So far all I have done to it is lower it. What mods have helped you get the best results and most importantly what helps you keep that front end down?
I'm gonna assume your bike is stock wheelbase,so you'll want it as low as possible but not too low;if the swingarm is less than parallel to the ground and is angled slightly downward you're too low. Make sure the front is lowered evenly with the rear.
Set your the compression on the rear shock for maximum squat,and the rebound set to rise slowly on launch.
On a SWB bike,the 330' is more important than the 60'. Concentrate on launching smooth,and dropping the 330'. You ET will drop considerably.
A 600/750 can be launched pretty hard without wheelying as there isn't too much torque to fight.
Run as close to 30-34 psi in your rear tire as you can without traction issues.
Pick a gearing combo that will allow you to go through the traps at the top of a gear. That'll take some time to get the right combo.
Always use Suzuki OEM clutch plates.
I'm leaving out quite a bit,but that'll get ya started
