[1978 yz80]

i was bored and decided to check out this forum again. same as always, no interest from anyone on old small vintage bikes. well, i got the girl running, but didn't have 1st or 2nd gear. took the motor back apart and split the cases. gears stripped. found a good set on ebay for 25 bucks, so i replaced all of em(mixed and matched to get the best) and replaced all of the case seal (which fixed my idle problem from another post). took it out for a little spin and i am so glad i decided to keep it and fix it up. first off, my son and i have something to talk about besided cleaning his room or not pissing his mom off somehow. we got to spend some great quality time together and i hope he was able to learn something besides the cuss words when i couldn't get the thing to idle. only bad thing is- he broke his collar bone playing football and can't ride it for a few weeks. we now have another project- a vintage ktm 125 to restore. we rebuilt his quad and i just re did my beater quad. now i want to restore the dt100. it does run great, but looks like crap.

Hi, You have my interest here. I am restoring a YZ80D and have it all together thanks to donor parts from a 78 yz80E. Trouble is I have no spark and am wondering what to do as this part of a bike is not my forte'. I can telly that it has a magneto and that there is no spark. The key was broken off of the shaft that the magneto is held on with and I made a new one. Beyond that' I'm stuck. Any thoughts? Places I could find a how to on the magneto ignition system. I've beat up google pretty bad and have found nothing....
