I recently purchased a 1971 Honda SL125 with a few issues.
The first issue was that it would not run worth a darn for more than 45 seconds. I determined that the spark plug cable was not attached to the spark plug well enough. After looking at the spark plug, I decided to install a new one. After that, I have been able to start it easily enough. I resolved the first issue on my own.:smile:
Now for the issue that I am unable to resolve: While parked, the motor will idle now that I have adjusted the carburetor. I can also rev up the RPMs at or above redline just fine. However, when I took it for a test drive I could not get it to go faster than 30-32 mph. When I increased the speed, the motor would sputter and start to cut out above 6000 or so RPMs in gears 3 through 5. I tried adjusting the high-end jet screw to no avail, however, while parked, I could see and hear the difference in adjustments of this jet, but no matter how I set it, 32 mph was top speed without causing the motor to sputter and cut out. Any suggestions would be greatly appreciated. Thank you in advance!
There are other issues, but I feel I can resolve them on my own, such as replacing the light bulb in the headlight and changing the motor oil. I will even add turn signals after the motor will run properly.:wink2:
