A forum for owners of Yamaha TTR250 trail and enduro bikes!

I have had a number of requests for valve shims so we are now stocking them at Totally TTRs - see http://www.ttr250.com/TTR_extras/#shims

I hope that will make life easier for owners who do their own valve clearances.

It is easy enough to do if you have are methodical and have a bit of patience - and a decent torque wrench 

I bought a set of feeler gauges that go up in very small increments and allow very accurate measurement of the clearances - a highly recommended workshop investment!

Although there isn't a pictorial guide to adjusting valve clearances, most of the work is covered here http://www.ttr250.com/Removing_Cylinder_Head/TTR_head_removal.htm
