SpeedRacer88 Posted May 21, 2013 Report Share Posted May 21, 2013 just put together my buddies bike 4mil dune port blaster angle 18cc domes shearers stock carbs 25 pilot 350 main uni filters sea level +4 timing bike runs fine (a lil rich) until 6th gear when right side dies I kill the bike and start back up and it comes back thought I was running the bowl dry but when I pull the plug they are wet so thought maybe I was soaking the plug leaned out the needle until I was visibly lean same outcome. I swapped cdi box and also tried swapping around plug wires and tried new plug caps set gap on flywheel insanely close same outcome both sides have good compression. Topend is new Crossover tube is installed in between carbs Any ideas? Quote Link to comment Share on other sites More sharing options...
J-Madd Posted May 21, 2013 Report Share Posted May 21, 2013 Carb sync? Usually an out of sync carb shows up right off idle unless it is way off though. Reeds? I would think it would be air leak if the plugs were wet, but pressure test wouldn't hurt. Quote Link to comment Share on other sites More sharing options...
SpeedRacer88 Posted May 21, 2013 Author Report Share Posted May 21, 2013 i would think that if it were low on compression it would show in the lowerer rpms and i did a leak down no air leaks carb sync is good reeds are good thanks for replying Quote Link to comment Share on other sites More sharing options...
J-Madd Posted May 21, 2013 Report Share Posted May 21, 2013 Is there any chance it's sucking water in the cylinder? And compression loss will show more on top. Maybe a stuck ring? Were the cylinders honed and chamfered properly? Which side is bad? Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted May 21, 2013 Report Share Posted May 21, 2013 Hmmm, a 25 pilot does not sound right at all. My girlfriends is a 27.5 280 on a SS trail port with fmf and k&n at sea level. what are the plug gaps at? What's each side of the coil ohm at? Could be a bad coil favoring the least resistant path. Some how I got a B8es and a b8ers in the same bike, resistor plug wouldn't fire. Just something to look at. Quote Link to comment Share on other sites More sharing options...
SpeedRacer88 Posted May 22, 2013 Author Report Share Posted May 22, 2013 Imma compression check it tomorrow with a guage I swapped the coil today. No go And I don't think it's sucking water I'm not losing any Sent from my SGH-T999 using Tapatalk 4 Beta Quote Link to comment Share on other sites More sharing options...
