i was reading about tengra's motor stuff and they said not to go over .80 on a factory yamaha blaster's cylinder.is this true?[img]i/expressions/face-icon-small-confused.gif[/img]

89 blaster race ready

 

trenga doesnt recomend doing that. if im right i think they said the most to go over is .60 they said anymore wound have overheating problems

 

yes they are right.....just leave it to me to be the test dummy for it.
mine was bored .80 over and now its blown all to hell because the cylinder itself heats up to quick and breaks the oil down faster and the youll need a new cylinder cause it locks up and warps the clylinder itself. i mixed my oil 32:1(very thick) and my engine didnt last me a month of riding....whichs adds up to about an hour a day of practicing.
Just my opinion though
