i run one bike at about 3 " and the other at 2 , no real reason thats just the way it worked out ,
Dont like the idea of a strap, internally lowered forks work good for me
just keep it level, lower the rear the same as the front and if you push the forks through the tripples make sure you have more fender clearance than fork travel as the forks use a lot of there travel when you roll off the power away at high speed at the end of the run
