The other nice thing with the 43T rear. In 4th gear whatever my RPMS are equal my speed. 4k RPM = 40mph 5k RPM = 50mph 6k RPM = 60mph, etc.

Yes Michael, i knew that. But everybody says the speedo reads 6-7% higher. I'm checking mine since yesterday with my GPS and there is a difference of 3%. It is set in Km/h but i think it does not matter tough. Maybe i will install the sprocket tonight. So i will give you guys some news about it quickly.

There is a thread on here about this - I recall it being 6% error on the speedo and 0% error on the odometer - stock gearing.

If you add a tooth to the front, the speedometer error goes to near zero (+ or - 0.5 mph at 60 mph, per my gps, with Dunlop RoadSmart tires, mid-life in the tread), and the odometer under reads by 6%. So when you calculate mpg, you need to multiply by 1.06.

I have a 43t on my V (I am very happy with it). That is a 7% change from stock. When I get a reading off roadside radar units ("Your Speed") I am usually showing about 1 mph high in the 60 mph range. That is my main reason for figuring that my speedo is mostly accurate now. I know those roadside units aren't the best measure, but I seem to get very consistent results from unit to unit.

Ok 43t installed. Went for a ride. Happy happy happy. I was sure it was going to be harder to start from a dead stop but actually i think it is easier. It's true that it is mellower. Less compression braking? Not sure yet. Do note that i only did a 15-20 min. ride. The thing now is that before replacing the sprocket, my speedo showed 97km/h. when going 100km/h. on GPS. Now my speedo shows 103-104km/h. when going 100km/h on GPS. I will have to check my speed often to make sure not to get a speeding ticket since i lost that "buffer". I will set both my speedo and GPS to mph as soon as i can to see what it does. I will be going to the U.S. soon. Want to make sure it shows 40 on 4th, 50 on 5th....

I guess the 44t really gets the speedo spot on, but i don't see the need to put one. Just go to the 43t. It does not seem to kill the performance like a +1t on front did on my Raptor 700 atv, and it should improve the fuel consumption better.

This just came up elsewhere on the forum today...

There seems to be no problem with using the stock 114-pin chain with a 44- or -43 tooth rear sprocket. My experience is that a 112-pin chain will work just fine with a 43-tooth sprocket.

I changed my to a 44t yesterday. It was a pleasenter ride no doubt! You have a longer pull on the gears, it cruises somewhat smoother and there were less need to upshift and downshift as often as with the stock.

Filled up my gas tank today and will revert back on if there were actually any savings on gas milage.

All in, one of the mods I should have done a long time ago!

Running 44 back and front still on stock. There is some speed error on GPS vs speedo meter but not much.

Don't find anything really upsetting and bike is smooth on take off and all gears.

No one beats me on a traffic light junction.

I tried the 44 for a season then went to the 43. I am sticking with the 43 for sure. The 43 with a 150/70 Scorpion Trail yields the speedo bang on with the gps. Final solution found. Highly recommended.

Planning on changing the rear sprocket too in the next few months..

Here is a nice tool to use to figure up rpm's and sprocket- counter shaft size..

I know most of the people go with the 44t but i read somewhere that it "only" drops the rpms around 200-300. Not much to me?! And i'm affraid to have some diffculties to start in first or loose to much power on 6th gear with the 43t. I have done a +1t front sprocket(worth 3t on the rear) on my stock Yamaha Raptor 700 atv and saw big difference. So much that the last gear(5th) was acting like an overdrive. I almost had no acceleration. But that was before any mods i have done to it. Now it is fine because i have more power for that gear setup.

So my questions are: i would like to install a JT because of the low price but i think they only make a 43t for the V right?

Any parts number for a 44t and lowest price(best place to order it).

Thank you very much for your replies!

I actually run a 42T rear. It does not make my speedo more accurate. In fact I am running at least 1-3 mph faster than the speedo shows depending on how fast I am going. However, the drop in RPMs with a 42T rear is significant. I am running about 2000 rpm below my speed at 70+. This makes for a more relaxed engine at any speed. It does hamper off road though as you'll need to slip the clutch significantly in more difficult sections. For this reason, I carry a front sproket with me in order to change it out. Would be kinda tough to carry a rear sprocket with you. It's also very tough to get that rear wheel into the air without a rear stand. I bought a JT Rear Steel Sprocket 42 Tooth - 1263590069 - $31.99 at the time I bought it from Rocky Mountain ATV.

Hey guys

Just wanted to mentioned that you need to check speed accuracy at least at two level of speed

You could be dead on at one (lucky) and way off everywhere else

If at two (or more) different speed, your speedo and the gps are keeping up, then your good and safe toward the law, that costly thing that grabs all that hard earned money ...

My two cents

Lours - I think you'll either be accurate OR inaccurate, not a bit of both. Any error should be at a % difference. Suggest you check your INDICATED at 5,000 rpm and your GPS speed same time. That's a simple math problem to establish the % error in YOUR system.

For instance: at 5,000 rpm my INDICATED is 70 mph (or 110 kph), while MY actual is 66 (I THINK... - I'll check it NEXT ride), making MY error around 6% which seems close to what I've worked out previously.
