Gti has starting issues. I plug in key and get 2 beeps. Try to crank and most times it makes one knock and the unit beeps one time. Then have to remove and reinsert key to get two new beeps. What does the one beep mean. I purchase this unit used and have no books for it. Also, It is hard to crank and requires a lot of choking. Usually after you get it warmed up it runs fine. The new issue is getting it cranked and keeping cranked to get it warm. This beep issue just started receintly. I haven't been the one riding it so can't tell what might have happened.
