Since I had the carbs out anyway, I was thinking about the R6 throttle tube mod that our SV buddies do. Basically it has a different cam setup to pull more cable for each turn of the throttle, turning a 90* into a 1/6th.
Being the poor guy that I am and also with bum wrists from work and sports through the years, this appealed to me. I did notice that I had to switch up my grip slightly to go WFO from idle and it really made driving out of certain corners a bit more painful. Here's how you can make your own for not so much (free for me):
-If you have a bike shop nearby, get yourself a 5mm 1 1/8" headset spacer, aluminum if possible. The carbon ones are too thin.
-Remove your throttle tube and place it against where it where the cable goes in. Mark where the nylon is and cut the headset spacer to match (hacksaw and vise).
-Slide the cut spacer over the area that the throttle cable rests and reassemble. You'll have to slacken your cables a smidge but not so much.
Result: 1/4" less throw in the twist. I don't know how much that equates to degree-wise but basically allows you to have much less wrist movement to go WFO. This of course makes your throttle much more sensitive so use at your own risk. No mods are necessary to the switch assembly etc. when using headset spacers. If you make your cut accurate enough, no need to glue either.
Of course, you can use PVC like the R1 guys do but that's on you, it's thicker and may not work as well. Numbers wise, here are the changes:
Before: 29.5mm throttle barrel
After: 30.5mm throttle barrel
Good luck!

Yeah Randy, I need pics. I'm sure your description is up to its normal high standards but I can't picture this one.... and I have a headset spacer in the garage (think it's 5mm). I'd love to not have to reposition my grip to go WFO on the race bike.

Alright alright.

Reduction in throw
Rob, I'm not sure if this will work for you because I don't know what the dia of your throttle area is. If you have some calipers and they size out like this does, this will totally work.
Expect a 15% reduction in throw with this mod.

Back in the origional Star Trek days...
Kirk: Take us out of orbit Scotty, Warp Factor One...(WFO)
Or as Sven said Wide F...... Open.

Finally got round to doing this omg it's good. For anyone who hasn't done it i would reccomend it. Not like the 400's a power monster so you won't scare yourself but it makes the bike so much easier to get on the power.

I did something like this when I noticed I had about 5% throttle left in a corner because I couldn't move my hand in time in the local chicane. Works like a charm :beers:
