125-200cc 8 miles per plug, this is getting old...

hi dunno if this helps
having similiar problems with my wr360
it fouls/kills the plug after a hard blat
if you putt around then you can ride all day
does this sound similar?
that to me sounds like the coil is getting hot. stuffed coil?
i have had this problems with cars
mind you i havnt sorted mine out either yet
anyone know how to test a coil and what readings we should be looking for

I assume no news is bad news... Still haven't caught the gremlin? I'm curious!

It's been raining Blake, no way I can test it in the rain...

So since the last plug fouled I changed the following...

Kill switch unplugged
Changed gas cap
new ring, base gasket, reed gasket
new ignition side crank seal
tightened center case bolts (none loose)
changed premix from klotz r50 at 32:1 to torco gp7 at 32:1

I put 10 miles on it Saturday at my brothers house, in the rain... Trials tire and wet grass is no good, thanks Blake I blame you for my crash. Took it home washed it, started it up and rode it around the block, no fouled plug. Went to town, came back a couple hours later and rode it around the block, no fouled plug.

So Sunday after helping a friend put lighting equipment on his KTM200 we headed up in the hills to test his bike and mine, in the rain. I had no crashes, but I still blame Blake for all my close calls. We put in a whopping 19.1 miles, no fouled plug. Bike runs exactly the same, great! Just doesn't foul plugs!

So almost 30 miles to a plug, and it is still running this is some sort of a record!

I plan on putting some more miles on it this weekend, and may even put the other gas cap back on. Someday I will plug the kill switch back in too. I was out of Klotz anyway so it was time to use up the GP7 Bills gave me when I bought the bike. I may stick with GP7 or Kelly has been bugging me to switch to Amsoil, damn pyramid schemes get him every time...

Here is a photo my friend snapped on Sunday... I have been getting lots of crap from most of my KTM riding friends about my non running Huskys... Glad to have one running again.



Later,

Why 32:1?

From the manual...

LUBRICATION
Engine . . . . . . . . . . . . . . . . . . . . 4% (1:25) of oil-gasoline mix
during running in; NOT LESS than 3% (1:33)when running in is
over

I am sure people get away with running less oil, I stick to the MFG recommendation on this one.

Later,

After all the money and time spent changing parts why not try using a higher gas/oil ratio with a low flash point oil like Amsoil Interceptor? what can happen?

I probably shouldn't say this because it sounds so goofy, but what about coolant fouling? You have checked everything it should be so it has to be something, well, goofy.
It probably hasn't lost a drop thouigh?

I used to run GP7 myself, it's great oil. If it's readily available I'd say stick with it.

I don't believe it was your 2T oil. That residue looked like gear case oil. Glad it's working for you now.

Well I wish you luck finding the gremlin.
Did you post what your jetting is?
