Just Bought A 2012 Grizzly 700 FI

[whoDEANie]

Ok so I went out and installed a two brothers pipe and a JBS Hotrod machined sheave with gold spring and Dr Pulley greaseless rollers 16grm or 18grm not 100% sure, also running on 27" bear claws tires now. The machined sheave helped a lot, but it may seem juvenile but I want to wheelie my machine. What would I need to do? I use my machine on trails, love the mud, but during the winter I put the plow on to plow my driveway. Also I don't know if this will make a lot of difference but the suspension is set on soft?

I know what you mean about the wheelie thing. There are times where it would be a hell of a lot easier if I could just wheelie over something. I still can't get mine to wheelie easily while others seems to have no problem at all. I'm thinking their secret (in addition to just being better riders) is stiffer stall springs in the wet clutch.

I've heard of guys running machined sheaves but keeping some of there factory rollers in? Where would one find stiffer stall springs for the wet clutch?

No Dean. It's called brute power.

That's what wheelies.

Brute power=200lb box on rear rack.

Looking at a few Brutes myself today

EPI sells the 1000rpm stall springs. If you are looking for 500rpm then Hauck sells them. They are $6 each plus shipping.

I will have to confirm, but I believe I have the 500's which didn't seem to make any difference at all. I'll have to find out exactly which kit the dealership installed.

Yeah, I don't think I'll be switching brands for an extra 3HP.

 

[tex78]

3 hp ????


Pardon me ......

More than 3 hp diff between the 2.

Here you go: 2013 ATV Manufacturer horsepower ratings You may find that a couple of the numbers are a little out, but this seems to be one of the more accurate/current charts I've seen.

 

[tex78]

The carbed brutes are 4-5 more hp than the fuelys. 54-55 hp if I recall.

Here's my set up on my 07 700
EPI 1000 stall springs
JBS machined primary
16g Dr. Pulley greaseless OD weights, but I run them greased
Purple secondary with anti friction washers.
K&N air filter
HMF performance or utility slip on with their optimizer.
Stock suspension set on notch 4 so a little stiff
26" mudzillas, not tall but still a heavy tire.


I like this setup over my older EPI kit I was running. Never liked using low range because it was to slow. Now I use it all the time. Much better off the line gains and with the OD weights, it tops out at around 65k, whereas before it was about 40ish. As far a wheelies go, if I got traction, I'll stand up in end and can pull the front end up still around 15k with a bit of body English. With my suspension set up stiffer, I don't get the weight transfer to help lift the front end so must rely on traction alone. One thing to watch on the grizzlies though is the rear diff. The bolts have a tendency to loosen off, egging out the holes on the frame mounts, and eventually the rear diff can twist out of the brackets.

Nice try - more like 50.2.

What exactly will installing these 1000 rpm stall springs do for my machine? Please excuse me if my question sounds noob, as I am a noob when it comes to modifying atv's.

The grizzlies run 3 clutches. The wet clutch or engagement clutch is inside the engine cases, bathed by oil. Basically operating on the same principle as an automatic clutch in the old gear bashers. Requires centrifugal force to engage. These springs go in there, raising your engagement rpm which gets you more into the powerband on take off. Then there's the belt driven clutches, but unlike a sled, the belt stays tight at all times as it does not do the engagement. Messing with springs and weights changes shift out and shims and machined sheaves alter the overall gear ratio. Others can expand on this and or correct me, but this is pretty much the basics on the grizzly system.

Well I tightened up my rear suspension, and bam! Wheelie machine!!!
