So had some time on my hands and decided to get some parts cleaned up with Isotropic Finishing and they came up a treat I think. Had the gears back cut before cleaning so it should be an altogether nicer shift now.

I have had a love / hate affair with clutches since I first go a ZX14. I have a Rock of sorts, Hays Super Slider and OEM with MTC lock up. There has always been a thought that you need to back date the transmission input shaft to get a better clutch. Tim Hays has resolved that with clutches that fit the Gen 2. However I want all the options so I set about modifying the Gen 2 shaft and Gen 2 inner hub and now I can fit either Gen 1 or Gen 2 clutches at will.

That OEM gen 2 hub is hard I went through 2 ceramic tip on the lathe and you can still see the vibration marks. I should never have to remove the transmission again or consider setting up for a gen 1 or gen 2 clutch.

Next up is setting up Tim's super slider as a ride back clutch. Not as simple as it first seemed to be as there are all sorts of tolerances and run outs to take into account.

The top shaft is the modified gen 2 shaft and goes with the modified inner hub, The shaft is slightly longer than a gen 1 but shorter than a gen2

about 1 hour on the lathe for the shaft and hub mod and about 2 days in the tub for the polish. Back cutting of the gears is about 4 hours work but I had to send it out and took 4 weeks.

The problem with having a good look at it all is you have to put the dam thing back together.

Man my buddy has been doing trans with the Isotrophic coating for a few years now. It really is amazing at how much more freely everything spins. I haven't ever had it but it definitely looks like it would help save parts! :bigthumb:

Nice parts, looks like they are going to fit with ease.

That's a great polish job. They look like brand new. What did you use to polish them with, OzzyMax?

it's Isotropic Finishing, basically a rumble tub with ceramic beads and a solution. I see a few firms are starting to advertise their parts finished like this.

Cool, Ozzy. I wish I had the time and money to do so many things with my bikes. Maybe someday. Thanks for sharing this.

If you have access to or own the equipment to do this sort of thing and the knowhow. ...not to mention disassembling an engine. I'd love to do all kinds of this stuff but I think I will be an old man if I ever get to that point...or a slightly younger poor man. There's too many cool things to do and my bike is 10 years old already.

Here's what I mean, Oz. My idea of a cool mod is this lightweight mudflap bracket I made. Reduces weight by 50 g.

When I see pics of turbo builds and engine builds, I just have this feeling I will never get that far but I wish i could. There's a guy on hayabusa.org Making his own 5 cylinder engine. He has already made the frame. I mean this guy is actually making most the motorcycle from total scratch. He's not buying the parts and assembling them, he is making the parts. I feel pretty insignificant and I've been at this 10 years. Much respect to those of you who take this to the highest level.

there are some very clever people about doing all sorts of things. The more equipment and machines you have access to the more ideas you come up with. Some fail some work ok and occasionally they are fantastic.

Think it up, if it's with in or maybe just outside your limits have a go. Whats the worst that can happen? you just back where you started.

Any thing you can do for yourself usually is worth ten fold the cost savings in personal satisfaction. You have done heaps of stuff to your bike and should give yourself a pat on the back for having a go rather than just paying a shop to do it.

Thanks, Ozzy. Yup, you are right. There's not a lot of people who mess with their 14's a whole lot anymore. Not like 10 years ago. When it comes to average Joe Schmo with a 14, mine's exceptionally unique. Who knows how long I'll be at this? I might end up being a seasoned pro in another 10 years.
