My mate had a honda rs250 which he purchased and rode about 60 miles home with no issues,parked it up when he got in,had a cuppa and went out to fire it up again as the neighbours kid liked bikes. Short story,it didn't start! Gave it to me to fix and compression wise I could turn it over with my hand on the kickstart! Head off a quick valve job and when back together could stand on the kickstart,two prods and fired up sweet,ran like a dream(lol pun there!)took for a nice new MOT and flew through(had about a week left so he asked me to do that as well)so watching you gave me a nice smile as I must be doing something right!

Table spoon of CRC--WD40 in each cylinder and let it sit 24 hrs turn it over with the back wheel a couple of times then more CRC and wait again. Its worth a try before stripping the motor.

[@meeow3rides]

Just a thought to save a lot of work and the customers bank balance how about filling the cylinders with two stroke fuel overnight turning the motor over slowly the next day hopefully the oil in this fuel may unstick the rings also a check of the shims for correct valve clearances to confirm all is good there too and with your fingers crossed and a bit of luck you might resurect this one with a bit of running then a change of oil and filter and everyone is happy worth a try ! saved me a few times on my own machines and you can then do a compression test after it's run a bit to confirm the outcome good or bad . cheers .

[@voyagern]

Just a comment: I have vorked on these bikes for 30 years by now and the wear and tear on this bike is nothing compered what i worked with. And the thing is that they all STARTED and run with no problems. My worst case was with an B2 that had more than 2 millimeters ringgap....but still started with no problems at all, (just burned a halfliter of oil in 30 minutes). BUT...a very common problem who i think is the problem in this case is that Kawas original camchaintensioner is a real pease of shit/crap!! It is not a case IF the tensioner will malfunction, it is just when! This is VERY common!! The thing is that the (extremly stupid kawa made) tensioner trying to grip a oiled steel bar with oiled steelballs! There are NO geras whatever to hold the tnesioner in plase!! Just oiled steelballs to cram a steel oiled rod! Kawa saw this idiocy and introduced the same shit, just with an oilline that added more oil in the back of the tensioner!! (The thought the oilpressure would stop and 1300 engine that would like to backfire!) That did not work either!!! The conclusion on these motors are just the fact that they always jump the chain a halftooth or one tooth so no damage are normally happening to the engine. (More than one tooth always brake the engine but that always never happens), As your bike has low compression on several cylinders I am sure that that is the case here. Check the camchain, readjust it and by an aftermarket camchaintensioner! That is just with an passus: There are more stupid things Kawa constructed this engine with....as camchain rollersprockets in PLASTIC! So this engine cant hold the pressure of many of the aftermarket tensioners! So for many years my solution is that i strip the original tensioner and welds a couple of millimeter of aluminum in the back of it and then drill a hole in it and install a m5 or 6 bolt in the back with a locknut. Just then install it as original tensioner, start the bike, let it idle and the with you fingers just turn the bolt till it seats to the tensioner, lock the locknut. Do this in the spring every year and you are ok! (As i said, im pretty sure this have nothing to do with compression regarding to the cylindres and so on....that is normally impossibbly on these engines, BUT a camchain hopped a tooth WILL get you the result you got!) Hope this would help! Hallen ([e-mail])

[@T.Rathfelder]

That's definitely thé issue voyager describes. Wrong timing due to malfunction of camchain tensioner. That's why every single cylinder is concerned to the same degree. Hope this is now fixed Always good job

Bit sad it being in such nice condition. But bikes like that that have sat best part of 30yrs that have no form of dehumidification, well rust in the bores sealed the rings long enough to get it to start but then the sealing basically went out the exhaust and no compression was the result. I did a GSXR 1100 up a few years ago. Looked great, hardly a mark on it, only had about 45,000klms on the clock, thought it was a good buy. Got it home, new battery, plugs, filters and oil, cleaned the carbs. Hit the button and nothing, popped and farted but wouldn't run. Did all the other things and mucked about for two weeks before I did the compression test. Yeh new rings and hone later and it started.

[@dubsydubs5234]

You can't argue (I'm not I'm just adding to the comments) after a compression test then leak down test but all cylinders showing what looked like exactly the same readings suggests to me timing chain slipped, especially after it was running. I've owned four Z1300's over the decades, still love them.

[@mrbmp09]

I was thinking timing too since they all looked about the same psi. The odds of all 18 rings getting stuck overnight is insane. He can take the cam cover off and easily check timing before pulling the heads. Hopefully the owner will read the comments for suggestions.

[@nounoufriend1442]

@@mrbmp09 But the leak down test proves its passing the rings into crankcase , if it were valve timing leaving valve open on compression stroke it would be passing air out exhaust or inlet ports . Another way to prove its passing rings add some oil into cylinder as it can make temporary seal and restore some compression

Several times in my life, i ran into a problem with rings being Gumbed up and not sealing. If you squirt some oil in the cylinders. Helps get enough compression to get it to run. Just let it run and get hot. When up to temp. rev it through the rev range. Usually, will unstick the rings.

[@simonsackett]

Lovely bike - from a time when manufacturers had mad ideas and just went for it. When you found it had no compression I thought it might end up being every valve bent, or a disintegrated valve gear sprocket or something equally horrendous. Although it's a massive engine maybe stuck rings might be the lesser of many alternative evils. I think I'd try giving the pots a lengthy soak for a few days, then start it with a bit of assembly oil in the cylinders before taking it to bits. Worth a try?

[@phil955i]

[@StephenWestrip]

As I put in a comment elsewhere, if i understood what the timeline he said it was all working and then he stripped it down and “powder coated everything”. Could those specks have been powder coat or paint that got into all the cylinders which is why they all have low compression now? As you said, to go from all okay to this is quite difficult to understand otherwise.

[@kevinwilliams4899]

I suppose any fuel that was injected just got pushed past the rings into the sump? A sniff at the oil filler would reveal rather than the smell of neat fuel at the silencers. As you say though go through the basics Fuel, Spark (present and the right time). Still nothing check for compression.

[@Steve-wx9gl]

Sounded like a real head scratcher at first I was thimking cams good old compression test .Great video and very interesting

[@domkelly1972]

Mechanic here. If you can get to the spark plug that easy then do a compression test straight away. You need fuel ,air, compression and spark and by far the most expensive to fix is usually compression..so do it first. You dont need an oscilloscope as you also can verify fuel presence when you pull the plug. Whats really strange is the guy who owns the bike took off a bank of injectors , relays , ecu and swapped them to another bike , changed the fuel pump and the solenoid and then drove for 5 hours before doing a 3-4 minute compression test .😮. Surely he phoned you to arrange this. Why did you not suggest he do a compression test before he drove all that way? Nice bike though. Maybe he will sell it cheap and i do the engine rebuild😂😂

[@flexjay87]

Such a great example of Japanese history !

[@raymorris952]

Or if you think it's not getting fuel ,give it a shot of easy start into the intake, if it still won't fire you know it's not a fuel issue ! If it pops and bangs all over the place it's timing, if it doesn't do anything then its a mechanical fault, if you have air fire and fuel. Penetrative oil down the bores would of been a good idear before they ran it for the first time, might be worth a try now but probably to late, it will just end up in the sump. Smart move on your end, always check the basics first 👌

What I learned a long time ago is never turn over an engine even by hand that's been standing a long time without plugs out and soaking the cylinders with wd40 or something similar even desel for at least few days then gingerly hand cranking and leaving a few more days before turning it over plugs still out after blowing out solution go for start up if all is well, it can un seize rings and cylinders 😊

i worked for a (UK) bike shop that took a 'mint' z1300 carb model in, it started and ran ok but started to smoke as it warmed up, each bore was badly scored. I ended up ordering a set of oversized pistons and rings from Australia, got the barrels rebored locally and with new gaskets etc, built it back up - very fiddly job, after a full carb rebuild etc it actually ran really sweet - lots of time spent on this one so im assuming the shop lost out on this bike

[@leeandjancruise]

[@firstielasty1162]

Like you thought....I find stuck rings more common than worn out rings. Even occasionally broken or annealed rings (this more on air cooled aircraft engines). But, if the are stuck, I find xylene to work best. From experience, not just speculation. It is a very strong organic solvent- dissolves more goop, and quicker. It is also, conveniently, not very volatile, so it will remain in cylinders a few days. I pour some in each cyl., let sit a few days, suck/blow it out, whup the crap out of the motor on a ride, change oil quick, then. Some oil in cylinders might be needed for the first start, to regain ring seal. The wd40, etc. suggested elsewhere to free the rings is the right idea, but wd is really just light oil thinned with mineral spirits or naptha..nothing special as a solvent. Weak sauce. The fact that it ran, then quit is odd. Maybe light rust on cylinder walls, scraped off and imbedded into old dry ring goop on that first run? Forming a rust/oil goop composite that is just sticky enough to inhibit ring function? Rings can be fickle. The xylene might do it. The cylinders, while not perfect, didn't look too bad. I love these bikes. Was a mechanic at a Honda/yamaha dealer for years. Reluctantly borrowed one of these for a weekend trip and ended up loving it ..constantly running through gears, beating on it, racing friends who laughed at the big barge I borrowed. Sounds great, and is not slow at all. It was fun. Comfy, too. I mean the naked 1300- the voyager is just too big, but still nice.

No compression on all cylinder indicate to me dry bores or even a timing chain problem. It is almost unheard of to have all 6 cylinders with very little compression. It would have been useful to do a wet compression test as well which would serve two purposes. It would confirm that the problem is pistons or bores and it would possibly seal the rings and restore the compression. If there is no difference in the compression, I'd look at the valve timing.

Most likely it's rusted in the bores, that's then scraped off when it was started and ran, migrated into the rings and killed the compression. Hone and new rings if there's no teeth shed in the valve train.
