2008 service manual anyone?

Hello, I’m asking if anyone can help me get a service manual for my new to me ATV?

the owner slip says its a YFM450FWAN but I only know it as a Kodiak 450 2008.

Again if anyone can help that would be amazing as I’m trying to fix what is wrong with it when I got it!

Thank you

Lean running 2014’s?

It is the general consensus here that all 2014 grizzly’s, are lean at cruise. I do not doubt the tests by EHS racing, or that the problem does exist. However, I have two problems with this.
First, we have three 2014s in our group. Two 700s and one 550. Only the one 700 has a lean reaction to the throttle and the spark plug definitely shows it to be lean . The other two, run great and display good plug readings.
I know that this is not a great test. (Wish I had a dyno) But there is a world of difference between the bikes in performance.
Second, It’s a little hard to believe that Yamaha would Produce something that is close to engine failure under the right conditions and especially with airflow modifications.
As far as having to pass emission standards, The lean mixtures will reduce CO but will raise NOX considerably and could raise HC to unacceptable levels with a small lean misfire.
My question is. How many of you out there “don’t have a lean condition” in your 2014s?

2014 Grizzly throttle response

I have a 2014 grizzly 550 with 22 hours on it. Did an oil change recently. When I ease into the throttle it’s fine, but if I give it alot of gas it sounds like it wants to stall. Is this normal? What should I listen for when it’s running to know if the valves need adjusted? I’m really trying to avoid a trip to the dealer

is a 550 grizzly powerful enough for 2 riders?

Hey guys, I’m looking again and I found a 2010 550 efi w/ 80 hrs for about $5k. First off is that a good price?

Secondly, is it powerful enough for 2 riders? I weigh about 190 my gf weighs about 105. We’ve rode 2-up on a honda rancher 420 before and it was perfectly fine. I’m assuming this would be too?

Thanks!

About to take my Grizz in a diff direction..

I purchased my 04 660 new on dec 31, 2003. With roughly 30 miles on it I installed 27×10 and 27×12 mud lights on the stock wheels. I used it for reg trail riding and always loved finding mud holes that other people couldnt go through and giving it a shot on the grizz.

In 2007 I fabbed up some tranny snorkels for it and begun to mud it even more. In 2008 I added an hmf exhaust and pro design filter and some new wheels, and the mudding continued.

In 2010 I started riding at a new place that had mudholes like id never seen. It tested the grizz and my own riding ability more than ever. Often times it took me off the machine pushing and working the bars to make it through without a pull. My passion for mud riding had grown to an all new level. And people seemed to flock around a hole when I was about to get into it. I was fastly finding out my current tire and setup had found its limits, and I wanted more..

Early 2011 I ordered a lift, and some new wheels with 30" Zillas and continued my mud crazed outings with new found passion. The Grizz was a beast! It had mustered up a cult like following around here, and was the standard of badass and capability in the rough in everyones eyes. But this all came at a price..

I went through multiple wheel bearings (which I expected), rebuilt the front and rear diffs, broke a few front axles, replaced the rear axles cause the stockers just couldnt handle the angle with the lift and the boots tore pretty quick. Always had to take a change of clothes and shower off before heading home, and take the hose to my clothes before even considering putting them in the washer. Not to mention the cleaning of the grizz itself.

The last 1 1/2 years Ive started attempting to avoid mud holes if at all possible. I go through reg stuff, Im talking about those holes that swalllow u up, that u generally can go around. Every blue moon Ive had a few and felt froggy and got off in one just to prove its still got it to some on lookers. And for the most part, Ive really enjoyed just RIDING, and staying cleaner, parts lasting, and not having to spend hrs cleaning my machine off.

Here’s the deal. The setup while it looks so in your face intimidating, sucks in handling. Those zillas have a soft sidewall, couple that with 30" height and talk about sidewall flex, front end push and body roll! Also the lift made the rear end much stiffer. Even with the shocks as soft as they go its too stiff unless I have my big cooler and a passenger. The times I have picked up the pace and rode it fast the handling is so horrible. So I believe the time has come to pull off the lift, sell the 30s, and get a set of 26" original Big Horns on my 14" SS108s. Ive been looking at pics and checking prices for weeks. Ive had this idea in my mind for around a year, just hadnt been this set on it til I went on a ride a few weeks ago. I found myself hating the handling and how the open tread pattern sucked on the rocky terrain with lots of hard pack, and imagining how much better the big horns in tread design and height, coupled with removing the lift would change the ride and handling of the grizz and take it to a level Ive never even experienced since its always had larger mud type tires on it. I’ll miss knowing I can go through most holes around here, and being the dominant machine in that capability dept compared to all my riding buds and people we usually run into, but I think I’ll enjoy riding much more in every way besides pure mud riding, which Ive been trying to avoid anyhow.

So that was a long read but anyone that wants to discuss, ask questions, give input, share their feelings or experiences when going totally diff directions, feel free!

If I can post pics with my phone I’ll prolly add some. Dont feel like hosting em just to do so.

Snorkel failure

So after I swamped my grizz last year,I ordered a kit from snorkel my atv. I have to say I am not happy. It has issues including having a 45 in stead of a 90 in one spot. Now my tire hits the tube. But that’s just a small problem. I followed everything to the tee and it seems there is a leak.
Don’t even know where to start to try and fix it.

This site has really messed me up!!!

As the title says, and I will explain. I was perfectly happy with my Grizzly off the showroom floor, but after becoming a member on this site it has caused me to dig DEEP in my pockets. Spend countless hours in the shop without dinner. I’ve come to a point were I’m thinking I may need to put a trolling motor battery in my box so I can supply so much more. It’s caused me to think way outside the box on some situations and I’m an electrical engineer. I freakin love it too :peace: Ya’ll was expecting something bad huh :icon_ laughup::icon_ laughup: You see what I’m doing at 3:30 in the morning :rocker:
