Blew out the injector, a bunch of blackish crap came out as well as one chunk of brownish stuff that looked like resin. Bike idles and doesn't stall now, rode it for 45 miles and no issue, thanks for the tip Letter J.
Fuel filter looked pretty dirty, definitely replace that this week given the black crap in the injector. Not sure if I should install the CA Cycleworks pump or carry it as a backup, not sure I would even want to do that job outside of the garage though.
Now that it has me spooked I noticed some clacking at idle, wondering if it is the chain smacking the case a bit? Anybody else have this type of noise at idle?
