hey so currently i have put a lot of money into my 03 cr250. new plastics, all new bearings, new suspension seals ect. and now im considering doing a conversion. keep my 03 cr250 motor as a spare and drop a 2001 cr250 motor in it. i know i would need differnt swingarm collars, 01 headstay, 01 pipe, 01 cdi, 01 cooling system. so do guys think its worth it? im finding 01 motors on ebay for 500-1200 bucks. So i just want to know what you guys think about this conversion and do you think its worth it? 01 a big of enough difference?
