Hi Vincent[attachment=0]
Yes, well spotted. It is another motor in the picture I have made from the Adrie original crankcase. I to do not want to take over your story so I may make a new thread sometime.
After I decided on the pully ratio I have made the g/box mainshaft and crank centers fixed. It has to be because of the starter gear. I to made an outrigger bearing but have since taken it off at this time. There is no problem fitting the belt on and off. You need the belt to just about turn through 90 deg when fitted and there will be no problem. Don't have it tight it will break, I know.
The original Ariel V twin which I wrote about in Cheval some time ago has covered about 3 1/2 K miles.
At this time the engine is on the bench but out of the second set of crank cases I have made a 1000cc engine. Although based on the Adrie modified crankases I have uses my own barrels and Norton M50 heads.
I have made many upgrades and will in time update the Ariel engine and mount this into mid 50's Ariel s/arm frame as I alwasy wanted to.
I have also made a Egli type frame to but the new engine in and it's made a very nice toy don't you think.
Cheers for now Tony
