With the good midrange torque of the '12 Wee I though I might like a 16 tooth countershaft sprocket ( stock is 15t ). Around here I have to cruise at 70 mph and higher to keep from getting run over from behind and even out on the backroads it seemed the engine was a bit busy at 60-65 mph.

The new generation Wee has the speed sensor fixed to the countershaft like the Vee does. So, any changes in sprockets changes the speedometer reading at a given speed. Well, the 16 tooth is absolutely perfect in that respect! Riding with the GPS the speedometer is either EXACTLY what the GPS reads or sometimes 1 mph higher. I consider that about as good as it gets. I'll have to see how close the odometer is, but I would much prefer the speedometer accurate even if the odometer is slightly off.

At 70mph the tachometer is right at 5,025-5,050 rpm. The engine seems a lot more relaxed at even 60 mph and it still has plenty of roll-on power in 6th gear. Taking off in first gear is not much different, I was worried I might give up some there but not enough to matter. Gears actually seem better as there seems to be more "difference" between 2-3, 3-4, 4-5, etc. I didn't do this for fuel mileage or to make the bike last longer, just for more comfort.

Where did you source the countershaft sprocket? What brand?

I stopped by one of the local Cycle Gear stores. I think it was a Vortex brand or something like that. Part # 2910-16. The #2910 is what fits the bikes like the DL 650, GSXR 600, SV 650, etc. so they are easy to find about anywhere. GSXR's use the 16 tooth stock I think so that means everyone stocks them.

We live in an amazing time. Thousands of songs and photos can be stored on a chip the size of your pinky nail. Our cell phones will answer any question we ask of them. Cars can now parallel park themselves. So Suzuki finally came out with a new 2012 'strom and still can't get the speedometer right?

The speedometer would always read several mph faster than actual speed in normal traffic conditions.

Don't ask what the difference at around 100 mph on the GPS read on the speedometer..........allegedly and on a closed course with professional rider, etc.

Sounds about the same as my 2005. It always reads 10% high. An indicated 55mph is really 50, and 110 is really 100. Is it about the same with the 2012?

Thanks, RS. This is what I was talking about in my "bike seems tight" thread from yesterday. So you too notice a diff from the earlier bike, yes?

Our '04 has the pipe drilled out and the extra noise from the cam/clutch area made that bike seem about as happy at 6000 rpm as 5000. Noises were about the same. But the new Wee II is much quieter and when running over 5000 rpm seemed "busy". Probably because the noise seemed to increase? Maybe that is what you mean by tight.
I am sure it would run at 5500 rpms for days on end, I just wondered if the 16 tooth sprocket would make it feel better and it did.

I don't think it's the noise diff, though they are different. Will give the gixxer sprocket a try. Cheap experiment.

Is the chain long enough so you don't have to add a link? :confused: This would shorten up the wheelbase a bit too. How about a Sunstar part number? I found it, it's 40416 for $22 bucks. I'm gunna go get one.

I will try this here pretty soon too. Hell, I may just run to Bob's Cycle supply this afternoon and get one! :thumbup: I assume the cs sprocket is put on with that nasty orange loctite Suzuki uses??

How is the 16T for slow speed? I like to do some mild off road and do use first gear a lot for that, and I do not want to loose the throttle response when off road. What do you think?

Chain is plenty long for the 16 tooth sprocket. I doubt the difference in wheelbase will be noticeable. Yes, the orange loctite is there. My air impact wrench didn't notice it! BTW, the countershaft nut is 32mm so have that size socket or get one for the install.

Really not much difference in low speed/first gear. If anything it took some of the sensitivety out of it. For pure off roading the 15 tooth will be better or even a 14 tooth.

I ordered my new sprocket (14t) from Blair at SV racing, it was $28. I didn't feel like doing any research & I know if it comes from SV Racing, it's among the best that can be had. I guess I'll need a speedo healer.

I just picked up the Sunstar sprocket I mentioned earlier, $22 bucks.

I'll give a ride report when I get it on. It's geared pretty good stock, so we will see if it loses some of it's spunk.

Hmmmm, a good percentage here do their own homework. Fer instance, only the OEM Suzzuki sprockets are rubber damped. Why does Suzy do that?

Today, after a spirited ride following Black Lab on Mount Desert Island in Maine, I decided I'm sticking to stock unless I can find a used gixxer sprocket for free to test. The stock gearing is just too sweet to give up that torque in favor of revs.

I have though about going down to a 14 for better throttle response off road, but I do too much interstate riding and don't want to have the higher RPM. Ideally I wish the trans was a little more wide ratio, with lower first and second, and a little higher 6th. Maybe since sprockets are cheap, I may experiment with a 14 and 16 later this year or next year.

Lowering the chain noise is all I can think of.

Anyway, I got the new sprocket on already. Took less than an hour. You need a 1 1/4" socket (for the CS nut). Breaker bar when the engine was warm made it come off easier. The chain is plenty long too.

I'll go for a ride tomorrow!

I've been doing lot's of homework, too much. Luggage, bars, center stand, fork brace & on & on, for the sprocket, I felt like Blair would definitely get me what I needed. I have never heard a bad thing about his service or advice anywhere on this forum.

According to SV R & some other thread in the 2004-11 forum the rubber is not needed provided you have a high quality, perfectly fitting sprocket.

That's what I did. I'll let you know what I think after I get it installed. Hopefully tomorrow night. I try and avoid the freeway as much as possible, I don't generally commute & plan to do a lot of touring on my strom in developing nations. I'd also would have liked to have seen a little wider gearing. I don't feel much need for a taller 6th (6000 revs is about 80mph, 85 indiacated), but I would like to see 1st & 2nd pulled back a fair bit & 3rd & 4th just a tiny bit.

Been there done that. I put a 16 tooth on my K7 and it felt a little lacking in the torque department. I did not notice an increase in MPG. While the Glee has a little more mid range torque, well lets just say I like it that way and plan on keeping the stock 15 tooth.
