Thanks for the photos great help. As for what power and rpm: Just going to see what I get as long as it is bullet proof. The miles we have to travel out here in the bush take their toll on little motors. You tend to get them out on the hiway and stick it to it just getting from a to b. The closest main town to me here is Roma and that is 3hrs drive away. So quicker a bit torquer than stock is good, reliable is key.
Thanks again.
