i have a 03 blaster and ride it everyday, hard and long. recently it seems to bog a little in 2nd and 3rd. could this be from my topend wearing out. please help. if notm do u have any ideas as to y it might be bogging? ive never maintence it other that greasing the fittings, chain and changing the gear oil.

 

how much gas are you giving it..1/4 1/2 3/4 w/o then someone might be able to tell you

 

more thank likely not, it isnt jetting because it would occur in all gears. so do a compression check and see how the numbers are if they are good post on here maybe we can help you through it. but i dont think it is to serious of a problem. the bore should be fine maybe it just needs a re-ring job and hone.

 

03 blaster...how many hr.?
