As cool as that engine may be. It is hardly what I would consider as a minibike power-plant.
Now before someone gets the bright idea to suggest swapping this engine into a DB-30 frame, let's try to keep this thread realistic.
I now have a Sachs SA290 two-stroke single & a Tecumseh HM100 as the top dogs in the pile. Probably about half of the vintage/classic frames we use, are not tall enough between the top & bottom tubes to accept these 2 engines. Not to mention the excess width.
