Re: Change your CG250 67mm air cooled engine (167FMM)to 70mm bore,Kit include piston
Yeah thats what I thought Barnone, I keep looking for anything on that 400 you posted in Gardos thread but didn't really find anything of use.
That being said what could be done to this motor to pep it up a little other than a freeflowing exhaust and a rejet. Can there be any gains with a better intake/air filter? Has anyone done any work to the head, cam, ignition in one of these?
I really don't understand all the EPA restrictions with motorcycles. In the US it is not a primary source of transportation plus the fact that it's a tiny single cyliner. Compared to our cars and trucks how much polution can that little sucker spew out? It's funny cause here in NJ you don't have to get your bike inspected anymore. Anything goes, loud pipes, no checking your exhaust gasses if it's within "spec", probably could just run with just a horn and headlight, no signals.
Forgive my ignorance with regards to these motors, this is all new to me, China bikes that is.

JK3,
That engine is actually a clone of a Honda engine so nothing unique about it being a China motor. I don't have any EPA restriction on my DF now.
I upped the main jet to a 100 over my DF's stock 88 but according to Gardo you already have a 98 but it might be worth a check to verify that. I put a washer under the needle to richen up the mid range.
But we still have a push rod 229cc engine and there is not a lot of power to be had there.
I tried chasing this one down but no luck.

Probably not worth the expense or trouble going to a 70mm bore to get it out to about 250cc. I'm looking for a 400 to 600cc air cooled single that will fit in the frame.
Did you ever find a bigger engine that fits in this?
