Udp 4port still on market? Cant find 1

They are still on the wholesale price list. You will just have to find someone willing to add one to their next order and ship it to you perhaps.

i think we have some Udp coming in the states soon.

Champions are coming to the North American market first. The UDP engines will follow shortly.

I had a look in the workshop at my spares, and I can build you up a new UDP 4 Port (complete except for head shims).
I have other UDP spares left over, so can offer you the following for NZ$200 plus postage:

New UDP 4 port engine as above, plus

New spare UDP crank
3 x new spare UDP con rods (slightly different to the 21-0600 I believe)
1 x new spare cooling head

Let me know if you want to proceed and I will build it up for you.
Email me at [email protected] as opposed to a PM (I don't log in on here all that regularly these days).

Interested, meaning engine complete with bearing except head shim? Pm me. Thanks

The champion u mentioned is it using 21-2205X (gx2) or 21-2205 (gx) p/s? Or new p/s set?

The piston and sleeve is 21-2105.

The piston, sleeve, piston pin, G-clips, and conrod is 21-2205.

with lower cg and a little weight reduction, guess it will perform better

Looking at a gx7r with 5 gallons on it..hes asking $75. Deal or no?
...

It is hard to tell, seems a little high. Probably worth it if the crank is not worn and the rod has been replaced.

Funshobby have em in stock

He didnt mention it. Whats it worth with 5 gallons on it assuming it was broken in proper and the rod has not been changed?

Don't worry about that one, Grizz just posted on Facebook earlier about the new GO Engine, GX5R piston, 5+2 sleeve & rod in the UDP crank case, not released just yet but not to far away I think, sounds like a good engine.

Part of what was on the WERKS NZ FB page,

"Enter the GO Champion 5 Port .21 race engine from GO Engine Co.
GO have re-introduced the GX5R 5+2 port sleeve and crank into an upgraded crankcase and cooling head design in the Champion."

I ordered the udp from grizz d. Anyway fyi:

-The udp crackcase/crankshaft can fit 21-2205 p/s/c set for sure as i tested it
-the udp rod 21-0600A i think is same rod as 21-0600, not yet do measurement but identical
-imo go engine will get better runtime by using nova carb (dont get offend)
