| ok - I'll give you an idea
I am buying second hand a Polini 50cc Evo, 15.0hp race preped engine for 850 - which includes fitting & testing.
As for the pipe - a pipe thats worth 550??? forget it mate - a polini race pipe is only 280 ~ 300 at most.
Now since its Bizeta engine I'd normally throw another hundred on that 850 price, but since who ever gets it will need to fit it all up..... maybe 850 would be a fair price.
Does the engine come with everything??? ie: carby, v stacks, clutch & housing & coil? Is the clutch setup right??
Pictures would help as well mate - also for everyone else - this engine will fit stright in to the following china bikes:
1) Banshee SHO
2) Dream Rep
3) Blata Rep
And if you are seriously wanting to get this engine - all I can say is HOLD THE HELL ON!!!
ps:- wining racers is not all the bike - 80% of racing is between the ears. |
