Back in December one of my neighbors moved, and was going to put this beat-up Chinesium dirt bike on the curb. Another neighbor grabbed it and saved it for me. I’m pretty sure it’s an SSR. It definitely has a Lifan 125cc engine, which is a Honda copy made in Thailand. I didn’t do anything with it over the winter though, because my garage is unheated and I didn’t feel like being cold.
I figured this would be a good quarantine project though, so I finally started working on it a couple weeks ago. First I drained the putrid gas, checked the oil, and checked for compression. Both were good.
As I dug around it. I realized the throttle was stuck shut. I pulled the carb off, but could not get the slide out of it to release it from the throttle cable.
So I dunked it in Pine Sol and left it behind for over a week. I also ordered a new carb for the whopping sum of $13.58. As gunked up as the old one was, I’m not messing with it. Surprisingly when the new one showed up, it’s a genuine Keihin and not a Chinese copy. Color me pleased.
While I waited, I decided to check the spark. I pulled the plug and grounded it to the head. Upon kicking it over, spark was present.
The carb showed up a few days ago. When I pulled the old carb out of the Pine Sol, still the slide would not release from the carb. This time I resorted to brute force. A big screwdriver and a set of needlenoses busted it free from its cell.
I then put this goopy mess into the Sol for a couple hours, so I could get the throttle cable out easily.
That end achieved, I swapped the new carb on, which came complete with a new fuel filter, fed it with a new fuel line, gassed it up, and kicked it over!
I kicked again and again and again...
I then realized I left the shipping cover on the carb’s air intake ... D’oh!
That removed, it fired right up. It idled nicely, it revved nicely. Success!
Next up for this pile: piece the beat up body back together (the seat mounts to the body, so it’s a must have), change the oil, and order a front brake lever, as that part is M.I.A.
Will I be proper dirt biking? Of course not! But it’ll make a fun pit bike to tool around the race track ... whenever we can do such things again.
