I can get hold of engines and parts cheap vx engines for around £150 or less complete ! i can also get parts cheap so tell me what you need and i will see what i can do the parts i can get are mainly gilera and piaggio parts but there is the odd honda ect.
no cranks mate the parts i get are second hand, i do have a full runner engine fully rebuilt with c4 bearings only done 250 miles since i might sell it has a 50cc hebo manston with only 30 miles on (not replica) pm tuning crank and flowed cases i might take the cylinder of and sell the bottom end on its own if there is interest
