hi there

I've got a zx-12R engine in my shed,
next to a bunch of sierra parts;
the MK kit is delivered next weekend, so it's time to get working on the enginemounts.
i want to make a cradle (round the cyl.head) to which vertical bars are welded.( down)
The cradle itself is bolted to the chassis.
What size tube-ing does everybody use?
rectangular 25x25? thichness /gauge?
( metric please ! )
is is necessary to weld a metal tube, in
which a metal+rubber bush? or is it possible to use a bolt through the square section?

I used 25x25 tube with round thick wall tubes welded in to solidly mount the motor. Don't bother with rubber mounting, they don't use it on the bikes so you don't need it.
Balance shafts in the motor do the business of sorting the vibes but even then they are only to enable bikers to be able to see thru the mirrors.
