dbdragracing Posted March 19, 2009 Report Share Posted March 19, 2009 I checked my compression today and my numbers were 110/108...are these ok? Mods in my signature. I've just been trying to rule everything out because the bike won't start...when I bought it about 3 weeks ago, it fired up first or second kick and ran awesome. Next Im going through the carbs. Thanks. Quote Link to comment Share on other sites More sharing options...

hercalmighty Posted March 19, 2009 Report Share Posted March 19, 2009 Next question what kind of compression tester are you using? It might be the tester if the numbers are low. Quote Link to comment Share on other sites More sharing options...
banshee_terror_ Posted March 19, 2009 Report Share Posted March 19, 2009 that could be true u may have a shitty tester but with your numbers that low with a shaved head no. but it should still definatly run with those numbers..... if you have spark and it still wont run check your carbs Quote Link to comment Share on other sites More sharing options...
