how much of a power gain would i get with a yoshi comp full system for my z250. how much of a speed increase??

 

top speed will be the same you will just get there a little quicker.

 

he'd prob. gain 2-4 mph on top end and get there much quicker.... alll Yoshi systems are good so id recomend getting it.

 

thanks for the reply zblaster..i thought yoshi systems were pretty good[img]i/expressions/face-icon-small-smile.gif[/img]

 

theres this thing called a rev limitor which will only allow you to go a certain speed.

 

The amount of RPM's determines the speed and a Yoshi pipe doesn't allow the engine to get to higher RPM's, just get up to the maximum RPM's quicker. So the yoshi pipe will get you up to top speed faster, but it won't increase the top speed.

 

Not necessarily true. The stock pipe could very well restrict the engine from providing its peak power or is keeping the engine from hitting the CDI's peak RPM(rev limit). The pipe will most likely raise speed and how quickly you get there. A pipe on a four stroke is almost always a great upgrade.
