I am currently building a GP Ultimate Bipe and it recommends an in-cowl muffler. I plan on using a Saito FA72 for power. Can anyone recommend a muffler for this engine that will meet this need and where to purchase one?

I'm no expert, and am hazarding a guess....

You're looking for a 'pitts style' muffler, and 'Slimline' shoud have one to fit your Saito. And is probably the best place to start..

I couldn't find a listing for a Saito FA-72 but I sent an e-mail asking if one was available. Thanks for the info.

Any other places to check?

I wouldn't bother with the expense and chance of causing running problems with your Saito. If it were a 2-stroke, yes, but not with a 4 stroke. Just mount your engine on its side and turn the muffler inward to exit in the cowl's air exit hole (bottom side).

The Slimline Pitts muffler for a Saito .65 to a .91 will fit the .72 In some cases you might want to block one of the outlet pipes for a better idle. - Saitos seem to need the backpressure.

I agree with Gary. Keep it simple. Don't go messing with a good thing and complicating it. The in-cowl muffler is for a 2-stroke. On my Saitos, I just side mount and turn the muffler down toward the mounting lugs.

I agree with Ed and the others. Keep it simple. Also turn the carb on that Saito around. This will put the needle on top along with the throttle linkage.

Simple it is then!! Thanks for all of the advice. That is the easiest way to go too.
