[QUOTE="greg brillus, post: 35447, member: 597"] Hi there again, Well the modified 4 speed has most likely had the secondary dog teeth ground off the gears to enable quicker shifts, causes a bit of extra backlash in the drive system. I have ridden several road going bikes with their gears moded in this way...doesn't seem to make too much difference to me...As for the oil pump, if it's a road bike....do away with the two start pump drive worm and go back to a single start variety. The extra oil delivery for a road engine is unnecessary, remembering that the engine has a roller bearing crank that doesn't need huge amounts of oil pumped into it, only the cams and followers need all they can get, which can be delt with by carefully setting up the components within the timing chest....to be continued....cheers...Greg.
