Thanks for that Dave.

But back to my front brake.  Now, I’ve ordered a master cylinder rebuild kit.  Scheduled to arrive next Thursday.  It’s really just a shot in the dark.  There’s probably nothing wrong with the old one.  I think I’m just rubbish at brakes.

The SOHC engines are generally noisy I find, at least with mine. A carb sync does help. There is a damper for the primary chains but nothing in the clutch basket like the DOHC's.
If you pull the pan you can measure the deflection of the chains to see if they are still in spec. This is described in the workshop manual. Cliff.

Whoa.  I’m not planning on getting into major mechanical stuff just yet, unless it’s absolutely necessary.  From the little I’ve read, it’s not seriously as yet.  Dang, I don’t even have a manual.  ☹️

Man, what a storm last night.  We’ve been in our house over 20 years.  Never had the power out as long, 5 hours.

Today, I opened up the doors and did a vacuum sync.  My bench sync was so close, it really wasn’t worth the effort.  I’ve never really been good at setting air mixture screws.  But once again the bench setting seemed pretty good.  One turn out from seated.  

Now, if only I could get the front brake sorted.  ☹️☹️

Really looking forward to getting her out and put her through her paces.

Up to +- $4522.

The Delkevic exhaust sounds really good in the shop, but is fairly loud.

It adds up fast doesn't it?  Chain, sprockets, tires, brake parts, battery, maybe a new seat....

[Galactica]

Ha, I didn’t even get new chain & sprockets!

AAAGGHH!!!  I’m rubbish at brakes. 

So I got the brake light pressure switch and master cylinder kit today.  Installed them.  Put some fluid in the reservoir.  Pumped the lever a few times.  Some bubbles came up.  Then nothing….  No fluid at all is going into the system.  WTF!?

   Often it take an overnight sit to allow the air to contain in one spot for easier displacement. often tapping the master cylinder and rolling it around to release air out of corners,,,,,yes its frustrating.

I've been known to crack the bleeder, fill the reservoir and walk away for a time.

I finally bought a mityvac.  They work.

+1 on the Mityvac.

Yup.  Did that overnight.  No joy.
