I got the pipes on without any major issues, other than trying to wrangle the 65LB stock muffler out from beneath the bike. Surprisingly, these slip-ons aren't much louder than stock. A bit throatier but still quite.
I also replaced the speedometer. The odometer wasn't working. From the maintenance records in the owners manual and the mileage on the title, it looks like there's about 3 years worth of miles missing. It stopped at 34K, that was in 2009. The guy I got it off bought shortly after that. But, he didn't ride it much. The replacement speedometer has 41K on it.
I noticed that it's missing a bit below 4,000 RPM and cylinder #1 doesn't get as hot as the others (water spray test). The vacuum cap is broken on the #1 carb, betting that's got something to do with. I'll fix that and give it some new plugs and points and see if it improves. Running Sea Foam through it too, that really helped my 750 to run better a low RPMs. Everything else is working though. I spent about three hours trying to figure out why my running lights and dash lights quit working shortly after I added the turn signals back on. It kept blowing the fuse. I took the signals apart, removed the Vetter wiring harness and cleaned up all the wiring in the headlight bucket and they started working again. Must have been a dead short in there somewhere.
