Hello I have just bought a 247 C chassis/engine number 21M26447 for restoration. Its a late one I think and has the air forks which I understand were fitted from 21M25137?  Any tech specs or literature specific to this model would be great as I want the restoration to be as accurate as possible. 

Thanks Dave

I have a handbook for the 247c and will pm you re sending a copy of the vital data. Meanwhile  you should move the kickstart lever on its splines to the 1 o'clock position. If it's too far forward as in the photo it will damage the side casing.

Dave there is a Facebook site dedicated to the 247, lots of 247C owners on there😎

Great bikes, I love mine, super smoooooth engine and physically a small chassis, all really helps on the modern day sections. 

The 'C' is for competition, they were designed to be lighter than other '247' class bikes.

The odd cubic capacity was something to do with French tax breaks as France was a large market for Montesa back then. 

You'll probably know by now that most simply put a '250' jug 'n slug on it as the 237cc pistons/rings are made of unobtanium.
