Hey guys a little question for the people who have a sportbike. Do you keep your engine in high rpm often (over 12 000rpm) and if so have you had any problem with your crankbearing? Beacause me and my friend are building up an engine and he already has a balanced crank forge rod and we would like the make it rev a little higher (somewhere around 14 500rpm). We know the rest of the engine can tolerate that kind of speed but we talked with someone a diablo racing and he said that on their racing bike (about 15 000rpm) the crankbearing lasts about 2 or 3 races. I know they put more stress on their bike but so do we (95% of the time at full throttle). You guys have any thoughts on this? What would you recomend as max revs? Because opening the crankcase is a pain. Thanks
