Stayed in the garage all day today working on the 550.  New plugs, changed the oil/filter, and tappet adjustment.  I also noticed yesterday on a long ride that the front brake was dragging a bit.  I've never had the caliper apart on this bike, so I disassembled, cleaned, lubed, and bled.....so much better now.  I didn't realize how much it was actually dragging.  This may account for the somewhat poor fuel econ...we'll see I suppose.

Also, I recently rebuilt my master cylinder due to it leaking around the piston.  Well, it's leaking again.  All the guts are new, yet it leaks between the body of the MC and the handle.  Could it be a crack in the casting or something?

I'm about ready to toss it and look for a modern MC.  Any recommendations of which one to get?

Tracked down a small oil leak hopefully, one of my oil pan bolts was missing. Hunted for my carb vent nipple on my 77's PD41a's, turns out it doesnt have one after all. Checked the valves for good measure while I had the tank off, pulled apart my spare set of PD's while I was out in the garage. Oh and rode the crap out of it to and from work today, so far my master link is staying put for a change. :)

There is a carb float bowl vent.
Sorry lucky, on the 77 Pd41a's there is no vent nipple. I posted pics of them in the earlier thread where we were discussing it. 78 pd's have them 77's do not.

David Siver Spares sells a really nice aftermarket 550 MC mate, I bought one for a CB750K2 a couple of years ago, and it worked well. It's not an exact replica, but doesn't look out of place, and works just as good as the original. For 45 bucks, it's not much more money than a rebuild kit, an it doesn't leak! Cheers, Terry. ;D

I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Thanks for the tip.  That's probably the way I'll go.  Good price.

No worries mate, and if you're not worried about originality, a late model MC from a big Jap bike will actually be a big improvement, even with just the one disc.

I use a Suzuki 1200 Bandit MC on the front of my K1 (albeit with dual discs) and it pulls up real hard, and I had a GSXR1100 MC on it before that and it worked great too, but I didn't like the remote reservoir. They go for between 50 and 100 bucks on EBay, so aren't too expensive. Cheers, Terry. ;D

Greggo - that looks like bike heaven!

And I will be walking in the door of that particular heaven in three weeks time when I visit San Franciso, already emailed Charly and got him sorting out a few parts for me.

Shortly after midnight, in a daze from too much polishing,  I tried to adjust static timing with the kill switch set to off <facepalm>.  This morning I realized my mistake.  Got the points pretty accurately set and got the motor purring real nice now. 

Also reinstalled my carbs with freshly set float height and new OEM float valves. Seems to have cured my carbs terminal gas spewing problem.

Well, today was not a good day. I worked out a deal on a GL front end complete with wheel for 70 bucks. Guy contacted me after agreeing about 15 minutes later saying sorry I had over 50 calls for the bike. Front end is now gone... Nothing followed.

Started to bleed the brake as the new pads are rubbing my newly acquired lighted drilled rotor. Also raised the rear with old new shocks.  I like this look much better. Tomorrow she should be road ready. .

Took her out around town for a ride. Died downtown. Started button didn't work and had that dead battery groan when pushed. Kick started and idled fine though. Rode home and battery voltage was 11.27- pretty dead. I was idling a lot in traffic, and I hadn't ridden her in a few days, so I'm wondering if it's just a discharged battery, a bad battery, or a problem with the charging system. Have to figure it out Monday as I work all weekend.

Otherwise a great ride :)

Get the charging checked out or a new battery or the next may be a bad ride.You have to have up most confidence in your ride,especially if you may be out late at night doing naughty things,not that you would be.

Accolay,

Your problem could be any or all you mentioned. Our charging systems are not the most reliable. I recently took my "charged" battery to Advanced Auto to trade it in for a new AGM battery (REAL NICE!). It was old but it was on the Battery Tender and showed good voltage but wouldn't turn over the engine. Voltage would drop to 7.something when I turned the ignition on and the headlight came on. I asked if they could test it. I didn't think they could test such a low capacity battery but I was wrong. Something like 17 cca's! The AGM is rated at 220 cca. Take it for a load test at Advance if you have one close. If it's good then consider the charging system. If bad then get a new battery. Think my AGM was ~ $75 but it kicks ass. Other batteries can be had for ~ $40.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)
