Digging for problem, ST-S

[damnyankee]

2013 ST-S,SE-5 6K miles. Was a nice day and decided to take bike out. Few miles down road
suddenly was getting loud under motor and lost power on hills. Seemed to not want to shift on it's own. Pulled over and did quick look at exhaust and oil check. Really bad smell that was neither brakes nor gas. In parking lot, started having misfires and loud noise now intermittent.
Limped home slowly while daylight, misfires and loud noise getting worse. Smell still there as pulled into garage.

First found plugs were not iridium so decided to do plugs/wires. Waiting for shipment decided to take more panels off. Found left side panel below seat had melted plastic edge not really visible with panel on!! Right near belt and exhaust gasket. Now suspect gasket issue.

Will take any advice and will update the end result. Initially heart broken picturing tranny/motor problems, or some crazy electrical unit, now some hope it's not that.

? Does the Spyder still have the 2013 panels, or has it been up dated to the 2014 panels?

Inspect the exhaust on the left side. There have been 2 or 3 reports of the pipe failing at the weld.

That & part of the belt guard coming loose & riding up belt to melt by pipe & other forces.

Have to agree with billybovine on the exhaust issue. The weld and the Y gaskets will give those symptoms. Loud with popping and backfiring. Could also melt the panels if blow-by is direct to the panels. The smell depends...maybe the plastic, clutch which could be something to do with no power on hills but would smell like burnt cork. Let us know what you find. The plugs and wires will help either way....

See picture below and look at the header pipe, in the area circled in red.

Well, a few places to go. Got shipment so putting new wires, plugs in and oil change.
Hope bike running will show where noise comes from. Definitely have to check the belt guide.
LOL, off comes bags and more panels.

Good luck with the repairs: please let us know how it all works out!

Well, think I have it. First thanks to all for advice. Does have 13 panels still. Was not belt guard
but now I'm watching the belt, a little too "worn white" on edge. Welds seem okay in spite of what it was.

While it looked okay not running, the pipe slip joint, as brp calls it, ie exhaust gasket of sorts, between two pipes was loose. The collar clamp appeared tight but under running load pipes
would let exhaust leak BECAUSE, someone had removed the spring.

Damn- feel stupid as I was not the original owner and thought I had checked everything out.
Guess it's possible spring gave up while I was riding. I've done enough aftermarket slip ons with springs to know better. So panels off I've had a chance to do some tightening and cleaning but seem to be forgetting something??? Oh right, time to ride this thing!! Again Thanks all.

The left side never had a spring from the factory and does not need one. Install one if you like. By your description was loose clamp was the cause.
