I recently purchased a 2011 Honda shadow with only 4100 miles on it in july. Judging from me having to buy a new battery for it, it seems to have been sitting in a garage unridden for quite some time. I've already changed the Oil and tires and it was riding fine for a few weeks. But recently the bike has experienced a tremendous loss in power. It's difficult to get the bike up to 65 mph and hold that speed now. I can't get it to go any faster unless I'm going downhill. Top gear is meaningless, doesn't deliver any further power than the gear before it and may even cause me to loose power going back down to 55 ( I usually shift into top gear around 65). The exhaust is turning blue from heat quite dramatically, if I didn't know any better I'de say it's not getting the fuel it needs to the injectors, thus more air and less fuel, means it's burning hotter. I inspected the fuel tank, full of rust, working on cleaning it out now. I suspect the fuel filter may be clogged but I can't seem to locate it. Anyone know where on the bike I might find it? I'm very new to the motorcycle world so any help is appreciated!

I SEE. So remove top plate here, filter shall be inside the fuel pump just under the plate? I'll post a picture of the filter screen when I get to it. Gonna work on it this afternoon when the weather cools down.

I went with evaporust actually, soaking it overnight. If that doesn't work I'm going to use electrolysys. Interesting you mention seafoam because I purchased some yesterday with the injectors in mind. Great minds think alike I see.

Completed the job. The gain in power was dramatic. Went from barely abled to maintain 65mph to pushing 80-83. I still feel just a little bogged down but I'm a big heavy boi, I'm not very aerodynamic and neither is the big ole windshield😂. Added seafoam and fresh clean fuel. Gonna let it run its course. What other maintenance do you think I could do to gain more power? I feel like 70-90 in a reasonable amount of time shouldn't take much effort. Also, could I retrofit another filter into the fuel lines outside the fuel pump housing? Could make things much easier on the interior fuel filter I just dealt with.
