Aussie Quad Racer Posted December 25, 2003 Report Share Posted December 25, 2003 that sounds like b/shit. The fact that you say in you sig that you have a full drag port it should be alot lower. i suggest you try another gauge. Quote Link to comment Share on other sites More sharing options...
bignasty1 Posted December 25, 2003 Report Share Posted December 25, 2003 yeh i would check that out with a diferent compression tester i dont see you haveing that much comp with that kinda porting and 20 cc domes. jmo tho. l8ter man Quote Link to comment Share on other sites More sharing options...
bignasty1 Posted December 25, 2003 Report Share Posted December 25, 2003 i just re read your sig and i am gonna have to call bs on what you got goin on. why would you run 2 diferent size sets of domes. you either have a big bore and need the domes or from what i understand you dont becuase you have no big bore and if you did have a big bore i would think you would need to run big bore domes all the time and switching your domes out every time you decide its a big bore or not does not make sence. i dont know maybe i misunderstand what you've written. l8ter Quote Link to comment Share on other sites More sharing options...
q8bizkit78 Posted December 26, 2003 Author Report Share Posted December 26, 2003 yes i use big bore domes cuz my pison is big i can use both of them plus alba action recomeneded that i use big bore dome the thing is whats the best comp for drag racing i dont want 2 lose top end Quote Link to comment Share on other sites More sharing options...
bignasty1 Posted December 26, 2003 Report Share Posted December 26, 2003 hmmm i never herd of runnin big bore domes on a bike thats only been bored 80 over i know 2 bikes that are and they dont run big bore domes but if it works it works. i guess u would be okay runnin the higher comp as long as you use race gas and have your crank welded i know that once you go to high on your compression you can actually loose power becuase the engine cant rev out properly but i guess if it runns better with the highest comp you can get then run it maybe you should try out a set of like 19's if you want a lil mo power but with 230 lbs i would worry bout my crank trashin itself cuz the comp is to high... could be wrong there are more educated ppl on here then me tho so maybe some one else could answer your question.
