1/5 turn throttle

MotoVegas · 02-22-2008, 02:13 PM

(Not sure if this is the right forum)

Anyway, was thinking about putting a 1/4 turn throttle on the bike. But first, I plan on sticking a spacer to pull the slack out of my 1/5 turn and "transition" slowly to a 1/4 turn (i.e tighten it up for a couple track days via the spacer, then make the switche to the actual 1/4 turn).

Any insight/experience/thoughts on the subject? Your musings are appreciated in advance!

Why do you want to go to a slower throttle? You would need to turn the throttle 90-degrees to get what you are now getting in a 72-degree twist of the wrist.

If it is for a snatchy throttle, you will see some benefits from getting the slack out of the throttle cable.

Your ZX doesn't already have a quarter turn? Most modern sportbikes are nearly so.

A 1/5th turn is "faster" and harder to use in some ways (though I love them).

Whoops, backwards statement by me. Thanks for pointing that out (I need to lern2fractions).

Anyway, yes it has to be a 1/4 (i.e 90 degrees) turn on there now as I find it difficult/uncomfortable to roll my wrist/hand to WOF while tucked on the straights without completely reposititioning my grip (which frankly is awkward). Sometimes (read as most of the time) being the "wrong size" human being with shitty flexibility and riding these bikes is a major PITA.

So, my topic should read, 1/4 throttle going to a 1/5 throttle, thoughts on that.

Yeah, just do it.

Don't mess with spacers or tension. Install it properly and use it.

Be sure to tell people you loan the bike to though.

I LOVED my 1/5th on the 600RR. Must have mod, IMO.

The hot set up on the SV was a R6 throttle tube which was 1/5 turn and cost $11.00 versus the $135 for the one Yoyodyne sells. Maybe there's an inexpensive option like that for your Kawi.

I have less than half the HP of your ZX-10, so be careful..

Actually, I bet you'll get used to it quickly.

I did this to my gix600 (only it's an R1 throttle tube for this bike). I haven't tried it out yet, but this bike required me to reposition my hand (move it and regrip) when getting to WFO on the track. I never had that problem on my 929. I'm looking forward to trying it out this upcoming season.
