Sounds like you had some really good results on a limited budget, I haven't got 2 pence to rub together but trying to put an NSR back on the grid and do it justice, I've searched the forum loads to find people still racing them but it seems to dry up after 08 or so in the uk at least.
I'm hoping mine can stay reliable but I'm the same can't really afford blowing the bike up every other weekend. I bet buying the F-3 kit back in 87 would have cost as much as another bike! Same today I suppose except you can't find the parts :p doubt even the most highly strung TZR could cope with 68ps.
Why did the other riders kick up a fuss at 3 sisters? Really glad to hear the chassis and breaks where/are so good, if I can get mine handling anywhere near as good as my NC30 I think the bike will be good enough for podiums in the sub64 hp class I currently race in only problem is the rider! :p only trouble at the moment is tyres, looking likely that I'll have to source a couple of 17' rears and at least 2 3.0/17 fronts, going to bump the weight up which is a shame, and I quite like the 3 spoke wheels.
I will post up plenty of photos and info on how I get on, unsure if it will be 2016 or 2017 that I do have it ready, hopefully sooner rather than later!
