Minutes to do the actual adjustments.
Hours to get to the valves, and put everything back together once done.

This is so prevalent, seems every EX I service, extremely tight exhaust valves are encountered....some right down near zero. Very concerning.....even present on checks with mileages under the suggested maintenance 7500 mile.

Other than Kawasaki using swiss cheese for the exhaust valve seats...can anyone offer explanation?

@Saabnut and @bpe do you guys find the valve train stabilizes at higher mileages? Or do you continue to find tight exhausts the whole run up to 100K at every 7500 mi clearance check?

Generally speaking I have found that the higher the mileage, the less they need to be adjusted. Several times not moving at all from the last time they were checked. But, and this is a big butt, the only time I had valves move completely out of spec (and by a large margin) was when the engine had about 60,000 miles on it. Judging by when the bike started running (really idling) funny, it happened somewhere around 4-5 thousand miles after the previous adjustment.

I think the lesson here is:
Always adjust valves according to schedule. But if you run into running issues that could be symptomatic of valves out of adjustment, don't hesitate to go back in early and check again, i.e don't just discount out of spec adjustments as a possibility, only because you know they were done less than the 7,500 mile interval.

My only advice is to take your time, if it takes all day it takes all day. Some advise removing certain parts for access, some dont. I did find removing the 8mm bolts and oil pipes once inside made things more accessible. I guess we are luckier here not having to deal with the emissions plumbing too. A friend of mine once quoted that those lock nut and screw type valve adjustments only ever get loose over time. How very wrong.

I usually spread it out over days, even though it only takes hours. I prefer to keep it in "hobby mode", if I work too many hours on it in one day it starts to feel like work. I don't want it to feel like work. This way works good for me, but it is not for everyone.

about 4 hours here...I dedicate (and plan for) a half day. With no rush...the Pair valve hoses (epa stuff) simply unplug. Speaking of which....changing the spark plugs and cleaning the cap innards as its needed to rotate engine... air filter, battery inspect/charge while I'm doing it. The whole related area, as I'm sure you guys do too.

************************************************** ************************************************** ***

Where the hells' all the support when I was doing the electrical cleanup (nightmare) on the Triumph 675? Still in process but almost there, looking mostly neat and tidy again...and I'm down to only 1 OBD code from 12! Fork seals and LED turn signal install and desperately needed associated re-wiring to follow. The PO kids made an unbelievable electrical mess o' this thing. Thankfully the throttle bodies, spark plugs, engine components, etc were largely left untouched. I don't want to imagine what they would have done. Thread with pics in Northeast section Long Island service thread.

When complete the owner will register and get NYS inspection. It should pass and be one fast little street bugger.

Same as bpe, I've found the valve train to stabilize after the 3rd adjustment, so after about 20,000 miles or so. At that point, I can get 10,000 miles out of an adjustment, though I never push it farther than that, even though it's not uncommon to find all the valves to be within spec, albeit very close.

As for advice on doing the whole job, the best has already been given: take your time. Also, do it right or do it twice. Cutting a corner off one procedure will add two corners elsewhere.
I, personally, can do the whole job in 2 hours with a beer in one hand. If it is your first time (or even second or third), you'll need to budget WAY more time than that. It takes a lot of practice to know exactly where everything is, what tools to have on hand and to have the clearances memorized.
Lastly, if you think you did something wrong, you probably did. Double check your work. And for the love of god, make sure the two dowel pins in between the valve cover and head are accounted for. If you are putting the valve cover back on and can only find one dowel pin, find the other. The most likely place for it to fall is inside the engine and will render your valve adjustment moot in a hurry if you fire it up.

Leaving the spark plugs in place until the cam cover is off isnt a bad idea. Had one dowel in the cover and the other stayed in the head.

A habit I got in to after dropping a coolant pipe bolt into the combustion chamber. Luckily, it was on a used engine I had bought to put in my bike, so I just flipped it upsidedown to get it out.

Also, a good way to ensure the dowels are never lost is to JB Weld them into the valve cover or cylinder head.

I added a drop of Loctite to the dowel holes before placing them back in the head. I figured there was a preference due to gravity if they decide to set themselves free again.

Had a friend lose a dowel down a customers spark plug hole. Yes the head had to come off in the end. His voice was ringing in my head whilst disassembling the bike.

Gradually converting my 1993 Gen1 to stock condition.

Bike had been stripped of all decals - reapplied some Kawasaki signage.

The "500" stickers are for a CR500, but I trimmed off the "CR" part and I think they look OK.

Hats off to ya'....very nice job

The general task of bringing a neglected EX back to "late model classic" a very sound idea, a project to be proud of when completed.

Just like you're doing..... my brother in Florida has restored a couple of Gen 1's, over time, slowly, step by step......all the bells and whistles...updated flywheel, gearbox, CT tensioner, carb refurbs (done by yours truly), paint, decals, I forgot the rest but they came out really nice. He's still got one, but sold a '92....dunno why, but it was the best running EX I've ever encountered.

Not today but this week, fitted ex300 rear shock, rebuilt forks with new seals and sonic springs.
Replaced front indicators with some led units (storm tipped bike over on driveway a while ago).
Then found the battery had died while it has been in winter storage, so haven't test ridden yet.
But it passes the bounce test when i sit on it 🙂

Did the 4k tune up. Plugs & filter. Should carry me into winter break down.


The EX tune up takes priority over any yard work.


Oil change coming by late next week, Sunday at latest.
Yard work will still be waiting at that point also.

not today but a couple days ago...not EX but on my Honder CBRrrrrr :

*check, adjust tire pressures
*check engine oil (level remains stable since the 600 mile change)
*check chain tension (within spec)
*clean, lube chain
*clean using Honda spray polish and microfiber cloths
*install Speedo Angel brand instrument panel protective cover

1900 miles and no issues whatsoever, impeccable

Last night I replaced my rear suspension with that of a 2011 Ninja 250, and flushed the coolant. Currently working on a deep clean of the radiator. Hopeful to be done tomorrow with that. Almost time for winter maintenance to start.
