Just wondering if anyone knows whats causing this,basically after installing the big bore kit i've noticed that the bike still starts first press of the button and sounds great but sometimes when i give it some throttle it cuts out and i need to restart the bike and other times its fine and runs very nice but when i de accelerate the exhaust pops! i havent changed my jetting so could that be the problem since its a bigger piston and bore not enough fuel getting to it?i'am still running the same stock pilot jet but my main jet is upgraded but not sure what size it came with the DEP S3 exhaust.
