I just took it for a burn down the road. I did three runs. Two into the wind (about 5-10mph) and one with the wind. I’ve got the full glass OEM windshield and the rear OEM glass. I used the gps app on my phone.
1st run 63
2nd run 63
3rd run 64
All seem consistent with others. Cruising at 30-40 is definitely quieter and cruising at 50 is no problem at all. Almost feels like half throttle although it’s not.
Throttle response is greatly improved. Stomping on it at 20-25 breaks the +28” tires very easily. With the little bit of running I’ve done, I’d say I’m very happy with the results and it’s a pretty easy mod. Cheaper then the pipe as well but I’m glad I’ve got both [emoji4]

Guess who's back to 22 gram weights. Timmi has stated multiple times that he doesn't do a whole bunch of high speed riding and mostly low speed stuff so why the change after a whole year? Timmi's been running stock tires for over a year. It's taken JBS over a year to figure out heavier weights are better.

I've been preaching this for almost a year now:

https://www.wolverineforums.com/for...2-x4-cvt-sheaves-wet-clutch/21066-wolverine-x2-x4-clutch-mods-2.html#post271136

JBS camp is also making fun at Todd selling his X2 with 50 or so miles on it. These clowns don't realize that a large portion of the sheave testing has been done on my X4, with over 7K miles. That's literally 600% more mileage than Timmi and James vehicles combined.

Here's JBS thread pimping out 16 gram weights:

https://hotrodforums.net/forums/showthread.php?7190-Yamaha-X4-14g-vs-16g-with-27-quot-tires

With James\JBS they always use half-lies such as this: "tincan says 14g is faster...he must do it by feel...lol" What James doesn't disclose is that Tinken was advocating for 14 gram weights in the Wolverine Gen 1 708cc, NOT the X2/X4.

Same JBS lies with stating they were the first to mill the sheave towers. What James doesn't say is that they ONLY milled the sheave towers to accomodate a different cam plate on the older Rhinos:

And finally James is always spouting how HW steals his ideas and copies him. This moment, permanently etched in history should make it crystal clear where JBS refers to 'Hunterworks OD weights':

 
Well, I'm writing this with some regret, but I always find that information can be valuable even if it is not what you want to hear. I have installed my Hunterworks sheave with 20gr weights (as suggested) on my totally stock X2. I filed the cam plate (as suggested) to prevent/minimize the scrape effect. I also sent out my ECU for the Weller reflash. I installed it all without issue and took it for a test run. I ended up moving from the stock 83km/h (51.5mph) to 92km/h (57.2mph). An improvement of 9km/h (5.7mph) increase in speed. I thought this was not that good as I was expecting more. I took it all apart, checked out the install (all good) and reinstalled again. Test runs came to the exact same conclusion. Did I get an increase in speed - yes, approx 10%. Did I get benefits of the reflash such as adjusted cooling fan cycle temps removal of speed limiter - yes. Being from Canada, with the exchange and shipping and customs fees, I paid around $1000 for this increase and still didn't get to the magical 100km/h (62mph) mark. I am overall disappointed, but it is what it is.

I do want to emphasize a couple things - Todd at Hunterworks did reply to my questions and he feels confident that there is no sheave issue. Kyle from Weller Racing helped me out with my questions and helped me with other ECU related asks. MassiveOverkill also replied to my PM's and offered some ideas. All these guys tried to help me out. In the end, this is my findings - I did not hit the mark with my set up. Thought some people might benefit from my end result.

Stroodle, 18 gram weights are too light for stock size (26") tires in my opinion. Todd is offering those who bought a sheave a 2nd set of weights at cost. I'm hoping he'll honor this price even if you buy the weights after the initial purchase. I'd really like to see you give 20 or even 22 gram weights a shot. Even clean up your stock weights and throw them in there to see.

Sorry to hear your situation.
I can hit 57 mph and all I did was 29" tires and currently 20 gram weights.

MassiveOverkill - I should try that - I know you suggested that in the PM, I didn't try the OEM weights. It kind of sucks pulling everything apart to get at the clutch, but it would be nice to get that speed up! I'm heading out on a giant hunting trip soon, I will try and get to this before the trip and get back to you all. Thanks for the quick reply

My memory is terrible you said recommend 18gr weights but 20gr are recommended for stock tires, however both will achieve the same top speed.

Once the clutch closes all the way around 45-50 mph then you are simply at the mercy of how much power you have to propel you. Stock tires are somewhat slower than the larger, we consistantly see 60-64 mph with 28" tires with 18 and 20 gr weights, as mentioned weight of weights do not affect top speed. So what rpm are you at at that speed? Any idea? is it screaming at you?

In meantime watch this, it is more about polaris but the physics work exactly the same way.

Todd,

I was wrong - 20gr weights - I changed it above. Thanks. Something else I may try is a new belt - mine should be fine at 5000km's, but a possibility I should rule out.
 
MassiveOverkill - did you give me the handle under my user name??? Ha ha! Seems fitting for my issue!!!
That name changes as your post count goes up, start looking at other folks, some of them are really fitting and funny at times.

You have 5000 km on this machine? And you recently did these mods?

Two things, that belt surely has some wear so that can account for it and that engine is probably getting tired a bit. And lastly your tire size
 
5K is nothing, with oil changes etc it should go 2 to 3 times that easily.

Agreed I've seen Rhinos with 20K + miles and still running strong. It's all about maintenance. No reason the Wolverine X2/X4's won't run 20k, 30k miles.. My 08 Rhino had nearly 10k with zero issues and on the original belt. However I maintained it properly.

5000 km -tired engine??? WTF??? I had 30,000 km on my Rhino engine and it is still going. I maintain my stuff pretty well. I have put 700 km on in a single weekend! I hope you just read this wrong! I did the clutch mods about a month ago - immediately after they became available. I still think the clutching did little to nothing for my stock X2 - for the 8 km/h I gained, I think that was due to the ECU programming removing the speed limiter. I might reinstall my stock clutch and stock weights and confirm. Too bad, I was excited for a while.

I am curious to hear your results. I have 28" tires and the weller flash and I am getting 57 mph. I think just a lighter weight will help me get up over 60 mph. I think that due to the larger tires, I am not getting full shift out. Other than that, I am very happy with my setup and hoping to avoid doing the sheave. I may, at some point try going a little lighter on the weights to see if that allows the engine to rev a bit further.

In your case, you are probably correct. On stock tires, these machines are almost too torquey. The sheave might have given you more bottom end and maybe some better accelleration. I don't think the sheave can give you more top end unless it is allowing the belt to run higher. Larger tires would be the only solution for more top end.

Lighter weights will just make it rev higher at lower speeds, not what you want.

This should be your typical experience from a machined sheave upgrade:
