How To: R6 Graves Quick Action Throttle Install
Graves Quick Action Throttle R6 Install..how to guide.
I just installed the Graves quick action throttle today and with no how-to guides available, i thought i would post up what i did.
I also changed my throttle cables over with a brand new OEM to make the feel and response of the throttle like new!
Here are the steps:
1- remove handle bar end.
2- using an air gun, blow air in between your throttle and grip to remove your grip easily.
3- Now you can remove the allen bolts on the throttle housing and remove the top and bottom housing. Remove both push and pull throttle cables and then remove your throttle from the bar.
4- Inside the top throttle housing are two throttle stops. Carefully grind these off with a Dremel. Be sure not to grind too far into the alloy as it is thin. I used a dremel with a fine grinding head for this and put the housing in a bench vice to hold it absolutely still. Run some fine sand-paper over the surface when your done just to be sure.
5- Mount the Graves throttle inside the top and bottom housing and clamp together and rotate the throttle to ensure that it rotates freely. If it doesn't, chances are it is catching on the throttle stops, so you must ensure you grind these completely away..
6- Use a good quality Silicone Lubricant to lube your handle bar where the throttle mounts and mount the Graves throttle. Connect the bottom cable to the Graves throttle first and the bottom housing, matching the pin on the housing with the hole in the bar for correct alignment.
7- loosen the top throttle cable adjuster nut with two 8mm spanners, by turning the nut clockwise. Remember approx how many turns you loosen the nut so you can get a ball park adjustment when you refit the top cable.
8- Connect the top cable to the Graves throttle and close the top housing onto the bottom housing, making sure that the cable guides BOTH line up inside their respective ends of the throttle housings.
9- Refit the allen bolts and do them up finger tight for now.
10- Double check your cabling making sure that both cables follow a natural path to the throttle and the rubber dust cover can now be re-mounted over the top and bottom throttle housings.
11- Check the throttle for correct operation. Full throttle is about a 1/4 turn and it should snap back fast if everything is aligned and if the throttle tube is lubed well on the handle bar.
12- Re-tighten the throttle adjuster nut by turning it anti-clockwise. Start with the same amount of turns and check for free-play. There should be around 3mm of play either side of the throttle at idle. Play with the adjuster nut until it feels right.
13- refit the handlebar end.
14- Your done.
I love this progressive throttle. A lot of people on the R6 forum complained about the price, etc...
The face is that this is a very well designed, great quality part. The bike is super responsive especially in the low - mid range and the top end comes on very strong and quick when you get into the higher revs.
An awesome improvement over stock!!!
