Sadly, something I learned while trying to source parts for my little Honda SL-100 project a couple years back...is that Honda shops are more interested in selling new bikes and accessories . Gone are the days when your local Honda shop was the place to go for parts when restoring an old bike. So far I've found most of what I need on E-Bay. There are a couple of good motorcycle wrecking yards in town....that have some older bike stuff. In the summer time there is a big Japanese bike show and swap up in the foothill town of Auburn, California, that can yield good results at times. Last summer the attendance of vendors was down from previous years...but I did find some good stuff.
And I have my stash..my rathole of parts acquired over the years..
A low mileage crankshaft from Florida...as was the cam chain. The rings came from Japan.
Just got in from a trip to Monterey area...to find more E-Bay items had arrived. This time an NOS top tensioner sprocket, good used front and rear tensioner assemblies, and a genuine Honda cam chain "smash link".
The NOS sprocket from Arizona, the other sprocket and roller assemblies from Florida, believe they are from the same motor that the crankshaft came from. The NOS sprocket from San Francisco. Waiting for some parts from Canada as well.
Need to find a good used or new.. bottom Cam chain roller now. I'm ending up with two different sets of standard rings. One is an NOS factory set with the original one piece oil ring design. the second set are new replacements that come with a three piece oil ring. Will have to think about which type to run. I do have another 450 twin, a four speed "'Black Bomber". That bike is a runner, but is stuck in gear...possibly just a shift mechanism part that has loosened up and jammed...but that's a whole 'nother project.
