AJC Posted January 8, 2008 Report Posted January 8, 2008 (edited) what should my compression be at sea level? im going to test it tonight to see if i need a rebuild or not. thanks Adam oh and the motor is a stock 03'.. Edited January 8, 2008 by AJC Quote
Hilarious Posted January 8, 2008 Report Posted January 8, 2008 Back when mine was stock and unmolested, at 150 ft above sea level I had 127~130 psi in each cylinder. Quote
csrmel Posted January 8, 2008 Report Posted January 8, 2008 on a stock motor i would say 110 or less and its time to order parts for a rebuild but you can still ride it if it start ok. if its below 100 then dont even ride it or you risk damage. just put it away until the rebuild parts come in.

AJC Posted January 9, 2008 Author Report Posted January 9, 2008 (edited) i guess its time for a rebuild than 94psi on each cylinder. should i go with new pistons or just a new set of rings? and ps: bike starts perfect. first kick. dont know if that has an affect in anyway Edited January 9, 2008 by AJC Quote
BansheeKid15 Posted January 9, 2008 Report Posted January 9, 2008 I would say, just get the rebuild kit. No sense in taking everything apart to replace one thing. Best just to have the piece of mind that everything is new IMO... thats what im doing... that and getting it ported Quote

The size of the domes you would want depend on your elevation and what type of fuel you want to run ( pump gas/ race fuel) Talk to David at Noss machine and he can help you determine what size domes you need. The o-ring kit comes with it along with acorn nuts and washers. It works with your stock studs. Quote
AJC Posted January 10, 2008 Author Report Posted January 10, 2008 ok thanks i sent him an email.. no reponce yet though. but are these even worth getting?.. do they do anything at all besides cool the motor better? such as add more power? Quote

Well, I just installed mine the night before last. I got home from work yesterday and took it for a test spin and right away I noticed a nice increase in bottom and mid range power. It pulls a lot harder from the bottom of the powerband to the top with crisp power. I'll have to wait for the weekend to get more riding time in on it, but I am very satisfied with it already. I think it is a very good investment. Quote
fastrthnu Posted January 10, 2008 Report Posted January 10, 2008 Sea level is your friend. Even more so,... cool 40-50 degree seal level with no humidity. Sea level and pump gas a 21 cc is good n safe. Noss heads are the shit! Quote
AJC Posted January 11, 2008 Author Report Posted January 11, 2008 so whos the best company to deal with here? ive been comparing prices and they all seem pretty close. 10 to 15 bucks off some. F.A.S.T Racing or Noss Machine? so.. i would need. The cool head domes acorn nuts orings that it? roughly 300 bucks along those lines? Quote
csrmel Posted January 11, 2008 Report Posted January 11, 2008 it isnt worth it. just get youre stock head reworked. alot of places will do that for $50-$80. Quote
