i had a 2007 CRF250R... i got rid of it because it honestly gave me nothing but problems. my buddies bought wr250fs and we rode mcnutt every monday, and it seems like 2 days of riding and id have to set the valves on my bike. when they ddint have to do anyhting, just oil change and air filters etc etc...
so now im looking at getting another bike for the upcoming season of riding. ive rode my friends wr250s and i dont like how heavy it felt.... im looking at 450s now and was wondering what peoples takes are on 04-05 YZ450F's? how are they on maintenance will regular oil changes and filters be enough or am i going to have to do alot more every week to keep it running nicely?!
