Hi Will, no - I never did determine the cause. I bought the bike like that, and factored the cost of getting it welded into the price I was willing to pay. In the end I took it down to a guy I know in Brackley, and he welded it up with no problems. The weld wasn't flush; it was built up on both sides but he did a neat job and it's been fine for the past year. The bike is currently in Stafford and I'm in Sheffield, but I'll get some photos taken and post them up.Hi Graham,
I've got a Falco with the exact same split in the casting, did you determine the cause? Mine gradually split and is now completely separated. Did you have to do any re-bending of the frame to get the two parts to meet again? Mine has about a 3mm gap.
Any advice would be much appreciated!
Cheers,
Will
