Can you use a 24mm intake on a head with a 20mm intake port/gasket?. It would seem to me the abrupt change in diameter would create an obstruction severely restricting flow

RcWannabe

Your thoughts are correct you don't want any steps in your intake tract. It would probaly run but it will cause a horrible stumble when you try to crack the throttle.

NCNSR

Oh #%# great !!

NCNSR

Is there any sane reason someone would send you a motor with this setup? Maybe i am missing something?

NCNSR

And here is another dilemma i am using a 12 position spacer to turn the carb and that is 24mm how do i get this all to line up?Cant the intake port on the head be bored out? Or can the throttle positioner be installed on the head and the transition bored smooth?

just run it. who cares sounds like for your application its not race, so ittl work. may lose a hp or two but itll move

NCNSR

A horsepower or two is the whole point if that didnt matter i could have just gotten a dead stock lifan 110 the whole point of getting this motor was the horsepower or two.

BlackBeard

okay well the straight shooter answer is you need to port match your intake to the head. send the head out with your positioner, and intake and pay 100+ to have it all ported in sync

NCNSR

If that can be done that is fine by me are you sure it can? (Is there enough material around the intake port to remove?) P.S How hard is it to remove the head for a novice........
