Well six hours after starting I have my new seat mounted. Removing the spring assembly was quite the challenge. All nuts were rusted solid. I was able to save six of the nine. The other three I had to cut off. I want to thank Jethro Smith for the perfect seat. Impeccable workmanship.
My new seat arrived! I did not want to use the original 106 year old leather seat as it is too fragile.
I want to thank Jethro Smith for outstanding work on both of these items. http://www.antiquemotosmith.com/
The intake valve and seat are unique. This is an atmospheric system requiring no external pushrod. The intake open on the downstroke of the piston. The valve is sucked open during this. This assembly is comprised of several parts. Here is the complete setup (on the right) and some extra parts.
Top motor mount pieces installed.
Rear breather pipe before and after install. This vents any excess oil out the rear of the engine into the frame. Excelsior advertisements in 1911 advertised the Excelsior as the “cleanest machine on the road that will not soil your trousers”.
The belt and lagging arrived from Page Belting (http://www.pagebelting.com/history.html). Excellent customer service and delivery speed.
Lagging installed on front pulley.
