Re: Bike sitting for 15 years. Need help starting it.

15-years and still filled with fluids?!? You're gonna have to rebuild/recondition the carbs. Most likely, the jets are rusted and sludge/varnish is throughout the system. Also check the tank for rust. Mine is a '95 and I let it sit for two weeks with a half tank and the other half rusted badly.

Keep us posted as to your results and GL with this one...
