i checked my compression and its at 125 psi. is that good? it will start with one kick but its real slow. so slow i cant put it in 2nd --like 5 mph. can some one help.....
What is your compression????
- Thread starter PUDDKILLER
- Start date
its normal compression for a stock blaster.. if you want to go a little faster or get more gear out of it put a 14 tooth sprocket on the front that will help..
i think is a stock eng. the book said 140 - 150 psi is the normal compression and i have 125psi. it rev's up good but when i put it in 1st ihave to give it alot of gas. then it bogs down so much i cant go fast enough to put it in 2nd.
it's like theres no power after i put it in 1st and its not sliping. can it be my reed, or jeting is bad????.

IT could be great with some feedback from the members of the forum.

thanks

None since its in the shop but before she died it had 70 psi and still ran.. Then dropped to like 15 and found out my topend went.
haha lol! (I know its not funny!) But no thats definitly not good..
120-130 stock... something has major wear in your machine.. properly rings / piston.. maybe it need new bore.. does it even start with 60 psi?
So far we can actually conclude that a compression of 150-180 almost.. is very good .. lots of power to come at you!
And anything under 120 is not good .. parts are wearing out..

Nobody on here SHOULD need to run anything higher then 110, unless they have an all out drag motor that absolutely has to have it.
