Would there be any real problem running 27s on the front and 28s on the rear? I want the 28s in back to give a little more clearance, and 27s on the front to keep the CV axles together.
Opinions?

The final gearing would be off a bit. It wouldn't really matter in 2wd, but in 4wd the rears would be pushing the fronts. I guess it would really matter in mud, and you really don't need 4wd on our trails.

I think I am talking in circles.

Just don't put it in 4wd on hard pack, that would be pretty hard on the axles. As hard as we use the 4wd you would probably be alright with 28's all the way around. That is what I am going to step up to when I chew these up. It would just be more flotation in the front.

I think you'd be better off running 28 all around than run diff sizes in the ft and rear.It'll throw off the gear ratio in the diffs and you'll poss have different ft and rear drive shaft speeds due to the height.I ran 28 Zilla's with a lift on my old foreman and never broke any axles,IT'S A HONDA!!!

Just don't try to yank the wheels back and forth in a hole and you probably won't have axle problems. I have had good luck with my 28 zillas. They pull me through more than my mudlights ever thought about doing.
Has hondak broke the grizz yet. A buddy of mine has a 05 grizz. he has broke three axles in the last 4 months. I don't know why I go through the same stuff that he does. Maybe it's the locker. dunno

I had a 2003 Grizzly with 26 Gators and I broke 3 ft axles,broke a rr axle and blew out the seal.It always overheated,and it had a recall for fuel boiling/overheat deal,they rejetted it,put a heat shield under the gas tank,put new side panels to cool down engine.It didn't fix a thing,then I bent 2 lower control arms in the ft from tiny cypress knee's.After all of that I then broke the ft inner joint on the drive shaft,that caused the seal to leak and it then stripped the splines inside the engine.In 8 months of owning that 660,it was in the shop for 5 and half months.I sold that and bought the 04 450ES and ran 28 Mudzilla's with a lift kit and had progressive lift shocks at the same time and never broke 1 thing in a years time.MY 2 buddies still have there's and are still breaking Gorrilla axles in the rear and always clogg up the radiator and clutch baskets for the belt,they're running 27 Bi and Tri Claws.Yamaha makes excellent engines but the drivetrain can't handle it.I personally would't rec the Grizzly to anyone that rides in water and mud climates(MY OPINOIN ONLY)...

I do though miss the power of the Grizzly sometimes.I think they fixed the axle problem's from what i heard.The first two years of production they cut corners on expense in the metal area.That was directly out of Yamaha's mouth.They do haul a#$ though,even with 27's!!!

I don't think that they fixed them. My buddy is on his 3 broke axle in the last four months.

I am not knocking the grizz at all. they have awesome power. If I ever buy a belt drive bike it will probably be a grizz. OR the new bomb.

Either am I on knocking the Grizzly.I just want to inform everyone on a big issue on the bike.Right now my 2 buddies are breaking Gorrila axles with 27 bi and tri claws.If the rears don't break they always pop out and dump gear oil everywhere and ruin the seal.They had constant oh problems with the radiator,starter relays failing,diff lock solenoids failing,clogged up clutch springs for the belts,pull start cords breaking,fuel vapor/boiling in tank(bogging in mud) and on and on. The #'s don't lye when all 3 of us had the same problems with the same bikes...

hey ray before you buy gorillaz let me know we can go talk to my axle guy i know he can make something better for cheaper. i think they pop out is because there not long enough when the angle gets bad.

Gorrila told us they had a bad problem with the rear axle c-clips being to small and they didn't use o-rings at the base of the inner joint splines.This was due to the axles popping out in the rear diff...
