Here is a little bit of the back story to the issues we are trying to fix. I talked my buddy into getting a Honda VTX 1300 and he found one that had been sitting for 5 years and only had 6,000 miles on it. Well the dummy rode it home 50 miles after his purchase before doing any type of tune up. The ride home was fine but after it sat for two days he went out to start it and after a few minutes it started smoking out the exhaust really bad. It is a white smoke.
I had him trailer it to my home and I ran a compression test to the service manual and all looked good. I then removed his Air Cleaner and Gas began to poor out of it. I got it removed and the carburetor. The float was ate up by the gas so we replaced the float, float valve, and float pin. The Carb was cleaned and all other components looked great. I checked his oil and it smelled like gas so I removed both drain plugs and the filter and gas poured out. The gas had an oil feel to it. Now if I would have checked that before the compression test I would have immediately thought bad piston rings. So I flushed his system with some oil and filled her back up. Put the rebuilt carb on and fired her up. For the first 3 minutes we thought the problem was fixed and then the smoke came pouring out again. Also, the Petcock allows gas to drip out in the "ON" and Reserve" position. It is my understanding that with a vacuum Petcock this should not be happening either. We have one on order. Could this be causing to much gas to be getting into the engine creating this smoke?
We are at a loss. We have now dove into the coolant system. Ran a thermostat test and all looked well. I have drained the whole system and will be adding to coolant tomorrow.
What else could be causing this white smoke to be pouring out of the exhaust?
Also, I am sure I need to adjust the A/F screw but want to get some other opinions first. The bike idles fine but if I blimp the throttle she bogs down and then returns back to a good idle. When I rebuilt my carb I did not run into this issue.
Please help!!
