I tried to post this in the How-To section, but it kept saying I didnt have permission. So Im posting here.

Im thinking about doing the poor man's quick turn throttle mod for my F4i. Rather than spend over $100 and have to re-wire a new kill switch, I am opting to be cheap and do it the ghetto way.

Does anyone have experience with this, using the zip tie method, or using a round section of PVC pipe around the throttle tube? Can you give me any insight to this or reccomendations? I googled this but al I ever find is yamaha or suzuki related stuff. I want to know specifically for my Honda if there is anyone out there.

So my question is, has anyone done this quick turn throttle mod the homemade way? If so, please share your experience and knowledge and any how to if you got it. Thanks in advance.

this is the how to i've got from my r6 board. different bikes same theory:

This modification will make it so you do not have to turn the throttle as much to get the throttle all the way open. This is so that you do not have to reposition your hand on the throttle to open it all the way. It is very useful to those who ride on the track.

A little warning about this modification.
This WILL make the throttle more sensitive. You will not have to open it as much to get the same amount of power as the stock throttle.

Things you need:
PVC pipe - 1 1/4 in
Dremel
Throttle off of your bike or a new one
Some type of glue (I used Loctite Super Glue)
Some sandpaper

This was done on a 2004 R6.

The unmodified stock throttle should open this much to get WOT.This modification will make it so you do not have to turn the throttle as much to get the throttle all the way open.

First, go to any hardware store that sells PVC pipe and have them cut you a small piece of 1 1/4in pipe.

http://img.photobucket.com/albums/v237/johndr83/forums/3.jpg

Remove your throttle from your bike. When doing the rest of this modification, I found it easier to detach the brake lever and right side ram air cover so they don't get in the way.
Now put the PVC pipe up against the throttle and mark where you want to cut it.

http://img.photobucket.com/albums/v237/johndr83/forums/4.jpg

Cut the piece of pipe where you marked it at and slide it on the throttle tube.

http://img.photobucket.com/albums/v237/johndr83/forums/5.jpg

Cut it some more if you have to to make sure the piece of pipe seats properly around the tube.

Now take it off the throttle, and using the dremel, round off the edges of the piece pipe. It should end up looking something like this.

http://img.photobucket.com/albums/v237/johndr83/forums/6.jpg

Use some glue and glue it onto the pipe. You can use some sand paper to smooth it out if you want to.
--Make sure that the PVC pipe is not wider then the part of the tube you are glueing it to. If it is then it will rub against the housing and prevent the throttle from snapping back.--

Take the throttle housing off the clip on and remove the throttle lines from the housing. You're going to have to grind down the metal throttle line tubes so that they don't rub against the PVC. You will also need to grind down some parts inside the throttle housing itself. I've circled the parts that I grinded down using a dremel. (sorry that it is a little blurry)

http://img.photobucket.com/albums/v237/johndr83/forums/7.jpg

Now you will have to loosen the throttle cable as much as possible. Here is the page from the service manual that explains how to do it.

http://img.photobucket.com/albums/v237/johndr83/forums/8.jpg

Once it is loosened, you can now put the throttle back in.
Once you have it in, play around with it making sure that it is not rubbing anywhere. Turn the handle bars all the way to the left and right. When the handles bars are all the way to either side, rotate the throttle and let it go. It should snap back to its closed position. If it doesn't, then you may have to grind down some more parts because something is rubbing somewhere.

This is how much your throttle should turn when you are complete with this project.

and thats it.

i personally have not done it and don't really recommend it unless you are track only. it will be VERY touchy obviously.

as for specifics: the idea is exactly the same, a throttle tube is a throttle tube that does not vary from bike to bike.

For Suzukis we just buy a R6 throttle tube and put it on.. Reminds me I need to do that for my race bike. It is not a need faster accleration, but more comfort when running WOT.

Thanks guys, My f4i has such a long throw that it makes it annoying at times when I want to go WOT. but a little extra umph would be nice too. Getting used to the new throttle makes it feel like a new bike all over again lol

Yeah the 600 I never had a issue with it, as just a little extra finger roll and I was there, but holding on with your fingers on a 1k WOT sucks and I can't get used to wrapping my hand around the throttle.

R1 throttle tube (05-06 for sure as memory serves) is better on a 1000 vs. the 1/8th turn of the R6... Just some 411...

The R1 is more between 1/4 turn (OEM) and the 18th turn of the R6...1/8th on a 1000 is retarded quick.

personal opinion is.... NEVER,,,NEVER put a ziptie, pipe, or any other foreign object on your throttle tube. If it sticks, or comes loose, YOURE DEAD... spend some money and save a life. It could be yours.

Best advice here today. If you are wanting to put something foreign in your throttle tube and fuck with the cables and such in a manner like this, let the riders around you know so they all ride behind you in case shit jams in there....:eek:

1/4 is what you have stock on the bike now. It's what they come with from the factory.

1/8th is R6.

3/16th is R1 and what you want...

Not sure why you are confused with the 1/4 turn throttle? 1/4 is usually stock for most bikes. Only a few come stock with 1/8th or 3/16th turn...

Sorter throw for street? Probably a waste. But, it does help if you have bigger hands and have to reposition every time you twist the throttle...

Brandon I used an 04 R1 on my 03 600 and your 750s are the same as that model year 600 so it will work.

Quit saying 3/16.. That is actually more rotation to get WOT then 1/4 which is stock..

4/16th (1/4) is stock. closed|----|open

Smaller distance of pull is 3/16th. closed|---|open

Smaller yet is 2/16th (1/8th). closed|--|open

Where are you confused?

Just go to a shop and spend $14 on the year like Chris stated (I'm not 100% on what year is right for your year, but I think Chris is dead on) and you'll get a new throttle tube with grip. Otherwise, you'll probably spend the same and have to pay shipping on top...

No issue with cables - it is a plug and play sort of deal. Take your throttle tube off and replace. Ride.

I'd do an 1/8th turn on a 750 in that year... Maybe get one of each and see what you like.

Yeah, check out Ron Ayers at www.ronayers.com (http://www.ronayers.com) and look up that year and model and you'll see the price at retail. Plus, you'll have the OEM part number, can call the shop and tell them to order that part and know it is right.

ive got a 1/4 turn and love it. for both the street and when i took it to the track. annoying haing to reposition ur hand when the time comes. on the trumpie i can use either a r1 tube or the triumph spirnt (i think thats the right model) i went with the triumph model one just to make sure there wouldnt be possible sticking issues...

STT-Brian

01-25-2009, 11:04 AM

this is a really nice and cheap mod i did this using 2 zip ties some puddy, small screws from HD and a unibit. the thickness of the zip ties and number of zip ties you use will determine the lobe diameter.

here is a pic for those interested.

Again, for like $10-$12 at a Yamaha dealer, you can turn your GSXR 1/4 throttle tube into an 1/8 or 3/16 and not have zip tyes and screws and putty in your throttle housing...

Might be cool for the street kids, but any of you track day guys (where this mod even makes sense) doing the home made version, send me your throttle tube and I will make you one. Send me $12 and I'll toss your stock one over my shoulder and buy one from the Yamaha dealer... I'll include a free grip as well!;)

The problem with the yami is the size of the tube is not the same as oem for one and two you are restricted to 1/5 & 1/6 tubes.

If your happy with the yami tube enjoy, i spend about $0.80 for my screws and a little bit of my time and some ingenuity to do the same thing and can always change it to say 1/7th or go back to stock.

sorry man but that just screams cable wear to me. at the end of the plastic thcable is making a hard angle across a hard surface and if it would wear into the plastic it would eventually get in touching the screw head. maybe not tho??

Actually, the R6 tube is 1/8th - not recommended for a liter bike and the R1 is the in between which is 3/16ths. A lot of racers use these tubes and they work fine. Trust me...

But, what do I know, right?:rolleyes:

STT-Brian

01-25-2009, 03:20 PM

Actually the cable does not make contact there and the picture is not the last one i took that day which shows the end of the top zip tie tapered off so there is no contact at all between the cable and the end... Like i said if you want to use the r1/r6 knock yourself out. I have done this bike to all my bikes and 40,000 miles on my last bike no issues

cheer

It would make contact as the cable comes from the inside area outwards.

40,000 miles is cool, but it only takes one time and it isn't too cool... Track day guys like Adam aren't going to want to do this mod at all. Stick with a throttle tube kit that you can buy...

As far as what I was saying, again - it is for GSXRs. Not sure what the other guys do...

Again it does not make contact, until you do this mod as i have done and racked up the miles I have then its a matter of your opinion and nothing to back it up. I have proved 40k miles and not a single problem.

Where are reputal guys saying they are that ratio? 3/16 is pretty close to 1/5 so they may have vague info. 1/6 I think is older stuff...

Where was this stated? Let me guess - the vast knowledge base found on gixxer.com?

01-25-2009, 04:07 PM

Well like i said im not a Yami guy so you are probably correct here the 1/5 & 1/6 is pretty much most forums from r1-forum r6-forum gixxer.com hayabusa.org 1000rr.net and a few others. i suspect its easer to say 1/5 then 3/16 but you seem pretty knowledgeable about the Yami so well call it 1/8th and 3/16th for arguments sake

Of all the research I have done, it seems like for a Honda, if you dont want to spend big bucks on an HRC or other aftermarket racing kit, the only thing to do is modify the stock throttle tube, either with zip ties or pvc pipe. I wish the Hondas could be a direct swap like the Yamaha/Suzuki
