Hey everybody,
I've got this Huffy Verona Comfort Series frame and I was wondering if it would fit a 66cc 2 stroke engine? Pictures uploaded has a Predator 212 and the BikeBerry 2 stroke silhouette for scale. I was thinking of buying the California Motors Wildcat kit and eventually the SBP jackshaft running to a 3 speed. The old derailleur, rear wheel, and brakes are completely knackered so I figured I would motorized it. The silhouette fits inside the frame but it seems like a tight fit. I tried searching and couldn't find any posts regarding this model of bicycle so I'm posting here. If this isn't the right section to post for this question I'm sorry.
