Question Valve adjustment check

I have a workshop manual and have been trying to find the procedure for checking the valves. I know also there should be tolerances on the shim that your checking. My 04 919 has 15,800 miles and I need to do the 16000 miles service. I also want to do the starter valve syncro while I have the bike down for maintenance. I have been able to find that. Any help with locating the procedure on the valves adjustment check or advice will be highly appreciated.
One more question, about my oil. I have been using Honda GN4 10w-40 SJ since I bought the bike new. I bought a 2003 Kawasaki ZRX1200R and the original owner was using Castro Syntec 10w-40 synthetic. I stayed with that oil on the ZRX. I was thinking of switching my 919 to the Castro synthetic in order to have both bikes on the same oil to make things easier. Okay or a mistake? Looking for advice from some guys with more experience than me. Thanks alot!

THe oil part is easy....any synthetic is good for the motor, dont believe the hype about "burning" up your clutch.

Usually when checking valved you want to bring that cylinder your on to TDC of the Compression stroke, that means ALL valves are closed and you are able to check the tolerances, that the book should have, if not GET A FACTORY MANUAL.

I do not know anything about a starter valve synchro...dotn know what that is to be honest with you. I have done valve adjustment on my 600RR and many of my cars. Good luck alot of guys here are VERY mechanically inclined

I was concerned that having run the motor on conventional Honda oil for 16,000 miles and then switching to synthetic might cause problems. I was hoping it was okay to do that. I ran into someone who had a 2001 FZ1 with 102,000 original miles on their bike. They showed me the odometer. Digital odometer. The person bought the bike new and had been running Mobil 1 synthetic. The valves had never had to be adjusted and they have never had to add oil between changes. They changed the oil every 3000 miles. A little expensive, but still riding the bike with no problems. Clutch change and fork seals. The bike looked great!

Check section 3-7
That is, chapter 3 (Maintenance)
Section 7 (Valve adjustment)

(if it's the Honda Service Manual you have.. it sounds like it)

Not meaning to sound nasty or put you off having a go, but if you need to ask the question, you may be better off getting a service shop to do it for you, as the valves adjustment is shim based and not merely adjuster screw based.

Now for a display of my own ignorance, what the hell is a starter valve synchro?

Valve adjustment- Checking the tolerances is the easy part. More than likely everything will be okay. However if any shims needs to be replaced the cams will have to be pulled. Are you up for this level of maintenance? It's all spelled out in the factory shop manual.

Starter Valve Synchro.- This is similar to the synchronization procedure we perform on carbureted motors. You need a multi Hg (mercury) monometer or a Morgan carb. tune. Once again, are you up for this level of maintenance?

Oil- Any synthetic oil is acceptable as long as it does not have the energy conservation logo on the bottle or jug. Treat your 919 to the best, we are running a group buy on Repsol. https://www.wristtwisters.com/forum/s...ead.php?t=1212

Aaahh.. I see.
Oddly enough, I always simply refered to it as "balancing the carbs" , and when someone looks at me odd, I've just said to 'em, "you know what I mean"...
Mind you I've never actually performed the job myself.

bloody amateurs

I use Motul 5100 15W-50 on the street every 1500 - 2000 miles

and I use Motul 300 15W-50 Synthetic on the track ( I think that is the weight of the oil)

Never had a clutch problem

I have never performed this job on my bikes, but I have helped my friend on his ZRX. I was aware that there were shims that you will be replacing if the adjustment is out of tolerance. To answer wether or not I am up to this work is probably a good question! I feel if I can look at good directions, I will be okay. Especially having my ZRX friend there to supervise. He is experienced in balancing carbs. Thanks

Thanks for the info. I probably need adult supervision. Thanks
