Bolted on and rode away

Used carb & aircleaner tuned easy

I've had this for a while, was very apprehensive to 'do' this operation;lol, two bolts off , two bolts on, kick and go. (bike was still warm from earlier)Well I did watch a few videos over the last two months, otherwise forget it.Turn FUEL OFF, remove fuel hose, air filter, take off two mnting bolts,(I didn't need new gaskets nor need to remove riser stem, still perfect)pull carb slightly halfway out of area, unscrew top cap , compress long spring sothe cable end can come out.the long slot of the internal slider thing that houses the cable, spring and needlegoes to only one way , so you can't really mess it up , don't force anything it shouldgo in and or out very easy. remove old carb, put new one on in reverse of taking old oneoff, ; feed cable back through top cap, and spring.This part is tricky left hand has to hold cap , spring cable, compress the spring andhold with left hand, grab cable end with right hand , pull it tight till it can be pulledlonger than the 'slider' length , fix it into the keeper hole, the one you['d removed thecable from to begin with.slide assembly into new carb, screw down cap.Put main bolts back in, snug, add air filter, fuel line back on, fuel valve on.Kick or push electric start , should start right up.Tool notes for 140cc pit bike; 8mm socket and open end, 10mm socket and open endand hand driver for both if you have them. I removed the spark plug wire to accesspassenger or rt side of bike to get one of the two 10mm main bolts out.Kick the tire one way or the other to get the fender out of the way so youcan us a hand driver to remove the bolts.This is the same carb as the oem as best I can tell, but my oem had had a ton ofhours on it so the bike was running poorly, this replacement was a night andday improvement.There's a fuel mix on the bottom , the default setting should be ok...I suggest replacing that screw before installing carb with an aftermarketfuel mix srew, they are longer and extend out with a 4 paddle numberedthumb, easy adjust end.The side adjust that they call air mix, is also called idle adjust , seems thatmost people tell us that if you need to adjust , screw it all the way in verygently so you don't damage it, and back out 1.5 to two revolutions/turns.Same pretty much goes for the fuel mix screw on the bottom.I hope some of this makes sense and helps someone, go to youtubefor a whole bunch of pit bike or just plain 4 stroke fuel mix , and air adjust or air mix,try combinations of those terms in search and those videos can further guide youin the process.Once you've done this you'll never be apprehensive about replacing a simple carblike this one.Best to all/

I installed this on a Apollo 125 , And what a difference! Out the box the bike runs absolutely perfect!

Love this ! Makes my bike sound like a beast !

 First of all this is a genuine Mikuni carb! It actually has the proper stamps and made in Japan!! The only problem I had was they didn't include the 2 nuts and bolts to connect the arm to the carb. I had to reuse my stock ones and they weren't quite long enough. Except for that I have to say THIS CARB IS AWESOME!! I have an Apollo 007 125cc and the stock carb boged bad and would cut out without hitting the top RPM bands with a top speed about 52mph. Installed the new Mikuni and O M G! Huge gains in HP and torque, new top speed close to 65mph!! If you buy an Apollo or SSR 125cc you NEED this!

Installed on my apollo rfz 125 dirt bike. The stock carburetor wasn't the best so I bought this carburetor and man it woke up this dirt bike alot. Dirt bike runs good and fast.

Fit perfect on my SSR razkul. Parts were good quality and worked well. The only thing I needed to do was set the idol screw and was out riding.

Better then stock carb no complaints

This is a pretty good upgrade for the money. It made the bike start easier and increased the top end speed by 7 mph. The bolts it comes with were not long enough and very cheap. I used some extras I had lying around.

Installed on 125cc pitbike and it gave it a little more oomph. I've still got to get the right jets but it runs fine as is. The a/f mixture screw is on the bottom and you need to remove the carb to set it.

Installed this carb on an apollo RFZ 125cc, Bought bike brand new and it ran terrible. This carb brought the bike to life!! Runs great, maintains good idle, no adjustments made!!!

I installed this on a apollo x15, run completely different without even tuning it! The black spacer was broken but there sending me a replacement. Great people to deal with

Great quality for the money

I spent over $100 on a nicer carburetor but it didn't even work. I bought this hooked it up and it started the first time.

Poor quality contents, the carb is cheap and not authentic Mikuni, the internals are cheap. The air filter fell apart into pieces. The glue used on air filter broke down when gas made contact with it and it got into the carb and gummed it up. No improvement over stock, in fact I can not for the life of me get the carb dialed in on my RFZ 125.

Put this on my ssr 125 after the previous owner messed up the carb beyond repair trying to tune it. This made my pit bike run great, I can’t tell if it’s an upgrade from stock since it ran like garbage before but it definitely has a lot of power now

I put this on my 125 cc Lifan motor after changing my exhaust. It fixed the bogging out I had with the VM19 carb.

Very impressed and quick shipping

Really woke my rfz 125 pit bike up
