Great weekend for cruising here in Connecticut so we took the VS Speedster out Friday night. After about an hour, I noticed it running up near the "warning" level of the temp gauge. Heading for home, it started popping, bucking, then finally fuel starved and died.
My first thought was the Seafoam I put in the tank last time I filled it broke some crap loose and I had plugged carbs (dual Webers). I continuously sprayed carb cleaner in the carbs as my wife cranked her. After quite a while, it back fired a couple times and started to rev. Maybe just because it cooled off a bit? Any way...got it home safely. Took her back out yesterday with a full tank of fresh gas and the exact same thing happened. She's now back in her garage and I'm going to start diagnosing.
A couple things I'm thinking:
- Remove and clean the carbs (this situation has never happened before so I'm leaning toward this as the issue) - Have never done this so any suggestions would be great.
- Relocate the fuel lines and filter away from the heat of the heat tubes and fan shroud
- Adjust valves (maybe too tight?)
- Rejet the carbs to larger jets?
Yes, my engine seals are in place, and the compartment is pretty well sealed up. Oh, the car is a mid-late 90's VS with an 1835.
Thanks for your thoughts!
