My valve stem leakes at the base of the stem. Is there any way to seal that leak without replacing the valve stem?

Absolutely no way.

I've used the old compressed air trick many times and it works...on older car, truck and tractor engines. On your Kaw? Forget it. If it was possible, I would have done it with my Kaws but I couldn't because it wouldn't work. The problem is, nearly all older automotive and industrial engines have valve springs that protrude above the head, making them easy to access. Most bikes with dual overhead cams use bucket and shim style lifters with the valve stems and springs setting down into a recessed cylinder (what the inverted bucket fits into). Motorcycle valve springs are very strong compared to automotive springs, meaning it takes a lot of leverage to compress them. Pushing down on the keeper you need a cylindrical shaped tool with openings on both sides to allow you to remove and replace the locks. And the real problem is finding anything solid to attach the pry bar to. I have the C clamp stype valve spring compressor used to remove bike valves and it takes a strong tool to compress and hold the springs down. How many miles does your bike have on it? A couple of years ago I replaced the stem seals on my '84 Kaw with 76,000 miles when doing other work. The old seals were still soft and pliable. In fact, they were still pliable on my old '79 1000 with 112,000 miles on it, so I find it hard to believe your seals are shot. If it's the stem seals, normally you'll get oil smoking when you first start the engine, but it will clear up shortly afterward. Bad oil rings smoke worst on decelleration while bad compression rings blow a lot of oil vapors out of the crankcase vent, which any more vents into the air cleaner. Then it usually oils up the air filter. Road legal? Where do you live at? In most normal places some oil smoke isn't not enough to prevent you from getting the bike licensed. I say normal because I know there's some idiot cities and states, and idiot nations (I noticed you used pounds, I assume you're in the UK) that take that kind of stuff way too seriously. If that is a problem and were it me, when it was inspection time I'd use a straight weight 50W oil. That stuff is thick enough when cold to greatly reduce smoking. Good luck.

My friend in a emergency pulled the old stem out (part stayed in the tire) Lubricated and pushed a new stem in from the outside. He was lucky not to damage the new stem

no safe way. Just replace the stem. Why chance a blow out for a few dollar fix.

no you have to replace the stem but its very inexpensive, less than getting a flat fixed or maybe the same depending where you get it done

If you have a problem with a valve just take the plug wire off that cylinder.
