rebuild or not?

[bansheeshannie]

I rebuilt my banshee about 1 1/2 years ago and its still running alright but it doesnt feel as quick as it used to be. I know its about time to rebuild it again but someone suggested to just replace the rings if the cylinder walls arent scratched. what do you guys think? And also i cant get it to run just right with leanness and richness..if i run 350 jets its too lean and with 360 jets its a little bit too rich, what should i do with that?

you can't just replace rings I dont think. I think you at least need to hone it.

I wouldnt ever just replace my rings. When its time, I just a fresh bore with some wiseco's. I think that's what you should do. It's always better to be a little rich than too lean. Try messing with your needles. See if that doesnt help out.

If U r going to do it right just do a complete top-end, Jetting is the biggest key to having to rebuild all the time...

 

Don't what ur plugs look like.. I would try adjusating ur needles and air screw.....

 

And welcome to the HQ

a rebuild now will be cheaper and waaaaaaay easier than a rebuild after a blown up or burned up piston. just my .02 cents.

I wolud start with a compression check. With no head mods, and stock compression height pistons,your cyl pressure should be 110- 130 psi.

 

where in the rpm range are you having problems with jetting.

Main jet 3/4 to full

needle 1/2 to 3/4

pilot 1/8 to 1/4

air screw idle to 1/8

 

Hope this helps

i have wiseco pistons and its bored about 2.5 over...but im having jetting problems at lower rpms
