Looking to do mods

Welcome from Colorado.
If you don't want it breaking all the time, don't do a lift, radiator relocate or snorkel set-up unless you are very good at tuning.
As for clutches, there isn't much to do with the wet-clutch.
But you can do a lot with the drive pulleys.
I guess it depends on higher, but not much higher and wider but not much of that either. I installed taller tires that raised the grizz a little, then rolled the rear yokes for another 3/4" in the rear, and as for wider I keep the tires under the fenders, but spacers will make it wider. We have 50" gates around here so wider can really suck.
Lift it up and plan on all new axles if you ride hard.
If you change the air intake diameter on a carbed bike then plan on re-tuning, that is after you get it perfectly sealed and keep the new tubing from leaking water and air to then learn you can take it back apart again to change a jet, then seal it all back up to determine if you installed the right jet.
By the way, what is our mod budget, over 5k or under? We are great with O.P.M.

Probably under 5k. I'm knew to this as you can tell. I've always just rode stock ATVs but I always saw others doing mods and their ATVs do better. So would like to learn how to do them. Didn't know there was that much into it with rad relocations. But ya. Most likely under 5k. I was told by tireshop I couldn't put bigger tires on stock rims but they wouldn't help me with getting new rims as for what what size I should get.

The tire shop $hit, you don't need new wheels. Look at my signature for things to mod that don't screw up a good bike. I have bigger tires on stock wheels so the guy at the tire shop trying to screw you. He is not as good reference and you can tell him I said this.
The deal is the Grizz is not the best machine for deep peanut butter mud which does require big mods. I'm not into thinking a mud Grizz looks tough, but others do so pick your side, where I live is a different riding situation, so if all I had was to ride the same mud hole 100 times a day my Grizz might look different.....actually not 40 years ago Iived near the $hit hole of the world and mud hole riding was the big deal, so I moved
Here is a picture of my Grizz, not much taller but this thing will do 95% of what all A.T.V.'s can do. It runs between 3000ft. and 14,000ft. regularly each year from deserts to high mountains which is what the Grizz is designed for.
I hadn't found this picture in years, a very dear friend wanted me to ride her around the area mountains on the A.T.V., she has a nice jeep and runs these mountains regularly but wanted to see what the A.V.T. ride experience is all about. I took her 50 miles out from the nearest town, but not through deep mud; here we are near 13,000ft.

Most here know for deep mud get a canned ham, the grizzly will be lacking power after you spend $10,000 to build one right, the wet-clutch in a grizzly won't take the power of a 5mm stroked crank for long, but long enough to break the transmission. We know this from past member experience, its too bad once they destroyed their grizz they no longer post here anymore.
