I have been riding this bike for a while now with no problems and had it all dialed in "I thought".
Decided to take a good long hwy ride yesterday to. Bike ran as usual for about an hour. Then it started bogging down seriously
The 1st time it happened I was able to get it back to normal without stopping by twisting the throttle back and forth, at least that's what I did. 2nd to 10th time It died and I had to pull over. I noticed it happened AFTER coming down very steep hills under engine compression. The fix was a 10-15 min wait and then the bike would start and run fine, for about 15 mins of riding before it died again. 8 stops on the way home. On one stop, after a wait I stood the bike up off the side stand and fuel started free flowing out the bread box drain? That only happened the one time and petcock was in the free flow position that time.
I'm just heading out to the garage to pull the air filter box and check the gas vent routing, carb bowls and gas lines.
P.S. it did not matter which direction I had the petcock turned, it happened in all 3 positions. If just one bowl flooded, would this cause my issues?
Any thoughts? .... I think I answered my own question, but why just coming down hills with no throttle on?
