Quick question, and sorry if it's been asked before, I have a set of K4 forks and brakes to go into my 85 7/11 slabby my question is do I need to swap stems or can it be done with just a bearing swap. Don't have the K4 yokes yet so can't measure anything up.

Hi, in regards your problem I have an 85 slabby fitted with an 1100m engine and I run 40mms with an original airbox. I did need to grind down the inside of the frame slight, not a significant amount and certainly not enough to cause problems after that I had to cut two slots in the top of the airbox turned what I cut out upside down and plastic welded them back into place. It's still a very tight fit but is doable. Am going back to the garage later so if I can get a half decent pic will post up for you.

Would definately be interested in a pair but no money till nearer christmas (an unusual statement but true) so if you can wait yeh I'll have some
