2.5L Rocket Stroker Engine Kit with 6 Speed Transmission (R&D)

[Boog]

@R-III-R Turbo Helo Arto, I just read again both this and the 2.5 kit for sale threads. Do you have any updates on the original bike you built and any new lessons learned?

Hi Boog yeah it's weird to look back to the start & breaking ground as we went along.
Pity the 6th gear side of the project never made it to production (cost too high) following the working 3D printed prototype / proof of concept.

I basically rode the 2.5L Stroker daily for the past 3 years with no issues whatsoever. It should have been this way from the factory - made me wonder why an odd size like 2.3, did Triumph originally intend to sell a 2.5 upgrade option?
Spent time dialling in the final TuneECU map to go with the kits and having fun.
Sold a couple of kits in the mean time too.

And last summer I added the Carpenter 240hp kit (minus the high comp pistons), TTS stage 2 supercharger kit, custom made low comp pistons (for the boost) and the full exhaust.
Probably the most "built" Rocket engine on the planet.
Only got to take it out for break-in a few weeks ago..

Can a Rocket III take down the establishment, and rule this island

So in southern Ireland, drag racing isn't a big thing. In fact there is only 1 motorcycle event on per year here that I know of, it's on in early April on a public road which is closed for the day. (There are no drag strips here. Only other drag races I know of are cars that do it on an airport...

...I really wish that 6 speed had come to production... would solve a lot of problems I'm going to have next year.

Been singing that tune for years. Maybe site owner will relent and allow the drawings to be posted in the resources section.

Yeap I will post up the design, 3D CAD files and all, if I'm allowed.
I suspect if the design is free, a known gear manufacturer will produce it for a reasonable price.

....makes me want to buy a gear hobber for the mill.... If the LSR R3 goes as fast as I think it will this year, I'll really have to make some sort of new gear set up, be it rear end or transmission.

I'm willing to support it as I've done for you in the past, as a new premium ad or page. Whatever you think will help get your proposal out to the masses.

One would have to register/login to actually download CAD file, but all users would be able to see the info.

Hope this helps,

Great. It would just be posting the files up as a resource, free information. I wouldn't be selling anything or looking for funding etc, just here's a design for free, go and do as you please type thing.

If I post up all the pertinent text and pics, would you be ok to attach the CAD files to it?

I will drop off a set of prints with a Gear co. west of Chicago, to get a quote....what could it hurt?

If this works out, might even have to keep the Rocket. Otherwise, will likely be on the block this year.
