hey ya'll, looked through threads and can't seem to find an answer to my problem.
i have a 76 with bs38s, purchased with stock jetting. (122.5 mains) which i believe is the most lean they came. put some uni's on, and aftermarket exhaust. went up 1 size on the pilot and runs pretty good, no backfiring or anything, but feels somewhat weak at the top. so, as you should i tried a size up on the main. but now my bike is popping really bad on deceleration. seems a bit backwards to me. why would a bigger main effect my low end as such? and it seems odd it would feel lean in the idle/pilot circuit when it was running well beforehand. am i missing something simple? do my screws need to be turned out more? can't seem to find a happy place with tuning her. thanks in advance.
