I bought a 2016 Kodiak SE recently and my first upgrade was a set of 26" Bearclaw tires. Having ridden 2-3 hundred miles on a different 2016 Kodiak that was all stock, I had a good point of reference for feeling what I felt was a pretty big difference with the 26" tires over the stock 25's. It felt lazy... especially in the mid-range... it felt slower to back-shift and it just didn't pull through 40-50 mph very strong. Top end was 64 MPH (would touch 65 occasionally), the stock one was a solid 65 hitting 66 once in a while.

I bumped the fuel mapping a bit to alleviate the lean running condition which makes the machine start and run better... I feel like I could notice improved throttle response. :smile2:

I also ordered a set of Yamaha 21 gram clutch weights (courtesy of a 2014 Grizzly 700). After changing oil (10W50 Yamalube) and filter for the first time (@ 165 miles) I swapped in the lighter weights.

I have noticed a massive change in mid-range... actually superior to the stock machine. This has more than compensated for the heavier 26" tires. In a zero-60 run I can stay pretty much exactly even depending who hits the throttle first. (Wife always jumps the gun... cheater )

I am a bit confused though, I thought it would have a stronger bottom end too, but the stock gets me every time from a dead stop, about one-two lengths right off the line... If we hit it at about 15 MPH, then I pull away instantly a length or so.

It pulls much better throughout the rest of the range now... with the speedo jumping 2-3 numbers at a time... right up to 59 MPH or so, levels out around 63-64 MPH.

Overall I'm very happy with it, I didn't go 18 gram weights as I wanted to maintain quiet, lower RPM trail operation and the Kodiak's awesome fuel economy. So far... mission accomplished.

I am planning to add anti-friction washers to the secondary soon, and I might try JB's machined sheath in the future... to see if I can gain some hole shot capabilities without loosing top end.

How did you accomplish the remapping ? Did you install an aftermarket fuel optimizer or was able to reprogram the ECU yourself?

Interesting read. Keep us updated!

Could try shimming the primary for the low end boost. Cheap and easy to uninstall if it doesn't meet your expectations.

So I made my clutch mods...
I am running 26 in. I.T.P. XTR,S Heavy but not all that tall.
I prev. owned a 700 grizzly and did not like the rammy user un-friendly bottom end in low speed and real rocky areas.
So on the 700 Kodiak I did a 1 m.m. shim mod and I staggered my clutch weights with half 30 gr. weights(stock 700 Kodiak) and half stock 20 gr. grizzly weights.
I think I nailed it! Nice smooth easy to use bottom end.
And it revs nicely and does not shift out so quickly. No excessive revving or rpm.
For me this set up is perfect. It is the best of both worlds.

Very nice write up! I'll keep following your updates.

How were you able to bump the fuel mapping?
