I can understand your dilemma, seems quite daunting at first, once you've had it apart though it becomes a lot easier. It's always nice to have somebody else come to help you, that way you get to make more friends, drink a bit of adult beverage and learn a thing or two, but if that's not happening, don't fret, we can help you through each step of the way. We have all been in your position at one time or another and can understand what you think you're up against. So ask the questions, answers will be forth coming.
To start with, I suggest you get yourself some sort of ABS repair kit, for as you get into this scoot, there will be places that need a bit of help and\or encouragement. That being out of the way, remove the 'tank' cover, seat, side panels and the lower faring legs for starters. Then remove the side covers on the carbs to check the diaphragms, they will most likely need to be replaced. Don't worry too much about how it comes apart and goes back together, that's quite simple actually, seeing as 1)somebody else has already designed it, 2)some person who doesn't know nothin about nothin, put it together 3)and we all have attempted to put things back together backwards and found that it didn't work so well and then had to figure out how it was really supposed to go back together. So somebody on this site may even remember how it was done properly and be able to help,,,, now that leaves a problem as to whether he can type,,, but that's another problem.
