Title: Raider Clutch master cylinder issue
Post by: Raiderftw on Jun 09, 2021, 08:36:22 pm
OK so had a leak at the pivot point of the clutch lever. Ordered the replacement part from yamaha. Local mechanic took the bike in for a clutch master cylinder rebuild. Told me that yamaha gave me a rebuild kit for the brake master cylinder on accident but he can use the same o rings case they look the same. Got the bike back the next day and clutch lever felt great.

2 days later took it for a ride... Heres what I noticed

A- Saw a good amount of a clear fluid on the top cap of the clutch master cylinder cover. Level was still full in sight glass.
B- Lever pulls fine but when I let it go it doesn't go all the way back on its own, maybe 1/4 inch i can push out with my fingers.
C- Now having issues shifting from first into 2nd gear only. Sometimes works fine sometimes takes 2-3 tries to get it into gear. Never did this before.

Called the mechanic and he's gonna look it over for free. Said worst case scenario I may need a new master cylinder which is almost $500

In your opinion would a leaking hydraulic clutch cause the shifting issues?  Bike has 30k miles on it and never did it before. This is my first bike with a hydraulic clutch...

It's very possible he put the cups on backwards or the cups may not be exactly correct for the bore of the clutch master cylinder.  Hopefully he'll find the problem.

If you have leaking fluid, make sure you clean it off everything ASAP. Brake fluid can be a wonderful paint remover.

Yeah - if the master isn't actuating the slave, you will have issues.  Get it fixed properly.  My slave cylinder failed and shot me/bike into an intersection.  Thank god no one was coming.

Just a follow up. My mechanic rebuilt the clutch master cylinder for free. No more issues. So moral of the story is to make sure when u order a rebuild kit for your clutch, you don't get a brake rebuild kit instead. Because both packages from yamaha just say master cylinder rebuild. Apparently the o rings have just enough difference in size that they leak.
