Ive got another jetting question in regards to the new exhaust... Everything seems to be running well except when riding after I have driven WOT for more than 10 seconds. If I have it floored for a while and then left off the gas it spits and spudders and has horrible throttle response for a little while (10-15 seconds) before resuming normal performance. It has even died a couple times when going from WOT (100mph) to a dead stop. What causes this spuddering? Do I need to reduce the size of my main jets? Currently I have a dynojet 104 main in, needles on 3rd clip, screws 2.5 out, and no airbox. Thanks in advance for any advice.
