You have PM

There are some posts in this thread about what the Champion is all about. Go back a few pages to find them.

Shane at Werks New Zealand is breaking one in. He may be done by now. You can get hold of him or wait for him to check in here.

ok great..

Is the old 7port gx7r p/s/c still exist? 21-2207

Nope it´s gone, all options are 2205 variants now. Champion is a great engine I have over 3 gallons on it. Only issue I found is the carb needles moving due to the orings being loose.

Try Novarossi carb 24069, very reliable

Threadlock did the trick

nice one noted..

Any comment with the 2103 pipe compare to 2072? My opinion:
-2103 good bottom but top end not strong as 2072
-2072 strong bottom n overall pipi even rev higher

anyone have NEW p/s/c 21-2207 (7port gx series) to let go at reasonable price?

Someone have hear about this GO engine R21-G5PT ?
I found few photos on a Taiwanese shop's Facebook page.
The price seem great !

Is a good engine, let just say gx5r, go champion 5port to sum it up.

Looks like DLC-coating on the crankshaft. If so, then this is a serious option.
