No I built the motor mount myself and on my ALBUM I have detailed all the dimenions and material for others to copy..I did buy a back sprocket (Gasman Bikes) already set up because to adapt the gear to the original is difficult and probably unstable and not that strong..Also bought a stronger chain (not Chinese) from BLACKWOODS in Newcastle for $15 for a 10 foot length (post them a chain section so they match it correctly) ..(10 foot is enough for three chain lengths) they also have the links for 33 cents each..Gasman charges $30 for a chain and $5 a link..Difficult build but worth it and they power well with a 80cc motor to compensate for the weight..say its 48cc if pulled over..Good luck..post some pics of your build..See ya ENO (Oz)
