PWK Carburetor 21mm Racing Carb 50cc to 100cc 2T 4T Engine Carburetor Kits for Dirt Bike Motocross Motorcycle Scooter ATV Quad with Air Filter Intake Manifold Carb Jets

Great carb needed a little bit of tuning to run good but that’s expectedLooks good and easy to work withGood for the priceOn 1986 Suzuki sp-125

Pretty slick. I put this in a thumpstar tsr190, it ran way better than the stock carb and went faster with better acceleration times.

no problem. It works as it should

It’s a good product for being an off brand Chinese carb, yet there are some fake stuff they add to make it seem more high quality. But looks in pretty good shape. Also something that’s kind of annoying is that the air filter came with a dent in it. Not that big of a deal but definitely noticeable. For 40 bucks it’s a pretty good deal though.

Great carb but for anyone wondering, 26mm carb is a bit too big for Predator 212cc. The PWK is also great for higher RPM. If you're just running ungoverned 212 with stock internals, just go PE22 or PE24 with 36 pilot and 115 main for temps around 75 and elevation of 1000'.

I ordered the kit. It did not come with the promised air filter and fuel filter. Also, the jets were inaccurate. The last gripe was that the entire carburetor is light and thin compared to the original carburetor this one is replacing.That said, once you put genuine jets in it and get an air filter from AutoZone it's not a bad choice. Even with buying the jets and filter that I wasn't expecting, it is still way cheaper than a genuine Mikuni.

Works perfectly

You don't have to read the rest of this if you just want to know howto hook it up, I went 'seat of pants' on this and winged it to a degree,here's what I found that worked;It comes with two outlets linked by tube so nothing to do there, I justput 'drain' tubes on all tubes other than the largest 1 , I hooked fuel upto it.The angled, knurled screw on the left side, seems to be the idle (speed) screwjust leave it alone for starters, then next to it to the right is a horizontalscrew, this appears to be the air mix screw, screw it in all the way gently,don't crank hard on it, then back out about two full turns, revolutions.I write this as if you're a noob, as I am too. It will probably takea lot of kicks or elect starts to get it going if you're not lucky, I hookedup a battery assist to my e start bike, it needed it. I pulled the choke outat first then once it finally started and I let it run a bit, having to work thethrottle to keep it running, I put the choke back in. Bike stall several timesas I adjusted the air mix screw, and idle up enough to keep running.I should add, when you install the throttle cable into the internal slide,DO NOT PANIC, it is not like other carbs, the little white plastic piece insideholds it against the carb housing and keeps the lead end piece secured,I freaked out at first, seemed like there was no way to secure that lead end,there is , you'll see, just work with it and eventually you will see what I'mtalking about, your cable end is not too small lol, that's what I'd thoughtat first.-----Just got this today, and had to scour the internet to try andfind something close to this to get an idea how to set it up, andyes, I mean no, there is no carb exactly like this, I believe its a clonebut it is not exact match of anything that I can find.Comes in a gift quality container, looks awesome, seems to workwell, though my bike bogs at low idle, that is probably somethingI just need to fix with different low get, or something, shrugs...If this came with instructions it would be worth 10 stars, but thereare about 5 outlets/inlets that are anyone's guess as to function, Igot lucky and got it working lol. The choke system is fantastic,I wanted to eliminate the choke lever on my handle bar, this is partof why I bought this. I installed this on my Trailmaster TM31, it'scalled 250cc, but it is actually 223cc zongshen engine, modeledsupposedly after the honda crf 230cc which is also actually 223 cc's.I think this carb is also good for actual 250cc engines as well.I'll change my star rating if the company mans up and providesat least some level of instruction for it so others don't face the samefrustration that I had to, plus with instruction, perhaps, I could getit dialed in perfectly as well.
