That's it , no more poppings from the complex restrictive crossover pipe original bean can system. I'm glad it's gone , happy with the new custom MK111 downtubes built to clear the primary side and mated to the reverse cone peashooters using 2 barrel roller type pipe to muffler clamps. The Norton sounds like a Norton should now. Test ride had no poppings on fully closed throttle over run and I'm confident with it enough to go on a 2 day 300 km. fishing trip tomorrow. Plugs look good with a light gray colour , bike pulls strongly. This is a RH 10 head , .40 over 850 pistons rebore using 2 32mm Amals with tapered to 30 mm. intake ports , 3 1/2 slides (coated type for premiers) , aluminum needles , stay up floats , extended idle screws and throttle stop screws with new O-rings ( lightly smeared with silicone grease) ,extended ticklers , needle at highest needle position ( I think , not about to pull tops to look ) . no enrichener choke system , plugs in tops to seal that up , teflon linered cables that do not see oil , stock plastic airbox with new filter and hoses.
Wish me luck fishing and I'll pull the plugs when I return for a colour inspection.

Returned home after 22 days on the road. 10 days in Manitoulin Island Northern Ontario. MK 111 ran great the whole 1600 km. Trip. No mechanical problems at all. Other bikers gave us chain lube . Great weather. Camping and motels and Chichimaun ferry home via Bruce peninsula.

That is about a thousand miles, how dark was your oil when you changed it?

Quite dark , blackish. The bike used not much oil at all during the trip , perhaps half a cup or so. Did not add any and came back with the dipstick level just above low. I left on the halfway mark. The new oil is Castrol 20W50 Motorcycle using a genuine Norton Filter.

Was curious because mine is likewise and the weather mild. It goes in quite light in colour but comes out
pretty dark. Thinking I will have a go at another type of oil just to see how it goes.
