Ever heard of this??

[deerebill]

Hi,my name is bill and I am new to this forum. I have a two fold question about my CF moto V3, I have about 9k miles on it and just yesterday on the way home from work the crank broke just behind the vereator. I am now tearing the bike down to repair it,and was wondering if anyone has installed the big bore kit and is it much different.
Question#1 ever heard of a crank breaking on a 250CC
Question#2 is the big bore kit worth the money.

Thanks
Bill

What engine exactly does this "scooter" run with? A number or at least a picture would help identify it, because there are only a hand-full engines mounted on all "different" Chinese bikes.

Krasi,
The engine is a CN250 Honda clone from a Qlink 250 V3, the crank broke clean just behind the vireator. I had thought that as I have it out and apart would be a good time to add the big bore kit, if they are at any advantage.There is one on e bay for $200.00 and that includes shipping.I need some feed back on that. I just can't figure why the crank broke, unless I just had a bad one.
Thanks
Bill

I don't know how's do big-bore kits behave on these engines. But they (the engines) are cheap enough, so I would go for it.
