Diagnostic suggestions wanted - 2005 DL650
My 2005 Strom 650 has 120,000 miles on it (yes, really). Its given me almost zero problems until a few weeks ago.
It starts and idles fine, but when I give it 3/4 or more throttle it won't rev up and has zero power.
I've been too busy to ride lately (and it's miserably cold), so I haven't done anything to look into the issue yet. I ran a bottle of fuel-injector cleaner through it to no avail, so before I start throwing parts at it, does any one have any suggestions on where I should start looking? The two cylinders seem to be running evenly, so I doubt it's a plug or coil issue. My first thought is fuel system. The pump pressurizes when I turn the key and sounds the same as it always has.
Any suggestions welcome. Thanks.
