83 850 GL: Ingnition cover / Grips

[ATX 850]

I just picked up my second GS after many years away. A good deal on the bike, Bad news is that it was laid down on it's right side and the ignition cover was destroyed and some of the internals are tweaked.

How do I replace the right side black rubber / copper coil contacts? Any specs / spacing to be aware of?

There is a metal bracket (off the crank) that spins around, but will not come off. Guessing this triggers the spark plugs?

19 mm nut / with a size nine allen middle. Both rusted. Do they turn separate directions?

Anyone have an extra cover laying around?

Also, best way to get throttle grip off without damaging controls?

Thanks

If you don't want to reuse the grip, cut it off with a razor blade.

If you want to reuse the grip, pull it back a little and shoot some wd-40
in there. Work it back and forth (I use a piece of coat hanger wire or long thin screwdriver) and the grip will slip off.

Hi Mr. ATX 850,

Welcome back. I noticed an ignition cover on ebay just now, as well as an entire bottom end, a final drive, etc. But that's not the reason I stopped by...

Thanks for the info Cliff.

I'll be sure to check out some of the other mods on your page once I get the bike up and running.

Does the scene under the ignition cover look like this?



(From this page: http://bwringer.com/gs/tdc.html )

In the very center is the head of an allen bolt (socket head bolt, if you prefer). It unscrews in the normal direction, but it's held in with thread locker, so it takes an impact gun or a LOT of torque to break it loose. You can put the bike in gear and hold the rear brake. Make sure you use a high-quality hex bit -- I think it's 6mm.

This bolt holds in the rotor, which is the bit with the tab sticking out at 10:00 in the photo. The rotor is indexed to the crank with a pin, so don't worry about misalignment.

The pickups (triggers) should be 180 degrees apart, and the tab on the rotor should not contact either pickup when it rotates. There's a spec in the manual for the gap between these pieces, but as long as they're equal you're probably OK.

The whole thing pretty much just screws together one way. I think the mounting holes for the plate holding the pickups are slotted so that you can loosen the three screws holding the mounting plate and adjust the timing a bit. This adjustment is not normally needed.

i had no idea that 850's ever used an electronic advance ignition.

Thanks again everyone

A perfect picture to describe what I am looking at. Thanks so much. I wasn't sure which way to crank that thing as there was so much rust.

Yeah, the right trigger and cover got smashed when the bike was laid down. Maybe bent the bolt that spins and makes uneven contact. No impact gun laying around, but I will look for a better allen wrench and some leverage.

FYI, in Austin Texas.

I hope they didn't damage the dowel that goes into the end of the crank and the crank itself. This could be a problem.
