If leak is tolerable, I say keep riding

Thanks Goldarrow for your words of wisdom, went for a 120 mile today and no oil leak.
The gasket swelled up, hopefully doesn't start up with the short trips back and forth to work.
It was 78deg today, spring is here.

I have the same minor leak on my '76 550.  Not pulling it apart for that.

The oil leak seems to have stopped, I really don't want to take the head off, hopefully it will make it through the summer and fall. Ill need a project for next winter.
CJMC show and swap meet in Auburn is coming up in a few months. They have an evening ride and I'll probably enter the show also, I have no intention on winning I just like to see all the bikes no matter what shape there in.

Runs perfect. Oil leak at head gasket as gone away. Need to get seat redone, foam sucks. Found at one time guy sell seat foam but haven't been able to find it.

Got a set of carbs off ebay.  Mine were very corroded where the main jet slides in, almost to the point of not sealing. The carbs from eBay were in excellent condition, even the slow jets weren't plugged. Rebuilt and ready to install, DAVE500 gave my a good tips Im going to try, soldered the air screws. This to make it a little more rich at idle, should start easier, its really cold blooded. Im also boring to 1st over, compression was low , water had gotten into the cylinder. Ive been running it, just never did anything about it.

My elderly in-laws are living with us for awhile , so started garage projects. 

Im installing Delkevic. headers, hopefully this set up will workgood

My jet setup.

needle 4th posistion

Just got this running, I restored it 5yrs ago but I never put in new pistons, just re-rung it. Only had 1243 orig mi, a little moisture had gotten onto the cylinders. Bike just wasn't running so good, I did realize how under powered it was until i got the bike running with new 1st over bore, I also fattened the fuel mixture, new coils and a brand new set of Delkevic headers. It has never ran as good as it is now.

Blast from the past!  I dont have that ^^^ CB500 anymore but I just bought another that I will be getting back on the road!

I'll need exhaust, what are your thoughts on the Delkavic?

BTW - I'm nominating you for BOTM....

[rtbmrgl]

well thanks Stev-o for nominating me, maybe third time is a charm. Always stiff competition.
Delkavic is top notch, fit perfect, sounds great and and nice craftsmanship. I need some pizzazz, the bike was sitting a lot while i rode my Norton, I had guilt.
I saw your post from 2014.
