Hi. im guessing im not the first to ask about this, but couldnt find much info on jack up bars (dog bones) in the search. A was wondering if it would be worth me getting any jack up dog bones for my B6K3, do they any good, or arnt they worth the hassle. I've seen them on ebay at 3 different sizes 6mm, 35mm and 50mm but not such which would be the best. Any ideas?

50mm ones on ebay

Well, the site that's selling them tells you what they'll do... though they might not be coming true with the statement "These kits do not affect high speed stability." - especially with a 50mm (~2 inch) tail lift. They do increase handling sharpness and this invaribly come at the cost of being more nervous in a stright line, especially at elevated speeds.

A 50mm change will render your centerstand useless, if you care. 35mm is a safer way to go and should still permit the centerstand to work (I know it does on a 2G B12 anyway), though the ground better be flat. There is a thread in the FAQ on how to make your own dogbones.

I've just bought some 55mm dogbones but not fiited them yet (for a 1g B6). What speeds are we talking about when you notice instability and how bad is it? I presume it gets progressively worse as speed increases?

I had a 35mm change with dogbones and now run ~32mm change with stock bones and a Busa shock. I've never noticed "instability" but the bike does respond quicker to inputs. I would bet any problems could be magnified by this change in geometery - like the headshake from a cupped tire.
