My 06 blew up in march due to waiting too long to rebuild 35 plus c rider started at 34 now 40 didnt think it would need it. Started in 04 on a 250f rebuilt once. Maintain bikes well new oil and filter every 3 to 5 hours. My boy just got a 09 250f I got the 09 450. Did the 06 oil filter install gromet to the motor or cap. Put my 09 filter in gromet to motor and it locked up. Thought I remember them going in like the 250 in 06. My bad, what a bonehead. Someone tell me about the 06 sold the bike and manual.
