Hello!
I took my 1985 kdx200 into the mountains this spring and it idled poorly and had no low end power above 6000ft. I know this is a low speed jet issue, the problem is that the 1983-1985 KDX200 carbs (Mikuni VM32) have no pilot air screw, just a pilot jet. Question, how do you adjust the low speed mixture on these bikes? I suppose I could just try a variety of pilot jets, but there has to be a more efficient way to get the low speed mixture right.

Thanks!
