Must see CX500. Never mind the dogs bollocks, what about the muts nuts!

In normal conditions we would use the mechanical (friction) brakes to decelerate.

Why don't you try to accelerate from 0-60mph (time it), then use engine braking to decelerate from 60mph-0 (time it again).

Then you would be able to prove or dispel your original theory.

Well, the gear faces are typically just as hard, IIRC< just shaped differently for accel vs decel. It has been awhile since I worked on this- this was on cages, and dealt with flipping axles for varioius reasons, in high horse high (relative) wieght cages vs bikes. There were some issues, mostly with gear noice IIRC, and some kind of problems with the pinion climbing the gear or something? But I can't imagine a NTX or say, the V65 or Honda shafties having any issues with a CX at all- the only way a CX will blow up a honda diff is if there is dynamite filling the empty engine case.
 
this is a really cool build, i'm excited to see how it turns out. I've always liked the way the cx engine looked but i've never been too crazy about the back end. The singled sided swing arm fixes that problem! and the tail & exhaust look killer.
 
I'm back from work and now have a couple of weeks of work in front of me.
Thanks to all that are watching and liking the build.
I had chance to get most of the sparying done to the frame, wheels, bits and bobs.
Started the build and hopefully will be posting each night this week of the progress.

This is what I’ve managed to get done this week.
After I got the forks in and stood back to look at the bike the engine looked crap!
So engine out, masking taped all the ports and gave it a spray.
After I sprayed it, I went down to the local nut and bolt mans shop and got a hand full of new bolts and replaced the lot with hex key bolts.
I’m on with the mud guard, tank and seat unit over the next couple of days and hopefully will have them finished for the next stage of the wiring.

I have a XJR1300 as my main scratching bike.

I know I can slow down banging down the box quicker than speeding up.(very scary!!!)

That why track/racing bikes have slipper clutch to stop locking up the back wheel.

Yes it's not the best way to slow down and yes use the front brakes.

My point is that we all slow down using the engine as a brake in normal conditions, I had a couple of shaft drives in the past and I never heard any “wining” when slowing down.

There will only be one way of finding out..........hopefully at the end of this week!

..and on the very dear subject of nuts and bollocks...how do plan on not making this a rolling nut roaster/sterilizer?

This is even a problem on production bikes with under-seat exhaust. I'm reminded of a old Discovery Channel biker-build show where Billy Lane routed exhaust under the seat and about 20 minutes into his epic journey literally set fire to his arse. He had to rip off the seat and throw it into a puddle by the roadside. hilarious.

I'm just picturing a hot July afternoon stuck in traffic.

I'd recommend Zircotec coating the pipes, and gold reflective heat shielding.

I don't watch much TV but am going to need to look this up. Also this fella lives in a place without what I think of as a hot July and he can split lanes :)

It was a Discovery channel biker build-off.

Go to 40:02 to see the seat go poof.
 
Here she is!!
Not had chance to do any wiring, I've got to go back to work for the next 5 weeks!
So not had chance to hear her running yet.

Thank you Mr Rich.
As you can see I've wraped the zhaust and on top of the heat shield I've put some matting.
I'll let you know how the bum burning goes!
 
Not going to lie, had some doubts about the look you were going for. I was wrong to doubt. This thing is really really cool looking. Job well done.
 
If your tuckus gets hot just ride faster to put it behind you. Should work.
 
Absolutely killer build. Beautiful.

But gotta ask after all that work, you didn't swap out the crap carbs for some Mikunis?
 
I don't get the big worry about excessive heat in the seat area? Ducati has been doing this for some time, works for them. My concern would be enough seat room, looks a bit short? The other worry about the gears being able to take the torque, gears are cut symmetrical I do believe, therefore forward or reverse shouldn't be a problem. Nice bike.
Cheers, 50gary

If you read some Ducati forums, you'll see many complaints about the seat heat. Since Ducati has started putting catalytic converters in line, the problem has gotten much worse. But that's at >900cc of thermal energy.
He addressed this with wrap and a heat shield, should be fine except for particularly hot day stuck in traffic. The engine does not make that much power, thus heat.

The Billy lane bike actually used the seat pan as the exhaust exit. He never was the sharpest knife in the drawer.
