Hey, seems like a great forum you guys have!! I just picked up a CRF50 roller with some aftermarket suspension on it, and I'm looking for a motor to stuff in it. I have a TTR 50 with an 85 kit, and I definately want to go bigger than that. I saw these LIFAN 125CC ENGINE MOTOR HONDA CRF XR50 CRF50 Combo Kit : eBay Motors (item 260554690409 end time Feb-23-10 23:17:45 PST) Lifan 125cc motors on fleabay, but the $300 price tag seems insanely cheap. I was wondering what you guys would reccomend for a decent complete motor kit that isn't really pricey? Thanks guys!!
