I just purchased an ultramax excentrik today. I’m going to be scaling a getting setup for opening weekend in April. I havjt raced in close you 15 years and never ran umax. Can anyone tell me anything about the excentrik. I’m not familiar with the “pills” for the rear end. If anyone can explain what their for it would be awsome. I downloaded the basic setup for numbers of the ultramax website. Any other info and tips would be great. Located in the Huntington Wv area, thanks guys.
 
What year? There are essentially two versions of this kart. The 10-11 are the same and the 12-13 are the same, but a few minor front end changes on the latter.
 
I’m not sure what year it honestly. I got it from my local parts guy and never asked. I assumed I’d see the serial somewhere but I’ve looked all over and couldn’t find it. I attached some photos for some possible help

Looks like its been run on dirt . Could just hop in and let it rip .
Hang tight someone will have numbers.
 
That is a 10-11. Racing promoter will be able to give you numbers for it for up North. That kart has seen better days for sure.

It’s definitely been raced. But it was a cheap and decent way to get to go race along side my son. Just hoping to be competitive to a point

I’ll be running Akra lite and medium 325# and 350#. Running at wheelersburg raceway in wheelersburg Ohio, it’s a 1/5 mile high banked track. 33a tire rule.
Will also be at willard kartway some in willard ky, flat track, dry dandy. Any Burris slick tire. Not sure how big the track is but it is long straights and tight corners. As well as tyler mt kartway.
 
56.5 % to 57 % left, 57.5 to 58 % cross,
46.2 to 46.7 % nose, 2.6 RF neg camber,
.5 LF pos camber, 1 1/4 " front stagger,
Rear stagger track dependent but 1/4 " more than most everyone else is using, on the 1/5 mile start 1 1/4" on the tight turn tracks use 1 3/4", PM me to discuss wheels spacing, caster, seat placement, and last gotta drive it like you stole it.

Awesome thank you! I really appreciate it.
 
Serial number is on either the brake pedal bracket welded to frame or the gas pedal bracket that is also welded. Can’t remember which one it is. Looks to be an 2011. 2010 had the thinner L block castor plates. 2011 had thicker ones. 2012/13 totally different chassis same rear end design….. no pills in the back as well. Just castor pills in the front….
