setting up bars are ez you need a level and a tape measure. first thing is to set the bike on leavel ground and bike on a swing arm stand or something to to hold it streight up and down . Put the leavel on the rear brake rotor to make sure bike is leavel, now with bars installed put leavel on cross bar that holds the wheels on the bar and make them leavel. this is a starting piont for ride hight of abrs i put the front trie on a 2x4 piece of wood and have the bars just touching the ground. that is the other starting piont. now as track and tire traction change you can ajd bars as needed, if the bike starts the buck up and down the bars are unloading the back tire lower the bars a little bite, if the back tire spinns a lot rise the bar a little . remeber a high bar when the bike is launchs hard it will unload the tire and cause tire to spin but once it spins, the bike will be off the bar and get more traction and stop spinning tire and go back on the bar and unload the tire and lose traction causing the bike to buck. I always start will the bar as low as 2" and go from there . I hope this helps .
