DIY Throttle Mod

I claim no ownership of this write up or the photos included in this write up. The original posting can be found at the link following the write up. I used this write up when I modified the throttle on my 2006 GSX-R 750, and it worked wonderfully. I suspect it will work just as great on our 1700's as it did on my GSX-R, and will be knocking it out sometime this week myself before I ride to Indiana this weekend.

Enjoy

heres the supplies needed for the mod. very cheap and easy. i needed a 1" pcv pipe coupler, some epoxy, and some rough sandpaper (i got 60 grit). take apart your throttle housing (very easy, 3 bolts for the housing and an allen for the bar end, and if you cant figure this out, you shouldnt be messing with the throttle linkage to be honest)


first thing you do is cut off a piece of the pcv coupler that as wide as the white throttle cam on the handle. if its a little wider, thats fine. i used a hacksaw because at this point i been drinking for a good 4 hours, and using power tools would guarantee me to cut my hand off. besides, a hacksaw cuts thru pvc like hot knife thru butter


figure out how much of the pcv ring you need to cut out to make it fit over the throttle cam. doesnt have to be perfect, as long as you can wrap the leftover of the pcv ring over the throttle cam


cut out the piece of the pcv that you dont need, then grab a file/dremel/whatever and taper down the 2 new ends. dont have to taper them down to an edge, just get them close. by now, if you didnt see how this would work, you should


now grab your sandpaper and sand the outside of the throttle cam and inside of the pcv. its essential that this joint is glued very good, because if the pcv ring comes off, if could jam the throttle open and you could die so scuff up both glued surface real good, grab your epoxy, mix it up and glue the pcv ring to the outside of the throttle cam. make sure its lined up good with the back side of the throttle cam (youll file off the shit sticking out past the front in the next step). clean up the excess epoxy with a paper towel and let it sit for however long it says.


after its dry, grab your file and file away the pcv thats sticking out over the edge. then with your hacksaw and a thin file, cut a new groove for the throttle cable in the pcv ring. i cut mine deep enough to have just about the entire cable buried in the groove, the stock groove is pretty deep


last step is to make sure it fits in your throttle housing and doesnt bind up. theres a notch in there that stops the throttle from going all the way around, but you dont want it binding up at all anywhere else, once again, the throttle could jam open and you could die.


reassemble the throttle housing, set your throttle cable slack and your done. enjoy your snappier throttle that you dont need to regrip anymore. take it easy til you get used it it, if you crash and die because you went wide open accidentaly, power wheelied, looped and died, its not my fault.
