Hopefully they have some beaters to ride instead of that beauty.

Yeah I'll be taking advantage of the supplied benders for an additional fee.

It cost $200 where I live, good thing is if you pass the written and the driving test they give you an endorsement and you go to Dept Motor Vehicles and get it added to your license. There were 12 in my course and 11 of 12 dropped the bike at least once!

Well done mate. Keep up the good work.

I’ve got a shed full of CG , CRF And horizontal Honda copies waiting for new homes. Love what you are doing with yours

Ps. I love JenniesGarage. Those two make me laugh. Great inspiration

Received the Keihin PZ30 with throttle and filter kit in the mail the other day. Pretty happy with it.

But thought it would interesting to make some comparisons to the Mikuni missing the slide that came with the CG250 and the Keihin 27 that came with the Honda 163.

The most notable issue to me was how much of a restrictive dog leg with the inlet adapter the Mikuni came with.

Also with a touch rotary porting managed to open up the inlet adapter that came with the Honda 163.

no real issues with interchangeability the Honda inlet adapter mates up to the CG250 head perfectly and the O'ring seal to the PZ30 is adequate.

Appears that the Honda inlet adapter also has in built heat insulator too. compared to the other adapter's separate plastic spacer.

I have not opened the PZ30 to see what jets it came with.

Still waiting for more parts, can't do much with the build until my new piston and rings turn up.

That looks to be a PZ30b or pumper carb in contrast to the the PZ30. A good carburetor with performance in mind. Wonder if you can get that PZ27 up and running? Would be nice to compare them, alas the Mikuni is not salvageable it appears. Something about getting an old carburetor running again.

I got the PZ27 cleaned and running on the Honda 163 engine. but the throttle grip was past its prime.

Then looking around and the PZ30b pumper seems to turn up in mentions on the regular. and the complete kit on Ali was reasonably priced and came with the choke cable bracket that was missing on my P27 I have mildly ported the head so I doubt the PZ27 would keep up and keep to lean.

Basically the PZ30b kit was a triple win. but the real real deal will come when the bike finally fires up.
