Dear experts, I have to take out the gearbox, it seems. The question is: if I take the engine out of the frame, is it possible to remove the lower half of the engine, and take out the gears WITHOUT removing the cylinders, pistons, cyl.head etc.? Thank you in advance.
Disassembled the engine, removed the gears. TBH the gear dogs didn't seem too terrible, but if it jumps out of gear what can I do...I was lucky to find a low mileage gearbox from a '94 FZR600R, and combined the best gears into a working unit. The 2nd gear pinion is a b**** to remove and install... Now I wait for some Loctite sealant, then I'll reassemble the engine.Just for my own entertainement, added the costs of necessary parts together, if everything was new. Wow. Good thing that almost everything's available new, but a complete transmission overhaul, some crankshaft bearings, a complete gasket set adds up to the value of my bike, even if every work is done by me.
Thanks. FYI I didn't use the FZR600 transmission, but the '94-95 FZR600R, which is identical to FZS600 and YZF600R Thundercat
I cheched all the parts, the shift forks look good, measured to be square, no bend. Shift drum is like new, the bike has 36 000 kms in it. Clutch is ok.Some gear dogs were rounded off unfortunately, but I was able to replace them with donor parts.
