The awesome of 16-43
Just went to 16/43 on my bike. It rocks. Front end comes up very easy in first and clutches up nicely in second. The biggest improvement is how much harder it pulls on the freeway in 5th and 6th gear. Thats all I have to say.

Not much diferent. 5000 on the tach is about an indicated 80 mph. 5500 is about an idicated 90 mph. Which is really more like 72 mph to 81 mph. It pulls very nicely and my fuel millage does not look like it has been affected to bad.

About how fast are you going at 5000-5500 with the 15/43 gearing set up?

I had 15/43 and now have 16/43... Prefer the 16/43...
I ride interstate, and lots of back roads, so it doesn't kill the mpg as bad at same speed, but it throws the front end up way better than stock...
When i got my tires swapped out, i went back to stock rear sprocket for about 3-4 day's... then decided i didn't notice enough difference in rpm to not have the better performance....
after doing some non mathematical math.. i reached the conclusion that i was only seeing about a 200-300rmp change in that gear swap...

im a big guy and ive got a hard enough time keeping the front end down with stock gearing. if i roll into it in first she comes up, if i snap it in first well she comes up but much much harder, lol. ill be doing a gear swap anyway just gotta hold on and enjoy the ride i guess. lol

I have 16/43 set up. Like a dirtbike, I feel it is better to enlarge the rear sprocket for gearing rather than go smaller on the front. My reason is this; drag. The smaller diameter of the 15 tooth sprocket will cause more drag on the chain slider on the swingarm. Now how much drag and or power reduction is caused by this on the SH I do not know. So I opted to not to go that route and added two teeth to the rear sprocket instead.

15/42 (-1/+1) is a good middle-ground. In terms of ratio, it's equivalent to going up 3.8 teeth on the rear sprocket, as opposed to 15/43, which is equivalent to going up 4.87 teeth on the rear. Dropping 1 on the front by itself is actually more of a hit than going up 2 on the rear. Thus, in order from tallest to shortest, here's the combinations that I understand will work with the stock chain:
Front/Rear (Equivalent teeth up on rear)
17/41 (-2.41)
16/41 (+0) -Stock
16/42 (+1)
16/43 (+2)
15/41 (+2.73)
15/42 (+3.8)
15/43 (+4.87)
Not sure, but I don't think there's enough adjuster slack to allow 16/44 (+0/+3) with the stock chain, but someone who's tried may be able to confirm or deny.

I'm using 16/43 and I think that is about the limit for the stock chain. Somewhere here is a spreadsheet that gives the numerical calculations and the MPH at various RPMs for different tooth set ups.
I recall that for 16/43 in 6th within a tenth or so 3000rpm=50mph, 4500=75mph, 6000=100mph. I don't run a speedohealer, but with numbers this easy I just use my tach and convert in my head

Nope it won't work. You can run a 16/43 with a stock chain but any larger on the rear and you will have to add a link.

I run 15/43 and couldn't be happier. I'm not a stunter but do enjoy power wheelies and for what it's worth, everything is underpowered up here in Denver compared with sea level. I commute everyday and find the power very useable but certainly notice less pull at triple digits. After some trouble with the law I don't miss the top speed, personally, if I can beat everybody to 100 mph and then I get dusted that’s good enough with me. But I know for some it's not...
