KIPS is this thing working
I just re-did my 90 E2 model top end and had to work on the KIPS system.
There are 2 things you need to check,... get out your factory service manual (you do have one... right?)
Take off the right side kips cover, the arm that controls the kips valves comes from the crank area, peel that rubber bootie back to reveal an actuating arm. That screw you see is "reversed" threaded. Grab (support) the arm that goes in the clutch area with a pair of pliers to prevent it from turning, loosen that screw (remember it's reversed threaded)
ok.. push/pull that arm in and out of the cyl... is it moving free? look through the exhaust port, are they opening and closing? ??
If it is real stiff or stuck,.. you must dis-assemble, mine had bad teeth on the left exhaust valve. $36 part
yes?.. ok put it back together but leave the right kips cover off, that arm should open up about 6000 rpm i think.
was I clear?
