Okay so I need a little help

just picked up a brand new 2012 yfz450 carb model

being that it was a left over I thought my cutting out issue was bad fuel

but even after draining the tank and putting fresh gas in it

after riding for about 20-30 min in the trails

if I hit the throttle wide open it cuts out bad (doesn't die though)

it won't even climb hills

and the one time it was so bad my buddy beat me on a stock 300ex

my yfz is completely stock

no mods at all and I have tried taking it back to dealer

but since it mainly is after some trail riding

they can not replicate the problem

someone plz help

I've only been able to ride this for one tank

of gas being its running like chit and have to turn home at big hills my buddys chit quads climb right up

I had the same issue and took it to the dealer multiple times and they also couldn't replicate the issue. The solution I found was to take off the Air Box cover...the issue is that there isn't enough air. If that works then you can purchse a different filter like a bolt on one that doesn't require the air box cover. I can find the one I got and if that helps, but try to take the air box cover off and see if that does the trick. Good luck!

      Hi all. I have a timberwolf 250 2nd that will not start.. I thought it was out of time bc the guy I got it from said it just quit on him. The tensioner had a nut welded to it and it was like2 teeth off. I installed new tensioner and chain and it still will not start. It has fire and it will not hit off brake cleaner. It has compression. Haven't put a gauge but I'm sure it will crank and run with what it has. I double checked my work and it's still in time. Spot on. Both valves move. I'm about to put a feeler gauge on them and I'll cone back but other than that any ideas?

      Mud riding is one of the most popular forms of ATV riding, but the wrong tires can leave you stuck fast in deep ruts and swampy trails. Choosing the best ATV tires for mud can dramatically improve traction, steering control, flotation, and overall off-road performance.
      Whether you ride trails, mud parks, swamps, or backwoods terrain, this guide covers some of the top ATV mud tires available today and what makes them stand out.
      What Makes a Good Mud ATV Tire?
      Mud tires are designed with aggressive tread patterns and deep lugs that help clean out thick mud while maintaining traction. The best mud tires usually feature:
      Deep tread lugs Wide spacing for self-cleaning Strong sidewalls Taller tire sizes for added clearance Durable construction for rough terrain 1. Maxxis Zilla

      The Maxxis Zilla is one of the most popular ATV mud tires because it balances mud performance with trail comfort. It is lightweight, aggressive, and performs well in a variety of terrain conditions.
      Why Riders Like It
      Excellent mud clean-out Lightweight design Smooth trail ride Available in many ATV sizes Best For: Trail riders who also spend time in mud.
      2. ITP Cryptid

      The ITP Cryptid is designed for serious mud riding with deep tread lugs and strong sidewall construction. It provides excellent traction in deep mud while remaining durable on rough trails.
      Features
      Deep aggressive tread 6-ply durability Strong side bite traction Great for lifted ATVs Best For: Deep mud and swamp riding.
      3. Outlaw 2 ATV Tires

      The Outlaw 2 has become a favorite among hardcore mud riders thanks to its massive lugs and impressive pulling power in thick mud.
      Pros
      Extreme mud traction Large tread design Excellent forward bite Popular in mud parks Cons
      Rougher ride on trails Heavier than trail-oriented tires Best For: Dedicated mud machines and mud bogs.
      4. STI Out & Back Max

      The STI Out & Back Max offers a solid balance between aggressive mud performance and everyday trail comfort.
      Highlights
      Durable sidewalls Great traction in loose terrain Smooth handling Long tread life Best For: Utility ATVs and hunting machines.
      5. SuperATV Assassinator

      The Assassinator is built for extreme mud riding and features huge paddle-style lugs capable of digging through the nastiest swamp conditions.
      Features
      Massive tread depths Extreme mud traction Available in oversized setups Designed for hardcore mud riders Best For: Extreme mud builds and dedicated swamp riders.
      Choosing the Right Mud Tire Size
      25-27 Inch Tires
      Great for stock ATVs Less drivetrain strain Better acceleration 28-30 Inch Tires
      Balanced performance More ground clearance Popular for trail mud riding 32+ Inch Tires
      Maximum mud performance Best for lifted ATVs Ideal for deep swamp riding Larger tires may require clutch upgrades, lift kits, or gear reductions depending on your ATV.
      Bias vs Radial Mud Tires
      Bias Ply Tires
      Stronger sidewalls Better puncture resistance Popular for aggressive mud riding Radial Tires
      Smoother ride quality Improved handling Better trail comfort Most serious mud riders prefer bias-ply tires because of their durability in harsh terrain.
      ATV Mud Tire Maintenance Tips
      Wash mud off after every ride Check tire pressure regularly Inspect sidewalls for damage Rotate tires periodically Avoid excessive pavement riding Lower tire pressure can improve mud traction, but beadlock wheels are recommended for very low PSI setups.
      Final Thoughts
      The best ATV tires for mud depend on your riding style and terrain conditions. Riders who split time between trails and mud often prefer versatile tires like the Maxxis Zilla, while hardcore mud riders typically choose aggressive options like the Outlaw 2 or Assassinator.
      Before upgrading to oversized mud tires, make sure your ATV can handle the added weight and drivetrain stress. Proper setup can dramatically improve your ATV’s performance in deep mud and swamp terrain.

      Background,
      This winter (Dec.) I was plowing and everything just died, just quit.  No lights, no pull start, No nothing.  I've had this problem before and I changed the voltage reg and it ran fine for over a year. Then this.  So I changed it again, thinking this was the same problem.  Tried to start it and a small pin hole in the CDI appeared with electrical smoke.  
      Months go by and I finally decide to just replace parts (I'm Horrible at electrical issues).  I changed the stator, new CDI, new Voltage reg, new starter solenoid, tested the starter (prefect), charged the battery.  
      Went to start it and the solenoid rapidly clicked.  All the dash lights on, headlights work.  Pull stared it and it fired right up no issues.  Looked into the rapidly clicking starter solenoid and it was not enough juice in the battery.  Took the battery completely out and hooked up a jump box to it turned the key, light on, everything looks good.  Pushed the starter button and it fired right up ran great.  Turned it off to test it again, Turned the key and nothing.  No dash lights nothing.  Took the jump box off and pulled started it.  Started it right up.  Re-hooked the jump box, still nothing.
      Any Ideas?

      As the title says, I've got a crankcase full of fuel / oil to deal with and figure I'll just start from the top and move through the system.  Going to start with a rebuild of the petcock and then the carb if the problem isn't fixed with the petcock rebuild.  I figure I'll go with a Moose kit unless others with experience recommend another brand (All Balls, etc.)
      Any suggestions?  Thanks in advance.
