then cut a o ring grove in the plastic along with three allan key cap screws

Cool. Can't wait to see more.

Always curious about the 3 screws and whether they would keep a good seal. I've seen it several times before, but never really heard any follow-up. Most clear covers have a lot more screws to secure it.

I installed I kit from the U.K.
on my rd350 LC

Never leaked once in three years of riding

The key is the o ring seal behind the window

What type of o-ring are you using and how thick is the macrolon?

Do you use any type of metal collars or ring to prevent the macrolon from cracking?

Guess it doesn't take much torque to seal the o-ring.

Key to o-ring sealing is percentage of compression. For instance an o-ring w/45% compression in a .100" diameter should have a groove .055" deep. Simplified explanation. Click here for a PDF containing everything you need on o-rings. Really.....everything.

You realise that seeing the innards isn't much of a show? What with condensation and oil fog.

Totally a vanity thing. A new place for a problem, oil leak potential. Serves nothing.
It's supposed to look cool when the bike is on display.

I think the bike looks cool while it's being ridden hard.

I am too lazy to remove the dipstick

It’s nice to see if If I am mixing coolant with oil

I think that would be a bad thing :)

I love working on the Bridgeport mill and lathe

Looks more cool while being ridden hard with a clear clutch window.

Not with a full fairing. You don't even see it.
Dry clutch...that's cool, unnecessary, but cool. A bit of weight savings, less oil. Although I only run 1000cc when I race. Less drag then 1500cc.

The idea of the dry clutch is to remove the heat generated by the clutch from the engine.
Not a lot of use on a street bike, could save you from squeaking a racer.

Lol, I'm with Bare on this one. So many, do mods for the sake of mods. I don't put sugar on my cornflakes.
The RZ doesn't need a dry clutch, nor does it need a clutch case window. Building a show bike? Go for it.
Does it need any mods at all? Hell, yes. In stock form, it's a super fun bike, as proven, that is not a good bike to start on. So many, (most) have been sent down the road on one side or the other, at some point. The potential of the bike is realized when you open up the intake and exhaust tracks to let it breathe.
I'm a huge fan of making the bike run as it should. The engineers did a superb job in designing this relic of a bike. It's cheap, easy enough to work on and provides a bang for the buck.
I have a hard time with mods like up-side-down forks, wide wheels, GP pipes to one side, but that's just me. I'm a bit of a purist. Up-side-down forks are too rigid for the design of the frame, wider wheels, unless lighter, add unsprung weight and slow down the steering, and the GP pipes take away ground clearance. I'm all about function. Form is a close 2nd.
Quite honestly, most people that try and make the bike go faster, end up scared of it. I see it with bikes all the time, cars as well. They make a major project, sink a load of money into it, and then sell it, because they "...are bored" of it. Hence, the unit is unGodly fast, difficult to ride or drive, and scares the hell out of them. Fast on the straights, is not fast in the corners.
Another peev are the big bore kits, again, maybe it's just me, but, if you want a 500, buy a 500. Going to a bigger bore may be a natural progression from worn out cylinders. It changes the characteristics of the engine. Most don't think about this, they just figure, bigger is better, faster, so they want that. For the third time, maybe it's just me, but I feel, if you make the bike faster (better), you need to get on the thing and spend hours learning to master the bike. A good rider can ride a gutless bike fast.
So...yes, I'm a huge fan of the RZ. Yes, I'm a huge fan of useful modifications. Yes, I'm a huge fan of improving riding skills and mastering a bike. Yes, I'm a huge fan of technology and improvements. I guess my point is: the RZ is a simple, steel framed platform. MODIFY ACCORDINGLY. If you want high tech, drop the engine into a high tech roller. Otherwise, be wise about what you do to an RZ...but that's just me.

jimrd, I'm a machinist, by all means keep on doing all that you love to do. I'm not crapping in your cornflakes. You are doing fun things with your bike. Jon from OZ has done some amazing RD builds and mods. My beefs are to the masses, who have very little idea about what they are doing and the consequences of their actions.
