I am building a boardtrack racer and am using a worksman bike i'm not sure if I am eventually going to do the whole stretch and droploop thing but for now I am going to keep the frame as is and will be dropping a china girl motor I am really tempted on going with the GP50R I mean 9hp seriously?! and since I found the complete worksman for a real steal ($40!) i think I can afford to spurge a little with the pricetag close to $500 with sipping. anyhow does anyone have any info on this application? will it fit in the smaller worksman frame? it looks as if it is pretty compact but never seen one in person
