Bill,

Sorry we did not bump into each other in Hiawassee.  I’ve got maintenance planned on the R65 for this weekend.  I’m undecided about the Huntsville Great Chicken Rally in two weekends’ time.  Let me know if you’ll be around

"Not sure if the 'victim' ever solved it."

I know I was victimized by a clogged fuel cap. My '81 R65 would stall at idle and/or run out of breath at cruise over 60 mph.

Replacing the fuel cap eliminated the stalling. Ultimately, overhauling the Bings turned the bike into the pocket rocket it is now.

Just an update on findings so far.  Nothing conclusive as yet, but here’s what I’ve done/the plan.

I did a quick check of the diaphragms with the carbs on the bike.  They’re OK.  While I was at it, I decided to do a quick cleaning/maintenance job on the carbs (carbs off bike – external clean in “dirty parts” parts cleaner - dried off – float bowl and “choke” mechanism removed – internal clean in “clean parts” parts cleaner – dried off – a few cycles of squirting passages/parts with Berryman B-12 and blowing through – reassemble including new silicone gaskets on floats bowls – took about two hours).  Nothing was really dirty, outside or internally, but I may have done some good.

As I’m fiddling (I knew this would end up in fiddling) with the fuel system, I am going to clean out the gas tank, replace the fuel lines and, as I have the tank off (more fiddling), fit a Dyna coil as a preventive maintenance measure.   I have all the bits for the fuel lines to hand.  I ordered the coil from Motorrad Elektrik yesterday, so it should arrive tomorrow, and I’ll spend tomorrow evening putting things back together.

I’ll be ready for the weekend.  However, weather is looking terrible for the Chicken Rally, so I’ll probably opt for a local fun run as a “shake down” rather than aim for the 360 miles or so round trip to Huntsville.  I’ll let you’all know if I have banished the hesitation, or not!

Thanks.

Mark
