It starts cold. runs for 10 seconds and fouls a plug. toss a new plug in and it runs great for the day. The next morning, same thing. starts first kick, runs good and fouls a plug... I have pulled the carb, cleaned it, replaced a pilot jet and reed valves unnecessarily and still am fighting this plug fouling. next stop Coop fuel to see if this sorts it out.
Was it the crack in your pipe? Or the fuel?Dobi wrote:I am starting to get some really weird plug fouling and am wondering if this new Shell fuel is it...

I believe I experienced the same problem last time I rode. Changed the plug fired up. Ran fine, but did cook my stator 5 km from the truck (near the end of the ride). I believe that was unrelated. I don't have co-op as an option where I am. What would be the next best? Petro can? Esso?Dobi wrote:aren't you too old to be trolling on instagram?dirtyboy wrote:Was it the crack in your pipe?

I switched out all the fuel in it last night, installed a fresh plug and it fired right up. I warmed it up in the alley and shut it down for the night. I will try it cold as soon as I get home tonight and see how it works before swapping out the pipe. I have had cracks in pipes before and never had plug fouling issues, so I am skeptical that it could be causing it. In my opinion, a new plug would foul just as fast as a day old one if the crack was the problem.

Great you got it sorted MikeDobi wrote:3 cold starts yesterday with nothing different than Shell fuel and the bike is back to normal. I even went so far as to soak the motor down with a cold hose to make sure it was truly cold and condensate could be sitting on or in the pipe. I am convinced its the shell fuel. Even though the pipe was not the issue, I took the effort to swap it out with another one I had.
Ty's SX 85 recently fouled a plug on cold start which is odd for that bike esp with 20 hours on a fresh top end and new plug. Its only happened the once, wondering if the Lucas Oil Octane booster he also runs is maybe masking the fouling issue's on cold start 
I will take it.Dobi wrote:multiple cold engine starts on Coop gas and no issues here. For what its worth I run Opti oil too.
Anybody want 5 gallons of premix....
I will leave it in ziplock freezer bags in the back of Jamie's truck after this weekend (I am attached to my gas can....)axel99 wrote:I will take it.Dobi wrote:multiple cold engine starts on Coop gas and no issues here. For what its worth I run Opti oil too.
