So the damn rain FINALLY stopped (3 days straight, I am not kidding) so I got to take the bike out for a proper first ride...

EDITED:

So, as it sits on my first impressions, and bear in mind I am still working out the changes to my fueling, definite boost in power, and a slight shift in the power curve, but only just a slight one. I think that just comes down to the nature of the CG250. Even with wonky fueling this thing felt way stronger than it did before the cam. Engine Revs up so much faster, and acceleration just feels much more effortless.

My fueling is all wonky though, as I mentioned before. At first I thought I had lean issues, but after some tinkering I believe I have it figured out now.

As I started the carb has a 35 pilot, 140 main. Idle mixture about 1 3/4=1 7/8, needle in the 3rd slot.

I thought I was having some lean issues at the transition from the pilot to needle, and also rolling out of the throttle from the main. Turns out i had that backwards. Needle was actually just a tiny bit rich in the third slot. I discovered that after moving it to the 4th and started having actual bog issues instead of just slight hiccups.

Other issue at the same time was getting fast idles like my idle mixture was leanm when I went to tweak it it would then drop and almost stall if I tried to adjust the mixture or idle speed more than a little bit. That issue went away and my idle went dead stable with the needle moved up. Basically the rich needle setting was allowing enough fuel to mask my lean idle.

It started raining again, so I can't test my changes. I have the needle set in the second slot and I went back to the 38 pilot jet.

As far as I can tell, the 140 main is pretty close, if not entirely perfect. I do believe it is still a bit lean up top, but I am going to wait until I can determine the effects of the larger pilot and leaner needle. I do have a feeling that I may need to go up to a 145, but we shall see when I get there.
