Hey guys wheres the best place to get the shims for the shim under bucket kit? I have to adjust my valves. I have the web cams .425 lift. They say to set them up at .006 valve clearance do you agree? Pro's and cons to different clearances? O and i got to race my buddies built banshee this weekend and i beat him every race by about 6-7 lengths in 250-300 feet. Man was that fuunnnn![img]i/expressions/face-icon-small-smile.gif[/img]

 

They are the same as the ones used on Kawasaki street bikes. My problem is I have .006 on the left side of the engine and .003 on the right side. what you want is between .004 - .006. http://www.cyclewareables.com/pages/...valveshims.htm

 

are the shim under bucket the same as the kaw? the shim on top is a kaw, or 29mm. i've also been told yamaha has 29mm but haven't checked yet. when i put the cams in my quad the manual said .004-.006, then i called woods and they said maybe a little more, they said .006-.009, so i went with .006. glad to hear the out come of the race.

 

The shims for under bucket are 13mm dia.
If you can't get shims the right thickness, a local machine shop can grind the ones you have to the needed thickness on a magnetic base surface grinder.
Bomb spec is .004-.006, RWR says for the race cam lifts they recomend .006-.009. I set all 4 of mine at .009 'cause the clearance only gets smaller over time.
