Static timed, then 35 mile round trip to boy scout training. Meeting got out later than expected so I had a night ride ahead. Bike ran well (besides the ole head leakin) amd was remminded why I love riding these bikes....

On a ride like that all semses are amplified....a little fear, a lot of excitement, and everything is intese. Every vibration and sound from the bike register within my mind and with every second I know she'll get my home. The feeling from cold (yes its already cold at night here) to hot as the engine warms. The bike turning darkness to light to lead me into town from my rural origin....

It was a great night!

You're training to be a boy scout? What's the cut off age for boy scouts in your parts? ;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?"

I'm sure I floated the valves quite a few times. The tach needle flew past redline a lot.
Oh good, so my observation record of only losing a tappet nut by over revving stays intact.
Good to know.  I'll try and keep from over revving from now on  ;) in the mean time....new valve cover gasket will be here tomorrow so the motors coming out tonight to find that damn nut.  And maybe some cleaning while it's out.
I'm going to cry if it somehow made its way to the lower end  :'(

Yesterday after noon I rode mine from Buckhorn MO (about 150 mil west of St. Louis) to Marshfield MO (22 miles east of Springfield) to setup electrical, water & sewer at the house we are renting.  The best part was that I made the entire trip with out once touching I-44.  I took Route 66 all the way there and back, a 130 mile round trip. :)

The only path to the bottom end from the cam area is down the chain tunnel. That will put it in or near the sump area which is reachable by removing the pan. May have to remove the oil pump too, but you want to do that anyway. Simple jobs.  Clean the screen and replace the ORings.

Disassembling the bottom end is not an absolute.

Once the nut is off the adjuster there is no more jostling around. The nut will stay where it lay. I bet its near the tappet involved, waiting to be picked up.

Good news MCRider  :) Thanks for inspiring some confidence.  That's what I was hoping but I did ride about 100mi home with it like that  :-[  Made me sick to my stomach to listen to the ticking for two hours... I thought I effed up a valve.  Glad the tappet didn't punch through the inspection cover though!!

p.s. think it's worth checking the oil pan before pulling the motor??  ..I imagine it stayed up top....

I think so. The engine will still be upright in the frame. If you try to take the pan off once the engine is out, you usually turn it upside down and that could be bad if the nut is down there.

Good point.  Well I have a stand for it, so I'll put it on there to drop the pan if it's not up top.  Thanks again!

I went out to the cluttered 1 car garage filled with couches, washer, drier, engines and all manner of other mechanical and household stuff.  Stared at her half disassembled with no room to work on it and cursed my bank for taking so long to close on the new house with the 3 car garage.

The pic is before the garage got cluttered  :o  Currently she is on 2 wheels again with new (to me) forks, but basically just the engine in the frame.

I found an airbox filter in my stash of 750 parts, glued it into the K6 box, double checked the tune up, put on the rear rack & backrest, and made her ready for my friend & his wife to ride on a three day trip to western NC starting Friday.

The wet suit is safe for now:)

(last night) Had a "WTF?" moment, removing carburetor bank from a project.  Number 1 was marked 050A, and Numbers 2-4 were marked 657A.  All had #120 mains - didn't check the other jet numbers.  Anyone familiar with an "050A" carburetor and compatibility with "657A"?
Rubber intake boots were a little loose, which explains the slow recovery back to idle.
Anybody out there have experience with missing rubber grommets on the round-top carbs where the slide rod goes through?  How important is this part and what clever fixes have you come up with for replacements?  This has to have been discussed somewhere in this vast resource of knowledge.... :)

I do not know the specs of a 050A carb but the specs for the 657A are listed at http://www.hondachopper.com/garage/carb_specs/carb_specs.html 

The 657A stock main jet is 110.  But then, I have no idea if yours were rejetted because of engine mods.
I don't have a motorcycle, sold it ('85 Yamaha Venture Royale).  Haven't had a CB750 for over 40 years.

Spent last night on the interweb searching for "boring and honing services in Melbourne".

Problem is - I am a little ham fisted on the keyboard, so I typed into Google

"horing and boning services in Melbourne"

... I was on there for hours.

Can I have a motorcycle when I get old enough?
If you take care of it.
What do you have to do?
Lot’s of things. You’ve been watching me.
Will you show me all of them?
Sure.
Is it hard?
Not if you have the right attitudes. It’s having the right attitudes that’s hard.
