uni air filter.

the whole fully built 146.





well this weekend i rode a kawi 138 stroked engine so a 155.



what gpx engine will match that power cause my 146 doesnt get near it.



say i get the yx150 engine. what do i have to do to it to get it to match or greater the power than the engine i rode this weekend.

Call SGR-usa.com and get a YX 150 with the tb 165 bbk. It will rip He has them in stock and ready to go.

Here is the brake down. 2 riders Minimxracer and washracer_11 both about the same size and both A riders Minimxracer has the 138 stroker with +R head, and PE 28 (a bad a$$ bike) I'm not sure which cam he has and Washracer_11 has the GPX/YX 150 motor that comes in the X4R with stock 26mm Molkt carb, just a +R head with S25 cam. The motors are dead even.



But if you really want to haul a$$ get the GPX/YX 160 that Pitster has and put a +R on that. That set up is fast. Or send your 146 to someone and have them make it a 18hp motor.

I have a TB 165, stock ported head and PWK 28, its just not as fast as the GPX/YX 150 with +R. I really like the motor but it just isn't as fast. I want more but right now my bike is propably better for my riding style, my bike is still easy to lay down in a turn.
