Cam advice needed..

RE: Cam advise needed..
IMHO...i'd recommend you stay with a set of gear driven cams (to avoid the cam chain shoe replacement) and onethat is made specificallyfor the best lower end performance (torque). Lot's of manufacturers out there to choose from...like S & S, Mackie, Andrews...for me the SE257 has worked the best, but they're not gear driven.

Odd Job, that was true in the past with the old style chains and tensioners, but the new hyda type are a very good design. Granted the tensioners will wear out at some point, i am not fond of the idea of geardrives with no cam beaings...
I also like the woods 6, but and andrews 26 or 37 or some HQ cams will all work depending on riding style and wants out of the motor.

The Head-Quarters 500 cam is an excellent bolt in cam. I use the pre-'07 chain version (HQ-0034 cams) and it's excellent. You can use Big Boyz cam comparator to see the different lifts and cam timing specs for three cams at the same time:

The intake valve's earlier close on the HQ 500 tends to create more torque earlier in the rpm range than cams with a later intake valve closing. Personally, I doubt that my butt dyno is sensitive enough to notice the difference.
Also, to get the real benefit from the cams, you will need a high flow a/c and, in any event, a fuel management device (SERT, PCIII, etc.)

BAGGERDSM...I hear what you say brother...that the new Hydro Tensioners are a lot better....was even thinking about retrofitting my old spring tensionerswith the more recent Hydro ones, the dealer says it's possible, but reminded me thatI would some day have to deal with the "shoe" again. They said hold off, keep checking the shoes, andwhen that time comes near to replace again, thengo with the geardrive cams.
I'm quickly approaching 77,000 on my bike...35,425 on the bike when my first pair of chain tensioners lunched themselves (luckily I still had a warranty, so they replaced everything for free, sans my SE257cam) Figure if lucky, I have about another 5,000 max before the next failure. Next time for sure gear drivers and a Fuelling Oil Pump...keeping my fingers crossed in So. Cal.!!!
