tech/recognise this question.
hello, i picked up a 1997 918 blade rrx with unknown history, to me.
seems to have been well looked after. under the seat there is a small box with red cable leading under the tank. where one part plugs into the pickup, and the other side plugs into loom.
on the back of the box is big letters, S H with a line under them. nothing more.
on front of box is a row of dip switches and a single push button.
im guessing either its a old style type mapping and rev limiter box, as this is carbed bike, maybe the idea is the map the ignition accordingly to what ever up jetting work is done?
but from what i can see all the jumpers are set to zero, and i have no manual to know how or where to start resetting it.
will post pics later when i figure out how. thanks.
