Title: R6 throttle tube install issue
Post by: bombsquad83 on November 18, 2012, 04:41:55 PM
I know others have installed the R6 throttle tube for a shorter throw, but I attempted it tonight and ran into a snag.  The part of the tube that interferes with the switch assembly to stop the tube from rotating past the zero point when the throttle is closed is not big enough.  It's very close, and it catches a little, but it's possible to rotate the tube forward past the point where it should stop.  Here's a couple pictures to illustrate.

Here's the tubes butted together with the cylinders lined up.  You can see that the OEM tube extends further out in the circled area.

Here you can see how the OEM tube interferes with the switch assembly to stop it.  This is the area where the R6 tube can slip past.

I know others have done this mod.  Did anyone run into the problem?  It's so close that it does catch sometimes.  I'm just not comfortable with it.  Are the 04+ switch assemblies different than the 89-00?  I have a '93.

can you remedy by super-gluing in a bit of sheet metal or plastic? might be the cheapest and easiest fix to extend the interfering area a little bit.

I'm pretty sure the switch assemblies did change in design when the bike was restyled.  I know the housings look different from the outside.

you have the wrong year r6 tube.

I got motion pro part number 01-0094. One of the bikes it lists is the 2003-2005 R6.  Which one did you guys get?  Weed? Graham?

I'm don't remember from which thread I got the idea for which tube to buy.  I'm wondering where I went wrong.  I know graham has an older bike and weed has a newer one.

Same on I have. But I do know the controls are different as already said

Cool.  I can sell to someone with a newer GS then.  Need to confirm which part Graham got then.

and an 02, fits in just like the old one

Post by: bombsquad83 on November 19, 2012, 05:37:49 AM
Well crap.  You guys both got the same one I got.  I didn't realize that Graham had an 02.  It must be that the switch assembly is different.  Now I have to go on the hunt for a tube with a shorter throw that will work on the older switch assemblies. 

Weed, does the SV throttle tube that you got extend out the same amount as the stock GS tube, or would I have the same issue with that one?
Title: Re: R6 throttle tube install issue

I'm not sure honestly. Can you sand it down a bit? I have nothing to compare it to being I threw the stock tube away and the R6 is installed.

You could always change controls. That's what I would do. You would have to cut the harness connector off the end of your controls and put them on the new controls but according to the electrical schematics, all the wires are the same color so it wouldn't be hard.

I *think* I have some controls out in the tool chest if you're interested

Post by: bombsquad83 on November 19, 2012, 07:58:47 AM
Sanding it down wouldn't help, it would just make the issue worse.  I actually need more plastic sticking out to stop it from rotating too far forward.  Would you mind doing some caliper measurements on the SV throttle tube that you have for sale?  I'll post a picture to illustrate the measurement that I need.
Title: Re: R6 throttle tube install issue
Post by: weedahoe on November 19, 2012, 08:16:16 AM
Sure, no problem. Just LMK what you need
Title: Re: R6 throttle tube install issue
Post by: bombsquad83 on November 19, 2012, 08:41:14 AM
I need this measurement...

(http://i265.photobucket.com/albums/ii224/dtilford/GS500/throttle_tube_1-1.jpg)

The circumference of the tube where the cable sits would be nice too, just as a comparison of how the throw will be vs. stock.  It can be measured with a string.

I saw that you have some nice pictures of the SV throttle tube 01-1045 from motion pro vs. stock.  I think it looks like that distance would be the same as stock, but I would want a measurement to confirm. 

I can get a new one from here for $11.50 here: http://www.amazon.com/Motion-Pro-Throttle-Sleeves-01-1045/dp/B002304O70/ref=sr_1_4?ie=UTF8&qid=1353340332&sr=8-4&keywords=01-1045

Would you sell yours for $10 shipped if that measurement is good?
Title: Re: R6 throttle tube install issue
Post by: weedahoe on November 19, 2012, 09:13:51 AM
Youre requested measurement is right at 13.5mm

Is this the pics youre talking about of the SV650 versus stock tube? They are different as you can see. I paid $18 shipped for that tube. I would sell it for $12 shipped. Its going to cost me $1 for the box and another 2.50 to ship it

Hey Bomb,
I'd be interested in the R6 tube, as I have an '04.  PM me details and we can go from there.

Post by: bombsquad83 on November 19, 2012, 09:46:13 AM
That is the picture I was referring to.  You paid $6.50 too much for that tube!  I'll check the measurement when I get home today.  If its good I will take it off your hands for $12 because I hate to see parts go to waste.

Anyone with an '01 or newer need an R6 tube?  I can sell the one I got for $10 shipped.

Lol. You posted before I even got done asking!  PM will be sent.

Yeah, it's new. Had it on the bike maybe a week and maybe 2 rides on it. Bought it off ebay from a vendor.
Title: Re: R6 throttle tube install issue
Post by: bombsquad83 on November 19, 2012, 07:57:48 PM
Measurement on the stock tube was also 13.6 mm.  Measurement on the R6 tube is 11.4 mm, which explains why it doesn't work.  I will buy your SV tube Weed.

Thanks again for the throttle tube Bomb.
Figured I would update this thread on the install. The R6 tube swapped right over with no problems on my '04.  Very noticeable difference on wrist position when grabbing a handful of throttle. No more repositioning the grip getting upto speed.  Highly recommended mod. Cheap and easy install that adds convenience and comfort alongside performance... and it's beneficial for both ends of the rider spectrum from touring to track.

Bumping up an old thread.

I was thinking that my GS's throttle was too long. Are there easy ways to modify the stock tube or is replacing it easy/best option?

I have a 1992. What tubes will fit?
Thanks,
Legnd
Title: Re: R6 throttle tube install issue
Post by: bombsquad83 on November 28, 2012, 11:26:54 AM
Motion pro part number 01-1045.  It's cheap on eBay or amazon.  It's an Sv650 tube. 

Basically the only difference between that and the stock tube is a larger diameter circle that the cable rolls over.  No really easy way to reliably modify the stock tube to accomplish this that I can think of.
Title: Re: R6 throttle tube install issue
Post by: BockinBboy on November 28, 2012, 11:32:06 AM
It appears that SV650 throttle tube (motion pro part number 01-1045) is currently the only known direct replacement for the 89-00.  The GS500 stock throttle tube is 1/4 turn, while the SV650 throttle tube is 1/5 turn.  Changing out the throttle tube is definately the easiest and it only costs about $10. 

If you want a more drastic change, the R6 throttle tube is a 1/6 turn... However, it only fits the newer GS models.  You would have to also change out the engine cut-off switch/starter switch housing in order to make it fit... Or somehow modify your current switch housing a little bit to make it work.

But for the cheapest and easiest fix, SV650 throttle is the way to go on your particular bike.

Bump for quick question. I just installed the R6 throttle tube but I have Zero play in the cable. The throttle closes completely but I would like a little extra play. The adjusters at the handlebars are completely in and in looks like my carb adjustment is also completely in, Am i missing something. (See picture)

Does your idle rise if you turn the handlebar all the way to the left or right? If it doesn't, I wouldn't worry about it.
Title: Re: R6 throttle tube install issue
Post by: BockinBboy on May 20, 2014, 06:19:33 AM
Mine is also tight; however, I do have maybe a mm or 1/8'' at most of play adjusted all the way out at both carb and grip.  I have raised bars, and I've never had an issue at full lock either direction.  Watched this closely for a long while after the install, but doesn't seem to be an issue... same amount of play in throttle at full lock as well.

Post by: CndnMax on May 20, 2014, 08:07:02 AM
My idle is not affected by full lock movement. I'll leave it and see how it goes, if not I could always remove the top lock nut at the carb and gain a couple mm.
