From what I've seen in the manual 90 and up with no more than 30 psi difference between cylinders. Anyways he thinks it's a jetting issue and its fouling plugs and leaving gas in the cylinder. The bike had straight pipes 2 years ago and last year I swapped a 2-1 With a shaker upsweep so that could be my problem.
What I don't understand is how I was able to ride all last summer without this problem. If it was the jetting wouldn't it have happened sooner?

Thanks for your input guys!!!!

Shovels do not like long pipes , makes them a royal bitch to carberate anywhere near runnable and they are always off bad in some part of the RPM range depending on motor condition, cam & carb.
