I went to do another plug chop yesterday, and the engine would just stutter and bog out so bad that I couldn't even get out of fourth gear, when my neighbour, a long time sled head wandered over to take a look. He suggested to pull out the choke when it was running at its best to see what happens, and the engine would totally die, then he suggested taking off the air box lid since I didn't have any other jets on hand to try. The machine really smartened up, and he said that that is how a 2 stroke is supposed to run. I only did one pull through the gears that way as I didn't have another plug to do two runs on, so the lid went back on to get home.
As mention before, my leak test showed no leaks, compression at 130, everything is completely stock except for a uni filter, and a new genuine Mikuni #230 jet, with the old #230 it ran better. Float level has been rechecked for adjustment, and it is within spec.
It just seems odd for the engine to be happy with a stock #230 and open air box with a uni on it, I think I'll go do one more chop with the lid off, but that just feels all kinds of wrong in my gut, but the quad seems happy.
Doesn't the old saying go "Your 2 stroke runs the best just before it dies!"
