583 miles
It’s close enough to 600 miles, so time for the next “service”. All that’s really needed here is an oil change, but I’m doing a bit more as the bike hasn’t been running quite right: it sometimes pings under medium load and there is more vibration than there should be.
Adjust valves
Seems like I’ve yet to learn how to drain the oil without getting it all over the garage floor. One of my containers is too large to fit under the bike. The one I tried this time was too small. Back to the drawing board.
There were no metal bits stuck to the magnetic drain plug. At 1200 miles I’ll pull the oil pan and see what’s stuck to the magnets glued to the bottom of the pan. The oil was drained with the bike hot. Several hours later, when things were cooled I re-torqued the heads and adjusted the valves. They were close, but needed tweaking.
Loose bolts
The previous owner came by last week to see what I’d done with the bike. He pointed out a loose bolt on the center stand. So as part of the service I checked/torqued all nuts and bolts. The nuts holding the carbs were also loose again. I torqued them down (tighter, this time) but will monitor them closely. I’m sure this helped with my carb tune.
Hot pipes
That black smudge on the exhaust pipe is what happens when you get the cord to the timing light too close. Don’t do that. I caught it in time – the timing light still works. The points were checked and adjusted and the bike timed. Then it was time to take a ride to get it up to temperature for carb adjustments. Once at operating temp I set the idle speed, idle mixture, re-tweaked the idle speed, and made sure the carbs are balanced at RPM. The throttle cables had stretched, so the balance was off. They’re set quite nice, now.
I added a bit more air to the tires this go around. This is at the suggestions of some friend and is in the realm of “experimentation” at this point. So far I don’t notice any difference in handling.
Went for a ride. The bike is the best it’s ever been. No more pinging… no hesitation… it’s fun to ride. But with the weather turning summer like I’m having problems starting the bike when warm. When cold the bike starts 1st or 2nd kick. When sitting for only 15-20 minutes it can be a pain to start. Got to work on my warm-start technique, I guess.
