Installing Engine Kit on Kent La Jolla This is meant to bring light to a few specific modifications that have to be made to build this bike. The Kent La Jolla is a great bike to start with! Its lightweight aluminum frame feels great at speeds and is easy to handle on turns. Plus it’s a great looking bike, and did I mention it’s SO LIGHTWEIGHT! 1. Shaving the rear fender is required to make room for the new chain. You will have to remove the rear wheel when you’re installing the rear sprocket. This is the perfect time to get a hand grinder and grind a channel in the fender to make room for the chain. From the bottom side start grinding 4 inches above the frame, and from the top start grinding 3 inches from the top of the frame. Make sure to wear proper eye and ear protection! 2. Since this bike has a smaller shaped frame the carburetor does not fit into the frame. You will need an offset intake manifold to move the carburetor to the side of the frame. Simply un-bolt the stock manifold and bolt on the offset manifold. Having an offset manifold also gives your engine more bottom end power!
