I'm new to this site, so please be gentle.
I've just completed refurbishing a TL125 K1 imported from the US. I've rebuilt the motor with many new parts, and am happy with it mechanically. I have only a very faint occasional spark though, and the bike won't start.
There is only one generator winding which I have checked for continuity. Its resistance is about 3.5 ohms.
The HT coil is a new pattern one. The points and condenser are new, gapped and timed correctly. I've replaced the wiring, such as it is. Now I've run out of ideas. Do flywheels loose their magnetism with time? The flywheel is lined up with the key on the crank, so I'm assuming the mangets are phased correcly with the generator coil. I can't find a definitive figure for coil resistance, but 3R5 sound reasonable. It's sparking but only just visible if you look closely.
What does the panel think?
