I am getting a little smoke out of two of my pipes on the left side when I first start up after sitting a while. Goes away after its ran for a few minutes. Feel like I need to replace the valve seals. What kind of valve compressor works on the bike? I've never done a motorcycle head before. Was thinking about putting those nice new viton/teflon seals.  I planned on using compressed air to keep the valve up.

From resting on the side stand, you always get a bit of left side white vapor on startup.

It's even more obvious in colder weather.

It's water vapor that condenses as the pipe cools from your previous ride.

If there is too much oil, it will seep past the rings and make smoke until it burn off. Make sure you use the proper procedure when checking oil level, IOW, bike vertical, dipstick not screwed in.

Water vapor is white.  Oil smoke is usually darker (and should smell a bit).

Heavy oil smoke is usually blue, but very light oil smoke still appears white, except in direct sunlight.

Also smell. Oil, water, and anti freeze, the 3 things it could be.

Usually it's condensation from the pipes cooling.

Run it.
Highly unlikely you would ever need to add any oil between changes.

anyone who live in a cold climate knows exactly what water vapour looks like compared to oil.  I see it every day this time of year on all my vehicles.
