no spark on 1982 gs650g

[Guest]

Hi I got a 1982 gs650g that I am building as a streetfighter. After working in the wires that are hidden in the headlight to change the speedometer, the bike doesn't spark on any plug anymore.

Anybody knows what could be the problem? The killswitch connections seem to be alright...

Can we find the wiring diagrams for my bike on the net?

After working on the harness, I noticed that a LOT of connections have been reapaired really bad, not even welded, just holding with electrical tape. Also, as I have retired the old speedometer and rpm, there are a lot of wires that I would like to take off so I'm asking myself if building a brand new harness including only what I need would be possible... Of course I would need the wiring diagrams to do it...

Thanks

Welcome to the club. I'm biased, but I like my 650G. As for the wires you may have dislodged, one wiring diagram can be found here. It is B&W but not too hard to read.

oops, that is the service manual, here is the COLOUR wiring diagram:

Once you study wiring diagram, you'll find your missing connection. butchered wiring is a pain.
To BigD_83- how's your gas mileage these days?

Thanks for the diagrams I finally found the problem, now the carburators will need to be adjusted

Sorry for the intrusion into the thread, but I promise to keep it brief.

The Dyna Greens seem to be really helping. I haven't done any long distance riding of late, but I'm still getting 40-45mpg. The last fill up was 40.25. There is some improvement to be had as I can still smell a little bit of gas at stoplights, but for now, I'm happy.

We now return to our regularly scheduled programming

Do you push it ? I tend to hang out in fifth right down to 2k rpm? my bike seems to not care
