2017 Kodiak 700 ESP SE
Here is a helpful tip from EPI Performance
..same for me, i ordered and heard nothing for about 4 weeks and got no response on Emails. But finally he answered and my order arrived.Well today I took the stock spring out of the secondary that was on bike, gonna order a purple spring for it since that is the general consensus that works the best or that would be closer to what I need
Man I am not trying to bash anybody but I have emailed, facebook message and called 3 times and cannot get a response from JBS for the stuff I ordered. Anyone else have this problem with them? I placed an order last month and it was lightening fast getting here, if they don’t have it in stock just let me know and refund my money
This information is not for the Yamaha setup. This is for a snowmobile type setup, where the clutch has a tapered bore with a tapered crankshaft to fit onto. Much like a tapered ball joint stud or tie rod end stud.
I also had the 17 gramm weights, but went back to 20 gramm. Fuel millage was very bad compared to the Stock weights at least 20%. Also RPM was way to high while cruising, didnt sound healthy and was very annoying.
Maybe depends on riding Style but for my type of riding, i experienced, a bit heavier weights than the stock 18 gramm fits better. Also due to the purple Spring the RPM are anyway higher by holding longer in lower gear. And m.p.g is almost back like stock now.
15% lighter weights with a 20% decrease m.p.g. That stands to reason and if you had been riding w.o.t. a lot the m.p.g. would have been worse.
The weights react to rotational force, so less weight in/of the weights requires more engine r.p.m.s for the weights to move and increase machine ground speed.
So when cruising the engine was running faster, more noise with nothing gained.
This is pretty much what I'm running, 26" tires, machined sheave, 18gm weights and purple spring. It's a very nice setup, lots of torque, yet great trail riding ability.Ok tore everything down today and went ahead and just put purple spring in and 18gram weights
I haven’t got to ride it a bunch, but I like it.
The best way I can describe it to me, the machine feels sportier, faster all around just feels better
I am keeping this combo
I am writing this to hopefully help someone down the road on mods to their grizzly.
I’m Speaking from first hand experience with my machine.
I have done the shim mod, all the way up to 1.8mm shim. Then I did the 4/450 weights and 4/700 weights. After that looking for more low end I had Coop45 machine a new sheave for me (mod#3) and went ahead and had him get me a secondary from eBay, he serviced it for me and installed a EPI gold spring, I went ahead and added a .5mm shim with his sheave and a new OEM belt while I had it tore down again.
Ok had this thing apart several times, put back together several times and everything was put back together by specs and TQ’ed to spec.
I am going to be brutally honest here, and I know every machine could potentially respond different (meaning some better than others), on my machine there was no night and day difference between all the mods, it did respond and runs good, but I am not getting easy wheelies like some people say on-here with 28’s again maybe their machine responded better than mine and yes I am jealous lol, but seriously I have put a good bit of time and money in machine seeking that one thing that would blow my mind, it didn’t happen with 28 Zillas on my machine.
When it was stock and had stock OEM tires she would pull the front up with ease in high and felt quicker, being honest here.
The big difference in my machine was the tires, 28’s take away a lot from my machine anyway, point pick your tires wisely first time around and if you go big be prepared for the loss, again maybe your machine will respond better hopefully it will.
I am going back to 26” tires soon
Hopefully that little bit helps someone and don’t spend the $$$ to chase that better power, my conclusion is the grizzly just don’t have the grunt let’s say like a brute force, canam twins and you will continue to chase something that’s not there, be happy with a super nice, reliable and very capable machine but not a powerhouse.
Glade your happy! Thanks for your info, it helps everyone here, everyone has a different riding performance they are looking for, and it sounds like you found your sweet sport!Just an update to anyone who is looking for a good combo
after doing a lot of experimenting with clutch set up and mods on machine this is what I finally feel is where my bike runs the best, actually runs like gangbusters lol
Coop45 #3 mod
18 gram weights (all 8)
EPI gold spring in secondary
I adjusted my EHS controller to the recommenced setting in the instructions from EHS
HMF swamp series slip on
EHS air lid
she will rock n roll now, go over backwards in high with almost no body English, in low hold on snappy as hell
This combo flat out gets it
