Tc I got the spec from the yamaha dealer it was on a old flier, but I did
find it on the web also it is on ingo's yamaha vm@x world under "technic"
I would like to thank you for your help. I think that I'm going to put the
bike to stock and try it. Have you ever found a spec for a gas anilizer
when the reading are taken from the tail pipe.I have the yamaha book that
lists the spec's but it is to old and does not have a listing for the
vmax.
