1959 BSA a10 super rocket

[hedgehorn]

New to the board here.I recently aquired a 1959 BSA A10 it was origianaly owned by my wifes father
that was killed on it in December of 1963 and has been in storage since. The
tank was drained when it was parked. I am currently in the process of
restoring the bike and have been doing some reading about them. I have read
on the internet that the bikes have a sludgetrap in the crankshaft. The bike
only has 6500 miles on it I was going to reseal the engine and go from
there. Do you think that it should be dissasembled to replace the sludgetrap
or would I be ok to reseal the engine and run it? Any info would be greatly appreciated. Thanks,

Todd,
I don't think that 6500 miles use would be enough to have filled the sludge trap, although personally I think I would be inclined to strip the engine/gearbox as it has been standing for so long,  then at least you would know that everything is as it should be.
If you find little or nothing wrong with it then that is a bonus!
But the final decision is really up to you!

Your bike would have been run on straight monograde oil but it is more convenient to use multigrade these days as it is easier to find when miles from home and the tank is low. Before using multigrade it is best to strip the engine and give everything a good clean, including the sludge trap and the oil tank. This will prevent the detergent additives in the multigrade oil from washing off any old sludge deposits and circulating them round your engine. As LAB says, you also need to check it internally for corrosion given that it has stood for so long.
