Hi all, new to this forum so thanks in advance for the help.
I have recently brought a 2013 power steering fuel injected foreman 500.
It has a crack in the front casing and was running rough. I have since replaced the front engine casing and this has made no difference to the engine performance.
It starts and idles but bogs down and starts to die once throttle is applied.
It maybe be but it also sounds very load.
I have uploaded a video link of it.
We are starting this topic so that members can share their view about ATVs; what they are used for, types, etc. This topic is intended to help new members and visitors and generally those that don't know much about ATVs and would like to learn. So anything you can add to this topic that you feel would benefit a new comer, please add a reply..
Below is a quote from a response to similar question from yesterday:
"Easiest thing to check is trash in the main jet. if it idles fine, then the idle circuit and low speed jet is clear. if it bogs off idle that's when it's transitioning to the main jet."
I will go ahead and open up the carb and check the main jet, but please respond to this post as if the main jet is squeaky clean.
Below is my post:
Only starts and runs on Full chock.
Does not matter what position I have my "mixture" screw. Tried it at zero, 1 turn, 2 turn, up to five turns. Spent a few hours confirming that the position of the mixture screw does not resolve issue.
Runs great at idle and if I slowly engage throttle, it will rev up as expected. But, quick rev up or when I am trying to drive it, it spits and sputters and looses power.
I also use a propane bottle and did not find any obvious leaks, and the vacuum port is hooked to fuel peacock and I also made sure to simply block the port with my finger to see if that would resolve the issue.
New Carb (after market), New Coil, Fresh Gas. No leaks at manifold boot, hot battery. Good gas flow. Runs too good to be a valve issue, or cylinder, great compression.
I can move the choke out a tiny bit, and it will still run, but will still bog down when I try to power it up.
I also have a 250 trail boss Polaris that I require to run at full choke, but it has power at all throttle potions.
I suspect it is running rich as the choke is on, but will not run with it off.
Any details would be appreciated.
Ok so 2000 sportsman new.caltric carb new fuel pump new jug and piston new cdi and coil finally get to start it and itll idep for 5 to 10 seconds and die what am i missing people any help id love ya forever lol

Hey fellas. So I have a 2012 yfz450r. I work on the road for a living and went to a job and let a friend of mine borrow my wheeler while I was gone. Well, we know how that all turns out. I come home and it’s not running. Swears up and down he just went out to start it one day and wouldn’t start. Well, I start fooling with it and figure out the fuel pump is bad. I replaced the pump a couple days ago and brand new battery. When I go to start it, the engine light blinks every time I hit the start button. So, I decided to try and pull start it. It’ll turn over strong and half-ass run until I pull in the clutch and dies. Then the fuel light came on. I can hear the pump turning on and doing it’s job. Now, when I turn on the key the fuel light stays on, and same deal with engine light blinking every time I hit the start button. Can anyone help me out at all? This has been a NIGHTMARE. Super appreciative for any help. Thanks.
