Hello Adventure riders, My name is Matt, Here is a little info on me: I'm a 28 y/o MBA candidate at the University of North Texas in Denton, Texas. I recently entered my 1976 BMW R75/6 in the 2019 NORRA 1000 vintage class. I've been published in the June 2016 issue of Motorcycle Classics for my '77 Ducati 900SS, featured on a few Instagram post for my old BMW R90 and R80. I've ridden long distance on/offroad trips in America and Peru. I fairly competent in my mechanical ability regarding airheads, but have never done anything like this before. Currently the R75 is torn down, engine has a new rear main seal, bead blasted, freshened rings and is awaiting new valve seats. Its running the stock bore and stroke for simplicity sake. The frame was intended to be a street scrambler, but I decided to get crazy and enter this race. My main questions are, and I've seen them mentioned on this site via random searches, what is the best way to extend the swing arm to allow me to run 17" rear shocks and stock rear wheel. I'm basing my thoughts off the old HPN bikes. Utilizing a used KTM 690/950/990 front end with 21" wheel. Best places to gusset the frame and neck tube? Best way to keep silt and dust out of the engine and breathing tubes? Should I just keep it fairly stock and run it as far as it goes? (bottom pic) I've just started this build and am quite poor, currently moving, and jumping over to Europe for a month (why I'm so poor, irony) so it will be a slow build. But if anyone has tips or advice from failed or successful modifications, please let me know.
