HRC Throttle ???

The 03-06 600RR however does not have that room and as such requires modification. This modification needs to be done carefully and tediously with a Dremel or other grinder. Here's a pic of the OEM tube.
has anyone thrown a HRC throttle tube straight into a stock 07~08 600rr tube housing with stock cables and all without any problems?
Ive seen the mod about cutting a pvc pipe to fit over the stock tube to achieve a greater diameter, id just feel more comfortable with a HRC or motion pro tube

Yea you can buy the cables and tube. Brad at superbike supply had a deal on them a while back. It might be worth while giving him a call

It's kinda stupid to buy the whole kit unless you have a 03-06. And still a 07 throttle housing on eBay is still cheaper than the hrc. ALL YOU MEED FOR AN 07 IS THE TUBE lol

Yup,

Bought the hrc kit from Brad ($95 shipped!), I'm not complaining my oem cables are rusted and cracking (the plastic covering). Pretty sure the first owner left the poor thing outside :(

I didn't think id need the Motion Pro Revolver Kit for its four adjustments, the first two reels are closer to stock and the top two are for drag racing it seems?? (which Brad has for a lot cheaper than anywhere I've looked around, I swear Man Crush on that dude! And Mary . . .lmfao)

just after some advice guys.. How do you remove the tube from the 2 cables? I have the 2 screws removed from the throttle tube housing, but there doesnt seem to be enough slack to unhook the 2 cable ends

rotate the throttle all the way around one way with both cables fully slack and you should have more than enough there to remove one cable then the other.

thats my trouble, with the adjusters at the clipon end wound fully in, there doesnt seems to be enough slack to release the cable ends. If i turn the tube one way or another it will just tighten the opposite cable.

Unless, are you referring to the throttle pulley on the engine itself? The part underneath all the stuff i havent taken off before

If there isn't enough play at the throttle end they may have been tightened up at the throttle bodies... so yep, underneath all that stuff you haven't taken off before.

Don't stress about it mate, its nice and easy to do if a little time consuming. Once you get down into it just pop a rag into each throttle body to prevent stuff from falling in there and you will be fine.

1. The quick turn throttle enables you to move the throttle to WFO in a shorter angle than the stock tube. Stock tube full open is 90 degrees of turn; Q\quick turn, or, more accurately, 1/6 turn HRC throttle is 60 degrees to full open. It's a great mod for track day riders and racers because the throttle is easier to pin and hold.

The tradeoff is that it takes some finesse to manage minor throttle inputs. IMO there isn't much value in a 1/6 turn throttle on the street but it might be fun to have.

2. I got mine from Cru Jones off this forum.

I didnt need to get a HRC kit but my buddy gave me his yamaha R1 tube and it only cost him under $20.00. The install was easy and took less then 20 min. To me, it is a big differnce

I think I may have it. I saw somewhere someone posted a comparison picture between the '07-08 stock throttle tube vs. the HRC. Can anybody help me find it? Also, I am actually looking for the stock unit :). Around town it is WAY too finicky for my tastes and finessing it is almost impossible.

Check the FS section.

I will soon have a complete throttle tube from an '09 that I don't need. Doing a conversion on my '03 and already have an HRC throttle. I'll be posting it up in that section of the site in a couple of weeks.

nope, if it were true then turning your throttle quickly would cause the same problem...

Thanks guys, so am I correct in guessing that the TPS reads from the throttle body end of the assembly? Should the TPS only be off if the cables are adjusted incorrectly where the throttle bodies don't open or close fully?I'm no stranger to wrenching, but I've never messed with this part of my bike before, just a little skittish.

Correct, the TPS is on the throttle body. Short of physical damage the only thing that will cause it to drop calibration is for its mounting screws to come loose. The adjustment on the cables and what you do to the throttle tube has absolutely zero effect on the output of the TPS for a given throttle position.

Has anyone else used the throttle tube for a Yamaha R1/R6? There is a how-to thread on the 1000 forum. I just did this one myself a few minutes ago. It uses an OEM throttle tube that can be picked up at a local Yamaha dealer for around $20. The post on 1000rr.net gives you the Yamaha part # for the 1000 tube. The one for the 600 is the same but is black instead of white. 4C8-26240-00 is the part # for the black one. Used my stock cables and only had to use the adjustments on the housing. Just follow the how-to and you'll be good to go!! It is a 1/6 turn tube BTW. It seems to work great and is CHEAP!!

Installed mine.. Feel the diff in pick up and easily high for high rpm. I am still getting use go maintaining the trottle at certain while cruising at certain speed. It seem to be like abit hard to maintain or not so smooth as compare to stock.

Maybe is me who don't get use to it or maybe I didn't install properly...

You can get the factory r6 tube from any oem dealer. Its the same 1/6 throttle pull as the hrc tube. Google r6 throttle tube mod, you should find plenty of info on it, great improvement to our lazy 1/4 throttle pull. Easy to do as well.
