I have a question that I hope can be confirmed, and I hope I am right. I just picked this bike up and it runs fine when warmed up. It doesn't have any issues with loss of power or anything, though it does smell a little rich. I just went out and tried to get it started this cold morning, and I couldn't get it to turn over. My buddy and I got it bump started and it was idling really low, in danger of stalling out. Tach was reading around 500rpm. When I would go to apply choke, the engine would die. If I tried to give it gas too quickly, it would die. However, after letting it run at that low idle for a minute and eventually slowly rolling on the throttle to let it warm up better, I was able to get it running reliably. I have been working on running a can of seafoam through the tank, and I am on my second tank right now.
Anyways, I believe with the rich smell and the choke stalling the bike, that I am in need of a new air filter. Can any gearheads confirm my suspicions? I work on bikes a little bit and this sounds like it would be right to me, but I just wanted some third party confirmation. Any other things I should look into? I have a repair manual and it looks like the tank needs to come off for a filter replacement which would lead me to believe that it probably hasn't been serviced in a while because it's a bit of a PITA to service.
Thanks in advance.
