'Normal', doesn't make it right. I think it all started when BRP revamped the engagement curve on the SE5's. This because so many people were lugging and shifting at too low RPM. Which created clutch slippage issues over time. It's easier to modify the machine than to educate the rider. So, BRP made the clutch engage and go to full lock-up sooner. Even so, it should still provide for a smooth engagement. A chattering clutch is never a good thing. I just don't see it as 'OK'.

Hey Baja,

Nice to see you're still hanging out in here. I wanted to change the clutch but couldn't get one. So I did the next best thing, clutch disks were a little scorched but not bad.
The stack measured .060 below the lower service limit. I had obtained a shim kit (BRP had that part) . So I shimmed the pack .082 and it fixed the stupid thing.
Three dealerships physically looked at this clutch and no one caught this. Good help has gone from hard to impossible to find. Oh well, you want something done right?

I think this is possibly the fix for any of these bikes. This is a complicated clutch system and adjustment is critical. You just need to know how and a few special tools.

Wow! Sorry I did not see this one sooner! Great information and glad you shared. 'Better late than never', they say.

RobertJ thank you for coming back and letting us know what you found and how you solved it. There are still a lot of VTwins running around out there and discussions about them are fewer and fewer. My 2012 has 75,000+ miles on it and while the clutch works fine for now it will wear soon enough. Helpful to know about the shim kit.

Lucas 10-40 blend for wet clutches got rid of mine on a 15 se5 with 45 k on it.
