the 8v i got now doesnt peak at 3500, it peaks about 4800 from the graph i got. it doesnt seem to run out of steam at all im always hitting that rev limiter it just flys up there and my old one was loosing power from 5000 on wards and by 5500 i was changing gear to get some more poke. only other thing is i can wheel spin it in changes from 1st to 2nd and 2nd to 3rd and if its wet from 3rd to 4th. now if only it had some longer gears it be perfect but i guess ill loose that 8v pull then :S
