I bought a 2008 Kawasaki ninja 250r. I just notived there is some black dust (carbon/coalish color) under the exhaust pipe, what could that be?Also, the owner told me to run the motorcycle for 20 minutes every day, if I wont be riding it that day, any reason why? and do I have to do this?when I brake, do I need to pull in the clutch and then brake? or it doesnt matter?lastly, is there any way I could know when the last oil change/tune up was done? I wasn‘t given any maintenance records, but the oil level seems fine.Thx.
always give a newly purchased vehicle an oil filter change. Do as much of the work on it yourself as possible. Not only saves you money but you learn a lot more about the bike ( it's fun) The only reason to run the bike daily is if the battery is dying or something is flattening it if left idle for a couple of days. When you slow down you need to change down as well so you're in the right gear for your road speed. It's no good being in 6th gear at 20 km/hr, any attempt to accelerate the engine will stall changing right down though the box with the bike stationary can sometimes be tricky.When you stop you should be in first or second gear. If sitting stationary for a while drop back into neutral release the clutch lever.
Change the oil and do a service on the bike so you know when it was done and can start tracking it! If you are just slowing down a few MPH or so no you don't need the clutch, but to come to a stop and for other gear changes yes you need it, or you will stall the engine. I see no reason it would need run for 20 minutes a day NONE, other than if you want to waist gas! All engines make soot its part of the combustion process and near or around the exhaust tip you are seeing some soot its more than likely normal, and an engine that uses carbs like your bike and does not have catalytic converters in the exhaust will produce soot and you will see it at the tail pipe.
The carbon color is a byproduct of lean combustion. Not uncommon on today's engines. If you have a fuel injected bike, it's most likely OK. If it's a bike with a carb and an aftermarket pipe, you probably need to have the carb rejetted correctly. No, do not run the motorcycle every day if you are not going to ride. That is the most stupid advice I have every heard. Your bike will be just fine sitting there without running it for hours, days, even weeks. You can actually damage the bike over time by idling it without going out for a ride to completely warm up the whole drive train. Do not listen to the person who told you that about anything motorcycle. You need to pull in the clutch to change gears. Yes you can do clutchless shifts, but you risk damaging the transmission if you do one wrong. You can slow with the brake without pulling in the clutch to the point that the engine begins to lug, then you need to shift. If you are slowing to a stop, you can pull in the clutch and use the brake to come to a complete stop - shift down as you slow - you don't have to release the clutch every gear if you are going to use the brake to come to a stop. You need to be in first gear just before coming to a complete stop. No. The previous owner was an idiot. You need to just start fresh. Change the oil and start your own mileage countdown for the next change - 3000 miles or jus before winter storage if you don't ride that much.
