I recently ordered a set of larger (32mm) vents from CB performance to swap out for the 28mm vents that come with the Empi 40 HPMX carbs. I went to install them tonight and noticed there is some serious slop as the CB vents have a smaller outer diameter than the OE (empi) vents.

Here is the OE Empi:


Here is the CB:


Empi on bottom, CB on top:




Is this normal? I emailed CB but have a feeling they are going to tell me there's not much they can do. Any thoughts?

I'd send em back.

I order my Weber stuff from http://www.piercemanifolds.com.

CB seems to be hit-or-miss much more these days. I haven't ordered anything from them the last time they screwed it up. Like Mark, I prefer Pierce, or my buddy over in Italy.

Wow those are rubbish fit ,CB went very Chinese some time ago and there stuff made many feel like they were ,sad really they used to be the go to place for GOOD stuff.
Our ''friend" in Italy provides great parts that fit and work for great prices and quick shipping...why go any where else.
