Just bought a 14 zr7000 lxr 129 for the wife and need her to be a bit faster than my friends viper for the times I ride it over my turbo haha.. Hes got a 16 viper 137. Any thoughts on clutching?

Back in 2015 a few of us had this same conversation: https://www.hardcoresledder.com/forums/493-procross-2012/1496753-somethings-not-right-xf-7000-ssi-kit-install-help.html

With the SSI clutch kits, air intake and with the Can my sled (2014) gained over 4 links compared to stock 7000 from hole shot, top-end was still the same, I didn't change my gearing. The air intake and can allow the four stokes to breath.

The dyno sheet is not my sled but same motor.

Ulmer racing has a really good set up for the 7000

That's where my intake and Can came from. Back in 15 he didn't have a clutch setup for the Cats. Ulmer does know his Yamaha motors.

How about studding? This has the premarked stock track 2 singles per bar but has anyone staggered a double per bar instead?

I did on a 8000. It was not enough studs for that sled. It might work on a 7000 as they don’t make much power. I did a 4 2 4 pattern. I should have done 4 per bar.

Do the airbox mod, torsional conversion clutching and i run 22/48 gearing. The gearing change didn't hurt my holeshot at all and it runs 104 on hard pack. I also run the straightline performance can. Very nice gains over stock.

The 7000 doesn't have as much HP stock as an 8000 but the 7000 has plenty of low-end torque.

If the op is going to stud the track I would not short himself I would go with 4 per bar also.
