1998 Valkyrie - White smoke from Right Exhaust on Takeoff and Accleration

[dbdoucet]

Hi Guys, I recently purchased a 1998 Valkyrie Tourer with 2,400 original miles.   It had been setting up since 2020 due to previous owner passing and delay in wife trying to sell.  I recently had all 6 carburetors cleaned and synched - also recently installed a new cockpit valve.  I am noticing that when I have the bike idling and twist the throttle, I am getting a significant white smoke, just from the right side exhaust - also see some fouling on the spark plugs on the right side.  Any ideas on what could be causing this?  I've ridden the bike over 300 miles and when I am at speed, I don't see any exhaust at all.  In other words, I don't think it's a blown head gasket because it isn't showing the white smoke all the time - either that or at higher speeds it dissipates and I can't see it.  Appreciate any advice on how to troubleshoot the problem.  thanks in advance for your input

Here are easy things to check that might find the (basic) cause of the smoke.

1. Make sure that the oil was not overfilled.  The full mark with the bike upright means 3.9 quarts went in there.  

2. Does the oil look clean?  If it looks like chocolate milk, coolant is leaking into the oil.  

3. Is the level of coolant in the plastic tank full and not going down?  If that level goes down it is a sign of an internal leak.  

4. Remove fuel hose from carb bank, open petcock and drain perhaps 8 ounces into a glass jar.  If there is water in the gas it can screw a lot of things up.  If in doubt, remove the tank and replace the gasoline.

5. Was there smoke visible before the carb service?  It is possible the service action screwed up the fuel mixture.

6.  And does that smoke prodice an odor?  Sweet = Coolant leak, Gas odor = Mixture, and Burning oil smells like burning oil.

If these actions don't find the basic cause you may want to have a professional mechanic look at it.

There is a procedure in the manual for differentiating between oil getting past the rings, or getting past a valve stem seal. The latter is probably more common. I had to change the ones on the right head once. I figured out how to do it without pulling the head. If it turns out to be a seal, hit me up and I will explain and loan you some tools you need.

Just a thought, drain hose from air box empty? If it fills up it could be pulling the oil from the air box.
