I have a 2004 grizzly 660. I've been interested in doing some mods. Wanted to get into the types you see at mud bogs. Lifts and big wheels and tires. Nothing extreme. But Definitely higher and bigger. I'll also be doing radiator relocation and probably a snorkel system. What all am I getting into with the lift and bigger wheels? Any differential mods? Wheel spacers? Clutch changes? Any and all recommendations would be great. What brands and parts you recommend. What sizes you would recommend. Any other mods. Definitely want to do it right and not have it breaking constantly. Thank you.

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.
