CL360 runs poorly when warm
I have a 1975 model CL360 that runs well when first started. After it warms up....10-12 miles...it loses all power and jerks like it is "vapor locking". It idles OK. I have changedout the coils only because I had some spare/used and it acts the same. Any suggestion where to look next ? :

Are you sure? If it were simply blow-by, I would expect it to run shitty the entire time.
If this happens regularly, it obviously has something to do with the motor heating up. Have the carb/carbs been tuned recently? A poor tune can have effects similar to this.

Re: CL360 runs poorly when warm (Quiks66)
Sounds like it.
My Integra had similar symptoms. Everything is ok when engine is cold and 'tight' but when warmed up, the expansion leads to loss of compression and/or blow-by. My 2 strokes in RC cars/helis exhibit similar symptoms.
However, the mixture is something I totally overlooked. A tune that is too lean will cause the symptoms you describe as well. Look into that first.

Hey, welcome. I'm a little new to motorcycles in general and Hondas specifically, though I just picked up a CL350 project not long ago.
