Throttle can be like an "ON-OFF" switch compared to a four stroke. You need to preempt the response to stay in front of it going turbo... I'm guessing you have learned to subliminally dance with your trigger finger Andy. Lowering compression is usually accompanied by a lower fuel efficiency (all things being equal) but I am guessing the typical cruse RPM with the XC head must somehow be inside the pump resonance... I cant see how, I guess a lower pressure shockwave travels slower giving the bottom end a better breathing timing I'm shit with two strokes! This is assuming the exhaust and intake remain the same and just the head is swapped out? Quote Link to comment Share on other sites More sharing options...
AndyB Posted October 13, 2020 Share Posted October 13, 2020 My main issue is that I switch every few months between Nitro and Tornado. I had to learn to be careful! Quote Link to comment Share on other sites More sharing options...

I'm guessing I would find the response a bit wild having flown a four stroke for so long but I'm thinking I would be enjoying the extra 20kg of thrust too much to let the throttle get on my tits 1 Quote Link to comment Share on other sites More sharing options...
