Putting a file on that edge as Todd says should prevent this hopefully.

That is a GREAT wright up.
Thanks, Will

Will Griffin's test results (he's not on WolverineForums unfortunately)

Looking at this again, I have a question.
How did it get quieter at idle?

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 18gr 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.

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

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.
