Re: arnt all these 70cc motors the same
I think the kits you are talking about could be real 80cc engines?
They come in labled designations of PK-50, 60 70 & PK-80.
I havent opened one up to measure the displacement tho... But they DO look bigger!
I will say this, I use the PK-80's & they're a lot faster than my friends engines!
They are the best deal that I've found...
Also, I don't know if chris hill does anything special to his engines?
