I'm trying to make a 100cc. road toad motor. I have all the top end but don't have the cases. I'm wondering if the combat wombat 125-100superrat model 94-95 cases will work?
By part numbers the 100cc road toad base gasket is different from the 125 base gasket.
Any help?

None of those cases wil work to make a Toad engine , The cylinder will slip on to the cases but the cylinder spiggot is way smaller than the 125 and will leave a huge crancase pressure lowering gap. And the Early ace cases wone go at all , different cylinder stud spacing. The cylinder will work on the 98 Rat cases but still wonnt make a Toad with primary kick and oil pump. You would be better of locating a Toad engine.
