Hi, chasing a few issues on my '72 R75/5 (I have also the annoying self-starting issue - ready to throw this bike away).
Here's a new one: I just did a huge ride around NE - no issues at all, now if I ride about 4 mins - all is fine, bike idles and runs well - its slows down like the gas is off (was not off) - then backfires (I believe on the right side) then dies...completely. I roll to a stop - two seconds later it will now start right up and idle fine and drive fine - if not a tiny bit off, or sluggish...hard to explain. I can ride it around for 20 mins and nothing, won't happen again.
This has happened twice now. Possibly related - I am seeing a lot of carbon on the intake tube to the right carb...
I checked for water in the bowls, and debris, but seems all okay. The plugs are perfect...
I was thinking to check valves, would a too tight valve (exhaust or intake) cause this behavior?
any thoughts?
thank you for your time
Chuck
