93 & 94 cases are provision 8......
However,the crank needs to be machined to match the taper of the gearbox and the case holes need to be worked a little to accept the gearbox bolts.

Are these also the ones with 2 magnetic triggers on the fly wheel for use with the Ducati dual ignition?

========================
All 670's, 1992 to 1999 are Provision 8! Most 1995-99 Provision 8 Top Holes have been Doctored. Some have bottom Left Boss Milled Off. Both Fixable.
1992 670's had a PTO Crank Issue and are very Rare. The upgraded 1993 670 Fixed the PTO Crank issue.
A Stock 670 in a Sled is 115.7hp@7750rpm! There was a 670HO in 1998-99 Only about 15hp more than Standard 670.
Only the 1992 to 94 Cases can accept the Ducati Dual Pickup Ignition!
The 1995 to 1999 670 Cases have a Black Plate over the Mag.
670HO uses Flat Top Pistons with better Ported Cylinders and uses 12.5cr. The HO Head has Dual Temp Senders on the Side, Standard 670 has only (1).
Rotax Rick has come up with a way to put Dual Ignition on the 1995-99 Engines.
The B Gear Drive can't handle the 670's Hp, you have to use the C or E Gear Box which uses a Donunut or RK400 Clutch, which is Machined for the 670's Larger 33mm 1:7.5 Taper PTO!
