well, she rode to college today so I'm anxious to see if her cam chain is making noise when she gets back.

(((Kit posting as MickeyX)))

Made it to school ok, but forgot my iPod (essential for doing homwork etc in the 4 hrs I have between classes) so I had MickeyX ride out and meet me. 

The ride here was fine, I explored a new route that's more direct and involves less neighborhood/small road BS.  Delilah handled fine, with my books in one hard bag and schoolbag in the other.  Still no evidence of camchain noise, but she idled a little funny this morning.  Might need to doublecheck the tightness of my plugs, but otherwise, it's sorta neat how quiet it is.  Without the cam chain noise, I can just listen to it run, the soft ticking of the valves (not clattery, just hearing them) and all the other moving stuff.  Very neat. 

Little bit of leaking from the oil filter bolt, though we torqued it to 7 pounds.  It's not enough to worry me, just a drop that escaped after having the engine shut down for a few hours. 

Lots of fun. :D Can't wait to go home.  ::) 8)

Hello Margaret, it's me again...  ;D

I think Delilah will start up just fine. She has about 6hrs to cool down between rides and we only have a starting issue when the bike is still hot.  I'd like to be able to switch out parts with the other bike but I know the charging system is gone. In the end, we will probably change the rotor/stator with a new(er) set. Everything else checks out perfectly but those just don't give me total confidence. It does fine for around here and since $$ doesn't grow on trees or out of my azz, it will wait until after I get a set of bags and windshield for my bike. It gets a little hard on my back (and front) having to pile everything in a backpack all the time and then having the wind yank me around to boot. If I could get some overtime, it'd be no big deal. Alas, I am only 1/2 way up the totem pole at work and all of the senior guys are grabbing the vacation overtime. I have a sign-on bonus coming in a month, the last one of the series, and will try to take care of Kit's bike the rest of the way then and get carb/engine gasket sets and spark plug wires/boots for Sampson. It never ends, does it?  ::) ;D

Glad to hear that the cam chain adjustment seems to be sorted.  I agree that when these bikes are dialed in and you're listening to the sounds of all the mechanical components, it's a thing of beauty, like an orchestra.  Many disparate parts working together in a precision concert of motion and action.  It's part of the character of these bikes that I find appealing.

Re: the oil filter housing, did you oil up the o-rings before reinstalling?  Coat them lightly with some engine oil before re-assembly, this keeps the o-rings from twisting or kinking as you torque things down, just like when installing an automotive spin-on filter.

And no Mickey it never ends, but it does get easier once you've got your restoration work caught up to the decay rate of the bike.  Remember you're making up for years of neglect by Previous Owner(s) <shakes fist>.  Once you're past the restoratio phase and into the maintenance phase, I'm sure the bike will give you years of reliable service.  That's another thing I love about these bikes, treat them right and they're like tanks.  Heck look at all the 750's running around with JB weld holding the cases together, and the owners often don't even realize the damage is there until they clean the bike off lol.  Lesser bikes would have given up the ghost years ago!

gotta sort out an interesting amount of oil leaking from my valve adjustment covers.  :o  At least I know my top end is getting oil. ::)

Missing some o-rings?  It's also fairly easy to crack the tappet covers if you over-tighten.  Check for cracks where the threaded portion meets the top of the cap.

A couple of those bolt holes were stripped (in the valve/cam cover, not the valve adjustment covers) so I was a bit ginger about tightening them down.

I bought some yamabond to put on the aluminum mating surfaces, just a tiny, thin so-you-could-see-through-it amount to help the gaskets seal, and I'm going to revisit those stripped bolt holes, though I'm not sure what I could really do about them without taking the whole valve cover off... which I suppose is a possibility, but dammit I've just gotten the bike rideable and smooth, and every time I open the bike up, there's a 25% chance one of those little 8mm bolts is going to strip. :P

Leave them Kit, ride and let it leak a bit, after a while the little bits of crud left floating in your nice new oil will work their way to the edges of the motor and possibly seal up some of the minor leaks.
Oh yeah they are there unless you split the cases and did a total clean-out. ;)
I got told once that if my SOHC4 didn't leak from the head somewhere it probably wasn't a Honda  ;D so live with the leaks a wee bit and see what seals its self up.

marti- could easily get to them with a drill, but since they're in the head cover, (the one that goes over the valves 'n has the tappets in it) I'd go crazy worrying about all the little aluminum filings that could get in. 

Hush- this is bad enough that it looked wet down the front of my bike and cars all around me were looking at me because I was smoking that badly. :o  I can handle a dribble, and have a few here and there, but this is more than that.

MLinder: where can I get a socket like that? I've got a Craftsman set and so far it's just been rounding the filter bolt head.

I want to avoid grinding if I can, or any other drastic measures. A friend suggested heating the bolt up with a heat gun, but not so sure near oil/gas.

As an aside: those fishing/biking women - Kit and MickeyX. Wow.

Best,
SMQ

for us, there was no real alternative to grinding.  Even after grinding the whole washer-like part of the oil bolt off, it was still stuck fast to the housing.  :-\

We got the bitey sockets from Sears but they just chewed the end of the filter bolt head up.  I mean CHEWED.  with TEETH.

I HAD been, but now that I have new oil/ filter, I have oil pressure and leaks.

Gonna try to seal those up tomorrow, maybe helicoil, too, if I have to.

Yup, we are having all kinds of fun with this bike, Hush.  :D

We'll be in the garage tomorrow pulling the covers off and seeing if we need to helicoil or if we can just seal it with Yamabond. Fun, fun, fun. Off to check Harbor Freight for prices on helicoils just in case.  ::)

And just think... we bought a 2nd bike just like it to play with.  :o ;D

oh. Someone ELSE mentioned the pickup coils in reference to the CB650s not starting when hot, goddammit! I'm not the only one!

They took their right engine cover (the pickup coil cover) off and the bike started better when hot. Then he replaced the pickup coils entirely and the bike started fine  again, hot or cold. ??? Total weirdness.  Does that make any sense, because if it does, I'm willing to give it a shot.  I'd like to be able to ride into a gas station, fill up, start up and ride off again in the same 5-10 minute space.
