Too bad you could not have done some tests before doing the jet changes.

My Trail Tech Vapor came with a temp sensor that fits under the sparkplug. What I found was that the temps from there changed vey dramaticlly. For instance, long run at WOT, temp would go to near 400 degrees F. My first thought was if I let off the gass it would cool quickly. Instead the temp shot up another 25 or so degrees almost instantly. (It just went lean) roll on the throttle and it woul cool down just as fast maybe 50 degrees or so.

It did seem that the overall hi temp was reduced by about 5 degrees after I reduced the restrictions in the exhuast and went to a Uni-Filter and a jet change 2 sizes bigger.

I think a oil temp gauge would be most usefull on my bike.
