Foul'd plug help

[xJust_Causex]

on NGK plugs, the lower the number the hotter the plug,( I always thought the 9 was hotter as well till I found NGKs guide.) and if its 90 up there and if all yo have is airbox lid removed and it chopped good, then you are covering an air leak, perhaps when you changed reeds?

EDIT:

So I did some reading, and yes the lower the number the hotter the plug, but what it means is that it transfers more heat from the combustion chamber. So in actuality its colder, and the colder plug transfers less heat, keeping the heat in the combustion chamber, making it run hotter. We where both right begin with, and I should have read into it more before I changed what I knew, haha.

Try running 40:1 because the more oil you run the leaner it burns, and that could be your problem running 32:1 may be too rich.

When I pulled the br9es plug out that i put in yesterday that maybe had no more than an hour on it.. it was black again but was still running fine.

drained the tank, new fuel filter, drained and cleaned the carb. 32:1 klotz super techniplate. new br8es plug. Fired her up and drove around like i did yesterday on the new br9es plug and she runs great. I'm going to pull the plug once she cools down and see what were working with. I'm hoping it is not black... lol

Alright... heres what I got, and the best pic I can get although I wish it would have been better.

Top is a tanish color
The insulator has like light grey coating near the top
The bottom of the plug is black (no ash) and the inside of the plug is clean except for one spot where there was some black.
In the bottom there seems to be a touch of orange.

Oh, and the plug is dry.

I just dropped the main to 350 and seems to run a bit better in the mid range.

haha never thought about it that way, totally makes sense. And i honestly don't think the reeds have been off, i am the third owner, and the first two barely rode it yet even looked at the engine. I can show you the DYNOJET instructions if i must that call for a DXP 350, for a bike with a k&n filter and no lid and stock exhaust. so imo its good, i'l be proven otherwise if it blows, i do plan on purchasing/making a compression tester, at least before i mess with the reeds.

And desgre90, do an actual plug chop to see, look through the search for the thread if u don't know how, then post pics so we can let you know
