So..... I was stupid and pinched the throttle cable putting the tank on. When I started the bike and it redlined. (scared the **** out of me and obviously p****d off the neighbors) It was at night and I thought I was pushing the kill switch, but I was actually pushing the flange on the light switch. I heard a screech, bike died. When I tried to start it, it was obvious I had no compression (removing the head confirmed I melted a ring into the piston). Parts on the way. But, before I tore it apart I noticed a distinct ticking sound coming from what sounded like the headlight area when kicking to confirm the compression with a gage. Sounds somewhat like when a spark arches. The bike is new to me (hence trying to find the kill switch in the wrong place) and I had just put the headlight and computer back on the bike (that was in a box with tons of other parts). Reading through all the posts here, I'm hoping I didn't fry the CDI, but it really sounded like the clicking was at the headlight or the little computer gage.
Any ideas? As soon as the piston set comes in I can do some more testing, but really anxious to get the bike running (first Trials bike!) and may need to locate additional parts.
Thanks in advance.
