Told you it would start. I think your plugs are fouling, causing the starting problems.
Fouling can be caused by a number of things such as mixture, however from your previous posts about the charging system you may have a weak spark that can result in plug fouling.
As I have said before, take your bike to someone who can give your machine a damn good service and get all those little niggles sorted. Summer is on the way and you don't want it to let you down.
You got the bike for a good price because of these niggles so I don't think you can complain if you have to spend a couple hundred getting it sorted. You wont regret it, but you would if you bought an RD!
