Especially the unrestored 8-valve Indian racer was scrutinized. Took a lot of pictures of frame and fork details..

Oil Pump
It seems I can not get hold of a period correct oil pump.
When bidding on eBay there is always someone that has more money.

I'll use a Jawa oil pump, if possible, until I find a suitable Pilgrim or a Best & Lloyd or...

Valves
Still have not found any valves. An option is to adapt valves from a newer/modern engine.
Using valves with cotters would mean I have to find suitable collars too.

Intake and exhaust nuts, prologue
Rusted as if they were welded to the cylinder, but at first I had wery low expectations regarding the Spark Plug and Valve Cap too.
Maybe this will solve it self after the cooling fins have been welded. Either by the heat from the welding or when the cylinder cracks when cooling after welding.
Intake
Tried with an adjustable spanner but did not dare, in fear of ruining the nut. After more soaking in citric acid it looks like the thread is left handed.
Anyway, the thead has been soaking in penetrating oil while I have been loking for a ring spanner with the appropriate dimension. Measured with a cheap vernier caliper it measures about 32.5mm. Have not been able to find such a spanner. The closest I have found is BSF 7/8 or BSW 3/4. That would be 1.300“ or 33.02mm which it could have been before all the corrosion started.
I think I'll try a 32mm ring spanner and with some luck that will fit. Buying a imperial size spanner is the last option. I might even grind / open up a metric open end spanner before that.
Exhaust
This one is a real challange. Maybe I'll try to cut the nut to get it off. Both because the required spanner and the condition it is in.
Think I might have to make a new nut anyway... maybe from broze or brass?

Valve Cap
Made out of aluminium, but just got one out of two.
I'll try to manufacture a pair in my lathe even if the hex head is not that easy to make in a lathe (have not got any milling machine).
Wonder what thread it is? The pitch is 1,5mm and that would correspond to 17TPI and that is no standard thread as far as I know. Will make the hex head 38mm which is 1 1/2"
