1 K75 yokes on K100 8v Sun Jun 30, 2019 12:46 pm

Hi all,
I have fitted some Showa forks to my '89 K100RS and did eventually get the yokes to clamp the new, slightly smaller diameter forks but I don't really trust it as I had to tighten the bolts about 4 times before the forks stopped slipping upwards. I also have a notch in the steering head bearings so I figure why not replace the yokes with proper Showa ones at the same time? Problem is, some research has reminded me about my handlebars being rubber mounted and the 75s had that Fluidbloc thinger so maybe it's not that straightforward.. So, question time!
1) Can I fit K75 top and bottom yokes? Am I missing something obvious that would be a blocker? Will my button pad thing still fit?
2) Can I fit just a K75 lower yoke? If the bottom was clamping properly at least then I'd feel much happier, given the size of the bolts in the top yoke it's very secondary anyway. Are the threads the same on the stems? Are the stems even the same length??
3) How buzzy are the bars if solidly mounted on a 100? I do actually hate the queasy feeling of the rubber mounted bars but I'd also hate constant vibration white finger..
Sorry if all this has been covered time and again but a google search didn't bring up any help..
