The bolts Garauld has recommended are the standard Yamaha size. Just remove the Motech sliders and fit the new bolts without the sliders or get new bolts from Motech. Support the engine from below when removing the bolts.

Push a pencil or dowel or something thin down into the hole and measure from the hole bottom to the face where the bolt head touches. Procure the next shorter length bolt(s).

No sweat, mate. Post pix here (or send pix to me in a PM) of the bolts in question, and I'll see what I can do to help.
Cellphone pix will do just fine.
Relax, man; nobody here ever started out as an expert.

P.S. Life is too short, and health is too valuable, to ride on cheap parade-duty tires.

There are several engine mounting bolts, item 13 are the biggest ones. Engine won't fall down if you take them out. Yes they are fine thread 12mm but I'm not sure of the length. I believe that boss is open at the interior side and a long bolt won't hurt/should go right through.
Use anti-seize as those fine threads like to seize, reduce torque to under 30 ft. lbs.
