01bansheefox Posted April 9, 2006 Report Share Posted April 9, 2006 Ok where to start...... Bike ran 100% perfect one day, came back week or 2 later and only the left cylinder runs and the right will go on and off every few seconds, If you run it for 10min the pipe will still be cold and the other pretty hot. Also if you take off the left smokes normal and the right will blow nothing then all of a sudden blow out smoke like a mother then shut off again. 1. I switched both plug wires, still does the same thing 2. Put new plugs in and gets good spark 3. Has compression I did notice my right intake boot has a crack in it, but I cant tell if its big enough to suck in air but would that make fire on and off? Thanks Quote Link to comment Share on other sites More sharing options...
joker149999 Posted April 9, 2006 Report Share Posted April 9, 2006 (edited) if it's cracked i would say your sucking air, i would replace the boot, one way too find out is run it and then spray a little bit of starting fulid on the boot and if it spike's the rpm or raise it, it has a hole. but too me it sounds like you might not be getting fuel too that cylinder i would check your carb out if it were me Edited April 9, 2006 by joker149999 Quote Link to comment Share on other sites More sharing options...
01bansheefox Posted April 9, 2006 Author Report Share Posted April 9, 2006 Ya im thining it might be a carb problem too but if it was the intake boot would that make it not fire? Quote Link to comment Share on other sites More sharing options...
joker149999 Posted April 9, 2006 Report Share Posted April 9, 2006 i was sucking air on mine from the boot a while ago and both cylinder's were firing just a lot of back firing and it would not idle. but i would check your carbs for sure Quote Link to comment Share on other sites More sharing options...
01bansheefox Posted April 9, 2006 Author Report Share Posted April 9, 2006 Mine starts up fine but its only the left cylinder running the right side doesnt even make a noise and another thing after about 5min of running if I pull the plug out there is no oil on it and its not even warm.

Dinner Posted April 9, 2006 Report Share Posted April 9, 2006 (edited) Mine will has done that twice now, the right side will fire when i start it but the left wont, but i easily fix it. The next time it does that pull out the choke and it should start pinging like it should. Mine acts like the plug is fouled or its not even sparking, once i pull the choke out, it starts right up, then i give it gas and taping the throttle and she runs fine, see if this helps at all Edited April 9, 2006 by Dinner Quote Link to comment Share on other sites More sharing options...
01bansheefox Posted April 9, 2006 Author Report Share Posted April 9, 2006 Well i dont use the chokes in fact I cant because the carbs are so big i cant push my lever up or down both of them always stay down which I think is off, i have never touched them before.

joker149999 Posted April 10, 2006 Report Share Posted April 10, 2006 i wonder if maybe your efi box is bad then Quote Link to comment Share on other sites More sharing options...
01bansheefox Posted April 10, 2006 Author Report Share Posted April 10, 2006 But remember I switched the plug wires around to see if it was that and the left cylinder still fires perfect. Quote Link to comment Share on other sites More sharing options...
Sheenut Posted April 10, 2006 Report Share Posted April 10, 2006 Sounds like your not getting fuel to that cylander, I would stop running it until you pull the carb and clean it . no fuel to that cylander also means NO OIL. just my 2 cents Quote Link to comment Share on other sites More sharing options...
