I just Bought this 1997 Yamaha Blaster with some mods done to it about 2 weeks ago. it ran exelent untill one night i decided to take it up and down my block when suddenly i loose alot of power and it wont rev up a minute later it dies .. and i have a look at my fatty exhust and its glowing RED HOT.
I waited for 10-15 minutes before i tryied to start it again and the piston i guess was siezed/jammed.
i then pushed it home and tryied to move the kick start, wich then finnaly budged with an ugly scratching sound comeing from the engine. it also felt like there was no commpression like there used to be. it has crank case oil i do mix my own oil/gas to the correct ratio i also bought a new spark plug problem still there.
maybe a gasket? ive been told.

 

You need to remove the head to inspect the piston/cylinder.
It could be a head gasket (I just fixxed a blaster with a gasket problem).
I think the piston siezed. A look inside will tell alot. [img]i/expressions/face-icon-small-smile.gif[/img]
