UAUS Adjustable CNC 32 mm - 40 mm Air Intake Manifold With Connector for 49cc 60cc 66cc 80cc Motorized Bicycle Bike Gas Bicycle Motor Engine Kit High Performance Silver

Way better than the cheap original kit item for motorized bike engines.

If you are building a powered bicycle and you are experiencing carberator fitting problems then this is for you. The carb on my engine hit the center bar. I purchased the curved extension for the carb. It really stuck it out too far on the one side and o had to do a lot of modifications to get the clutch bar not to hit the carborater. I ran across this piece and all my troubles were gone. Easy install. Part arrived on time and was exactly what I needed to fit that motor in the bike I wanted it in. No performance loss at all. If anything it tan better too as it's a machined and polished part. The through hole is very smooth for a better air/ fuel flow threw the neck. Great value for the money.

It's a good manifold. Too bad the carburetor is so stupid.

No matter how much you tighten up on the bolts it leaks even with gasket maker and the bolts bottom out and washers will not fit in the slots... it is the slots that cause the leaks and it pulls bits of gasket maker into the inlet of the motor.. save time and money in the long term and buy the correct size intake and gasket

Product quality is superb, didn’t have a issue at all with mine, all intakes should have a oring built It, that was very helpful. All in all this is nice to have on a tight frame. If you don’t use the Bottle Booster attachment just find yah a bolt or something to plug the hole, just

It fit fine, but, it's short and stubby and comes out straight, so, the carburetor is now rubbing the clutch cable. I cut a piece of brake cable jacket and put over it, seems okay, but could be improved on

High quality👌

great buy!
