With warmer weather rolling into our area, I took several hours to make needed improvements to my motorbike.
Over the past few weeks I have:
Removed the engine and improved the motor mounts. That went about as well as possible.
Improved my homemade beer can air filter. I found a perfect thin piece of styrofoam filter material that works perfectly. I mixed my pieces, cutting them more precisely to maximize airflow.
I've spent hours trying to perfect my fuel line, using all types of fuel hose material.
So, today. it was strangely warm and I took a trip to the market. The bike jumped very quickly when I goosed the throttle and I had a great ride to the store until the engine died just as I stopped.
On the return, I could not get a good engine run. Oh, it wants to run but it just won't pop and go. I can pedal and it will purr but not enough giddyup to take the stress from my legs. I played with the choke a little and I got a pop out of the motor and shortened my pedalling distance, but not enough. I look down and - guess what? - a little fuel spewing out, thankfully away from the engine (which isn't very hot now anyway). I pedalled home the final quarter mile.
Very quickly I cut a new piece of leak free fuel line and took a test ride. No change; the engine will run but no energy. No gas kicking out of the exhaust. Choking seems to make it worse. I was very frustrating. I have spent a lot of hours on this thing in the past week! It is always something.
I have the feeling that the thing is running too rich...either too much fuel or not enough air. I checked my filter. the thing was running great just minutes earlier. It's very frustrating.
