Thanks for the vid man. Im doing a cam grind on a car engine and this is one of the only vids that explains why we need thicker or thinner shims. It may only be for a quad bike but it certainly gave me info into the whole shims thing. Thanks

@Fpvgt290 i am glad my vid helped for more then just what it was intended for LOL.

Man you've been wicked helpful. ive been watching alot of your yfz vids and have done nearly all (oil upgrade on my 04 should be done by the end of the month). When i start the quad i can hear a tick from the valve train, it does get better as the quad gets warmer, but it makes me nervous none the less. so im gonna check the valves. My concern is if/when i remove the cams, whats the best way to keep the chain from falling, and the best way to reinstall the cams in time.

[Tooextrememx]

@crximportrider wow sry i missed your post it didn't show up in my inbox. well this may hit you a little late but what i do is tie a string threw the chain and to a wrench i am not using and let it hang to the exhaust side. getting the cams in when putting them back in is tricky be paitient and take your time doing it you may have to get 1 set perfect befor working on the other.

hey do u know if the cheat sheet is used on a 1999 yzf400 too i need to do a shim replacement and needed some help with it

[Tooextrememx]

@coldfusion189 i believe the cheat sheet would work with any shim style valve system you would just have to know what your clearances should be.

Hey man thanks so much for this video! I've been searching and searching for a decent valve check/adjustment video for a long time and no one ever seems to explain it step-by-step and clearly enough. You did a really good job and I completely understand it all now, thanks ! Luke

[nikolajdk1234lol]

[bistakos1]

all your videos are very nice and make valve adjustment so simple.thanks

ps.i guess if you go to a garage they will put you shims for 0.24 for WELCOME AGAIN give us your money! xaxaxaxaxa
