sooo 38 or 40?

I searched the jetting threads already and didn't find my answer so here goes.... this is my first time with these style carbs on the CB360. I need to go up on my slow speed jet, I'm wondering how much change you get if you go up from 35 to 38? With the 2 into 1 pipe I've got a pretty good...

yes sir same side.

the rings were OK, they had some crud on them that looked like major damage with the closeup focus of the camera. the main culprit that took a couple years off my life was that cracked piston. It was so bad that oil would come out of the exhaust pipe header joint, and out the back of the pipe...

and no more smoking......

lesson learned. The aftermarket cylinder base O-rings are too large and wouldnt let the cylinders set down on the case. This left a gap where the oil could leak through. fixed

second question- has anyone had the cylinder base o-rings keep you from being able to fully seat the cylinder down on the case? this seems to be what's happening

interesting find on this engine- while waiting on my fresh bore job on my new cylinders I found that this piston was cracked. The cause of the excessive oil smoking. Now that the engine has 2 new pistons and bore, no smoking.

are there any metal oil transfer tubes on the BACK side of the cylinder block where it drops down onto the crank case upper half? I know this is where the oil gets pumped up to the top end, and I know there is a tube with a rubber seal on it between the top of the cylinder block and the head...

I dont think there's any mystery here. Looking at the oil ring there are some spots where it shows no contact with the cylinder wall. Even though it measures concentric, it's obviously not perfectly round down inside and it needs a fresh bore.

I looked at the rings, they are fine. new 68mm pistons coming. I tried to save some money initially by just doing rings. This time it bit me in the butt. oh well, I'm still ahead on this bike it only cost 100 bucks and I've done everything else pretty cheap. I lace my own wheels. Those black...

I build my own wheels

something not so obvious is wrong. and its gonna be simple too....
