Is this to much

Is this to much? Had a maico transmission and clutch polished like the big five factory teams are doing to there team race bikes. If it helps the trans shift better and last longer I think it will be worth it.

If it does all that and should also reduce drag-so why not?

In this case function follows form! Who cares if it shifts better it looks outstanding. J

It's pretty common amongst road racers.....it does work....they change gear like a hot knife through butter.

I think your right Jerry… does look good. I heard that the shifting is great. I would hand polish all the clutch parts for a easy pull, I could never do this good by hand. I’m going to build a new motor with the cut down cases with all the polished parts and the reed top end.

You will have to put a Perspex window in the cases so you can see them!

The other day I was picking up some bling from my polisher and sitting on his bench was a Kawasaki 1000 transmission in pieces, all polished up and shiny as a new pin that he'd done for the bike shop next door to him for a historic superbike they're building for a customer. I might do a Maico trans myself and see what the difference is......

WARNING: THREAD DEVIATION.
Doug, as a separate issue, have you tried the coil spring conversion on a Maico clutch? I'm about to set up a magnum clutch for my 360 oval and want to try the Wheelsmith coil conversion I've had for yonks.

I thought that Carbon and Dry Film coatings were the go for transmission gears and bearing?

Mark... I have never used the spring but Jeff Mullins at maico werks likes the spring. I think if you have the preload set right it would work good I had all the Belleville springs polished so there is no friction, I would hand polish all the springs on some of the clutches I have done and it helps Jeff does this polishing as a service at his shop now. It is called isotropic polishing.

So do Maicos normally have a leaf sprung clutch instead of coils--that's a bit old fashioned  :D

polishing the gears and shafts will remove any surface inperfections, plus expose any small cracks or chips. also as said, oil wont cling as well to a polished surface so there'll be a smaller % HP loss due to drag.

oh, and plus it looks better too  ;) i remember seeing a clear window clutchcover kit for early GSXR's to give the bike that 'dry clutch look'...

Wouldn't say so, 2013 1/2 KTM SXF:

A special Ryan Dungey-developed 280 psi Belleville washer will come stock in the Factory Edition.

Does anyone know of a company that does Isotropic polishing here in Oz?
