Just reading the inital post again..
How did the bike run when you first bought it and rode it 3-4 times? Has it ever been right?
It appears that you are saying that the bike will not idle. Most probable cause, rich pilot circuit. Try leaning it out on the air screw or bumping up the idle adjustment screw (lifting the slide).
when i bought the bike he whas running great. the problem started after 3-4 rides.
i opened the silencer but found no blockage. the only thing i found where a few cracks in it.
now il check the forend off the exchaust for any blockage. got any tips on cleaning this out?
