The exhaust valve clearances have been closing up at each valve adjustment. I actually did a couple valve adjustments whilst on a 2000+ mile road trip, including one at 3:00 in the morning in Ely Nevada:
I'd have done it the afternoon before, but it was 100+ deg F out there. 62ish degrees under the full moon.
Yes, I'm using TP for shop towels. So going over my logbook, the valve clearances had been stable until the past year. They've closed up at least .020" since then. That's enough recession, quickly enough, that it's time to get the heads rebuilt. I need to have this bike ready for pillion auditions this fall. My local guy gave me a quote for $$$ and time, and he'll get the heads tomorrow, when he opens for business. Today's task was to get the heads off. Here's the right one:
And the left one:
I don't know if it comes across in two dimensions, but both exhausts are flush with the surface of the seat. I don't know if it's the margin used up on the valve or the seat receding, but it's time to replace both.
Reassembly posts to come in a few weeks.
Call me Mel. Some years ago- never mind how long precisely- having little or no money in my purse, and nothing particular to interest me at home, I thought I would ride about a little and see the other parts of the world.
