I am also having some troubles with my shifting. Its the opposite for me though. I recently installed a new OS .18 motor in my Fun Factor, but now, it seems that the transmission runs or starts in 2nd gear all the time. I do hear it shifting when doing a long straight acceleration run, but, the shift not noticiable at all, like its barely even shifting at all. I made only a minor adjustment, about 2 turns more, on the shift point. Would that help , or hinder, the proper shifting. What's the correct shift setting for an OS .18 motor installed on a Fun Factor. Thanks to All.
