2016 Spyder RT-S has a misfire and dumping gas. No codes, uses gas very quickly.

[GDoc]

I am new owner of a 2016 RT, so the 1330 engine. I bought it as is. It has 5,500 miles, and had not been used very much in the last year.
The bike has basically sat since last fall. The old owner claims that the bike run fine just a few days ago. I have my doubts about that.
The engine starts right up, but has a misfire all the time, at any rpm. It has very little power. The throttle has very poor response, and the bike slows on even mild uphill slopes.
One big factor is that it uses gas to the tune of 50 miles to a tank.. 10 miles to the gallon. A person following me in a car reported smelling gas a lot.
The tank was full when I got it, very likely from last fall, so maybe 9 months.
It ran just well enough to drive it, so I decided to try and get it home, almost 200 miles, so at least I could run the old gas out and eliminate that possibility.
I put 4 tanks of gas in, in 200 miles with no improvement. 91 octane, non-ethanol gas.
Today I ordered spark plugs to eliminate that possibility. I have it dismantled to the point I can replace spark plugs and can get to the injectors (shame on BRP for this design). The air filter looks new, and even though there was mud-bug mud everywhere, after a good wash, the engine looks good with no wire issues or rodent damage.
It seems more and more obvious that it has a bad injector dumping gas.
I am looking for some input on the issue. Please don't suggest fuel injector cleaner or cleaning, the injector is open, not clogged.
Can anyone tell me how I might go about finding out which injector is bad, if in fact that is the problem?

Wingerdinger, I hate too say take your Spyder to a good Spyder shop, after you have the Spyder torn down, sounds like your good at working on your Spyder. Me I'm not much of a mechanic. Just north of SanAntonioa town called Boerne, at Coyote Powersports have a Sydney mechanic named Rockie, he knows the Spyders inside and out. My Spyder was running rough, in 2st gear, sputtering but once in 2nd the spyder was fine. I tried some gas additive, but no luck. Didnt check the mileage. Well Rockie replace the plugs, for got the name, supposed to last like 70K miles or more. My Spyder ran like it was band new. Maybe having your Spyder hooked up to the computer at a Spyder shop, might find something out. Just 2 cents, I have a 2016 Spyder RTS SE6 and bought it used with 1348 miles on the Spyder. Now just over 17k miles. I do hear thing noise coming from the garage, my Spyder wants to go for a ride, LOL LOL. Ride Safe Watch Out For The Cagers. GDoc

This post is part of a thread that was posted August 2024. There were many responses, including my follow up. New plugs, injectors cleaned but did not need it.
