Question:

Riding a motorbike without exhaust system?

If there‘s ANY damage to the motorbike engine if you ride it without any exhaust system.And one-time-only vs long-run of doing that.I mean riding it without the exhaust system at all, not just the muffler/ silencer part.Thank you for any answer beforehand.

Answer:

If the battery is on it's way out the door, the constant drain (though minimal) would cause the problem you describe.
Don't do it. No exhaust means no back pressure/resistance in turn cuts your power drastically also changes the amount of suction in because of the easy flow out. Thus changing your fuel to air ratio. Yes it will burn your valves and possibly bend them from the temp change. Short ride like two minutes might be alright. Long ride 2 or more minutes means more damage. Also having a open head while riding is asking for things to fly inside your motor water, dirt. ect. Fire flying out also can start your bike on fire from feul, oil, grease coming from the neck bearings. Heat can also melt your plastics, throttle cable, brake cable/line. Lots of tickets too. LOL If you rip it on Private land they may close your trail.
Alarms don't use much battery power unless they are defective and drawing extra current, have it checked if you suspect that is what is causing the problem or it may be something else in the car
It would PROBABLY distort the air/fuel mixture, Every time you ran it.
Its really not a good idea, you could do it if you absolutely had to but it is really something you should avoid, a short run may be ok, though it will not run properly and will have a severe decrease in power, any longer and as others have said it can cause serious problems, such as burn the valves out.
