I'm only a PM away Frank.
You ask, I'll do my best to give you an answer.

As for actual conversion plans, I'm afraid there aren't any.
There is just a lot of random information rattling around in my head.  ;)

Cheers,
Brian

You've been great help in the past Bear and I truly appreciate the information.

Bear,  I hope the UK sidecar racers take your advice.  It seems that the dragrace crowd and sidecar racers are about the only ones needing this modification from what you have shared. You do meet the nicest people on a Honda.

Good luck guys in your adventure.

Well Bill, I guess it's up to you and I applying good old African/ European American ingenuity to this crossbreed engine project. Hopefully Keith can lend us his engineering/fabrication background toward sorting out a workable plan. I'm confident our Aussie friends will steer us in the right direction if we get off track but we've got to respect their intellectual rights to the actual conversion plans.
Yep,  but it can be done, kmb69 way ahead of most, him and Kenny......and Kenny is back working on his! Don't underestimate either one! 2017 is wide open! Let's rock this world,  c'mon y'all,  lol, Bill

If you seriously want specialty gearbox parts made and Brian cannot disclose his source....I can help point you in the direction of another great guy in the biz.

It's not that I necessarily need four dog gears, more of just a case of transmission envy!  ;)  ;D

Seriously, I don't think any of us need the heavier gear sets just yet. None of us are running bikes with 10" slicks, a 200 shot of nitrous or huge turbos with automatic transmissions. I mean like 1-2 or 1-2-3 auto, 4-5 kill set ups. Kenny is the only one besides Hayes running an auto. I think Larry has his problems sorted.

Anyone else drag racing is probably foot shifting or using a full kill 5 speed set up with less than 120 hp on tap powering a street tire. Realistically, we're Hardly in the parts breakage zone.

Though this thread is about gears, my behind the scenes inquiry for Bear is going to be slanted more towards hyvo crank set ups. Maybe one day i'll build a big motored bar bike and need the HD gears he speaks of so fondly.

I have to agree to that. As long as you are not quickshifting and hard launching the bike... the stock trans is plenty strong! Its anyways huge compared to nowadays.

I think my turbo bike makes quite a bit of ponys (120-150hp) and torque and I did ansolutely NOTHING to the 40 year old trans! :-)

A lot of times the shifting forks are bent because of mis-shifting and then it takes out the dogs fast.

Also from an engineering pov, backcutting stock dogs creates a sharp transition in the material which is in fact a breaking point. And the hardened layer is gone.

So for high powered street bikes... dont worry and enjoy the bike. :)
For side car racing... well thats another story haha!

When the dogs break the gear will damage the corresponding shift fork.
It feels just like a missed shift when it happens.

Missed shifts will result in rounded dogs.

And your right Ilga, it should not be an issue for most road bikes, I mentioned that earlier in the thread.

Cheers,
Brian
