My front Sprocket was wobbling as well , And when I removed it i noticed that the ** INTERNAL SPLINE ** Had wear on it !!! So i replaced it with a AFTER MARKET Sprocket I Also noticed it is Held in Place with a
** SPRING WASHER ** Between the Nut and the Sprockett. The Spring Washer is supposed to be Slightly CUPPED so when you Tighten up the Nut it put's Pressure on the Sprockett to Hold It in Place ** take out Wobble **
The Washer on My 954 was flat
so i showed to the Local HONDA Mechanic and he told me it is a Common Problem
and to replace the washer and it would take out any Wobble.
It took it a Step further and MACHINED up my own Washer out or 4140 steel and made a COUNTER BORE in the washer with a 1/8" land that fit's against the Sprockett . This does the same thing as a spring washer but will never collapse!! I noticet I have less Drive train Lash and It also is a Bit smoother as well ,
I used to Have a bit of a Clunking noise in the Chain when I Have the rear tire of the Ground on my rear stand When I was rotating the rear tire by Hand to clean / lub the Chain , This has also Gone away as well!!!!
Since then I have done the same Mod to two of my freind's 954's with the same result's!!!! ** so check out ** the washer ** , Put a straight edge across it if it's flat REPLACE it and you will have no wobble and a less noisy CHAIN DRIVE.
