Careful when doing valve clearances, Haynes manual sometimes if diff to Kawasaki service manual. Early Z's you did the clearance with the lob facing away from the valve (valve fully shut) Kawaskai modified this to do it as follows With cyl 1@ at TDC of the power stroke, measure the clearance on intakes 1 and 3. With cyl 2@ at TDC of the power stroke, measure the clearance on exhaust 2 and 4. With cyl 3@ at TDC of the power stroke, measure the clearance on exhaust 1 and 3. With cyl 4@ at TDC of the power stroke, measure the clearance on intakes 2 and 4 Kawasaki FSM procedure shows that Kawasaki deliberately chose those crank positions, and valve pairs, so that a clearance would only be measured if the adjacent cam was slightly pressing on the valve. This would ensure that the camshaft was lightly pressed upward, thereby removing any slop in the measurement, making it very repeatable and consistent. With these shim under buckets you can get them withing 0.01 of where you want it. Always aim for the middle of the spec. Also read the bit about the cam chain tensioner with the cam cover off. I think it has a ratchet mechanism so you could overtighten the cam chain if it is left in with cam cover off if there is only a fixed blade on the roof of the cam cover. As Del would say "you knew that already"

Thank you for that matey, very kind of you and I didn't know that as I've not read that bit if the manual yet. I've got access to a workshop manual as well as the Haynes for reference and will be using them both. Thank you for chipping in matey 😁👍

I'm not an engine builder, but when I rebuilt the cylinder heads on my projects, I put it in a plastic storage box with loads of washing up liquid and the hottest water I could bear. I washed it and then blew it it over thoroughly in all the nooks and crannies with an air line. The head being nice and warm appeared to dry completely and quickly due to heat from the hot water.
@QuickBikes
@QuickBikes 2 года назад
That would make sense... I was tempted to get the parts washer on the case, but give how stuff flash rusts in here once its been decreased, decided not to preasure wash it etc. Sis you have troubles with inserts etc rusting or no?
@aspectcarl
@aspectcarl 2 года назад
@@QuickBikes no problems at all, I had thick rubber gloves, once the head was on the bench fresh out of box and gloves with water inside removed it was still dicey touching the still hot head, blew it dry, run some oil down the valve stems and wrapped the head up in workshop blue paper.

14:58 I’m in the same boat. My trials bike would only go into 1st and 2nd, so I’ve stripped everything off it and I’m rebuilding it, full nut and bolt. It’s only a 2 stroke though, so not as in depth but still new to me. I also watch Matt and learn loads from him but also yourself in your approach. Keep it up mate, it’s a great watch 👍🏻

Give the head a good wash in detergent or diesel and jetwash it out to get the most of those wire brush tails out, then air line it. when spraying with the brake cleaner do it over a clean bowl (washing bowl is my fav) and see if you have any more bits of grit come out. Pay particular attention to all the threads on cam caps as well as oilways. keep oiling the valve guides if using water to wash out. That glass plate comes in handy to clean the faces of the head and cam cover. Straight edge on the head and barrel to check for warp. Have always preferred to use Genuine Kawasaki head and base gaskets and also genuine valve stem seals over pattern one. ~You have done a great job on that head

noticed you mixed up the valves. I pop mine in numbered compartment so it is less to grind in and keeps them mated up with stems as well as seats. also valve clearance wise. Have found a soda blast works great on carboned bits with zero damage.

Just put the valves in to protect the valve seats, then remove rest of the carbon. And last use compressed air thru the oil galleries, very important. I don't know about the zzr's but I can only see turbo potential in this videos and 150 mph power wheelies 😁

You can use a heavier steel brush and die grinder air tool, to clean all the "scale" in the exhaust ports...The head is made of pretty tough ally and won't get damaged if you use common sence..ANY pitting on the mating surface of any valve, throw it out and get a new one!!..You will not be able to remove the pits with "lapping compound"...Insert valves into valve guides and "wiggle" If you notice more "slop" on any particular valve..replace that valve guide...It is really nothing to go ahead and using a "rotary burr" clean those " casting marks" up in the intake and exhaust ports...makes the engine run SO MUCH smoother and increase's power..(takes very little time and is simple tk do)..Don't try your luck at cutting "port angles" until you have someone to show you how ( You cut metal out of the "top" of the "port runner" and not the "ramp"...You can also cut the "port openings" the same on the head at intake and exhaust. ..or "match the ports" as it's commonly called..HUGE performance upgrade!!...It is probably worth taking the cleaned head, valves, spgs, keepers to a Kaw shop mechanic and have him Grind, seat (lap), check spring pressure's and assemble the valves into the head..Looks like it needs it with the "scale" in the exhaust ports ( probably run on regular cheap fuel) considering the "pitting" you talked about on the valves (exhaust I bet..lol)..That Kaw engine loves High Octane fuel / race gas and will run much cooler and cleaner with good fuel..Lastly make sure and check the "valve rocker" mating surface and contact area on "valve stem" for ANY wear!..This has always been a weak part of that engine (and why I said to carry head to a wrench with tools and experience for the actual "valve job".. and valve assembly..I'd go ahead and have him set up the "valve clearance" and "spring pressure's" just because of the Patriot hassle to do it all without head machining equipment and tools, plus a "shim assortment" ..It would get the head "right" and save a LOT of time in the build...LOL..Just my 2cents..lol..It's gonna be a nice bike!!..Frame's a bit to long..(I like putting that engine into a "600" frame! .Oh boy does that make a fun bike!!..Your gonna due fine and you are already knowledgeable enough to build the bottom end..you just need to watch some one do it!..The HARDEST and most important part of the rebuild is building and setting up the HEAD!!..That's what makes all the powernin that engine!!!!!..Have fun 👍👍👍🗽🇺🇸

Mate... LOADS of good info and I'd love to donit all, but I can't.... it makes sense just give the head to an engineering gaff and get them.to do it, but to be honest it would cost more money than I have spare, and I wouldn't learn anything if somebody else just did it for me... Yes they would do a better job I'm sure, but I do like getting my hands dirty o stuff like this. The project has definitely got some interest behind it and I'm itching to get it done, so the money I have needs to go on things the bike needs rather than somebody else's time if that makes sense. I get where you're coming from matey, but Jamie is confident that we can get it done 😁👍 If only I was richer hey 😁🤣👍
