I sent this in last time the 6 speed question came up - might be worth trawling the
archives, too.
"Quote from Pete Beale (UK Yamaha tuning "Guru") in Performance Bikes magazine April
1997 "top tip for Thunderace owners: the five speed box is crap - it keeps jumping
out of second and third. The YZF750SP gearbox uses four dogs per gear - same as an
OW01 - and fits straight in. It's loads stronger"
Which leaves three areas of doubt:
1) Is the Thunderace box the same as the GTS?
2) Is a race engine builder's concept of "fits straight in" the same as yours? Does
he mean "fits straight in when you've already split the crankcases??
3) Why d'you want to do it anyway? Has your GTS ever jumped out of gear (he probably
means "jumps out of gear when trying to do clutchless changes on the racetrack")? "
