Did some small bits and some sacrilege xD
Created and 3D printed some simple chain guards from PETG. Didn't have any idea what the originals looked like; they fit, but not sure about the durability.
Replaced to top triple with an unmodified one; the previous one had the lock mount cut off since it would interfere with the old RS50 frame. The original Honda cylinder didn't fit, so I connected the R1 cylinder to the Honda connector, so my NSR is now started by a Yamaha key. xD The steering lock is semi-functional since it is offset, but now you just can't turn right with it on.
Also, I guess the thread name doesn't make sense anymore since I bought an MC16 subframe. I could have bought the MC18 88 subframe, new FRP tail fairing, and LED lights that are drop-in replacements for the OEM dual lights, but the prices that people want for the undertray piece are outrageous. This one was listed on upgarage for a while for around 1000 yen, but it cost another 6000 to ship it to me. Seems to be in very good shape, the tank mount has a slight bend, and there are spots of rust, but the undertray piece is pristine.
