you know a chassis dyno will do wonders for finding the right tune-up. they will hook-up an o2 sensor and you will find more horse power for sure. now i know there has been alot of talk about dyno numbers from chassis dyno to another chassis dyno, but it's about the increase in power that matters not the whole number for bragging rights. make sure he has jets or you take a bunch along and go nuts, IT WORKS!!!!

 

so can he buy one or not. and as far as keeping up. i've raced 4 ds 650's and haven't been out run yet. but i have been out run by some 250rs and a few banshees.[img]i/expressions/face-icon-small-cool.gif[/img]
