This saturday im going to dyno my 350x and 400ex/cr500 conversion. This is my built X but the engine is worn out, piston is 4 years old but she still RUNS. We will see what the numbers are like. :thumbsup:

Because the curosity kills me. Its still fast, but whatever number i come up with i know i can still get it higher with the igntion, and new piston. leaves me room for improvement.

Well i didnt get to run my X, it was going to be a bit too much work for how many people where in line to run. So no 3 wheelers on the dyno this time.

But for your info, The cr500 conversion, pulled 51.50. It was getting higher each run but i told them to quit runnin it, The carb had leaked a bit, and the subframe was hitting the brake roter casusing sparks.

The 450 got 44.42, pipe, intake, cam, 16:1, ported, igntion. The cam has alot to do with the low number there.

A year ago my shee pulled a 48.9 on the same dyno.

How does your 500 stack up against the other 500's around here?

if they did test just the motor i doubt it was tested at the crank....more likely the dyno hooks up to the motor with a chain....just a guess
