Well just sold my bike and got a 2001 blaster. My question how long can you go on a top end on these engines? Before your pushing your luck. The fellow I got it from had it a year with out a rebuild. Still has good compression.
As long as the carb is jetted correctly and you run a good mixture in your gas (32:1 is what most people run). They run a long time. There are people on here wtih 8 years on a rebuild. As long as the compression is good, about 120, then it's fine. You take care of it and it'll take care of you. And WELCOME to the forum!!!
Wow didn't think you could go that long! Ive been redoing the top end at least twice a year on the bike I sold. Just started liking the blaster a lot more. I'm running 32:1 klotz Super TechniPlate seem to give me the best throttle response on past bikes Iv had.
when i got it no work had been done to it i was suprised to find that the stock piston was still good it only needs rings even the walls on the cylinder still look good that was 9 years with oil injection with aparently not a single problem
