I have a 89 virago 535 it will start and idle fine but when i give it throttle it dies. Unless i hold the start button in. Someone please give me some suggestions on what the problem may be.

I had a 535. got it cheap because the carbs were sticky. Remove the diaphram caps and check that the vacuum operated slides are freely moving. Unlike most bikes they are led on their sides and need ptfe spray to keep them free.

Change the plugs if you havent yet done that, as that improves performance under load.

If these dont cure it then check air filter and carb jets.
