Default RE: checked my compression

i checked all the springs and as far as i can tell they are all back in ok. when i get on the gas it runs great. im still getting a little unburnt gas in 2 cylinders though. but it has much better throttle response. i am still thinking ill need stage 1 jets and a sync. im just not looking forward to the $500 for the labor on all that. how hard is it to install the new jets? i know what i just did was easy but with the new jets is it any different?

See if your plugs are still good. Maybe your not getting spark all the time.

IMO, a jet kit isn't your next play. The bike should still be able to run and burn all fuel without the kit. I have D&D slip on and K&N filter and my bike runs and burns fuel just fine. Like just mentioned, try a new plug. BTW, the manual says that if you are not getting the compression recommended you should put some oil (2 oz i believe) into the cylinder and retest. Have you gone over the troubleshooting for low compression recommended in the manual? I would do all of that before any upgrading.

did you run fishing line or something through the jets and soak them when you cleaned the carbs??

Oh, you're not talking about the good ol Do It Yoursef version. Personally, I would stick to air. If you suck up Mercury you're in big trouble.
