Hi Dean , nice pictures ,you sure thats a BSA ,I can't see any oil drips !! Seriously very nice looking bike and has you'll know already this forum is very friendly and the members very knowledgeable and helpful, ( Could you post any piccys of the 3 wheeler I've only ever seen them in drawings and via discription from my late Dad. )Just an aside and no way detracting from it , looking at your bike do you have suppresser caps fitted 'cause there have been quite a few posts saying don't fit 'em with a maggy ,not sure if that applies to BTH maggys but worth taking into account . sure someone more knowledgeable than me will comment ,very best of luck with the bike and look forward to seeing further piccys and posts BobH
