Hello, First time posting here.
My father in law has built one awesome xs650, but is having trouble getting it to idle properly. The entire motor has been rebuilt and custom intake manifolds where made. They each come out and bend about 45 degrees to the outside of the bike and are steel. The carbs are secured to these with some heater hose and hose clamps. Now the bike runs ok, but when sitting at idle it likes to surge up and down like it has some type of air leak. Could the design of the intake manifolds contribute to this any? is there something common we should check before tearing the motor down again ? I have some pics on my phone I will try and get posted.
