Alright guys,

Does anyone know if the crank cases from a 93 gas gas 330 will be the same/interchangable with those from a 91 gas gas 250?? Im guessing that if its the same engine then the difference in engine sizes will just come from a difference in the bore meaning the same crank cases, but im only guessing. Anyone know anymore???

`93 should have gone to a case induction and the previous years were not.

Hi sheffieldtrials,

The 93 330 has barrel induction and hydraulic clutch slave.

The 91 250 (Delta) has the same RHS case as the 93 330, the LHS is the same except for not having the hydraulic clutch slave.

I would say that the 93 330 cases would be interchangeable if you include for a clutch hydraulic slave.
