Just purchased a 2003 Blaster for $950. Extra quad for buddies etc. to go with my '08 Raptor 700. When we looked at it it seemed to be making some engine nois, piston slap etc. but then again many other Blasters seem to sound the same. Took it to the dunes on Sunday and piston seized.
Pulled it apart, piston skirt broke off and a piece was lodged in the crank I believe causing it not to kick over. My buddy pulled it apart so I did not see this myself. Cylinder walls/head look perfect. I'm going to get it bored the next size up as the piston seems a bit sloppy in there when we check it by hand. We will open the case to check it out and remove metal pieces etc.
My buddy has a kit to split the case but his bolts aren't long enough. Is there another way to split the case w/simple tools etc. or should he just get longer bolts? We figured since the rod may have a slight bend (looks fine naked eye)
and crank or crank bearings may have been damaged, why pay for someone to pull the crank/rod apart (becuase they are pressed) We just figured apply the $$ to a stroker kit. What stroker kit is recommended? I don't want to sink alot of $$ in this thing either. What kit can we use without having do modify anything else (trench case etc.) from what I read a vito's sounds good.
We are going to remove the oil injection system. Should we get the kit or save the $$ and follow the instructions on this site to block it off?
Any other hints or ideas when rebuilding this? My engine knowledge is limited.
My buddy has had several two-strokes apart but never a Blaster engine.
Thanks for spending five minutes reading this and any input is greatly appreciated!!!!!
