Darkhorse/S&S/WFO Larry 117" build time.
I'm running the stock chain setup. I think the modern hydraulic setup is plenty reliable so I wasn't concerned about that. However, at a bike show a few weeks ago S&S had camplates set up with a old style spring tensioner chain, a new style hydraulic tensioner chain, and a gear drive setup. The gear drive required noticeably less force to spin, with the spring style the most difficult to turn. Not sure it would equate to a measurable power difference at the rear wheel, but it was something.

Excited for ya, should be a lot of fun!
117" was a good choice, if I had checked my crank runout before buying parts - that's what I would have done...
Any clutch upgrades for the extra power?

I've got an AIM VPC, a Barnett spring (not the heavy duty one...can't remember the part #) and Barnett clutch disks already. Hopefully that's enough, but we'll see.

I was thinking i could have the dealer do it but, at that point. The chest is open and the labor is 1/2 done. Why not just in stall the cams/gear if with spec..and chain cams if not... that would require having both types of the chosen grind on hand at thhe time of testing to avoid basically paying for the cam install twice. By having it tested then getting a set of either then going back in for an install.
does that make sense or am i under thinking this?
