Thanks,
I might try the cold setting method with a 2x4 to spread the right side (now the spacing is 123mm), but I'm a bit worried about damaging the seat tube by levering on it, sv980 is stamped on the main tubes and the frame feels quite light. Even if this were successful I doubt it would help with the vertical misalignment, so was wondering if there was another way.
Rear wheels were pretty obviously out of line in reference to spacing and angle with the seat tube so I'm just hoping to eyeball things and give it another try. If it feels good then might be the time to take it to a shop to check the dropouts. I'd fee dishonest taking it in as is for some kind of estimate as I don't want to spend much money on it.
