    1980 GS850 resurrection

    I tried to buy a GS1000 from a riding buddy. He didn't want to sell. So instead he gave me this GS850 (thanks Dom). He bought it mainly for parts for the 1000 from a fellow here in Tennessee who bought it from someone who wrecked it in New York. Thankfully since the wreck in 2005 or so it has been stored indoors. I tend to like these ujm's stock or close. But this one has more missing than I want to replace, so Lord willing it'll end up being a mild custom. So far I have shimmed the valves, rebuilt the carbs (including repairing a broken float post), sourced a signal generator and hardware for the ignition, re-jetted the carbs (already had pods, but stock jets ), bought decent pods (APE) to replace what it had, and drained the oil pan, replaced that gasket and the stator gasket. I also bought REAL gaskets for the cam cover and breather cover. She runs but isn't charging.

    I have three stators two which are oem but have ohms readings of about 11, so they're evidently bad. There is also an aftermarket one that looks great, but in all the moves around one of the leads was broken. I'm going to look at repairing that and if not may try my hand at rewinding one of the oem's. I have a busted up tail section. Another one off of a 750 that also is busted up. But I have a tail section off a Z1 that I may try and graft on, yes I know sacrilege . I have one side cover that's banged up, a king and queen seat, and an ugly rattled canned tank with a good sized dent. I'm pretty sure that the speedometer isn't stock either as it has no fuel gauge.

    I'm looking forward to getting her going again. Probably will be somewhat of a slow go. I appreciate any comments as I'm going.

    Anybody know what this speedo came off of?

      Almost forgot, I have a broken exhaust bolt on the #3 cylinder (and yes the one behind the frame). I've replaced the other bolts with studs, but looks like I'll have to pull the head to get the broken bolt out. It's flush with the head. I also found a center stand and put it on to replace the one that was missing. Gonna be fun!

          Hi My name is Josh, i'm new to this forum...

          i'm rebuilding a 1979 GS850 and i want a new exhaust system but the only aftermarket system i could find is a MAC 4-1 that i don't like. they also biuld a 4-1 system for the 750 that looks better but it says it doesn't fit 850s. the 850 system specs says it fits 1979 GS750 and 850. i saw on pipeburn a 1979 GS750 with that same system i want, my question is will it fit my 79' GS850 is there any difference? anyone more familiar with these frames?
