let me clarify rekluse point..I can ride bike as with regular clutch 99%.
what I feel is that clutch will disengage only if you lock the rear wheel. from that moment one, it's free wheeling. but if you do not lock rear wheel, clutch stays engaged and delivers engine braking.
also, maybe it's me.. but I never felt whole lot of engine braking on my 300...
where are you located?
