the lifan would give you years of trouble free smooth 4 stroke power and operation and the denardis/morini would be more prefomance oriantated but would still be up to the task !
mabe a 50 - 70 cc demo saw motor rear mount and chain drive ?
I have been looking at this Lifan and it is one awesome engine. I wish it was a bit lighter so I could justify putting it into a normal bicycle frame, haha. Since BarelyAWake's post I have been looking into 3 wheeled recumbents and it is looking more and more appealing. I'd have to find someone who could fabricate a frame for me and I have absolutely no idea how much that would run (probably more than I am willing to spend).
When all is said and done I planned on spending about $1200 - $1500 on my bike and then some upgrades later like a custom gas tank which runs about $300 alone.
