Is it feasible too use the 212 Predator engine for Jr-1 (7-11 age/250lbs)? The intension is too run it 'as-purchased' from HF and de-activate the governor and 'seal' the motor. It would use the typical top-plate conversion kit and winnie pipe/muffler. IF the motor blows up....Scrap it! ($99 is cheaper than fixing it). The 'gear' most likely will be spec'd as well. What would we expect to see as 'max' rpm?
