New here, looking to build my SC28

If you want some ground up stuff (alot of banter inbetween though) my WBRW threads were based on the same color scheme you've got, quite a bit of info on swingarm swaps and wheel sizes as well as all sorts of "what fits and what doesn't" in general. Again, lotta pages of just discussion, so, make sure you've got some time if you are going to page through that mess... not sure how many pictures even work on there too.

Drilling the triples isn't that hard, I am struggling to remember if there was ever a write up done on that? I don't think there ever was... none the less, the 900 triples do not give a single shit about being drilled for dirty bars, I've done enough and abused the ever loving shit out of them enough, including tip over's into the bars, to know the triple is the last thing that will go if you are worried about strength among the parts you steer the bike with. I thought I had struck gold on a running, but naked and crashed '93 900RR back in 2011 for 1k, but, I think you got the better deal for a complete one that just needs a little work for $500. Awesome score. Also, if you want more relaxed geometry, the 1991 Honda XR250L/R rear suspension linkage "dog bone" link is a direct replacement but 2.5mm longer and relaxes the rear of the bike enough that it doesn't want to high side, as much. The Bandit 1200 1st gen front wheel is also easy to fit with the speedometer drive from the Bandit in order to gain a cheaper alternative to F3 front wheels and still get a modern 17 inch tire that will help immensely with both tire selection, and overall how nice the bike is to ride. Sure, stock is pretty wicked, but, with the XR link and the 17" front with dirtbike bars (I prefer Carmichael bend mid rise Pro Taper's myself at this age) the 900RR becomes a formidable weapon on the back roads of Wisconsin.
