Mikes XS

24 Tooth 5th. Pinion Gear. Replaces 23T 5th. pinion gear (OEM Ref. #341-17151-04) Gear fits to stock location and makes fifth gear taller (higher top speed in fifth but less torque and less vibration) but ratios in lower gears remains the same so that acceleration & torque in lower 4 gears remains the same. Cases must be split to install. This is a "Race" part and carries no warranty other than for defects in materials. Fits: XS650's 1978 - 1984 Only! Note: Yamaha changed the shape of transmission gear teeth from 78 on and this is indicated by lines cut into the crest of each tooth. This needs to be used with part #05-0857.

Clutch Pushrod (Short outer rod). - Stock part for 1976-84 650's but will also
work with 1970-75 parts.

Clutch Pushrod ( Long one-piece rod). - Replaces both inner and outer pushrod
and outer ball bearing used on 76-84's. Provides more stable action and allows
less wear of clutch pushrod seal (Note photo not to scale).
Fits: 1970-84 650's. Stock original type for 1970-75 models.

Clutch pushrod Bearing - Fits: 1970-84 XS/TX650's. 2 used in each 76-84 engine,
(only 1 pc. required if long early 70-75 type clutch pushrod is used).

Clutch pushrod shaft Bushing - Replaces original bushing inside of pushrod
housing (transmission shaft) and brings clearances back to original. When
stock clearances are too large the pushrod moves to the side and increases
tearing stress on the pushrod seal. (See our catalog for detailed installation
procedure).

Clutch Pushrod Oil Seal - Made in Japan by original maker. Fits: 1970-84 650's OEM Ref.# 93102-08094/08118 (SD - 8-25-6) Ars Note: The Clutch pushrod seal is a chronic leaker. This seal was made to be replaced when the engine cases are split! It can be replaced without splitting the cases but it is tricky to drive it in intact. We suggest riders purchase more than one as you will need another again someday if not right away if you do not succeed in replacing the seal intact. We suggest you also clean and polish your clutch pushrod as grit & nicks on the rod will saw away at the seal lip causing early wear.
