So, my son's 2012 G650GS has sat for a few months and won't start. Battery is probably defunct, but the engine cranks over with a jump.
We took off some Tupperware and got to the throttle body. I poured a couple of teaspoons of gas into it and the bike ran for a couple of revolutions. As a result, My diagnosis was clogged fuel injectors.
I put some Techron and a gallon of gas in hoping it would reach the clogs in a day or two. Any other thoughts? We dd not plan on this scenario and did not drain the tank. Is there any product one can safely spray in the throttle body for this situation? Amy other advice?
Might be the fuel pump, the 650/700/800 had a rash of fuel pump failures that either froze the pump up or pumped metallic particles into the injectors. (can you hear the fuel pump run for a couple of seconds at first key-on)
Is fuel actually getting to the injectors?
Have you tried holding the throttle to about 1/4 throttle while cranking?
