Ok, drained all my coolant (while getting real shelby's new clutch basket installed), on 02 DL1000. I'm getting ready to put everything back together, and was reading the procedure for refilling the coolant. Says to pour slow, drain air out of bolt on housing, top off, and then run without the cap on. Is this correct (running without the cap on)? I ask because I did this once on a Honda ST, and as soon as I started it..coolant went flying EVERYWHERE! My garage ceiling walls, etc, were covered in coolant...I really don't want to go through this again!
