Quick Turn Throttle Project

[milehigh]

After searching for a while for a quick turn throttle kit, with no luck, I decided to make my own.

I sourced the racing throttle from Yoyodyne. The throttle comes with 3 different cams. Right now I am using the largest. The kit does not come with a starter switch, so I bought a right hand switch assembly for an RC51 and rewired it to fit the Buell connector.

Because the kit is not actually made for the Buell, I had a local shop make the pull cable to my specifications.

The results:

-Insane but still fairly easy to control
-Dramatically reduced wrist fatigue

So sorry for my lack of knowledge of a quick turn throttle but what does it do exactly? Does it make throttle movement easier or does it make it snapper? Like if i move my wrist 1/4'' on my regular setup, this setup will move the throttle open as if i moved my wrist a 1/2''?

Well Done!
Plan on making a return cable?

Now that's thinking out side of the square. Very nice.

BeDaring-- a quick turn throttle reduces the amount of rotation needed to get to full throttle. In essence, it allows the rider to reach full throttle quicker.

BuellerPilot--Yes sir, I will prob measure next weekend.

TooFst-- Thanks!

Nice mod I'm definitely gonna have to look in to that[up]

Hmm. This makes me wonder... I may have to go pick up a ball bearing throttle tube sometime soon. It makes a world of difference on my dirt bike.

 

[BuellerPilot]

^^ lol I was thinking the exact same thing.. ball bearing throttle and YES makes riding my dirt bike sooo much funner!

The other option that involves much less work and only costs about $10 new it just replace with an R6 throttle tube, much quicker throttle and drops right in.

This is just what I need! I was in a accident (not my fault) on my Busa years back, and now I cant rotate my wrist all the way due to a plate and 6 screws... So in order to get full throttle, I have to "choke up" on the throttle in an awkward position. It kind of gives my intentions away at stop lights... Glade21, I think I'm getting a R6 throttle tube. What year do I need?

 

[Glade21]

This is what you want sir.

Just put this in your ebay search.

[Knuckles]

Thanks Glade, So it's just a drop in, no mods for fitment?

 

[Glade21]

Yeah Knuckles, like a 5 min job, then you just have to adjust the cable tension but thats cake.

Hmm.... I did that on a bike once, all I had to do was cut a half inch strip of a zip tie and glued it onto the throttle tube right under where the cable rests on it. It makes the diameter bigger and forces the cable to be pulled further. Total cost is 1 ziptie and a little bit of glue. The hardest part of the whole project is making sure you don't glue your finger to the throttle tube. It's completely adjustable too, because the amount of pull added all depends on how long the strip is that you glue under it.

Even without the quick turn part of your mod, it still looks fantastic with the new housing and control switch.

Is there anyone that can explain to me what the return cable even does, aside from look cool??? I've never been able to figure it out. With the spring tension on the throttle body, all of the tension is on the original cable 100% of the time. There's never a time in life where you're able to untwist the throttle faster than the spring that would give you reason to need that cable there. I'm kinda confused. [confused]

The return cable is there for safety. If the spring on the throttle body were to fail, then the return cable would allow you to close the throttle.

The R6 throttle, as well as the zip tie method are both good, but if you want to remove a serious amount of rotation from the throttle you won't be able to use the stock housing.

On the left is the cam I am using, and on the right is the stock throttle: clicky clicky

 

[BuellerPilot]

^^ What he said^^

Dependant on the butterfly design (angle of closed position and where the pivot point lies in the throttle plate plane) a spring-less throttle plate could be held open by the inrush of air feeding the engine. Like stated, if the throttle spring were to fail (break or come loose) you couldn't throttle back unless you had a return cable!

[upthemaiden]

Well that makes perfect sense then. I was going to say I could understand it being useful if something gunked up the cable and you had to close the throttle by twisting it back, but that's pretty much the same situation. I had always thought there was supposed to be some type of benefit to normal every day riding, but obviously that's not the point.
