Ok, Got the Brute 750 all back together with the new seals and the 6* key installed with no leaks thank GOD!! Just a quick report of my opinion of the 6* key.

Having already installed the HL ICM, and Dyno Jet running on 27" Mudlites the power was all there. The HL ICM gave me back what I lost when I put the 27" tires on. Installing the Dyno Jet gave me superior throttle response "A Huge Difference" with this modification and I was a lot quicker off the line. It was installed using the Dyno Jet recommendations of the DJ144 in the front carb and the DJ150 in the rear carb below 3000 feet. with the clip on needle groove #4 at applications below 5000 feet. I have had no issues with this set up with stock exhaust.

After installing the 6* key I noticed an approximate 5% "SEAT OF THE PANTS" power increase on top of my other mods. Needless to say I was surprised with this outcome. This was about 30 minutes of riding time after the 6* install. I will be riding at Haspin Acres this weekend and will give you a report after a days worth of riding next week.

Installation recommendations for the do it yourself guys:

1. Buy a gasket kit, they say that the gaskets are reusable but I disagree. $24.00 so don't waste your time, get the crank cover and water pump.
2. Take your time, don’t think you can just whip through this cause it looks easy. sure Dimond G can do them in 20 min. but trust me, you cant.
3. Drain oil from the oil plug, easier.
4. Put a clamp on the radiator hose going to the water pump.
5. Remove the hose clamp from the water pump and let the antifreeze flow out.
6. Remove that main bolt under the pull starter, I used a pipe wrinch to hold it while I borke it free.
7. Remove the cover very gently to not damage any seals.
8. It is easy to remove the old key but a pain in the *** to install the new one without it falling out on you every time you try to slip sleeve back over it. Make sure you have the Key at the top to assist in this. Don’t damage the new key, it is a tight fit.
9. After it is all installed, clean the surfaces extra good with laquer thinner. Make sure you clean the rubber boot that the wires go into very well and apply some silicon around this boot. If you buy OEM replacement gaskets, no silicone is needed. Just clean it up good.
10. Install the cover very carefully not to damage any of the seals. I lifted the right side of the Brute up onto 6"x6" blocks to assist me lining up the pump shaft, unlike the first time when I damaged my seal.
11. Slide the cover on slow, grease up the seal centers to assist it sliding it on and dont force it on.
12. Once it is on, install your bolts and tighten them in opposites, not top to bottom.
13. Put on your impeller, clean up your pump surfaces and install the gasket and pump cover.
14. Refill Oil, change filter while you are at it.
15. Top off your antifreeze, refill is a pain in the ***!!
16. I let it sit for a while to let the silicon dry around the rubber wire seal to ensure no leaking.
17. Let her warm up and look for leaks. If you did it right no leaks, if you damaged a seal in the water pump oil will be leaking from the hose that comes out of the bottom of the water pump. I learned the hard way@!

This is not recommended installation from Diamond G. This is what I learned by doing it two times after damaging a seal. Learn from my mistake and take your time!!!!

I hope this helps any of you do it yourself guys out there. Any questions feel free to e-mail me. I may have missed something but am sure it is all there. To the experts, if something is missing please add it.

A standard wheel puller from Auto Zone will work, just reinstall your bolt so the wheel puller does not go into the shaft and split it, it is not the same size.

Great write-up killzoneq2!!!!!!!! I have a V and not a Brute Force but I'm sure a lot of your write-up and tips will help me when/if I do this mod. Thanks again!!!!!!

 

What is this mod and what does it do?

 

It advances the timing 6*

 

what is a 6 *? what is the advantage it gives, do i need it??

 

This mod puts in a offset key so it will advance the ignition timing 6 degrees. By doing this it will start the burn some earlier and give better throttle responce and a snappier quad. The down side is you "might" have to burn a better quality of gasoline.
Do you need it? I can't answer that. I might do it at a latter time. I have to make up and get my 3 stage pipe on first.

 

I'll stick with my stock machine . I've had it up to 89 mph even though I had noreason to go that fast . The Kawi BF 750 is the most intense ,most powerfull 4x4 you can find on the market. F**k the popo 800 it's only 10 more cc than the BF. the popo is almost 100lbs heavier. If you want a farm vehicle get the popo 800, If you want great 4x4 fun do yourself a treat and get the Brute Force!

 

what did you do to your brute to mske it go 89mph , not dissing but if stock thats a little crazy

 

Sorry hit the wrong key last night I meant 79mph All stock this machine is a beast

 

will this mod work on my 700pr.
and if so will i need to do the other mods you mentioned to benefit from it.
thanks.
