How do you make a 1995 ktm 620 easier to start?

Answer 1

The problem is your carb. Most likely you have an Edelbrock Qwiksilver. The carb is fine,
but not for this application. In the case of both the 400 and 620, the carb was excessively
lean in order to make it through EPA emissions. The cure is to swap the carb with a KEIHIN FCR. You can get a kit from sudco.com or rig one from a Motocross bike. A 620 with a Qwiksilver may take 12+ kicks to start. A 620 with a FCR may only take 3 kicks to start.
