After todays session I need a quick throttle, too much twist in the throttle for my liking and wrist, find myself not getting the power down quick enough due to having to re adjust my hand.

My intention is to reduce about 20% of the twist.

After a google I have found some, but they aint cheap :eek

So stand by for a DIY project :yes

There is a DIY QAT thread on RSV Zone

http://rsvzone.com/forums/showthread.php?7056-Quick-action-throttle

I've done this and it's great for a free mod......but doesn't take 20% out of the twist, I'd say 10% max?

There isn't enough room in the existing housing to fit anything bigger, so it's going to need a new throttle assembly to get a quicker QAT.

OK cheers for replies think I may go for one of these:

had one previousy with a 50 cam on my last bike, emailed and they do one for the T (lots cheaper too).

But may have a play with the stock system first

I think cammo boy newelly was nearly onto something the other week.

if you remove the throttle completely you can just use the kill switch, on / off :roost

Yes.

The control is a bit rough having only "on" or "off" ... but for the 3 days it took me to find out I did save 100% of the fuel I would otherwise have used.

Well today I made my own:

Started off with some 1" sanitary pipe I had lying about, cut off the relevant width and tapered the edges with sandpaper.

Pic of an early production

Whacked it on with araldite, and placed back in housing but would not return very well so had to modify it again as was rubbing, ended up cutting the return half of of the white pipe off as it was sticking, you dont need that half anyway its the circumfrence difference in the throttle half that will create the quick action.

So it worked, snapped back into place and was evident there was less twist.

The movement is now 19mm the circumfrence of the barend is 103mm so by my maths thats 66 degrees of twist to full.

If anyone wants to measure the amount of twist in standard throttle will work out the difference between the two.

Right best go see how it goes :scared

Well thats much better, not too harsh at all but allows you to give it the beans in one short stroke, not sure if a 42 tooth would be a bit too flighty with this mod......

....but will try it and find out :thumbup
