Velocette L.E. 200

Hey gang, I've been looking for a quirky brit bike for a good while now and
Just picked up a velocette L.E mk2, its a hand built motorcycle from a british company, here's a few pix for ya...
Mine is in the same kinda condition as the one in the pix although the paint isnt quite soo bad.

Just wondered if any of the brits on here or any other folks knew anything about tuning these a lil.
I'm not lookin to break any land speed records, i just think the standard 8hp motor could do with a lil tweaking...I dont want to stick another motor in it, altho i had thought about the CB200e that i have laying around, but its chain drice and the LE is shaft driven...
any thoughts??? :)
