Best Performance oriented upgrades for the 116?

2015 Views 14 Replies 9 Participants Last post by  Skidmore111
Right now I've got a '21 Chieftain Elite with the stage 1 Indian intake (2881779-521), Rinehart slip ons and stage 2 Indian cams. With the Dynojet PV3 I had it put on a Dyno and got 126tq/106hp. I want more.

I've seen a few posts on here from a few years back that claim someone has 140+t/117hp? How can I achieve this kinds of numbers without voiding warranty, or sacrificing reliability (the bike is my daily - no car).

I was considering the Lloyds big bore build but im on the west coast so if something goes wrong with that I dont want to be hosed. Recently I've been looking into the Rinehart slimline headers (100-0553) since they now make ones that will fit the 2021's and that will get rid of cat heat as well as offer me some 18mm o2 sensors for better tuning.

So what are the best mods I can do from here?

116 ish HP 135 ish TQ is strong. A HP per cube on a pump gas air cooled bike. I'm just starting to learn the Thunderstroke. Is it a 2 valve head? Does anyone offer ported big valve heads?
I read 10 HP is 2 bike lengths per gear. If true over 2,3 & 4th gear you would pick up 6 bike lengths on your buddies.
