My 2015 GG 250 now has 920 miles on it.
I decided to do a refresh on the top end. I've never had it apart.
Ran a compression test, came out to 140psi.
The power valves were really clean, a testament to how clean the SmartCarb operates. The left side power valve chamber was dry also. No spooge build up.
I ran Amzoil 50:1 for a while and have now switched to LUCAS oil.
Flapper had little carbon build up.
