Increasing displacement is going to give you more low down "oomph". You won't have to rev the motor so high to get the power, compared to trying to get more power out of 125cc. The setup I mentioned earlier is going to feel dead under 6K rpm, but in a race - it'll smoke a 143cc bore kit mated to a stock head/stock throttle body with cam.In your guys' opinion, do you think head porting + koso TB is more reliable than say the takegawa 143 bbk?
I already have the chimera intake, dynojet pcv, after market exhaust, takegawa stage s cam.
Just want a little more oomph....
Farmboy, I was curious if you were able to make any progress regarding your head-porting inquiry?I will try to message DHM (Activ3)....
GromFatherz does a lot of porting work by request.Farmboy, I was curious if you were able to make any progress regarding your head-porting inquiry?
I was just thinking -- for someone who has the proper equipment and skillset -- this sure seems like a great small business opportunity: substantial demand, and virtually no supply.
You'll still see gains with the stock limiter. But you'll also be missing out on a lot of potential. You don't always have to rev it out to the max rpm if you to raise the limiter...you probably will tho cuz its so fun.Is there any benefit to porting the head and keeping the stock rev limiter? I ask because I feel like the more you raise the rev limiter, the more likely you're going to break something. So does head porting only result in gains at higher rpms? ie - is it worth it with a stock rev limiter?
That has been my experience also.Perhaps, but how does one go about making that “request?” My previous communication attempts have gone largely un-answered.
