Does anyone know how to put one of these together because i would like some advice or instructions on how to do this. Also aproximantly how much would this cost.Thanks

 

Or is ould say an engine swap with an Yamaha r1 engine or what is the best bike engine to put in.Thanks

 

I put a busa in a DS frame becouse of the size and strength of the DS frame I am not sure how tall your engine compartment is you will probably have to go with a smaller motor and raise your top frame rails and lower your bottom rails in order to fit a street bike motor. Or you could go with a big motor and raise and lower stuff more but in the end it won't look rite becouse of the plastic and stuff not lining up rite.
