nibbiCarburetor PWK28mm,fit 200cc—250cc Motorcycle Engine with Carb Jets for DirtBike MiniBike Pit Bike GY6 ATV

Shopped around for a while for a replacement for the aftermarket carb fitted to my bike and am so glad I found this company. After running through a few of the included jets and varying needle heights my dr250 runs like a top. Very easy access for adjustments as well.

I don't normally leave reviews, but this will save some of you bunch effort,time and $$. I recently purchased a knock off pwk 38carb and it had blank Jets,plastic idle screw and a needle with no marks either. Spare Jets and needles were blank also. The cost was $40,so you get what you pay for. After several upgrades, real Jets,real idle screw, real needle, cleaned out mfg debris,..it ran ok but was hard to start and erratic idle once tuned!! Tracked down to a cracked cheaply made choke assembly,which they sent a replacement for fast. So it now idles and ran good now,especially for $40 +20 more for upgrades. It still was very lean in the midrange,even with a huge 180main,and the needle clip on the lowest notch!! I would pop and blow 2 ft flames out the tailpipe each time it decelerated..that wasn't normalI upgraded to the niici carb to just try it because it had the extra adjustable main jet(which my own 1997 cr250 carb had an electric solenoid version of stock) ..I can tell you theres a huge and immediate nite and day difference in the knock off pwk 38 and the nicci. Huge improvement with instant throttle response..idle mixture and speed set in 30 seconds ,,not 30min!!! Only top materials like red billet throttle slide cap and bowl drain ,,the slide was much tighter tolerance,,the idle was much lower and stable. Would buy again in an instant,,well worth the money. If you know how to tune dirt Bike carbs , had a beater of bike worth only $400,the $40 pwk knockoff will work fine.. but if your want a top quality carb that's easy to tune.,,the nicci is a bargain,,,at half the price of a 20yr old pwk38 selling for on fleabay

easy to install and had the bike running better than new

Quality product as it should be for the price.nock offs are half the cost.Good performance vs c.v carburetor .suzuki dr350 oem bike.tested elevations 2000-5500 FT.out the box to rich,moved c clip still rich change the main 132-130,c clip top the needle turned high jet off still black spark plug.main jet down to 128 main jet getting better slightly black plug with hi jet screw open 1 turn.main down to 122 even better h.p. up high top.change again 118 main &down on pilot/slow jet 32 down to 30.good clean plug.still little rich down low.good power with throttle response.Threads on fuel bowl bolt could be better,I do like the o ring gasket.

What a great carburetor for my Honda gx390 installed it and ran perfectly. Definitely worth the buy

Garbage

Don’t quite fit properly

I recommend this product. The difference compared to the stock carburetor is night and day, I was on second gear rolling about 10mph and when I opened the throttle all the way the bike jumped and the front wheel lifted of the ground(out of the box not tuned to the bike). The only downside is that it takes some time to install. You will also need to get a pivoting manifold flange (if installing on a 50-140cc engine) to make the angle less awkward.
