Hi All,
I am just back home in Ireland after spending the last 3 + weeks in the USA on the Cannonball event
I was there as mechanic and driver of the service van on behalf of two riders, one of whom rode the black Ariel
The second rider had a 23 HD model F (magneto ignition J) that I had mechanically rebuilt over the last year
Unfortunately the HD rider fell ill and was not able to complete many miles
The Ariel rider/ re builder wrote a very long and detailed blog of the rebuild on Britbike forum
http://www.britbike.com/forums/ubbthreads.php/forums/7/1/ariel-forumThe Ariel suffered a few (mostly simply repaired) problems but got to the finish in one piece
The main problem encountered was when the Ariel lost compression (exhaust tappet kept tightening up), The exhaust valve seat in the head was recessing and the guide wore badly
A Norton 16H guide "borrowed" from Team Norton luckily had the correct ID and OD but had a large shouldered section, I turned this down using Team Nortons mini lathe, also polished up the valve for reuse
Another team provided a Neway valve seat cutting kit and the seating got a severe cutting
It really needed a new seat, but needs must
Opinion was that as an oil ring was fitted to the new piston no lubrication was getting to the guide, even though 2 stroke oil was being added to the fuel
??
I'm not sure I go along with that theory !!
The Norton Team did really well and only one rider dropped some few points
I was delighted to see the 3 flat tank Triumphs did so well (models H, P and N)
The model H had been converted to chain drive using some massive sprockets and a tensioning gadget
The Brough SS100 suffered guide/seat wear the same as the Ariel, and a broken fork
The overall winner rode a HD single
