crf250 big bore

just looking for some feedback thinking of fitting an athena 290cc big bore on my 05 crf250 been told that 08 oem or stage 2 cam works well but the 08 oem cam is lot more exspensive any help please .thanks jason

A+ set up, however its not a 290 kit that is for yamaha's the athena kit for a honda is 280. If you shop around you can find a brand new stage two cam for $125 like I did and sometimes there are brand new athena 280 kits on ebay for around $400. stay away from the cylinder works big bore or what ever its called. its cheap.
