Has anyone dyno'd any DRR50's with motor work that you guys know of? I also here allot of Billy in the 90cc world.

I would like to see some graphs if at all possible so I could compare them to the stock runs I have compiled.

Thanks

honestly your about the only one we ever heard of dyno testing these motors , most every one has done it the old fashion way trial and error, and error , and error, but there could be someone else

I personally like to get them running perfect and then try like 5 more things at one time so it runs a lot worse

That way I get frustrated and ruin my weekend...

Anyone on board?
