ginger Posted November 11, 2011 Report Share Posted November 11, 2011 any more info, do you have the TORS still, if so, unplug them. What all was changed, ECT. Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted November 11, 2011 Report Share Posted November 11, 2011 Check compression and spark. Did u do a leakdown? Pickup gap correcct? Quote Link to comment Share on other sites More sharing options...
evorulz Posted November 11, 2011 Author Report Share Posted November 11, 2011 Yes it still has the tors conneted and i will try disconnecting them also the bike is really hard to start and some times it wont start and has to be push stated, but if you hold the throttle open and pore some fuel down the carbys it will start, i have checked commpresion and spark both are good and it has new spark plugs when you ride it around it feels normal than one side will backfire anfter about 30 seconds of riding and the other side cylinder will just keep running.

ginger Posted November 11, 2011 Report Share Posted November 11, 2011 i know at one point i had bad fuel or oil in the tank and it would run like shit and backfire. i would assume yours is fresh. try for shits and giggles, switching the spark plug wires from side to side and see if the problem follows.

Surfrjag Posted November 11, 2011 Report Share Posted November 11, 2011 Reclean the carb on that side and check float height maybe? Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted November 13, 2011 Report Share Posted November 13, 2011 pull the carbs out and clean them thouroughly.....i mean take the pilot and main jets out also and then clean every hole and over-flow..... also make sure that you did not put your carb slides in backwards.....they should have the half moon cut out aiming townards the air filters.... Then disconnect the TORS unit AT THE BRAIN....which is the small black box under your gas tank on the left side of the bike. Check to make sure your choke tube.....the little black tube between the carbs is in place and ON THE CORRECT NUBS ON THE CARBS.....seen them get put on the wrong ones before. then report back.

AKheathen Posted November 14, 2011 Report Share Posted November 14, 2011 also, make sure your carb bowls are on the correct carbs. there is a right and a left. the one that goes on the choke carb is drilled out and has the choke jet installed in it. you can see from the outside by looking on the side of the bowl that faces the cylinder and you will se a little brass bb in just the one bowl. it really sounds like it's just not getting fuel, and i'm assuming you choked it to start it. have you pulled the plugs and look at what they are telling you? if you do not find anything in the fuel, airleak, spark, or comression area, look at your pipes/silencers for restriction/fuel/debris, and check the reeds for cracking or gapping Quote Link to comment Share on other sites More sharing options...
evorulz Posted November 14, 2011 Author Report Share Posted November 14, 2011 found the problem i was missing a tube that goes between the two carbs and the right side was running lean it must of fel off when riding thanks for all ya help Quote Link to comment Share on other sites More sharing options...
AKheathen Posted November 14, 2011 Report Share Posted November 14, 2011 if it fell of while riding, replace it with new vacuum line. likely the reason you just did a topend. Quote Link to comment Share on other sites More sharing options...
