Picked up a baja warrior and im pretty sure the engine is shot , it looks like it may have been left outside a few years or maybe under water at some point. Everything is rusted. I have never done a engine swap and would like to try and put a hf predator motor in it at some point. I wanted to know if i remove the engine from the bike now , what parts should i keep to mount and put back on the bike with the predator engine ? Do i need to take the clutch off the old motor bc i plan on most likely picking up a new clutch ? Are there any screws or parts behind the clutch that i need to mount a new 1 ? Do i take the chain tensioner off and the gears next to it ? I will try and buy some rust remover for the sprockets and gears bc they are pretty rusty but a nice little list or pics of what i need to keep would be great help. I will buy new chains they are rusted and on there last life. What chains do i pick up for direct fit with predator motor ? Do i save the whole throttle spring and mechanism attached to the motor ? Sorry for all my questions , trying to do this on a super budget . - thanks
