I have a 2013 XTX and have been dealing with it hitting rev limiter on WOT pulls. I can get to about 107 km/h and it wants to hit the limiter. It has Dalton weights, stock spring in primary and secondary as well as stock helix as that is how I bought it. I was on the rail line and kept throttle just below rev limiter. I let a little bit more off and it was like it switched gears. Engine lugged down to about 7300 rpm and I could hold it WOT and get up to about 150 km/h at around 8500 rpm. I have to repeat this every rail bed pull so it won't hit the limiter. Any suggestions on where I should start. I will be getting it into my shop to start tearing into it here in the next few days.

Have you checked the actual weight of those primary weights?

I have not and will need to. I added more weight a few weeks ago assuming it could pull more. Saturday was my real first ride since doing that when I ran into this head scratcher. I do need to tear into it more but just need the time to do it. Just found it odd that it did what it did on the weekend.

Weights may be grooved up and rollers may be getting hung up in the grooves. Seen this many times on the three hole Yammy’s. Pull the clutch and inspect all the cam arms for wear. At the very least pull the primary cover, spring, weights, rollers, pins etc. I find it easiest to pull the entire clutch. I’ve got a puller if you want to borrow it.
