82 GPz750 keepin' it real,.. for now

Once adjusted they can last for a few thousand miles. In your case, you might want to recheck them after 500 or so to make sure and adjust if needed.

Mines in itty-bitty pieces some of which are still stuck to the head and cover. I have a OEM on the way. I'll use silicone so it will last me a bit.

I got my drilled rotors on eBay. They were fairly cheap. Pics of you rotors?
Steve

I've been looking at the ones on eBay, JC Whitney has good prices too.

I got these pics and on further examination they actually don't look too bad, I used some calipers and they are about 0.198" I wish I had some blade mics for getting a better measurement of the low spots.

0.198 works out to be 5.04mm. Minimum thickness is 4.5mm. They look good. You might put in new pads and run them like they are.

Sounds good, I'll throw new pads on when i get the tires replaced....

Quick update. I rebuilt the carbs over the weekend, I couldn't get the screws to come out of the mounting brackets so i rebuilt them coupled. They weren't too dirty, the PO said he had cleaned them out not long ago. 3 of the drain plugs were sized and/or stripped to where I couldn't get them out so I left those alone too. Some of the pilot jets were in tight enough that someone in the past had nearly stripped out the screw slots. That's as far as I've gotten at in actual wrenching. I'll do the first round of shim swapping here when i get a minute. I know I'll be doing it at least 2 times..... I am still waiting for the cover gasket and instrument cluster anyways.

I went to a local bike salvage today and had a look around, I was looking for a project seat but didn't find a KZ seat but i did find a ZX seat that looked like it might actually fit except for the up swept tip on it. I wasn't sure so I left it. Anyone know for certain? I'm going to alter it anyway so if it will fit by just removing the front part I'm game.

Having the worst case in mind I asked the guy if he had any heads for the 82 GPZ750s. He said he's had a few go through so there should be some engines in the lot somewhere... we'd just have to go through them. That I took as good news, I'm sure not many people hear that when looking for parts for this bike. I'm thinking maybe i should pick up an entire engine for spares and rebuild eventually.

If the price is right get it.

I just might but I'm in no hurry. I'm not sure I'd be able to ID the correct engine anyway, besides being painted black.

I always had spare parts on hand until the Meth Heads discovered them. My fault, I should have protected them better. Those parts would be worth a lot of money now. They also kept me on the road for many years. Nice to have valves etc. in case of a break down.

Another setback. I was swapping out the shims on the exhaust valves. I decided to do the exhaust and then the Intake. Everything came out great and I put in the prescribed shims in 2 & 3 and 2.00 shims in 1 & 4 so i at least know where I'm starting. I then placed the cam shaft back in position and started to refasten the cap bolts nice and slow in an alternating fashion. Just as I was starting to register some torque on my wrench one of the bolts snapped! I started to drill into it for an easy out but my drills stopped biting, Not that I know where my easy outs are at the moment, besides I'm sure I broke the small one last time I needed them . So I stopped trying to drill on that bolt and looked at the other bolt for that particular cap. It definitely looks stretched. So I packed the bike back up and now I need to get an easy out and drill to get the busted bolt out and order a new set of bolts as well. Anyone know the best place to get a set? I did find the factory part # 92001-1109.

Another wonderful thing... when I took the right side cover off to get access to the timing marks I noticed the lower screw wasn't there. It seems the lower thread boss and a chunk of the housing has been totally broken away. It looks like there isn't much remedy to that except a lower crankcase replacement. That spare engine is looking better now even if i just start swapping parts back and forth.

What did you have the torque set at on the torque wrench? Ed

I use oil on my drills. I was taught that in metal shop and I was a Machinist for a short time. (drilling out punch tailings on SS Allen head aircraft bolts. Thousands of them.) :sick: The oil keeps the bit from overheating and helps it in cutting.
The cases are milled as a set. You can't replace just one side. Better off having it welded, drill and tap a new hole.
