I recently purchased a new kart - it's shall we say a project... unknown make/ model, has a KT100 built by Stencil Racing which is going to need an overhaulin', brakes frozen, crappy homemade master cylinder mount, after searching the forum here I found how they are supposed to mount, and will be purchasing complete new brake system. first thing I did when I got it home was a complete disassembly, then grit blasted the frame to see what I got into. On the right side just in front of the rear axel bearing hanger I found a stamped # S283 which hopefuly will help ID the kart. The steering column has some rust holes, so I plan on replacing that as well as the rear bumper, which leads to another question, if you look at the photo of the bumper mount there is some epoxy, which I will clean off, but what holds that stud in place - I'm sure the frame isn't threaded, so...??? without destroying the tubing I want to remove the stud, fix any metal issues and replace, but not sure whats going on there. I've got my work cut out form me, but can't wait
