    Puffing smoke

    The group I rode with today said my TW was puffing smoke when I was downshifting to control my downhill speed, and upshifting up hills. Is this normal or do I need valve adjustments?

    How many miles on your bike? Are you using considerable amounts of oil? Valves being out of adjustment shouldn't cause you to burn oil.. Maybe if the exhaust is excessively tight creating more crankcase pressure.

    Most likely you just overfilled it with oil. Causing an increase in crankcase pressure, pushing the oil into your airbox.

    Otherwise the most common places for oil bypass is valve stem seals (smokes at cold start) Or around the piston ring. Both will get consistently worse over time.

    Just check your oil religiously. If your burning a little bit its not the end of the world. A little extra lube wont hurt.

    Burning a little oil will carbon up the combustion chamber thereby increase the compression ration and giving you more power. A silver lining to every cloud!

    My bike is 19 miles shy of 5000. Last time the valves were adjusted was 600 miles. Runs like it did when it was new. Oil level looks fine and oil is clean, it was changed at 4300 miles, at which time they told me it was low on oil, so is apparently using some. The previous oil change was at 2200 miles. So I'm checking it way more often now, like every ride.

    Having oil changes and valve adjustments done somewhere else? Do it yourself, save some money and get piece of mind that the maintenance actually got done.

    Sounds like piston rings?

    Downshifting/engine braking regularly instead of using the brakes can wear out piston rings quicker [not implying you do this- just a thought]. Worn rings would lead to excessive oil usage, more so at higher rpm.

    Also if it was leaking from the top a valve adjustment would not solve anything, you would need to replace the valve stem seal. #6 on this picture:

    Try changing the oil again.What oil are you using??I change mine every couple hundred kms or when it starts getting hard to shift gears.It only holds a liter so the oil takes a beating and may break down quicker.

    Wow, that a lot of oil changes. I change usually after 2,500 or 3,000 miles. Have 24,000 miles on one TW and 13,000 on the other. But I must admit, I am always surprised how easy it is to shift after an oil change.

    valve adjustment has nothing to do with burning oil. worn valve seals will give a puff of blue on a cold start and worn rings will show blue the rest of the time

    I used to puff smoke a lot but I quit in 81 on my doctors advice. Puffing smoke is not good for you or your bike unless one of you is a two stroke..
    Rings and valve guides are the most serious possibilities, but check the possibility of oil in the air intake system first, possibly from breather tubes to the air intake box.
    A compression check can reveal worn rings.
