Anyone done it or know how to do it in the Arlington area? It's time for an adjustment and I have no clue how to get it done.

Thanks

you have to place shims under the cams to adjust . they make kits with different shims so that you can do it... I have some in stock I am in Waxahachie.

the feeler guage should have semi tension on it, you shouldnt have to push so hard it moves the spring to get the gauge in there.....

Save your pennies after the first adjustment you are just on borrowed time.

titanium valves without nickel bronze seats why yamaha did this i have no idea. Once the lash starts to tighten up it doesn't take long before $500 worth of Ti valves are junk and lipped up. Kibblewhite makes a stainless conversion package that we've done several times.

you know, i have known alot of people with Yamaha's and none have evey had a problem with valve lash. now the early CRF's did, but i thought the yama's did not have the same fate.

I have a dirt rider from last month that explains everything you will need to know about adjusting, re-seating, or just about everything needed on valves. Shows an in depth step by step for cutting valve seats even. The article is called "Get your head checked" or something.
