I own a 2003 Vinson with 1700 miles and need to do some service to it.

Need the spec on valve adjustment and where to line up the crank too when adjusting.

I am replacing the belt because the vinson slips after a guick hard stop .

Looking for info on clutch service on what to lube, mainly for the driven clutch.

If you could send me scan of the page from the repair book that would be great!


BTW; Folks should check that bearing in the clutch side cover. Had to pry my cover off damageing the bearing seal and retainer. Dry bearing too.

 

valve clearance for 03 Vinson from Suzuki Service Manual
IN .05-.10 mm or .002-.004 in.
Ex .17-.22 mm or .007-.009 in.
these are cold clearances

Valve clearance is to be checked when the engine is cold. The intake and exhaust valves must be checked and adjusted when the piston is at Top Dead Center of the compression stroke.

-Turn the crankshaft until the piston reaches TDC on the compression stroke by turning the starter cup. (behind the recoil starter, it must be removed.) Turn the starter cup until the line on the generator rotor is aligned with the mark on the crankcase.

-The crankshaft can be turned to align the line and mark by slowly pulling the recoil starter rope without removing the recoil starter.

-Insert the thickness gauge to check the clearance between the valve stem end and the adjusting screw on the rocker arm

 

Thanks for the info.
