In the continuing saga of debugging my new-to-me 93 RMX 250 with the big bore 320 Klemm kit I wanted to throw out a question for ideas on jetting settings against what the jetting settings were when I picked up the bike when I bought it and see if you guys had any suggestions.
Main: 175 (stock is 150)
Slow: 60 (stock is same)
Air Screw: 1 turn out
Needle: #1 (top, aka most lean) position (stock is #3 of 5 total)
Idle: Screwed out to middle point (it was just a starting point, but
WTF it worked and was idling pretty well there)

Compression is 140 cold and 180 with a squirt of oil and cold. The airbox top is removed and it's got a FMF Gold pipe. It's still running the stock PJ carb.
