Too bad we can't do it like this:

AdvancerMan.com

 

that lexan cover on the site is damn cool.

That aside I have a +4 on the ninja from factory pro and honestly I can't tell a difference. Of course 90+ ponies from the get go it can be hard to tell any marginal increase from the butt dyno.

 

True.

Is it from AdvancerMan? He claims some other brands are manufactured wrong and are not delivering the correct timing

 

no its from factory pro. bought it about a decade ago. it appears to be a correct design, the tooth to trigger the ignition pickup is spaced differently than the stock one and appears to be in the advanced position in relation to the rotation of the part.

im sure there are some cheapo "advancers" out there especially with the rise of china ebay trash in the last 10 years or so.

 

Maybe jhoffy22 is going to try this mod and report back. Most of use remember the 351 install he did.

 

Aww..

 

1994 KLX250R air box boot has the bulge in it as it goes around the shock btw. Maybe that's worth the higher hp rating?
