sticking clutch plates on A 2006 YZ450

11 posts in this topic

I was talking to my friend about my issue I'm having with my clutch. It worked fine when I got the bike back in december and now it doesn't disengage the clutch with i pull it in and no matter how I adjust it it still stalls. Do I need a new clutch kit or is there something I can do to get it working again? I drained the oil to do a HD stator and when I filled it back up I put amsoil in so low quality oil isn't an issue.

Could be you have groves worn on the clutch basket fingers. You can lightly file them till they're smooth. The clutch hub can also have grooves worn into it. They are a little harder to smooth out.

Most likely your basket and hub are grooved, like stated you can file them I'd they arnt terrible. If they are really bad you should replace with a new unit or preferably a billet basket for longer life.

Before ordering any parts id take the clutch apart and measure your frictions and steels and inspect the basket and hub for grooving.

They don't fail that often, but check your clutch springs, too. The manual shows what to look for in the specs section or under Clutch.

Ok thanks guys I'll do a good inspection and hopefully I don't need to replace anymore parts right now.

I got the bike running yesterday and took the clutch apart to see what it was. The basket and plates looked good so I put it back together and still sticking. I pushed it down the hill with the motor running so when I shifted to 1st it wouldn't stall and it worked, It freed the clutch up and works fine now.

I guess you just need to put the ride words into google, I googled wet clutch sticking and it looks like it's a common issue with wet clutches, mainly after sitting in the cold but some guys say it happens even sitting for a few days. It looks like I just need to rock it back and forth before staring it to try to free up the plates cause guys are saying if I just pull the clutch in and drop in, I can damage the output shaft splines.

Baloney.  It's not going to be "good for them", but the jolt they get from bouncing the clutch loose is not comparable to running full throttle through a series of potholes.

I'm not sure I follow what you're saying, what about running full throttle through a series of pot holes?

The thrust impact transmitted to any component of the transmission when the wheel looses and suddenly regains traction under full power, or land a jump under power, is exponentially greater than what happens when you step it into gear at a high idle, even if you completely forgot to pull the clutch in.

oh ok, I got it now. I guess that makes sense and it's not putting much stress just dropping it into first.
