Item 2)
The MC18 is the least restricted (see the model history and tuning links )of the 18 ,21 ,28 bunch so you should be looking at 58 - 60 HP after disconecting one wire and getting it on a dyno . Parts for the MC18 are ok to still get apart from the cranks but the roller bearings are avalible, but if you are looking at a low milage one you should be ok for years yet . You will have to wind up the suspension all the way to get it to handle if you are 200lbs though . Just go for it mate as they will not be around for ever .
