Hello and thanks in advance for any help. To start with this is an 08 420fm. So I got this with a broken timing adjuster. Replaced adjuster and timing chain. I’m certain the timing is correct. I also replaced the fuel filter and spark plug and air filter. The problem is when riding, up to about half throttle it runs and idles great. Over half throttle it starts to stumble, and at full throttle it falls on its face and starts smoking(burning oil) blue smoke. Anyone have this happen to them. Any help is greatly appreciated!!!

Don’t put away those ATV’s yet! This is the last run before the bucks run!

Tug Hill Buck Run – Last Run Before the Bucks Run

Saturday 9/24/16

First prize is $1,000.00

Drawing at the Montague Inn between 4 – 6 pm. Live music, food, and FUN!

We’ve got a half dozen in our group so far, probably will end up with the usual dirty dozen! Fun ride, great temps. Went on this one last year and it was a great time, looking forward to a fun ride again this year!

Don’t be shy, there’s plenty of room on the hill and navigation is a breeze!!

Well ,,, we all know what happens when you borrow something out…

Long story short: Borrowed Grizzly 400 to Wifes brother , stick into radiator hose on bottom of machine , not noticed as it was in a river when happened. Take up north , borrow to same brother in law , he drives it 14 miles with NO coolent.

Even though he was in front of me , and we stopped SEVERAL times ,, he waited until it was NUCLEAR hot , and would not move anymore to ask me ,
"What does this RED light mean ?"

I shut it off immediately , asked how long has it been on ?
He says , at least the last 10-15 mins.

Motor is cooked , rings gone I’m sure , who knows what else might be junk. It was so hot his nuts must have been melting.. WOW , and what do you do …. He says to me
" good thing I told you hey"

It’s a little f#cking late now I said… lol… Family , what can you do..

So , anyone have any experience with a rebuild on a 400 ?
any advice ?

Planning on rebuilding it ,, sure it needs a piston , rings , and lots of new seals. Going to go .50mm over.
Hopefully head is not warped , and cylinder is not cracked , if they are ,, cost about $600 each pc..

Any advice appreciated.

My Sportsman just clicked 5,200 Miles last weekend while riding in the Black Hills. Besides the glowing exhaust issues and melting plastics, which were fixed once I went to the HMF Exhaust, this machine has been pretty much trouble free. Original wheel bearings, original ball joints, and only a few of the bushings have needed replacing. But over the weekend, this happened:

I was coming up over the top of a hill, and when I got over the crest, it dropped off sooner than expected. I think the hard landing in combination with the extra weight up front from the gear and rotopax’s I was carrying took out the spring. Was able to get it back to the trailer, and luckily this happened during our last hour of riding.

I have to say, this machine has seen a lot of hard riding once the exhaust issues were fixed, so I’m impressed with how it’s held up.

I would recommend checking your springs and retainers if you’re getting up there in miles – it seems like maybe the springs get fatigued over time.

hi to all,

Thanks.

Redid my setup with SYA. Turned out great. Went with the same place instead of side. I moved everything up bc I keep hitting them. I love them and the look. The slide together! Not finished but just FYI..

Try to post pics but gave me some gay ass post count bullshit!

Hello all!

I just picked up a 2005 scrambler 500 4×4 and I noticed real quick that is needs new rear carrier bearings. I went ahead and picked up a new set of bearings/ seals.

I would really really like to know if any has a "how to" for the rear bearings or someone can simply relay a step by step process to get the axle out and the new bearings in.

Thank you all!

I am in a loss for words to describe my experience with my brand new triple black Can Am! After spending some time adjusting the preload settings, I was wheeling and jumping my bike all day long in the mountain trails. This bike has handled everything I’ve thrown at it effortlessly. This literally is the most fun you can have with your clothes on! I will say I can ride wearing shorts without burning my leg now. My wife’s 570 is terrible to ride due to the heat so this was a very welcomed improvement.

The power is super addicting and plentiful especially after riding a 570 outlander. I would highly recommend this quad to any atv enthusiast.

Dealer has a 2008 Polaris Sportsman 800 with a warn winch and blade. 415 miles, 88 hours. Asking $5200, is that a little high for the year? Pics look good.

So just bought 2017 mrx1000 last month…after my first weekend ride up in N.H. im not sure this quad is for me ugh! I traded in a 2013 xtp shorty with 4500 miles which i loved no complaints except for the squeeks and clunks lol you all been there. So heres my problem… i ride 2up with my wife at least half the time so got the long wheelbase and a 2 up seat but the ride is so rough she’s halving a terrible time hanging on. I no get a new wife hahaha! Not going to happen i enjoy her company on the trail to much. So did i mess up and just need to bite the bullet and by a max with the long travel fox’s or is there any hope? Also ran dry with only 67 miles on first tank. Used to go 90 to 100 two up on the same trails with my old xtp.
