Pat,

Went to my local auto parts store to pick up the Bosch Platinum WR7DP,
they said when they plug in the WR7DP, it comes up with an NGK plug, not
a Bosch Platinum. You sure that's the right #? He did show me a Bosch,
it was the 4 electrode style platinum, don't know how they would work.

running the typical NGK variety.

I was having terrible fuel fouling problems on a V50 Monza. Bike ran a
treat. But, if you couldn't get it to fire within about three
revolutions you were dead in the water. Had to pull and dry the plugs
before you could try again. Fought the problem a long time. It was
Regina's Monza and she threatened to divorce me or buy a Honda if I
didn't get it solved.

One day I was looking at my old V-1000 Convert. Had it about 5 years
from a previous owner. Never did anything to it. Beat it and trashed
it. Left it out in the weather. I was the most reliable starting and
running bike I have ever had. Worked under ANY conditions.

So, I pulled those old Convert plugs, inspected, and tried them in the
Monza. Bosch Platinum WR7DP. Monza never failed thereafter. No such
thing as a fuel fouled plug again. Never a failure to start unless I
was doing something else totally stupid.

I then bought the same plugs for my Eldorado. It instantly started
easier, idled smoother, and at a slightly higher rpm that I had to
adjust back down. I now run the same plugs in two EV's and an SPII as
well as the Monza.

If I have any sort of ignition problem I look at wires, carbs, etc long
before I even consider the plugs.

That enough "transformation" for you?
