PZ30 vs Mikuni Carb Comparison with Pictures

TheGageinator · 01-19-2015, 06:32 PM

Here is a Comparison of the Mikuni 30mm clone and a KeiHin P30 30mm carburetor.

ID measurements

The PZ30 measures 30.48mm inlet and 38.1 outlet

Mikuni measures 30.353mm inlet and 39.37 outlet

Now some side by side shots. Mikuni on left, PZ30 on right.

The mikuni has 4 bowl screws the PZ30 has 3

The idle screws are different

This Mikuni came with a lever choke, the pz30 was cable choke. They are interchangeable between brands.

The Mikuni came with a nice coating of clear oil inside to keep everything in good shape. All edges smooth

The PZ30 had a lot of rough castings spots and extra metal hanging off in places. I also found metal shavings in numerous places. I have already corrected all these problems before the pictures. Sorry.

Yours came with a 30 slow jet? I've only ever seen them come with a 20.

Thanks for the excellent pics and comparison. The only comment I would add is thatI think the Keihin has a metal slider, and the Mikuni has a plastic slider.

This is very good information.

Thanks for taking the time to compare the differences, and post the excellent photographs.

Thanks guys! Sorry the pilot #30 jet was a typo. Glad you caught that! Fixed!

I had to buy #30 slow jets, so I was surprised to hear that yours came with them. Too bad it didn't.

sorry if I go off topic but..............has anyone tried to mount a aftermarket carburetor on a Skyteam V-Raptor 250 ?

and if so.............was it worth it ?

Not that I'm aware of. I think the V-Raptor uses a pumper carb for easy starting, so if it works, I'd leave it alone.
