Got the Newport running again

Last weekend I put the cylinder back on the bike and fired it up. It started on the first kick, which was nice. I've ridden it around a few times since then and it seems to be doing well. I've been checking the head temperatures with a temp gun, since I had to give up on my trail tech temp gauge. I haven't taken it above half throttle yet, but the highest temperature I have seen is 260 degrees...and that's even with 90 degree ambient tempteratures. I'm looking forward to putting some more miles on it.

metrakit machining

After soft seizing my metrakit 65 at the lafayeti rally a few times, I decided to buy a larger piston and have the cylinder machined. This probably saved me $60 compared to buying a new kit, but it took a while to find a machine shop that was willing to do it. I picked it up last night and it looks pretty good. It doesn't have quite as much cross hatching as I would like, but it isn't bad. I'm going to run it and see how it does.

Piston size: 43.85mm
Bore size: 43.92mm

That's about .003" clearance, which is what I asked them to do.

I also upjetted a few sizes from 86 to 91...just in case. I was hoping I had an 88 jet but I don't. Maybe one of the other Radium City guys will come through for me.
