Trans Work Without Splitting the Cases?
It looks like I might have to wait a bit to split my cases. But I would like to replace the shift shafts, forks, and detent spring. Am I correct that these items can be replaced without splitting the cases?

Thanks Sal. I suspect it will be the same on the 14. I have to pull the oil pan and clutch basket anyway, so I hope that will give me the access I need.

I've done it both ways. Without and with spliting the cases. Not on a 14 but I'm sure it's basically the same. It is more of a pain in the ass with the motor in the frame. At least to me anyway. Are you going to take the engine out of the frame?

I wasn't planning to take the engine out. If I take it out I might as well split the cases and do the whole job, I guess?
On that note, I have another question:
I have never split the cases on a motor before. Will I end up having to remove bearing caps and then have to recheck all clearances??

I would clean eveything out with brake clean if i took it apart. the bearings should go back in the same places just fine if they look fine, and really they should. clearances wont change as long as you dont mix any up. put them in dry, with assembly lube on the side that touches the crank only.

I'm a little confused, Karl.
Are you saying to put assembly lube on the side of the bearing that doesn't face the crank?
What purpose would that serve?

Im confused too. I went with Tims advice about putting them in dry and lubing the side that touches the crank compared to the manual saying to grease the backs and lube the side that touches the crank.

grease on the back i assume is for better heat transfer to the cases, kinda like putting that goop on the back of a heat sink, on a chip in a computer
but dry is less likely to spin

Is the grease used as an anti-seize compound??
I like dumb questions, and I'm throwing them out there...

i put the rod shells in dry on the back, assembly lube on the side facing the crank.
On the mains i oil the side sitting in the cases, assembly lube the side facing the crank.

Manual says to apply molybdenum disulfide grease to the outer surface of the upper insert and the inner surface of the connecting rod big end.
Apply molybdenum disulfide oil to inner surface of upper and lower bearing inserts.
Do not apply any grease or oil to the cap inside or cap insert outside.
The molybdenum disulfide oil is the red assembly lube we are all familiar with. The Grease is different stuff!

So, I guess my question is:
What purpose is served by the oil or grease on the backside of the bearing?

Most likely better heat transfer. Never, never oil the backside of the bearings! That's just asking for them to spin.

Its easy to do in the bike, just have it up in the air, and let the oil drain for a few days........
I have changed forks with the bike in the trailer the day before a PMRA event.......LOL

So, once again, why put oil/grease on the backside of the bearing?
Obviously it is a commonly suggested practice.
I'm not here to argue the merits, I just want to know why you would do such a thing?

I guess this is just something that nearly everyone does (lubricant on the backside of main bearings), without really knowing the details of why.
I can see that this engine building thing is going to be very frustrating for me, since I like to know the how and the why.

I hear ya Shane...
sometimes you just have to listen and do as the Romans do cause the answer was never told...
by the way Suzuki's & Kawi's are very different...What works for the Suzuki doesnt work for the Kawasaki & vise versa...
Perfect example is changing the 6th gear on a Busa...Cant do it for the 14...

all my bearings have gone in dry on the backs so far... dad spun a rod bearing once but that was from the poorly designed oil pan(starvation). the motor builds i have done with a stock depth oil pan have held up very nicely so far....
