OKCterror Posted November 23, 2008 Report Share Posted November 23, 2008 Put on new coolhead and other goodies then ran it out at the local spot last weekend. No i can turn the engine over but i have 0 comp. Kick starter is super soft and i cant get the engine started. Should i rip apart the head assembly or what. What should i look for and what do you guys think it could be.-Dan Quote Link to comment Share on other sites More sharing options...
shee4speed Posted November 23, 2008 Report Share Posted November 23, 2008 did it have compression after the head was put on? Your gonna definately need to pull the head and see whats going on. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted November 23, 2008 Report Share Posted November 23, 2008 As said, start by taking the head off. You could get lucky, pinched or smoked Orings. Could have a melted piston.... Quote Link to comment Share on other sites More sharing options...

OKCterror Posted November 24, 2008 Author Report Share Posted November 24, 2008 well the kickstarter was soft after i put the head on so i dont think its a big problem. COuld orings bed bad Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted November 24, 2008 Report Share Posted November 24, 2008 If the combustion chamber o ring was bad I would think that the leaking compression would be going in to the cooling system. That would cause antifreeze to puke out of the radiator. josh Quote Link to comment Share on other sites More sharing options...

OKCterror Posted November 24, 2008 Author Report Share Posted November 24, 2008 yeah it was, you offering? Quote Link to comment Share on other sites More sharing options...
ZillaRider02 Posted November 24, 2008 Report Share Posted November 24, 2008 yeah it was, you offering? I'm guessing with no compression, it wont run right now.....You were asking $2500......What's it take to buy it right now? Quote Link to comment Share on other sites More sharing options...
OKCterror Posted November 24, 2008 Author Report Share Posted November 24, 2008 that was also before i put the 900 in parts on it. 2200 delivered. with all the plastics and wheels and spare parts too. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted November 24, 2008 Report Share Posted November 24, 2008 2200 for a bike that doesn't run and has no compression???? Quote Link to comment Share on other sites More sharing options...
spurdy Posted November 24, 2008 Report Share Posted November 24, 2008 I don't think I would be banking on a bad o-ring. I used to run a 17cc dome and ran VP Red due to the compression. When I was running pump gas I ran a 21cc dome. I think anything less then a 21cc dome would require at least a mix considering where you ride unless your running a higher exhaust port. I think it could likely be a hole in a piston based on the information posted. SP Quote Link to comment Share on other sites More sharing options...
