Flawed Logic, its going to be a money pit, and for what it will cost you you'd have been better off buying a decent Bantam on the road.
You will get some spares from France, but the postage will vastly increase the cost.
Tin ware will be almost impossible to find, as will any mechanical info in English.
I have given out french spares sources on here before.
I have previously passed comment on here, and upset those who are thin skinned, on the folly of buying old french two strokes that don't run or are incomplete.
If I were you I would subscribe to La Vie de la Moto, which is the french version of Old Bike Mart and learn at least some basic mechanical french terms. The value of LVM is that it will have lists of 'Bourse' events [autojumbles] and you have an excuse for a trip over. But very few bourse are anything like ours, mostly less than a dozen stalls of tat. The biggest is at Strasbourg.
As for the bunch of money grubbing hypocrites in the VMCC, they always hated non british bikes.
Unless of course one of the favoured few was selling one.
Does yours run?
