DIY engine tuning....
my sisters ex and I decided we were going to have a go at the bmf moped race. We new the theory re two stroke tuning, widen the ports to get fuel in exhaust out so when we picked up this old ar50 we new we could make it quicker, and we did. While I was at work,Gavin hit the ports with a grinder, well you could have put your fist in the slightly modified holes, who needs Stan Stevens.... We popped the barrel back on and kicked it over.... Nothing, well we had fuel and a spark so it must need a push, I think we hit 10-15mph before it fired, and we got it up to about 45 so we were happy with the top speed, only problem was it didn't have enough torque to pull away, hmm maybe there's more to this tuning than meets the eye

Complete fabrication, I didn't make it up!
