You really notice the difference in the seat of the pants and that the 600 just almost refuses to bog, just crack the throttle and it surges forward.
Excellent, thank you for that :) Maybe if/when the XT engine fails me I'll have to source a TT600 motor for it
Updated some info; namely added ALL of the stock carburator settings and valve clearances under General Info
