WR450 05 Starter Noise / Occasonally will start
Posted August 23, 2007 - 02:58 AM
Did a search of the above problem and it sounds like it might be the starter clutch? But I want some more advice.
A few weeks back my start button switch stuck and the starter motor could be heard running after the engine had started.
Replaced the start switch after a few more rides but now when I try to start always getting a weird whirling type noise and sometimes it will start with the button sometimes not. Battery is fully charged.
Always starts first time on the kicker but again the whirlly noise is present just as the engine fires up.
Have I f****d the starter by running around with a dodgy switch?
If so whats the best course of action?

the funny thing about mine is that sometimes it makes noise and will slip som much as to not turn the engine over, and other times it won't give me any problems at all. Today I rode it and not once did it make the noise. But the last time I rode it last week it made a bunch of noise.
You've got it! It not predictable at all, but a pain in the arse in the mountains when reverting to the kick start constantly.
Ordered a new starter clutch so will see how things look after that.

Pulled it apart using $20 flywheel puller from ebay, found the spring inside the starter clutch failed, new starter clutch quoted at $160, too much for me! went to local bearing supplier found suitable spring in an oil seal part number 50 58 4 paid $7, need to unclip spring and cut @10mm off the spring and reclipped spring. i tested the fix in the hand to see it it grips oneway slips the other, note: use only minimal tension as required on the spring to engage it, due to it needing centrifugal force when running to stop it dragging and wearing. Dont forget to locktite the flywheel to starter clutch bolts. Hasn't missed a beat in 4 weeks now.
