1. Ride the bike as it is with the pipes , but make sure the DB Killer is inside the exhaust can and also fit the high flow air filter, just checking also that there is no air leaks around the engine manifolds (spray carb cleaner on them)
Ride for a little bit , check your plugs. Take pics.
Ride again after cleaning the plugs and see the colours again.
Show us we can then access how lean or rich the bike is , sometimes lifting the slide needle one notch away from the carb bowls actually helps the midrage and enriches the bike a little more.
Wish i did a tutorial for it! (like i did for the 125cc here but principle is the same on 650cc)
2. That means the starter motor should not be jammed ? – Take it off and see if it whines freely when connected to the batter directly away from the bike.
If the starter motor is OK, then consider having a quick look at the flywheel sprocket (open the casing after draining the oil first) and see if the teeth behind the flywheel have any missing , i really hope not . I also don’t expect the “sprag clutch” that sits between the flywheel and sprocket to have any issues
I mention this because it does happen on rare occassion the starter sprocket behind the flywheel and its mini clutch to jam.
If all looks good, then it means the battery is too weak (cells inside caused voltage to drop fast) or just simply too old or too small (must be size 14BS factory size battery)
Or easy option, replace the solenoid relay , it is usually tht 90% of the time. Common part to replace on any brand big cc bike.
3. Take a picture of the mystery object 😉 and show us
