Thanks Ant for dropping me in it!! To explain my comments:
It wasn't a huge "off the clutch wheelie", the front just came up on the power
at a point on my test ride circuit where other bikes don't usually lift the front wheel... Which tends to suggest the engine is producing good, usable power!
I'm not in the habit of wheelying customers bikes.....I couldn't afford the repair bills when they go wrong.
I'm sure once you get used to it it'll make you grin even more, take it easy till you do though.....
