My '54 has a tank cut-out and dualseat leaving an unnecessary void between them which allows engine noise through to the point that when going on a run of several hours between stops I stuffed a rag in there to reduce the annoying engine clatter and carb chatter. It's cheaper than an overhaul ;) .


I have on a number of occasions temporarily used my hand in place of Spriddler's rag on my bike just to hear the difference. Amazingly quiet .....

Where did I put that old (very cheap) rag? :D

Comp tank with no rear cut out is rigid. The interesting to me one is the road tank without the cutout. cant get to them at the moment as they are in my lock up and i am imobile at the moment.

"imobile at the moment."

Well into the second bottle then, eh?

Hope to see you at Norfolk IJR.
