HAPPY NEW YEAR!
I read your thread about replacing the caskets with thin aluminum explain the purpose and or benifits, how thick should the aluminum be? and send some other tweek secrets.
I contacted PKLTD about the PK 80/68.5 jet silver slant engine they offer and was told by a rep that the engine would have to be ordered from zoombicycle.com
as they are the same Co. so the engine comming to me is the ZB-80ccS-SR limited addition silver slant, are there any differences between the two?
Another Rep sent e-mail stating needle & roller bearings were used in the engine the casting diffenately are cleaner(judging from all pic's)
