either steam clean all the oil off or use some chemicals to remove the oil.
so it's dry.
then run it and make sure where the oil is coming from and then decide what to do to remedy it.

I am seriously thinking about renaming this thread to “The Ebola bike” as it keeps seeping fluids from all openings and even through its bare skin. Hope that I have been able to stop the infection now . . . .

I took a gamble and took my oil cooler to the local hydraulic work shop. They were more than helpful when they heard what it was for.

The workshop guy said
- a Gpz 750! That was I was dreaming for when I was riding my 50cc moped when I was fifteen.

Then he asked for some extra time as they were running short in the shop. Not a biggi for me as there was rain in the forecast for the next couple of days.

Went back yesterday and picked the cooler up with new hoses fitted, for 403:- SEK approx. 45 USD.



As far I can see it’s an example of good workmanship considering the welded, used once, throwaway fittings Kawasaki used on the oil lines.



Right now just hoping the bike will deliver as the summer runner I hoped for it to be, then it might just get some of these goodies that I wound on Webike



But now the cooler is back on and I can’t see any oil sweat on the hoses anymore, hard to tell about the cylinder head as the entire engine is glistering since the oil shower last Wednesday.



Now I just want it to deliver so “I can ride the piss out of it” as Steve so poetically writes and take me to work tomorrow. I need to get back home early tomorrow as we Swedes ae gearing up for our midsummer party this weekend.

Nope. No fika this weekend.

Nice going! Those hoses are NICE! I like those AN fitting adapters too!

Where did you read where I said don't open up a 30 year old bike without proper commitment? That sounds like something I would say, I just don't remember saying it around here.

Close but no cigar!

Swapping out the oil cooler hoses stopped the worst flow, but a thorough degreasing of the cylinder head reviled that the sweating from the cylinder head is a little bit worse than just a sweat.

Do I have to tell you that all Swedish bike shops are out of top end kits . . . . . so I am back to my usual task tracking parcels through Europe.

Nessism, I guess that I have been reading between the lines, but I think that the statement

- Don't open up a 30 year old bike without proper commitment?

belonged to 650ED and that yours would be

- Don't open up a 30 year old bike without all the proper OEM parts at hand?

Never the less your message has come through to me and I have learned by my mistakes. The head is not coming off without all the gaskets, o-rings, kawabond, FSM and tools at hand.

I am gambling hard on that the cam chain tensioner parts will be ok. . . . . . . and that the two M8x43 bolts in the cam chain tunnel will not snap on my as they did the last time I swapped one of these gaskets some thirty years ago.

The tensioner is a pretty simple device. You may as well take it apart and replace the seals while the engine is coming apart.

Those cam chain tunnel bolts are finicky. I bought new one's when rebuilding my 750 but they wouldn't come up to the torque value in the service manual. I've got an expensive dial type torque wrench that's properly calibrated too. I've learned to trust my hands when torquing stuff like that so I just stopped turning when it was clear that the bolts were going to snap before reaching torque. Be careful!

In early November I finally got my shit together to take my “The Ebola bike” out to a friend’s garage to change my sweating cylinder head gasket. At that date we had already had a healthy blizzards that gave us a good 15 inches of snow, but as there was no cold the snow melted and gave me an opportunity to ride the bike to my friends garage.

With other mishaps in mind I didn’t get all dress up, first I went down in the garage under our condo, the bike looked good, could see no obvious problem, put the key in and it started immediately. Knowing that it run I switched it of right away and went up to my apartment and geared up. Racing leathers, down jacket, the lot and back down in the garage again.
When I got on the bike and pushed it of the center stand I realized that the clutch lever was not returning! Strange! Put my hand down and pushed the clutch arm with my fingers.

Something didn’t feel right.

That’s when I noticed the trail of little droplets that the bike was leaving.
Shit! after worrying sick this summer that my rusty tank, non-closing petcock, non-closing float needles would soak my engine it finally happened. Even after all the work I had put in trying to prevent it.
Dressed up and all, I rushed to push the bike out of the garage as the leaking now that turned in to gushing. Out of the garage I raced to get the tank of, not too much help as it by now was empty. So I could just sit back and see how the gas/oil was flowing out from under the transmission cover.



Damn I didn’t feel like rebuilding the engine from bottom up, just swap the head gasket.
Our Swedish version of Craigslist has during this summer been littered with all fucked up bobber versions of Gpz750 A1-A3 for cheaps, people has been asking 500 US and not been able to get them sold. So I thought that I better just see if I can pick up a sorry specimen with a running engine, swap it out and then be able to restore the original engine without stress.
So I posted a wanted add, now after running the add for two months I have only had two reply’s and they have both been from owners of pristine original bikes. Not the sorry hack jobs that I been looking for.
Like this one.









Gpz750 A1 1983 12500 US miles (20000 km) first owner with complete documentation.
Slight corrosion on the mufflers, except for that in pristine condition.
I went to see it, mainly because the guy had a spare engine. Unfortunately that engine had just a little too much of the ignition side scraped of in order to be interesting.

So still no spare engine and by now it’s time to tear this baby down if I am going to ride her this summer.

If you see a sorry ass sticking up on the northern hemisphere turned to the east, it’s just me cursing myself for not following Nessism’s advice to stick to Kawa original spares for the petcock.

After being ridden for a few years she went in to hibernation and hasn’t really made any signs of life while I have been riding my FZ750 -85, then today all of a sudden . . . . DANG!

Nice, better late than never...!!!!

Yeah Mick, I don’t know if it’s the new water based paints that takes forever to cure?  Cuz Bobby has had my parts for well over 2 years. 
Back when the paints were thinner solvent his turnaround time has heaps shorter. 
Really looking forward to get the girl back on the streets again, unfortunately the days are getting shorter and we are starting to get sub zero mornings so this season is over.

Looking good! 

That paint looks mint! Love a green unitrak!

Unfortunately, Bobby (my painter) and I fucked up slightly, the decals ended up a little high so the ‘K’ in Kawasaki lettering folds slightly over the crest of the tank.




If life isn’t constant learning, what is it? So we took the weekend of from the workshop and went out to the Stockholm archipelago in order to deepen our knowledge in beer, great food and old bike war stories from the eighties and have now fully recovered and are ready to live the rest of our life with the ‘K’ folding slightly.
