Yup, fresh oil and filter and all seems well. Starts right up, idles smoothly, good throttle response. The RH pipes are still smoking a little, hopefully just burning off the final residue.dontwantapickle wrote: ↑Mon Mar 10, 2025 12:28 pmJust call it an engine flush and move on.toomanybikes wrote: ↑Mon Mar 10, 2025 6:02 am I did start the engine 2-3 times to try and blow the residue out of the pipes. Probably not a good thing now that I realize the gas had seeped into the oil, but they were only ~5 minute sessions at 1-2k rpm so hopefully no damage was done.
On mine, the petcock failed, Oil on the gas. I just replaced it, no engine damage done.
(I think Pingle makes a non vaccuum petcock).
Another thing that happened with my Valk was just flooding.
Turns out that the floats are non adjustable and the pressure to shut off the fuel getting into the bowls is controlled
by those little spring pins in the float needles.
After just over 100,000 miles. the little springs were worn out and I had to replace all 6 float needles.
Probably not your issue at this time but something to keep in mind.
If yo do pull the carbs, get rid of that smog stuff. you don't need it, those vaccuum lines will crack and start sucking in air.
I'm just using a small aux tank, so the pressure is low (very little height diff) on the valves and the petcock is not involved in the process. I may switch to a pingle just to be sure. I hate the vacuum drive systems. Mine still says ON, OFF, RES, but also has a vacuum port on teh back, so I assume it is vacuum controlled.
Ideally I'd go for a ride to burn off the last residue, but the rear tire is hilariously worn.
