    "Playing" with the Fuzz?

    Fooey. I did it for years, and on a lot less competent equipment. No matter how good you are, eventually it will catch up with you. Looking back, I'd say it was more likely that I'd be shot or beaten to death by the cops than sent to jail.

    79XL500 High comp. pistons?

    (Long ago) I ran an Arias piston in mine, and it was spectacular. My experience with Wiseco pistons in H-D Sportsters (I refer to them because of the bore size and air cooling) is that to run them hard, you have to give them about .001" clearance per inch of bore-we ran about .004-.0045 clearance in the XL1200 big bore 883 kits, which used Wiseco pistons. The same 883/1200 conversion with JE pistons required only .0025" clearance. Also, what oil are you using? A high-quality full synthetic like Amsoil, Royal Purple, Motul, etc. will prevent piston scuffing much better than standard oils. Don't cheap out.

    XT600 CAM Timing help....

    Stick something clean and relatively soft (like a plastic rod) down the spark plug hole, and rotate the motor slowly while feeling for the piston. You'll be able to tell very closely where TDC is; then you can see if that mark is correct. The 'right' way to do this is with a degree wheel and stop device, but fingering your plug can be close enough if you're not trying to find the last 2* on your race cam intake closing. P.S. If you feel the engine stop while a valve is opening, stop and find out why. You may have to set the cam to the firing cycle and unbolt the sprocket while you find TDC.

    1974 xl 350????

    I've been checking eBay for singles, and XL350s in running shape are bringing $750-$1500. I'd say it's a steal.

    82' xl500r honda

    It can only be a couple of places. Valve seals; doesn't sound likely, based on the volume of oil used, and rarely will exhaust valves pull wet oil in. Head gasket/oring; doesn't sound likely, the oil has no direct path to the exhaust port and if that much went through the cylinder, your plugs would foul. Secondarily, the cylinder seal would have to be compromised and would more likely blow out rather than suck. Valve spring seats; My bet. If the head has been ported or had valve spring work, you may have a hole between the exhaust valve spring pockets and the exhaust port. I've seen this before, in many different engines. It fits the profile, and may occur even if nobody's removed any material if a crack has developed.

    When did you start riding and on what?

    1976, at 15 on a 1968 H-D Sprint 350. It was incredibly heavy (for a 110lb weakling) and had such an impossibly heavy clutch that it broke 3 cables in the year or so it ran for me. The only reason I could pull the clutch was because I had to milk about a half-dozen goats twice a day! At least nobody could ride off on it. It had some great sprocket out back which also made it nearly impossible to stall after the clutch cable broke. (no kill switch, either) Wish I had that ba*tard back now. I keep thinking of a custom-framed roadracer built around one...
