This was posted by Yamaha Nutz in my build thread, maybe it will help.

I've been running clutches stock on my phazer with the 144 x 2 and it's been working well, however I'd like a higher engagement so I'll be experimenting when I get time.

yes the splines are different on the drive shafts ...........like what was said the bender pipe and Aaen pipe are the same .....with stock carbs for your year sled I would bump the pilots to 110 and the mains to 148.8....for flat slides the 95 600 38mm carbs just require a main jet change the rest for me at least was spot on but my motor is nowhere near stock the SX cut on the pistons is a easy 4 hp and helps the bottom end and mid range a lot .....if the primary has the 87F weights run those with the red/ green spring and stock secondary set in B-2 should come in at 4500 rpms and rev to 72-73
