Throttle cable setup for Tr1ke

[vtR1k]

I discarded the original throttle because I found it very poor and found on Ebay a universal throttle pedal.
It's adjustable in every possible way and feels very good. For the pull-system I made something with a spring and the original cable. If I don't forget it, I will make a few pics of it.

Thanks for the help. I wasn't sure how to convert the push/pull type to a pedal system. When you can post some pics please do....every little bit helps.

I used a modified cable made by Venhill onto the original carb linkage, and then used a return spring on the throttle pedal end, seems fine.

We've got a 2005 R1 which is a fuelie so this should make it a bit more interesting. I've posted a few questions on this but I was hoping to see some pics of some kits that were using fuel injected motors. Hopefully it's not going to be too much of a hassle. Thanks for your help..........

The pull-pull is a safety linkage. If the cable gets stuck for whatever reason you will be able to force the throttle down if needed. I would not be sure if a single cable would be my preference.
I have been flying Rc planes for over 22yrs and a pull-pull linkage has proven to be very strong and low friction.

I use a push-pull system for the throttle for safety reasons. Of course, I use a throttle pedal with the usual springs. Found it on ebay. Because the pedal is a "2-stage"model, it feels very natural. Also, its very easy to adjust it just the way you want. But for pulling the cable back, I made an aluminium tube, with a little sping inside. This spring I connected to the original pull-cable. This is a little video of what I did:

Hi Rik,
Your modification looks very nice but I still have doubts if it works properly in worst case scenario.

I have had several carb failures on my Ducati 750sport and TT2 (Mikuni and Dellorto) both pull/spring operated. Problem is with cold weather the valve gets jammed due to icing and I had to use the cut off switch to save me from a 6000rpm running engine while driving in traffic.
with the R1 engine not placed in the frame+ tank the carbs do not use warmth coming from the engine and this may cause icing on early morning road trips...

This may be a good reason to convert your parking standard switch to a killswitch close to the gear shifter. It's a lot more faster to actuate instead of thinking"hey! do I need to turn the key switch to kill that engine but that may be scary because it's dark outside and i may not be noticed by other cars(!!)" . And one could connect all indicators to this switch as well.

regards,
Erik

Well, there are two springs to pull the pedal back, 2 springs on the throttle bodies to close the valves, and 1 auxiliary spring to pull the pull-cable. I think this will be enough. I never experienced any carb freezing on my Honda VTR1000, which also has Mikuni's. I also adapted the kill switch in the trike, with a flip cover...
