R6 Throttle Tube or Shorter Travel (rotation) Trottle for SV650, Gen 1 Race bike

[DanRo]

Hi,

I'd like to have a shorter throttle travel on my race bike. What parts do I need to do that ?

[GixerJockey]

a modern R6 throttle tube... that's it.

[Sidavong]

I should have an extra one. just need to find it in my parts bin.

[GixerJockey]

They're like $10 from any Yamaha dealer, with a new grip already installed. lol

2006+ R6. you'll need a dremmel to shave off part of the plastic inside to fit your Suzuki throttle assembly.
they were $31 at the dealership last time i checked.

Motion Pro also sells this stuff... they may be able to sell you just a 1/4 turn cam

motion pro is $150. OEM R6 is $30.
1/4 is factory on Suzuki's. he wants a shorter 1/6 cam.

If you have one, throw it in ur tool bag for LRRS #7

Thank you,

Isn't R6 1/4 too?

Cam size varies from bike to bike depending on throttle body (or carb) linkage. You could have two bikes, both 1/5th turn, with compatible tubes... but put one of those 1/5th turn throttle tube on the other bike and it could make that bike 1/8th turn.

I've run a couple of R6 tubes on my 2nd gen SV. I ended up going back to stock because the R6 tubes are too "fragile"... they don't quite fit right and the closed throttle stop doesn't catch on the outer housing very well. It can be accidentally forced past the closed throttle stop and it'll damage the cam, making it more susceptible to going past the closed throttle stop.

I had to modify both of them beyond what's outlined in the article above and even then they weren't reliable.

If I go back to the R6 tube I'll modify the outer cam housing to help prevent this, but right now I'm running the stock tube & not having any problems. (It should be noted that I've broken my wrist, reducing overall range of movement and I can still get by).

For these guys that keep saying 1/4 turn, that means 25% rotation. A 1/5 turn (05 R1) would be 20% rotation. 1/6 and 1/8 would obviously be shorter & I don't feel like doing the math right now.

[jasnmar]

The point Pete is getting at is that the "throttle" itself isn't rated in "turn" it's rated in a rate. Amount of degrees per unit length of pull. You need to figure out the entire length of pull and then select the proper rate for the amount of turn you want.

Read http://www.motionpro.com/motorcycle/...throttle_kits/ for information.

Taking a throttle off of one bike will only work the same if the total amount of pull necessary for that bike is the same.

To put it in simpler terms,
1/4 turn means 90* rotation.
1/5 turn means 72* rotation.
1/6 turn means 60* rotation.

Think the R6 tube (that ended up having the issue of going past the closed throttle stop) that I modified before ditching it was like an 1/8th turn (45* rotation). Loved it but it was like a lightswitch and NOT for everyone. Had to have very fine throttle control.

on 1st gens i dont remember having to modify mine but i could be wrong. it was so long ago. made a huge difference. i was able to to get to the stop coming out of 2 and 4 and 12 without having to regrip

Not sure if I'm going to round 7 but can make sure it goes up with someone.

PM me your contact info and I will send you pics and stuff and coordinate that way.

I have one of the 1/5 turn R6 throttles and I didnt modify it for my 2nd gen. That website is partially incorrect, 2nd Gen N and S models do have different throttle housings and cables. Not sure about the actual throttle tubes themselves.

I agree. I had a short turn setup (R6, I think) on mine when I got it. In some sort of twist of irony the throttle housing was destroyed after I high-sided in the rain. Decided to replace with stock until I figured out how to ride a gosh darned sport bike. Definitely not for those of us used to hamfisting that throttle.

I've actually grown to like the travel on the stock setup. I can get from stop to stop without changing my grip.

I lust over the adjustable motion pro setup. I'd like to go somewhere between stock and "light switch".

You may want to double check to make sure you're actually getting to WFO. It fit and worked fine on my bike without modification but would not get to 100% full throttle. Didn't I see somewhere recently that you only got 108mph or something at NYST?

I did this prior to adding flatslides and a Motion Pro setup and it definitely helped, as Oxx mentioned.

Done racing for the year , but I want to get the bike back in the shape that I wanted before the winter (shorter throttle, change the brake lines etc).

Dan

[Pigman]

I have done all the Trick ones and such and the MotionPro is still best... you can get it off RidersDiscount for 130 I think


worth all the $$$

Hmmm you are correct, I should probably confirm it will go WOT. How would I know if it is not opening all the way?
