B&J racing did a lot of work with these bikes. Look them up!
Parts should mostly be available through RYP and here may be service info posted on the website.
Corrosion-x is a fav for prevention. not cheap, but a can goes a long way.
Better too much than too little, re treat and wipe surfaces if/when you can.
Bike looks great, keep it that way!
nothing abnormal about having to use the pressure to seat the bead as they go, but getting a rim band to seal mjay require a new one with integrated stem, well worth the cost!
