frocashmoney24 Posted January 16, 2005 Report Posted January 16, 2005 does it start all the time, first few kicks or does it take a few? have u felt a power loss? i would recheck, but if it came out the same, i would be doin a new top end. Quote

Bansheerider29x Posted January 16, 2005 Report Posted January 16, 2005 I would say after a couple more hours of riding its gonna run crappy and lose power when it gets hot. If you are that low on compression i would go for one last fun a** ride, then get to rebuilding the top end. Quote
1redram Posted January 17, 2005 Report Posted January 17, 2005 You might want to get a better tester. I just went through this with my bike. I bought a $35.00 compression tester and was shocked that I only had 150 psi. per cylinder. After calling Duncan Racing they said only use a name brand tester( Snap-On to be exact ). Well after taking my bike to my local shop and testing with a Snap-On tester the cylinders tested out at 180 psi. To make a long story shorter. Try to find someone with a name brand tester and see how things go from there. Nathan Quote
Otis Posted January 17, 2005 Report Posted January 17, 2005 Did you follow the directions on doing the test correctly? The first time i did a compression check, i just put the tester on and kicked kicked kicked...only got to 60.... Warm the engine up for a few minutes, and hold the throttle wide open while you kick it over....i may have forgotten something. I'm sure if you do a search on how to do a compression test it will tell u exactly what to do... Quote
fixitrod Posted January 17, 2005 Report Posted January 17, 2005 I used a really nice test (thanks boonman) to compare mine. I had two bad ones. I bought a new one and it reads the right compression now. Compression tester can be wrong. Being that they are 10% different though even with a bad guage, I'd say you are close to a rebuild. Quote
FIRST BANSHEE Posted January 18, 2005 Report Posted January 18, 2005 try checking them wet, squirt some oil in the cylinders hold the throttle opened and kick. see if there is a big change, if there is start pricing a topend Quote
SAMUNOWAY Posted January 18, 2005 Report Posted January 18, 2005 What is the compression suppose to be at? I've got 135 on one side and 132 on the other. I'm at sea level. I can't find any specs in my Clymers. Quote
