Pulled the sump off today. No debris and the oil pump pickup screen is spotless. Primary chain is nice and tight. Great!

It is! I ran the bike before I tore it down and it was very quiet. No chain noises at all. It did have some puck leaks, so this top end work is really to get it back to clean and dry. Replacing all the shaft seals too. All the covers came off today, will get them vapour blasted and then some polishing.

Are the old clutch plates worse by age, like hardening to bad gripping surface?

When oil pan is off, is the tensioner rubber wheel rubberish or has it transformed to bakelite?
If age or oil by use will do that.

Per, I have not opened the clutch up yet, and I will. Rubber tensioner looks and feels good.

OK, the oil and heat can be the bad for rubber then.

Maybe there are some oils that can make rubber to stay pliable longer and lube the engine with cam as needed?

And also oils that are bad for rubber tensioners.

When I picked this bike up, the oil tank, sump, and even the filter housing were empty (of oil; the filter, spring and washer were still there). Someone had written “no oil”” on the handlebars, with a felt pen. Very strange.

Despite that no rust inside?
If no rust, good dry bike saving storage

No. Everything had a nice film of oil. #4 piston and valves were a bit “dry”. I suspect that was the cyl. with both valves open (carbs and airbox missing). All good now.

Cleaned out the sump and screen. New gasket, buttoned up. We are off for 6 weeks on Sunday, so paint and polished side covers will happen when the weather gets a bit warmer!

We are off for 6 weeks on Sunday...

Mind if we ask where you are headed?  I just returned from a week in Aruba!

My wife’s Dragon Boat Team (Survivor’s Abreast, Peterborough, ON.) is headed for the International Festival in Cambridge, N.Z. I’m tagging along, so we are going to Australia for a few weeks, then New Zealand, south to north. Ending with a 5 days on the Island of Roratonga.

 I know the experts say all of the sandcast motors were painted but 5511 shows no evidence of ever having paint on it. It was pulled from the frame when the PO's son had the rocker cover and side covers chromed but he says he didn't remove anything else.
   I've dechromed the left side but the 9 bolt clutch cover and the valve cover are still chrome.
  The Dad was not pleased that his bike was taken apart without permission and I think that's when it went into the shed leading to the mere 7300 miles it had when I got it.

This one is definitely painted. Oil pan has no paint and the vent box cap (3 screws on top of the cam cover) is also painted the engine colour.

Thanks! Left both my torque wrenches with the local Snap On sales rep. I bought the big one (75-250 lbs/ft) to torque the flywheel centre bolt on a 1293cc Mini Cooper “S” I first raced in 1973! The small one came not long afterwards. Thought I’d have them recalibrated before the final pull for the head.

[RAFster122s]

John, good idea to have them recalibrated. The advantage of buying a expensive big brand tool is services like that...
Hope your wife's boat team does well and you enjoy vacationing in AU and NZ.

[Don R]

 I used my inch lbs and my ft lbs torque wrenches. The inch lb wrench stopped a little sooner but that was good with me.

[BenelliSEI]

We’ll be back home in a week and I can’t wait to be back in the shop! The International Dragon Boat Festival was great. +3000 Women in one spot and +50 heats! Australia and New Zealand were both places I could easily move to. Welcoming and stunningly beautiful everywhere. The population of NZ is less than Toronto!

A few days in the Cook Islands and then back to Ontario. Our race season starts in a few weeks too. Turning 70 in a bit and still “living the dream”. Cheers to good health!

[RAFster122s]

Ya have to worry about hitting sheep on the country roads in NZ and the Kangaroos in AU...
Much like the deer in Ontario countryside...if they are as thick there as in Ohio and Michigan...

Enjoy your last week in southern paradise John
 Hope the wife's team had fun and did respectable in their finish.

We’re back home. Picked up my torque wrenches today. The Snap On rep discovered the big one (+50 years old) was spot on and the smaller one was less then 5% high! I always wind them back to “0” and store them back in the hard case, when not in use. Seems to work.

All the engine covers that went out for VBlasting (they were rough) are ready for pick up. It will be interesting to see how they turned out. Hopefully I can get them in the next few days. First Test Day with race car is Sunday, first race weekend is in two more weeks. Fun times!

[BenelliSEI]

Picked up the engine covers today. Amazing results. They were really rough, corroded and flaky. I’ll take pictures tomorrow. I’ll have to strip down the carbs and get the bodies, float bowls, and tops done too. Really nice finish.

^ Good to hear, can't wait to see pictures.

Here they are. Polish or leave them alone?

[JamesH]

Polish gets my vote. Would look totally wrong as-is imho.
