anyone got any tips for making your own 12 bar?

 

i use 1/4" thick 1.5" wide flat plate steel. i used 2 3/8" grade 8 bolts per side drilled into the subframe to hold it with lock nuts on it.

find your angle, or cut it close after you bolt on the side plates, then stand the bike up and see if it sits full 12 and all that jazz, then put your rear plate under it while it's on 12 and tack weld it. then bring the bike down and finish up the welds and bam, you are done.

anymore questions just ask man.

 

another way to get your angle so you don't have to keep lifting your bike up is to take a 4 foot level and find the molding nubs on the side of your tire( inbetween the rim and the tread) go from the ground through the nubs up to your rails that you have on your subframe and this should give you a close angle, something tho work with anyway.
Oh yeah, I don't bolt through the subframe I cut four pieces about 2 inches long and drill 2 holes in them and in the side rails. these pieces go on the inside of the sub frame to act like a clamp. Yes this is a lot more work but I've had really good luck this way. I do it that way so that I don't weaken the subframe by drilling through it. I'm NOT saying binders way is wrong, this is just another way. Hope this helps!!

 

ya, i used a 2x4 piece of board like you said to get an estimate angle before i put it on 12....then from there you can see you need to take more down or whatever or steepen your angle. took me only 2 cuts to get mine where i needed it then i was read to weld.

and i have yet had a problem with weakening the subframe....mine's a honda though, so you have to take about half the strength away to judge for the strength of a gixxer subframe...HAHA

 

wow thanks guys..alot more detail than i expected...awesome!!!
