Nice riding Ron. I'm off to the builders merchant to get some concrete blocks and with them in the panniers ill try to wheelie the M20. Not sure about trying a stoppie with girder forks though...
Lee you dont need concrete blocks in your panniers to do a wheelie i have done one on my M20 i gave it a handful in first and changes into second but gave it the revs before i dropped the clutch i am nearly certain the front wheel came off about an inch for about a second frightened me to death
