Rider must accept some responsibility here then as if it had been loose for some time surely something would have been noticed or felt and should have been checked. I once had a loose clamp bolt and could feel something was not right so I went through all th3 bolts until I found the loose one
Having the diagnostic leads and software also makes life easier, maybe find out if someone local to you has a set before you decide otherwise it could be an issue for you down the road
Spares can still be had, it depends what you need. I have never broken anything major, just consumables, sprockets etc, which are common across a lot of bikes. If the price is right I would consider it. Mine has been a great bike, my 2013 is my second. It's only a 280i, not a 290, is it the one on kijiji?
Clutch fixer nut is in the centre of the clutch basket. To secure it use a torx wrench pushed through the crank breather hole, give it a tap to secure it on the clutch fixer rod hole and then undo the left hand nut
if you gave an early 2012 you may not have the nut as the rod was an upgrade on the 2012 model
sounds like you may be on the right track with a pipe to go inside the termi - lewisport have a similar product on their website at this link: http://lewisportusa-com.3dcartstores.com/GAS-GAS-TAIL-PIPE-EXTENDER-FOR-SPARK-ARRESTOR-2011-CURRENT_p_935.html that is for a gas gas
I would imagine that as long as the pipe is not too thick and restrictive that it would not affect performance too much
I always wondered how effective a ramped up aaa battery would be to precharge the system. I don't have any issues with a 9v lithium that pressurized tge fuel pump before kicking over. With the aaa system does the fuel pump make a noise when you press the button or does it just energize the wiring for a spark?
