    I would be interested to see if there is any noticeable change if you try a stock plug.

    Actually the shovel was built from 1966 to 1985,

    FWIW I'd put the plugs in as sold with the correct gap
    and see how it runs on a couple of tanks of fuel, heck
    it might start and run better, who knows.

    I'd be worried about shortening the ignition coil life by making it harder for the spark to jump the gap. Read some info on the Corvette forum about what you are talking about, only seems to work (if at all) with the older style plugs. I had heard about indexing, but the cutting was news to me.

    indexing is good, doesn't hurt, as long as you get it setup right
    it does help flame propagation, but I doubt it will make more
    power that JB will feel unless he rides a dyno...

    I will be monitoring the gas milage for the next several fill ups. Put the new plugs in yesterday and went for a ride. Didn't notice any difference as far as performance. Bike has been running really good all summer.

    The bike has been starting on the first or second kick for months now (after 3 or 4 cleanout kicks). The new plugs have made no difference there, either. But if it gets in the low 60s or colder, the bike is harder to start first thing in the morning - the colder it is, the harder it is to start. The nature of the beast, I guess.

    The thing now is to see if milage changes. I hope it at least stays the same at 37 MPG.

    I think you'll find it's not any real difference
    that you can feel or see, negating the need to
    cut the plug tips...

    The new plugs are much better than the old stuff
    you should be able to run many years on the same plugs
    just pull, check, brush off but unless you are fouling them
    they will last for years...

    You're right but, it's fun to do and jb likes to tinker. They used to say about 8 hp in a typical V-8. indexing them makes them a little cooler and as u say, gives the spark kernel a better air /fuel charge. He if you can get 2 hp,free, why not?

    2 HP is about a 5% boost for that pan

    The motor, when brand new, was rated at around 60 at an RPM range I don't think I've ever wound it out to :rolleyes:.

    Last time I went to church (about 25 miles away) I got rained on. Today when I came out after the service, I kicked it over and stalled when I dropped the clutch - flat rear tire! I've never had a flat tire before. Looked around and found some pieces of metal laying around in the lawn and in the gutter, but I didn't have any visible punctures. Pieces of metal looked they they came from an umbrella, about 2" or 3" long, probably got chopped up under a riding mower.

    The pastor, a friend of mine and whose 10-year-old son I am teaching guitar to, drove home, borrowed a mower trailer and a bicycle hand pump and some tie downs and we got it loaded and back home into my shop. How cool is that. I bought him and his boy lunch. Great time.

    Might be a coicidence about those metal pieces I saw yesterday . . . and maybe not. I don't see how they could have punctured the tire - I only found one in the gutter and it was about 6" long. Just now I took the wheel/tire to the school shop and pumped it up to specs. Washed the dang thing with soapy water and could detect no visible leaks or punctures anywhere. Hmmm. Checked the valve stem and it seemed a bit loose. I am told that air will leak even with a cap on the stem if the valve is loose. Tightened that up. Anyway, I'm waiting to see if the tire will deflate after a few hours. I may get lucky and get a ride in today and not have to spend money I don't have getting it repaired. My fingers are crossed . . .

    Had a night last year riding with a low (flat)tire. Left home, felt a bit squirrely a times, but thought it was loose gravel or something. Met up with the guys, hit the back roads, found I had to put in more effort than normal to keep up in the turns. Unless I went quicker. Got to the point I kept slowing down to let everyone catch up every couple miles. Took a rest stop just before town limit, one of the guys noticed my front tire looked a bit off. Checked and found front tire flat, back tire low. Guess guardian angel was pushing bike up in the corners as it seemed better above 70mph on the narrow country twisty roads. In the dark. Bought two new tires shortly after. Carry a pressure gauge now. And use it once a week.

    See the faster you spin the wheel centrifugal force keeps the tire round!

    Really, true story! Well, maybe not the guardian angel bit, but it did handle better faster! Not good like normal, but better fast and flat than slow and flat.
