Worlds most powerful BT100 motorized bike engine

Today we're testing my new BT100 (Sold by ‪@tdrmoto‬ in Australia). With our custom expansion chamber and high flowed carb we're seeing just under 7.5HP! I'm expecting 8-9HP once our VM18 carb arrives and we get the jetting dialed in. This pipe is designed for the BT100 stock port timings and with a power peak at 7000RPM. Now that we know this motor will rev out to 10,000RPM, we'll redesign another pipe for a 9000RPM peak and see if we can crack 10HP! Not bad for a completely stock BT100 80cc motor (with boltons)
