Have a 2001 Suzuki intruder VS 800. I have been riding this bike for 2 years now. Have always had a weak spark in rear cylinder. The continuous dump of unused fuel in the cylinder washed the rings out and caused oil consumption. Over time the oil burn got worse to the point the. Cylinder would no longer fire and when it did it would billow out white smoke. Two months ago I did a motor swap from a 1999 suzuki intruder. After rebuild, road bike for about a week when the FRONT cylinder started cutting on and off. Off in the lower rpms and on in the higher rpms. Not the best route but I have replaced.... wiring harness from the tank down, two new plugs, two new plug coils, new fuse box and fuses, new stator and signal generator, and replaced the the ignition box under rear seat with another used one. Still same problem. Wint hit in front cylinder in low rpms and cuts on when I throw the juice in higher rpms. When I pull front plug out, reconnect to plug boot and lay on cylinder bolt to check for spark during cranking I get shocked in the hand that is on the right handlebar control. I've crawled over this bike multiple times re checking all connections and wires for exposures. And have found nothing. It stumps me how I have the problem with the rear cylinder, do motor swap and now it's doing it to the front cylinder. I love my bike but causes me lots of stress. I obviously need help. I've checked ALL WIRES from the handlebar controls down. I k ow the cylinder is getting fuel because it comes out the pipe when it's running. Also the other day I got the bike to hit on both cylinders during idle but turned back off when taking for a test ride. Idk what else to do. This is my only form of transportation and have not been able to get to work properly for over a month. Any help is greatly appreciated. Thankyou @

SOURCE: Rear Carb leaks fuel out of the overflow tube 1995 Suzuki VS 1400 Intruder

Hole in the float. It fills with gas, sinks and fails to stop the fuel flow

SOURCE: My 98 Suzuki VL1500 has a weak spark to the rear

check your carbs. it might be dumping to much gas in that cylinder, causing the plug to fowl out and have a weak spark. make sure the carbs are adjusted and then sync them for proper fuel air mixture.

SOURCE: front cylinder dumping raw fuel, exits under exhaust pipe. Cylinder not firing.

pull the vacuum line from the regulator and turn the key on and see if gas drips or sprays out from the nipple on the regulator if so that's your problem the fuel is going threw the line into the intake port

it is probably not a weak spark. if you are determing this because the plug is sooting up and fouling and or the bike is missing or just not running right. your carbs need rebuilt. know of same problem with friends bike. tried eveything. coils igniter etc.. check out g man industries.com give them a call they will explain what is going on with your bike
