Love my M1 TR w/850's. Throttle response is instantaneous.
My setup is not "practical", it is obnoxious and I love it.
Haven't got the milage thing worked out yet but I am getting there, need an LM1.
Works great on the street, cruise around at 2500rpm, stab the throttle and it goes to 4500 instantly and all heck breaks loose.
Works great puttin around the farm also lol.
Try it, you will like it!
