what should stock compression on a banshee read ?
its a 2000

[Yamahauler_04]

Should be IIRC 125 psi.

[250r4life]

depends on altitude, dome, etc...

[boredoutbanshee]

Should be 125 psi MINIMUM anything lower and you've got problems. Although the maximum you'll probably ever see will be about 150 and thats with lots of mods.

thank you for the info
and I do appriciate it.

I've herd 120-125, mines 195ish and both cylinders are the same psi, I was in shock they are usually couple psi off.

When you test it, make sure your throttle is wide open or you wont get a correct reading.

Max 150 with lots of mods?

Mine is at 195. I rebuild it at 150.

Lots of mods is an underatatement though. I have the full Paul Turner Eliminator kit from Duncan. Same motor they use in PDV, except I run the midrange pipes, not the high rev.

[450rJam]

its about 110 in each but I didnt know the full throttle thing.
Ill check again
It dont start too well after it has sit for a while, thats what lead me to think it may be about time.
This thing screams and if its about ready for a top end........
wow how much will it increase performance?
is there anyone who sells just the rings ?
the pistons or modded with some crazy large boost ports
I need to mic it and see where its at.
thanks alot for the help

ACTUALLY with a STOCK banshee motor, which is what he is obviously talkin about a normal compression range would be around 125. With a fresh topend you may hit 130 psi. And I've never seen a banshee hit 195, almost hard to believe. Remember, he's askin for STOCK compression, thanks.

Last banshee motor I had: 210 psi with alot of motor work, and 18cc domes in the pro design cool head.
