CDHPOWER Air Intake/Manifold Intake/Air Manifold Intake 32mm/40mm - 2 Stroke Gas Bicycle Motor Engine Kit Motorized Bike

Installed on my yd100 fits decent no leaks.I almost lost the oring opening package as it is laying separate not on the intake itself..wonder if others who posted 'no oring' didn't notice it when opening their packagesUpdate: developed air leak a week later due to o-ring deteriorating prematurely

It's a good quality piece and very nicely machined piece. Yet it doesn't come with the o-ring. The major issue though is that if you have 40mm spacing, you have very little "meat" on it to squish your gasket and seal well. It should work, but there isn't much gasket between the intake and the screw hole spacing. For 32mm spaced studs this is perfect , if you have a 40mm stud spacing you're much better off getting the bike berry version specifically for that spacing as you are going to be much, much more likely to develop air leaks with this one and with no real benefit.

AS WHITH cDPower always a great product

This is a very well made intake manifold. Clean edges and holes and went on with no problem. Plus, it fits for both 32mm & 40mm bolt spacing. But, like others on here, my black rubber o-ring was also missing making me fend for myself. I won't knock it down a star because it is an outstanding piece but the seller should just change the listing to not include the rubber seal. I'd still buy it again.

O-ring was missing, seems like a recurring issue with this item, I happened to have an o-ring that fit, other than that it works fine, great if you need just a tad more room for the carb, rather than going with an offset intake.

VERRY well made, however dose not come with the o ring, and its hard to fit it on a motor with an NT Carb because of the clutch cable routing. Im still looking for a good carb for it.

Missing oring. It doesn’t seal and you have to go out and buy more crap that you already paid for. Such a simple problem you think they’d have fixed now. Otherwise it’s a great product.

It didn't come with the plastic seal . Other than that product want damaged. Had decent packing

Works great
