it all depends.. gear reduction means that u dont need to have like a 1:6 reduction.. it probably needs to be kept on, if you dont want it you should change the shafts and get another oil pan. but the gear reduction reduces MPH but gives alot more torque... i would keep it. gear reduction is usually more expensive than regular engines, and since its an 8hp its probably more xpensive than a non-gearreduction engine. if the "gear case" comes off the shaft probably has to be changed to another type... first keep the gear reduction on there and make sure it runs, take off the sprocket and put a clutch on, then see if it wil mount on the minibike frame
