2001 WR450 valve check
Posted February 03, 2006 - 08:23 PM
Im sure these are the standard 450 shims. My main question is, is there anything i should look out for or check at the same time I have the valve cover off?

Anybody know if the 01 426 uses the same diamter shims as the 450s?
I tore the 426 down, plus did a valve adjustment and oil change on a 2005 Yamaha V-Star 1100. The entire exhaust has to come off of that to change the filter, and almost everything on the top of the bike has to come off to adjust the valves. What a bogus day in the garage...

The carb had to be loosened and kind of twisted to get the tentioner out.
The biggest gotcha: The cam bearing retaining clips are very easy to drop into the motor when you new working on this motor... When you pull the caps up they just fall out. If anything falls in the opening between the left side intake and exhaust, its a straight shot down and out into the timing chain cavity. I had to fish BOTH clips out of the timing chain hole! One fished out twice. They are tricky to get in right. Now I know ALWAYS be careful of these things.
I have an inch pound torque wrench but it doesnt go down to 7 ft lbs... I did just guess, but I have pretty good feel for it. I didnt make them to tight or to loose. Hopefully.
The spark plug was a few months from being a permanent part of the head though. NEVER leave a plug in for 3 years without checking it!!!!!
Thanks for the help.
