I read this on another forum as a solution to clutch slip. Does it sound right? I can't even find the chrome clip he's on about..... Solution: At the bottom of the clutch master cylinder reservoir you will see a small chrome clip. This is a splatter guard to keep fluid from splattering when you activate your lever with the cover off. Carefully remove it using a toothpick so as not to damage it and you will see what appears to be a partially drilled hole. At the bottom of this is a tiny hole the size of a very small pin which gets clogged very easily especially if the fluid hasn't been changed for a while. This tiny approx. 1/128 inch hole allows just enough fluid to escape back into the reservoir to allow your clutch to fully engage. Your fluid expands when warm and that is why the problem is worse when the bike is hot. This hole is forward of the rubber plunger on the clutch piston so you can unclog it with a small pin without worrying about puncturing the rubber plunger inside. Be careful not to enlarge this hole. After doing this you will find that the clutch not only fully engages but the lever begins to engage almost immediately just like a brand new bike and it is easier to find neutral too. NOTE: It has nothing to do with your choice of oil and it is NOT your clutch plates being worn or soaked with oil. EASY solution and I hope you pass this on as this applies to all Hondas with a hydraulic clutch but unfortunately none of the manuals I've read addresses this issue. cheers Simon
I just realized what he was saying. You have to take the top MC cover off. Then look inside for the small chrome clip. There's a hole under it. I don't know if that would cause the problem of clutch slip if that hole was plugged. I've never had that happen to me. I change those fluids every other year and don't have any gunk in mine. I can see the point behind it though.
Yes that is correct. It happens all the time. You read many posts on all the forums titled... "Having trouble bleeding my brakes." That hole is important to be clear,and it can get clogged. Brake or clutch master. It is like putting your thumb over a straw full of fluid. The fluid will just stay in the straw and not move. BUT...IT will not cause the clutch to slip. It just makes the master not able to let fluid into the wheel cylinder of the brake. Or on a clutch the clutch will not have enough pressure to push the rod. Remember the clutch IS fully engaged when there is no pressure. It is disengaged when there IS pressure.
