NIBBI Racing Parts Replacement High Performance GY6 Intake Manifold Intake Manifold Boot for GY6 Engine Scooter 125CC 150CC

Worked flawless on a 139qmb 50cc short case engine. I put a big bore kit on to 72cc but kept stock head. At first I rigged a 5 hp Briggs carb onto the engine using this intake and it didn’t start easy(no choke on the carb I used) but once it did, it ran way better then Expected. I made the up grade to a nibbi carb I believe the 24mm one and after swapping around the included jets iv gone from 23.4 mph to 34.3 average( remember from Briggs carb). I highly recommend going with the full nibbi line up of throttles, cable, carb, and intake. I found a k&n air filter for $24 that fit perfect on here also. It’s impressed everyone who’s rode it and iv put well over 1000 miles on with the bore kit and nibbi intake system. The only thing that changed was the the location of the nipple that the vacuum from the head attaches switched sides and I had to remove the little plastic cover over the timing chain tensioner is all. But it shorten and cleaned up the look on my bike. Great solid products from nibbi and also I received some packages in less then 24 hours with prime. But they did get shipped from only one state over. All packages were received in less then 48 hours from them

キャブレターの水平角度が取れて助かりました。商品の造りも、大変良く出来ていました。

So i had to send this back it didnt quite fit my bike but I highly recommend it! The part was excellent much nicer then what Iam using, it was shipped very fast and even the return process was fast and painless . 10 star seller in every way

Looks well made and good quality material and machine work besides a little bur I scrapped out my fingernail

Product worked as advertised had it come with bolts and a vacuum cap. A trip to autozone and lowes made it work. I installed this on an Apollo DB-x18.
