YFM400 Carburetor Carb Kit Compatible with Yamaha Big Bear wolverine Kodiak Grizzly 400 YFM 400 YFM400 2000 2001 2002 2003 2004 2005 2006 ATV With Air Fiter Fuel Filter, By Liyyoo

This product worked as a bolt on, only had to turn the idle screw half a turn to raise the idle. Runs great and the air filter actually fits even though it needs a good deal of stretching to fit. Very pleased with this product. One year later it still works well.

I installed the carburetor on a 2002 Big Bear 400 used the fuel filter and clamps supplied, hardest part was to get the throttle cable clip back into it's place, I used the choke valve suppled it had a machined fit so there was no O-ring to go bad like the original. I didn't change any jets like multiple people had suggested in reviews I read prior to purchasing the carb and I didn't make any adjustments to the low speed idle jet adjuster, I did adjust the idle adjuster that is on the cable, my ATV now runs and idles smooth, choke works well and with the fuel filter installed I'm confident no more contamination will get to the jets in the new carb, excellent price, great product

Carburetor was fine the air filter will not work the fuel filter and the rest of the items are good

After our nephew sank the four wheeler in mud we had to replace the carb. Quickly shipped. Good deal.

Easy to install 7 weeks ago and it worked for the first 6 1/2 weeks and then started to leak gas through the carburetor into the cylinder head which made it down into the oil pan. Now it’s going to cost me $250 minimum to rebuild original carburetor and change oil and filter and buy another new air filter. Very unhappy I bought this product as return window expired 2 weeks ago. The one star is for the easy installment and I couldn’t give it 0 stars for performance.

Exact fit replacement

Would have been if I was able to go full throttle out of the box but I can’t, it just Boggs down and dies, need to adjust it now.

Wonderful Carb! Works Great! Installed and only had to adjust the Idle.

Worked for a month then leaked fuel

Same complaint as everyone else, tried everything possible with this carb and it’s impossible to remove the bogginess from this carb, putting the old carb back on.. What a waste of money.
