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.

I bet it would make turning the engine over a little easier but in operation i don't think you'd feel the several hundred spent to get there. I'm with you on chain drive being fine

That's interesting. I've been to engineering industry talks about changes in car engine design, to reduce parasitic losses, increase performance, reduce noise and emissions, also improve fuel consumption. It's disappointing to discover that the MoCo has missed that, although I suspect the chains are less noisy than gears.

I bet that's it. A little extra gear noise would equate to a little less exhaust noise to meet regulations.

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 was wondering where you were...

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.

how do you check the run out at home.

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?
