if I am looking in future for about 43cc gas 4 stroke motor... which companies are in that market?

Fox and First Place Engines quickly come to mind.

He said four stroke?

there are no 4-stroke gas engines, well saito has a couple in the 20 and 26cc range but they want some coin for them.

There are some RCS Moki type four strokes now sold by Troy Built Models

TBM has 4 stroke engines. http://www.troybuiltmodels.com/ns/ac...dex.shtml#moki

There's the 50cc single towards the bottom of the page. close to $1000

shot dude for that site...

I raced past the 4 stroke part. oops.

ouch I stand corrected, I think I'm gonna have to try one. 180 bucks for a 17cc is almost cheap enough to just experiment with and throw on a 60 sized trainer for familiarization.

These guys list a 50cc single

but nothing in the 40cc range

Don't know anymore about it i'm afraid.
