Default Re: Is a Brass Bushing Engine not as fast?

I ordered some new brass bushing form, haven't used one yet, but I'm gonna try one in the Karaoke bike engine when I have time to pulll the jug and do a little port work on it and notch the intake side of the piston, I know how the engine runs now so I will see if it balances it any and what the overall performance is with the bushing instead of the needle bearing.

No doubt that a bushing with have more friction than a needle bearing but it may not show up in the performance of the engine if a quality 2 smoke oil is used and the lower of the engine is in good condition, may actually quieten down the top of the engine also.

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