True 250cc upgrade?
Does anyone know of a true 250cc cylinder head and jug that can be found?

229 is the max that the CG can go. Remember that the CG was born as a 125cc.
What people do to get more juice out of the 229cc, they put a crf230 piston, they workout the carter to make it a bit bigger, custom cams, custom connecting rods, port and decked head, better mufflers, better carb. When fully customized they can reach quite decent speed (for this type of engine), also they can reach about 62 mph in about 8, 9 seconds, which may not be too fast if you are used to bigger CC motorcycle, but again it's just a 229cc |
Thank you for the input wild dog, I might check out the 230 piston, my head is decked and exhaust has been evenly ported. I can run 65-70 on a good warm day comuting to and from work! Thought I'd just reach out there and see what I got back.

There are bigger versions, but they're liquid cooled. They're commonly used in utility trikes in Asia and Mexico, with a tilting box over the rear axle. Jury is still out on the actual displacement, but it's likely between 250 and 270.

Do we have a source for these custom cams?

Well isn't that cool!!!?? I'd love to cam the TT. Then it would really be worth the porting.

My difficulty is in trying to even order the stupid thing. Even with a translating program, the websites aren't setup to take international orders and sending e-mails is proving difficult. I almost wish they had a third party broker website like taobao to place an order through. |

They have 2 different custom cams in their records but you gotta call them. Cleveland Cycle Werks got it through them. I dont know the cost but those Brazilian ones sound pretty goood |
My large limiting factor is my clutch right now.
