I need help!! I bought a 2001 blaster and it ran great for two days. Well the third day i took it out and i road it for about 10 min and i was going fast but not at top speed.. well anyways it just shut off and i could not start it again. So i took the to end off and it does not look like its blown but im not really sure..so if anyone could help me or tell me what to i would like that alot!!! thanks

 

Are there little nuggets of aluminum in your combustion chamber? Are the piston skirts cracked? If you skirts are cracked and your cylinder is fine except for light scratches, all you need to do is get it bored over and a new piston/ rings. $250 at the most to fix it.

 

Well you never said anything about checking for any gas. LOL jk! Check your plug.

 

get your cdi checked

 

You never mentioned checking anything. But the first things you SHOULD have checked is:
1) does it have spark?
2) is it getting gas into the cylinder?
3) does it have enough compression?
All of that should have been checked way before tearing the top end off. It might have been something like the switch has corroded. (no spark) You need to check the basics first!!

 

ALright well i did check the plug and it was fine and i am getting a spark..Im not sure how strong the spark should be but compared to a car it is week.. I didnt check to see if it was getting any gas because from the fill of my hand the comprestion is week.. but their are no metal shavings in the head and the only thing that is cracked are the pistion rings.. so anymore tips would be great

 

hmm. does it turn over?

 

Well if your rins are cracked like you say they are then I'd suggest getting it bored to the next size and an oversized piston/rings installed.

 

Hello,
Not trying to dis you in any way, but you do know the piston rings are not a complete circle and are supposed to have a gap in them.
