Hey guys,
I have a 2005 Roketa 125cc pit bike that I recently purchased in terrible shape for 100 bucks (you know the story if you've seen my SSR budget bike thread). It needs a ton of work, not the least of which is a clutch diagnosis/replacement. However, since I've yet to hear the bike run, I'd rather not spend the money on a clutch, in case it needs other, more important stuff first. The bike came with a stripped kick start lever and kick start shaft with pretty severely rounded teeth. However, I was able to get a new kick start lever to grab on the shaft, and with the help of a hammer I tapped it on fully and tightened the bolt as much as possible. So, earlier this afternoon, I gave the carb a good, thorough cleaning, tidied the bike up a bit, got some gas in it, and gave the kick starter a try. It kicked over fine so far, and seems to have good compression, however it would not start. Tried to spray some starter fluid in the carb, and still nothing. I pulled the plug to check for spark, and it has none. So, at this point, I have a few questions:
- This bike has the on/off toggle style kill switch (picture below). It is in bad shape. If I want to delete this switch, do I simply unplug it? Or do I have to connect its two wires together? Neither of these gave it spark, but I want to make sure for later.
- Where and How should I check voltages to figure out what has failed? I have a basic knowledge of how ignition is achieved on these bikes, but I have zero knowledge of how to diagnose it. Should I be checking signal from the stator? Or should I be checking voltages in/out of the CDI? The coil?
Here are a few (crappy) pictures of the system on this bike.
In the first picture, you can see the style of coil on the bike, as well as a lot of the melted insulation in areas that the PO allowed the wiring to get too close to the exhaust (including the top corner of the CDI).
In the second, you can see the wiring that comes from the stator, wraps over the top of the frame, and ends at that connector. In the middle of the picture you can see a section of one of the wires is missing insulation, and the wire there is an ash gray color, not copper. That could be my problem right there =P.
The third picture is just for reference, in case there is something there that I can check or test.
So, are there wiring diagrams or something that can help me out here? I have no idea which wires do what, but if I know what to check and what I'm checking it for, I have the capability to put two and two together =P. Any help on this would be much appreciated, I really wanna figure out the specific problem before I start buying parts (this is as much about learning as it is about a cheap budget bike). Thanks in advance =].
