Ok let me start off by saying I was going to try to drop the bomb by getting a new engine that no one would recognize .Well , Nancy , seems that some people , even here has heard of the wizard 4 stroke and two stroke motors and have had problems with them . I will get this thing going until with any luck my Grunbee Skyhawk GT5 80cc Angel fire Slant Head will be here . Let me say that I would rate the handle bar grips on a scale 1 to 10 an 2. Any correct way to get them off ? The wheels turn true on it. I will rate them an 10 for a wallyworld bike. And will the coaster brake give me trouble ?
