Thanks. I'll be sure to check the boots, again.

If your valve guides are worn, you'll lose oil when the engine is coasting
(holding back). Have someone follow you down a long hill. Get in a high enough
gear that the bike will keep a decent speed down the hill with the throttle
closed. If it starts to smoke then (and only then), you're on the right track
when checking valve guides. New seals may fix the problem for a little while
but the permanent fix is to replace the valves and guides along with new seals.

And just for laughs, check the compression in each
cylinder. You can spend lots of time fiddling with carbs
and ignition when the real problem is one cylinder
pumping way better than the other.

If one cylinder's pumping poorly and you try to compensate
for it with tuning, you can confuse yourself pretty thoroughly
and induce some very odd behavior.
