It is scary. Wait until its time to fire it up and you are listening for the sound of valves bending :-\. It will work out.

Yep. First time I rebuilt a Z1 motor many years ago I  had the cams out of time. I was turning the motor over at the crank when I heard tink, tink, tink. It was all over but the crying, Worse part was I didnt have headwork done when I had the valves replaced.

If you recall, I did express some minor scepticism on getting this done in one day, my friend.  All my valve checks were done by the Kawi Tech at the dealer.  Based on anecdotal evidence here I wouldn't have touched that job with a 10 foot pole.  Good luck!  On the positive side, once this has been completed, you probably will never have to check it again.  My current ride tractor fringe-bike has hydraulic lifters...no valve checks ever again for me.   ;)

I discussed it with him this morning.  He said:

"Measured per manual, which is not my normal method.  I prefer to measure directly on the center of the cam lobe heel. This means setting the crank at 90 and turning the engine four times (180), doing one set of intake and one set of exhaust per. The manual gives the more common way of setting the crank at TDC and doing two sets of each with the lobes canted 45 over. I did check to make sure the lobes were in the correct position each time."

 

And I would add:  It is highly unlikely only two of the measurements would be "good" while all the rest being "bad."  And since the exhaust seem far more close to spec than the intake (except one cylinder) that tends to indicate it is not a systemic methodology error.

Max, you would get a kick out of adjusting the solid lifters on a 1969 DZ-302 motor. Running, idling engine at 195*, valve covers off, oil flying on the smoking headers, and working with feeler gauges as the rockers are moving up and down in a blur :o. I love that engine, but really appreciate the modern hydraulic lifters..

Yeah, this is just a ridiculous amount of work for a "maintenance" item, at least on a bike this complicated and packed with stuff.  This makes me want an electric motorcycle even more (if we can just get the battery technology there- we have a pretty long way to go, still).

Shims should be here Wednesday.  We are still trying to figure out how to fix the engine mount.  The attempt to drill out the bolt has failed- it is impossible to center the hole due to the bold surface being so uneven.  My friend has some ideas still.  And we are both still very sore.

I feel your pain. When I adjusted the valves on my C14 about 4 years ago it was a true stressor and took a lot of time. At 28k miles, 13 out of 16 valves were slightly out of spec; adjusted them all to the high side of spec range. I am not a mechanic and this was at the limit of my mechanical abilities. But at least when it was done I was certain that all valves were adjusted properly. I was fearful of what would happen when it came time to start the engine, or if the engine would even start. It was a great relief when it started and ran well. But I will never adjust the valves on this bike again. Never. Ever. Best wishes for getting the job done.

That is my sentiments to. Pressing that starter button the first time was hard!

So how long have you been on this forum reading valve check/adjust posts?  Let us know when you want us to call you Haroldo... ;)

but...
Haroldo basically did his own work..  a didn't a pro mechanic helping him... Max has like 20 of us, and needs some cheese to go with the "whine"...

just kidding, and in my usual friendly manner... all good... get a hand grinder and grind the end of the broken bolt down flat, then use a center punch, to make a good "divvet" in the end, drill the sucker, and use easy-out to remove...


then, while the bike is "sans-tank", remove and replace that gacked up fuel filter... trust me, it's gacked up now... and will haunt you later............

Unfortunately, it is broken further in, so it can't be ground flat... yet.  My friend is making some kind of jig to see if we can get a straight shot with an end-mill type thing to make it flat enough.

It won't be easy.  It broke because of the unbelievable amount of torque we had to put on it.  But we are hoping with heat and such, we can get it out.

That was on my "maybe" list.  The problem now is that the tank is half full and sitting on its side (and isn't leaking for some reason).  We expected, when it was de-hosed, it would spew gas, but didn't.  Also don't have a filter (and too late now to get one, probably).  I suppose I could try to clean it, though?  Assuming I can somehow get enough gas out of the tank to remove the assembly.  On my old ZRX, it was easy- just turn the valve to empty it, close it to keep gas in.

the fuel line contains a check valve, preventing fuel loss when removed... trust me, I did mine just before the national rally this year, and using a BIG funnel, open the cap, and invert the tank over the funnel to remove the fuel.. dump it into your car.

then, when done lay the inverted tank on it's side, and pull the pump, and do the filter... It's very easy.
you don't need to "order one", they sell them at pretty much every Kaw dealership, it's used on about every fuel injected machine Kaw makes.. they are always on the shelf...

49019-0013... should be in stock at most Kaw ATV dealerships..

go over to the COG site, there are a lot of directions for the job there...

He first cleaned out the casting ridge that was inside the mounting bracket, making it "true".  He then made a special tool by drilling out a bolt that fits inside the engine mount bracket, with an inside diameter that fits a 5/16" tool and dropped that off today.  The theory is that if I can get the engine to align with the hole (which I am not sure how I will do that and keep it there) I can then use an end-mill bit through that special tool to reface the broken bolt.  Then switch to a 5/16" drill bit and drill through the bolt, using the tool to keep the bit level/straight.  Then we can later use heat to destroy the threadlocking and then back the rest of the bolt back out using something like an easy-out.  I hope to attempt the drilling part on Friday.

Also, the shims arrived today, and are the correct/ordered sizes.  Hats off to Rocky Mountain (ordered on Sunday with "standard" shipping).  I hope we can attempt to use them Saturday afternoon.

WOW...I have done valve adjusts on every bike I have owned that needed it over the last 50 years but I will never do one on my C14. I rode mine to Texas (1,300 miles each way) and had Fred Harmon do mine and it was so worth it....especially when I see your pictures. You are a better man than I am. Mine was done at 46,000 miles and he replaced 12 shims to get them all at center but if I remember correctly only 4  were out of spec. 16,000 miles later no leaks or problems of any kind and runs perfect....my wallet is a little lighter though. Two days in a hotel watching TV seemed like more fun than taking on that job. JMO
