99mxbanshee Posted August 13, 2006 Report Share Posted August 13, 2006 I know my banshee needs rebuilding. Compression is 113 and 122 and its supposed to be rebuilt at 130. My question is would the compression alone cause it to run so bad that it wont idle or be able to ride it? Quote Link to comment Share on other sites More sharing options...

Dinner Posted August 15, 2006 Report Share Posted August 15, 2006 When i first got my shee it needed a new top end badly :baseball_bat: But before i got a new top end i took it out for a spin, and it ran like shit. It had no power, sounded bad and would only go like 45km/h. So after i got the new top end it ran reall gooooood Quote Link to comment Share on other sites More sharing options...
dajogejr Posted August 15, 2006 Report Share Posted August 15, 2006 What are your mods? Ported, bored, stock head, shaved head, aftermarket head?? 130PSI is about right for a fresh motor, stock...at or near sea level. My original motor in my 96 had 110 in each cylinder before I tore it down this year, and it didn't start great (normally took 8 or 10 kicks) but once warmed up, it still ripped. There's two rules of thumb on compression differences. 1 is 5 PSI of eachother, the other is 10% of each other. You're close to that....so, if this is a stock motor, head, porting...you're probably about due for a rebuild, but you might have a problem elsewhere as well... I personally don't think (given it's a stock motor) that the compression difference is such it'll run terrible or not idle... Quote Link to comment Share on other sites More sharing options...
