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

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

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.

This was replaced in a Yamaha grizzly. Other than the fuel screw which needed to be screwed out 2.5 turns it helps the quad run great. Fitment was perfect, price was right, decent quality.

Great delivery time and perfect fit

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.

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

I installed this on a '02 Yamaha 660 Grizzly ATV.The good: The Grizzly runs just OK with this carb and it did fit with no issues.The bad: There is a bit of a dead spot in the acceleration curve at the lower RPMs. It leaks gas all over the place due to the float not having been adjusted properly at the factory. The little triangular cover over the throttle cable assy was not drilled out quite right and had to be forced to fit.A Mikuni this is most certainly not. I am not going to say the usual "it works good 'for the money'" because I don't care if it was 10 cents or 700 dollars, it DOES NOT work as it should. Being cheap is no excuse.I can afford a new or rebuilt Mikuni but many cannot. People should be able to buy a cheaper carb that works as advertised. This is a cheap carb and works like a cheap carb - not well. Maybe some of the other cheap carbs are OK, but I am not buying any more to see. I will rebuild and reinstall the Mikuni, which will work perfectly and not leak gas all over the garage floor. I thought I would try to save a few bucks, apparently I never learn.

Thank You!! It took my husband 3 hrs to replace the carburetor. I have not been able to ride the 4 Wheeler for 2 yrs! It idles and runs great. It's a 2003 Yamaha Grizzly 660. Runs like a new one.
