YFM350 Carburetor w/Intake Manifold for Yamaha Big Bear Warrior Wolverine Moto-4 YFM 350 Yfm350 ATV Quad 1987-1998

Inherited a wolvy that had been sitting for approximately 6 years. Existing Mikuni carb was too far gone (gaskets dried, boots cracked, ethanol gas gunked up). I fought the Mikuni for 11.5 rounds (carb cleaning, rebuild kit, automotive parts cleaner soak, etc). I finally gave up & I went to the locker room & ordered this Mikuni clone. I had to tap the hole where throttle cable bracket is held to the carb body because there were no threads in the hole & had to modify the throttle cable tube where is goes into the carb body. The factory tube is too long, doesn’t allow enough cable to connect to throttle arm inside carb body & I didn’t want to have to spend more $ for a longer throttle cable. After 30 mins of modifying, I Installed clone & wolvy fired right Not a single fuel/air adjustment needed. The only adjustment that I had to make was the throttle cable at the handle bar perch. The mods aren’t difficult to do if needed. I only use the wolvy for scouting & hunting so I don’t need a high performance carb. Sure the clone may slightly underperform compared to a true Mikuni. But, Mikuni price is 4-5 times the cost. I’m very pleased with the performance of the clone. I’d recommend to a friend.

Ok, so we all know we get what we pay for right, this is a very cheap carburator. With that said, this little bastard is working great! I had very low expectations, but so far so good. How do they make any money selling these so cheap? The original carb has now been cleaned and ready to reinstall, but I am just going to keep running this one till she dies.

The good: wow. Just wow. No adjustment needed for my machine. Installed in about 20 minutes, filled with fuel and fired right up. Rode like madd two weekends straight now. Perfect replacement. Would buy again.The bad: Did 4 stars because the manifold was unusable. So poorly machined it barely mated up to the head and there was no way to bolt the carb on after. If you’re excited about this cause you have a damaged manifold, beware. You MAY get lucky but on my 1999 Warrior there was no way.As I said before, I would buy this again. Great product, superfast shipping.

The stock mikuni carb on my 1988 moto 4 Yamaha 350 was a dual cable carb. I used the cable that went to the slide for the new carb. The other cable was for the butterfly I just tied off and tucked away under the 4 wheeler. The adjustment from factory was right on. The install was fairly easy. I liked the extra screws and jets supplied along with fuel filter.The only complaint is the intake manifold does not fit. The original is about 2 inches longer. I will have to buy another one for $15. I would recommend this product.

I got this carb as a time-saver instead of taking my old carb apart *again*.This new carb probably used more time than taking the old one apart.First the intake manifold sucks and mounting nuts will NEVER fit on it without serious modification.Second, the throttle cable tube was bent at the wrong angle and like some other reviewers required a blow torch and careful bending, then I cut off the threads.Last, the accelerator pump either sucks or doesn't work, flicking the throttle from idle stalls my quad. Maybe it needs to be worn-in, but again just another indicator that I should have just cleaned out my old carb in the first place.There's a bunch of other small problems, supplied nuts are larger than 13mm but way smaller than 14mm (factory nuts are 12mm, another reason why hardware won't fit on the intake). The supplied jets aren't labeled, I have a bag of two extra, no idea of they are spares or different sizes.

Product said it would fit my yahama big bear ymf350 but didn't, I had to use the old boot to connect to head because the old one was to short also they did not tap hole for the throttle bracket to attach I broke off my tap in the hole trying to do it myself and cable guide tube was a half inch longer so i had to cut some off, that being said when I finally got it to fit the carb itself works great.

not the best replacement, but fine for the price.

My 4 wheeler is running like a champ and it’s a 1987 Yamaha.. this carburetor did the trick
