Default Re: Another new guy

What SB said os a great idea and ill add that it really helps to grind the flange hole so that it is more rectangular shaped so that the exhaust does hit the flat surface of the flange when it exits the port, even with it rectangulared it still squeezes the flow down but it will flow much better and on the engines I have done this to, it was a difference that could be felt in performance, the carb needs to be well tuned for any of these mods to make there biggest difference as well.

If the engine can breathe good and the fuel to air ratio is right the performance is really improved, speed and pulling power will be very noticeable.

Best wishes.

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
