Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎
I have two 2003 Suzuki Ozark 250s, both 2-wheel drive. Last time we rode them about a year ago, the red one was not running well, didn't want to idle, backfired a lot. The green one ran fine.
Fast forward...I ordered a carb kit for both of them, thinking the red one has some trash in a jet. Both of these ATVs have had little use and I've always ran the gas out after use (put an inline cutoff valve in gas line). I pull started the red one to verify it was still running bad. It will start and idle, but as soon as you give it any throttle, it dies instantly. Give it a little choke, dies instantly. Took the carb apart and it was spotless. Went ahead and cleaned all the holes with carb cleaner and blew everything out with compressed air. All new jets, main jet holder, and needles. Put it back on and nothing changed. Starts, idles (not for a long time), but dies as soon as you give it gas. Same happens when you put the choke on. It does the same thing when I try to run it turned to prime on the petcock as it does in the on position.
Not an air filter issue. It is clean and it does the same exact thing with no filter on it.
Thought maybe there was a float issue or maybe a damaged diaphragm, so I took the carb off the green Ozark and put it on red. Started up and initially ran normal and revved for about 10 seconds and then started doing the same exact thing. Starts, idles (not for a long time), but dies as soon as you give it gas. Same happens when you put the choke on.
So...not the carb
Thought maybe vacuum petcock was bad, but there's no gas in the vacuum line going from petcock to carb and gas flows freely when on prime. I even plugged the vacuum line at both the petcock and carb end and tried to run it with valve set to prime. Gas flows freely, but does exactly the same thing. I unscrewed the screw at the bottom of the bowl and gas flows thru carb and out bowl drain line when petcock is set to prime.
So, I'm assuming petcock is good?
Checked spark plug and it wasn't fouled. Reset gap, didn't help. Will swap plugs between Ozarks tomorrow but I don't think that is it.
Anyway, that he history and now you're all caught up. Scratching my head. Valves? These were bought at same time and have had little use. Suggestions?

Well its finally happened, its time to replace the belt on my 2011 Polaris Sportsman 500 H.O. Is there anything specific i need to know before getting into it? Is there one brand of belt i should get over another? I'm still on my first Polaris and plan to keep it at least another 8 years.

Smells like gas in the oil ... Also, recently replaced belt, new BT does not have grooves on both sides, does that pose a problem? Also just bought and replaced new carburetor, never has it idled better, but give it gas and it backfires very loudly!
Ok so I have taken the front hubs apart everything is good and working fluids changed and full In 2 wheel drive the bike works great However in 4 wheel drive high I get a grinding clunking noise right near the foot pegs The universals are all brand new in the complete bike The problem just started after my last ride Sometimes I have to change the rpm to get the bike to go into gear in forward and reverse The bike doesn't make the grinding noise when I have the bike in 4 wheel driver low gear only in high gear Could the shifter need adjusting any help would be great Thanks for your time
My boot on the drive shaft came off this weekend. When I tried to put it back on it appeared to be about 2" too large. Any explanations????
Also when the boot cam off, there was oil in the boot. Is this normal???
Thanks for your help.
New to ATVing here and just got a '11 Grizz with the belt drive transmission and I've been suggested to take along an extra CVT belt along in remote rides just in case. I'm somewhat knowledgeable about where to get quality parts for cars but not so much for ATVs. Who makes the best CVT belt for my bike? Also, who makes just ok belts and who should I stay away from?
Also, I'm looking at getting a snatch block for a synthetic rope winch and wondered if the type rope determines what type of block you should get...or are all snatch blocks the same and I'm just thinking about this one too much?
