Well heres what i have. 99 rk mm f.i. 98" cyl/piston & heads done by Dan Vance (set up for my cam choice), 10.8:1 cr. talked again with bob about cams could go with either the
tw-8-6-r or the tw-9-6-r (going with hyd/roller conversion kit) any thoughts on which one i should go with. ride two-up part time with solo bar hopping and local hog runs.

 

I love my 9b. Plenty of lowend for 2up riding and pulls hard all the way to redline. Don't have any personal experience with the TW8 but have heard the 9b is actually a little quieter.
