Welcome back to our channel, everyone! In today's video, we're diving deep into the heart of our resurrected 1983 Kawasaki GPZ1100. If you've been following our journey, you know that just three months ago, we managed to unstick and revive this sleeping giant. Now, after roaring back to life and logging in an astonishing 3,000 miles, it's time to see if our efforts have left any lasting impact.
Armed with our trusty borescope, we're venturing into the depths of the cylinders. Will the ghost of a long-abandoned engine return to haunt us, or did our mechanical resurrection breathe new, sustainable life into this beast? There's only one way to find out, and we're taking you along for the ride.
In this video, we'll be providing a step-by-step guide through the inspection process. You'll see firsthand what we see: the glimmering piston walls, the tops of the pistons, the exhaust and intake valves - every nook and cranny of this vintage marvel. We'll be pointing out signs of wear, possible damage, and anything else that grabs our attention.
So buckle up, motorcycle enthusiasts and curious minds alike! Whether you're a pro mechanic, a backyard tinkerer, or just love a good mystery, this deep dive into our GPZ1100's cylinders promises to be a thrilling ride. Join us as we uncover the secrets hidden within this classic bike's heart, and let's see what the road and time have etched into its metal.
Remember to like, comment and subscribe if you enjoy this video. Your support helps us keep the lights on and the engines revving. Until next time, keep the rubber side down and the spirit of adventure alive!

Really surprised me when it started but they are pretty bulletproof engines, I have a z650 and I had an old gt750 which everyone rode for years, had little to no maintenance but just kept on going! Great bikes.

@rosewood1 Год назад

Some vertical marks in no.3 but pretty light at this stage. Could be a frozen ring or a broken ring. Ride it gently and see if it gets worse. If it does then I would pull it apart and fix because the rest is so good. I have found that preventative maintenance has saved me big time. During COVID I built a new Austin Healey 100/4 engine. Started with bad exhaust valve and then found many issues. But in the end I preserved the crankshaft journals the cylinder bores despite broken rings camshaft etc. So new bearings rings pistons timing chain guides etc And I now have a brand new engine that will really last.

That is such a great point. Since we are never getting rid of this motorcycle. We have lots of big maintenance planned. Probably in the winter ❄️

I had one of these bikes. They don`t like after market pipes. Guys who did went with smooth bore carbs. After about 30,000 miles, I would the DFI light when the bike got hot. It went into a limp mode. I traded it in on a ZX-7.

@firestorm755 Год назад

It's not bad is it! There's still some crud at the top of the bore and the back of the valves look a little dirty but other that that I'd just leave it alone. That's one amazing engine. Out of interest have you done a compression test after your trip? The rings will have freed up and the valves cleaned the seats up, you can see that.

I did 210 thousand miles on a Gt750 p4. 50 k miles on its brother. About half a million on 9 different gt550's and about 100k miles on a GTR 1000. Kawasaki spent the budget on the mechanicals. The engines are bullet proof, whereas the drive shaft shoulders are not horse shit proof. Where they skimped was on the brakes, suspension, and cheap electronics, specifically the safety switches and the R/R. You can ride these bikes through snow drifts. But dont expect it to start the following the following day as the melt water infiltrates the electrical connectors. Specifically the ignition igniter box connector and the ignition barrel. Marine grease works on the i.c connector but the ignition barrels all need regular wd40. Good luck. Beautiful bike. Well done on saving it.

@jameshisself9324 Год назад

'Ruined' is such a strong word. Have you done a compression test? It doesn't matter what it looks like if that is up. I suspect it won't be though. It really needs a case split and the gearbox and bottom end gone through. Any water in the gearbox usually means it needs new bearings. It won't 'not work' but it will fail long before it would otherwise. Same with the bottom end, only much less likely. The volume of water that came out of those cases indicates the water line under the oil was high enough to get into the crank bearings, then it just depends on how far in it seeped and for how long. Still worth the price though!

@jameshisself9324 Год назад

I left it out since it seemed obvious- top end rebuild with valve job and seals, rings, pistons and a light overbore. Check valve guides for scoring and if so replace those as well. Inspect everything and replace anything out of spec. It will be even faster!

@motorcyclerewind Год назад

However sitting outside a decade perhaps and to remove 5 litres odd water and emulsion To drive most of 3000 miles 😂 My utmost respect sir to you and the 1100. Was the electronic ignition shot or what was the issue at the end? Keep an eye on the earths. Sand tjem and cover in grease. Learned the expensive way.

@motorcyclerewind Год назад

Thanks so much. This is the BEST motorcycle ever made. Keeps defying the odds. The issuer in the end was a simple one. The right coil for cylinders 2&3 vibrated loose and was shorting out. Since I have found and fixed we are all good. Looking forward to the next adventure. Thanks for watching.

@gordonmerrilees5846 Год назад

Cylinders look surprisingly good and if it gives good power without smoking, surely a great result. However, what about the crank and gearbox bearings? So much water came from the sump, you can only imagine the corrosion in there.

@motorcyclerewind Год назад

That’s what I thought. I scoped the bottom end and it looked awesome. When I pulled the clutch cover off I expected to see loads of rust. It looked brand new. I know with the amount of water that came out it should sound like a bag of marbles in a dryer.

@jameshisself9324 Год назад

@@motorcyclerewind Not necessarily. Premature gearbox shaft bearing failure is likely though. As they go they get sloppy and cause excessive wear on the gear teeth and shafts. Better to pay just for bearings and seals now than try to find gearbox parts later.

@kalaharimine Год назад

After the hell that motor went through, It's a miracle! Suggest you check compression with a guage to see how healthy your rings and valve seating is. Is it using an appreciable amount of oil?

@motorcyclerewind Год назад

Agree. I believe it has earned a top end refresh this winter.

@walterwolf2027 Год назад

The ZX1100A series was prone to early cylinder wall glazing due to being run at low rpms over extended periods (coz where can you really open these beasts up regularly without losing your license?). Symptoms of the glazing syndrome are low rpm oil burning which is super obvious from the smoke in the exhaust gas and the stench of burning oil. I don't see that in your bike at all (both of mine had this issue and I had it resolved). Given that you're not seeing this, and you don't intend to ride it like Ghost Rider, I'd be tempted to chuck a compression tester on it and if all the cylinders come out somewhere similar, leave it alone and nurture the old girl.

@motorcyclerewind Год назад

We did check compression when I was in St Louis with BJ. Can't remember the numbers. I can do it again and put the results in a post. I also want to take it to a dyne to see its horsepower numbers.
