Newbie to forum but not to motorized bikes

Hi I'm Blakenstien and I've been riding my motorized bike for just over a year now.It's a Bridgestone Titan 35cc rear mount chain drive with centrifugal clutch.[motor titan bridgestone is made by MITUBISHI]-has chrome moly. sleave in cylider really thick one too.That tiny little motor sure has a lot of guts to push me at 30 mph.Thru the winter it was really outstanding and Iwas amazed.
I also have a 48cc Titan that is brand new and still in the box I'm just dying to bolt it in but winter is coming and I want to get my 35 running to perfection. After browsing this forum I've seen other types of systems that really impresive.Thoase center mount motors with manual clutches have me drooling.I see that they really get a lot of wind for cooling and that really important for two cycle motors.P.S.......synthetic motor oil voids the waranty on my motor.Manufcturers tell me not to use it

Hello Barelyawake-from Blakenstein. I have pictures but still dont know how to post them and how many Ican post.Two are of my World cup656Proflex with Vector Girven front end-no motor yet-can only electrify,no gas motor of any type will fit.Two are of my motorized Harrow HHHHopper with Marzochi Bomber front end can't see motor very good --it is a chain drive P.S.Last spring I installed a brand new steel head set on front end .Not enough time and space to discuss other issues u mentioned at this moment.

Thanks for the info,muchly appreciated......I still have oil issue to resolve but not at this moment.
