Things started off pretty bad, clutch cover had been left off, the basket had been laying in the weather for who knows how long, carbs were frozen along with one being partially disassembled, front brake master was seized, clutch master was seized, lots of parts missing, wrong rear wheel assy. But what worried me the most was the engine was seized up, someone left the plugs out.

After cleaning up the top end as best as I could without tearing off the head. Took off the left cover and gently rocked the crank back and forth until she broke loose. Rinsed her out from the intake boots then from the exhaust side while rotating her with ATF, diesel, and gas. The valves are actually sealing again on all but the intakes of #1 cyl. and they're not leaking too awful badly. But I'll know more once I do a leak down.

Wow that is some serious corrosion. I think the other concern you may have is if water sat in the cylinder the bores are probably toast. happened to my 750

Yes sir, I'm hoping that's not the case but we'll find out and if it is then it will have to be addressed sooner than I would like, but more than likely it'll have to be at least bored.

Figured I'd upload few pictures and post a update. The head has cleaned up better than I expected, it's making good vacuum at the intakes when spun over. Got another set of carbs the other day, came off a buddies early 80s model Kawasaki 1000 Police bike. Hated to pull them off such a nice complete bike. They look to be 34mm and are round slide but are in really good shape. I'll use these until I can get the flats slides sorted, only thing is they came with 127.5 mains and 37.5 pilots. I don't have any bigger for those, might have to drill out the jets instead of buying new ones. I'll post some pics of them later couldn't believe they were in such good shape.Went back to where the gixxer came from and found a few more parts. The clutch frictions made it now to find some steels.

Well the carbs I pulled from the Kawasaki Police bike have a little different spacing and the throttle shaft where the cable attaches is a little too close. Got a Yamaha outside I might try it's boots to get them on.

I need a slide, needle, spring and mixture screw for BST 34mm flat slides. I have an old Yamaha the boots on it look to be long enough to get the round slides on, might try those.

Got a set 34mm flat slides off ebag along with ignitor, throttle cable, handle bar grips and throttle tube. Bike is firing and belching flames, as soon as I'm done with a friend's vet I will run the valves and reset the clearances. I'll add some more pics later when I have time. Y'all keep your powder dry.

Got the valve cover off and it seems most of the rockers are to tight, it's been trying to crank but it's low on compression.

Got her busted off, but won't stay running. But I'll get her going.

Hopefully I'll get a chance to work on her today and figure out what's going on with the fuel.

I might consider rebuilding the carbs or at least a total disassembly and deep clean. If you get it running, I'd idle it only and change the oil and filter after a few minutes. God only knows what junk is in that oil system after sitting so long. Keep up the good work! I like reading about the progress.

Yes sir, I tore them down and the slide guides are pretty bad along with being seized along with some other things. I had to find another needle to put in the place of the stock one that was missing until the new one came in. Got some more carbs that were about as bad as the original ones, one of the needles in one carb was half corroded away. Another had pits in the needle. Seized up and corroded badly but 3 of the slides and guides look good so now I've gotten them freed up I will mix and match the 2 sets together lol.
You are absolutely correct sir in the assumption of there's abundance of nastiness in the motor, I've flushed it four times now, once when I put the clutch cover on filled her with diesel and left her to soak for a few days. Drained that, filled her again with diesel and ATF un seized and spun her with the starter I drained that, then filled her with 50% motor oil and 50% ATF while I was flushing out the head and valves then I drained that replaced the oil filter and refilled her with Rotella before putting the carbs on. The oil is already brown again. Still waiting on 6 clutch steels to get here, I plan on dropping the oil pan and cleaning it up also as it set with the clutch cover off for years. Sorry for the looong reply but I wanted to document what has been done so far so I can keep up with it.
