Actually, i havent checked that yet, I will now though, keep any tips coming cause she still aint runnin, well runnin right anyway.

 

I have a yamaha warrior and im not that good on utilities. But does ur atv have a parking brake. Because I had a simalir problem and i found out that it was the parking brake wasnt the whole way off. And when the brake isnt the whole way of on my atv it doesnt allow the engine to run right. Also make sure that the main parking brake box isnt streched from the cable

 

i checked the parking brake because i thought that it might be the problem but it wasnt. My Warrior Did the same thing your describing so i thought to try it as well. thanks for the idea though..

 

Have you ever adjusted the valves ?? One of the causes for hard starting is when the valves are to tight and Yamahas valves tighten over time instead of loosen.

 

Something else to check.... It may have nothing to do with your problem but it should be a regular maintenance item for BigBear owners.
My 2000 BigBear has been reliable for me except for water getting into the choke plunger. I think water either gets around the plastic nut holding it in or runs down the cable, either way it will cause the choke to stick causing hard starting and rough running. The first time I took the plunger out it was stuck bad enough to need lots of penetrant and vise grips. It also rusted the spring bad enough that I had to replace it.

Its worth looking at whether it fixes your problem or not.

Good Luck

 

Same Excat thing happend to me on the recon i fixed it by draining the carb, putting in fresh gas, and adjusted the float bowl a lil and it was good as new!

 

Problem solved!!! I took the fuel heater fuse out from the fuse box and its runs great now. I have a new problem now though, It wont start in gear anymore and the brake light comes and goes. I just have no luck with electronics.

 

You have a bad connection w/ the light, my guess

 

if your tank ad carb are gravity fed (no fuel pump) than u might wana lookat the gas cap tube if that gets kinked it creates suction causing the gas not to flow properly but idunno wouldnt hurt to check it

 

my bigbear never started in gear..only when you pullstart it
