Just spent my first morning of wrenching on my new bike. Did the white spacer mod and tweaked the brass plug low idle settings. What a nice difference it makes to not be backfiring constantly!  

What a wonderful bike that you can actually work on without a computer! Shade tree mechanics still exist!

Thanks to all for their help.

I'm not much of a wrencher either, but I sure have learned to start replacing those cheap soft bolts and screws with good ones.
