As for the carbs- yeah only 6mo. I completely cleaned and rebuilt them top to bottom in April after I had issues with the pilot jets clogging. I ran it regularly enough with a fresh fuel filter(every few weeks at minimum) with several tanks of fresh fuel through them in that time and it ran awesome. Then it ran crumby once about a 3 weeks ago. Then ran fine the next day. Then the next weekend it wouldn’t run at all and the choke was sticking real bad and not operating correctly. So I knew I had a carb issue again. But in all the time I’ve had it, and in all my time Messi with carbs, I’ve never seen build up like that in that short of time. It’s on the cylinder side of the carbs, intake side is clean, bowls are clean, jets are clean. But needles, needle seats, cylinder side throats and butterflies are coated. Im not sure what would cause that. As for the air filters- I’ve never oiled them. Only whatever oil was on them out of the box. But the bike has ran good when it was running over the last 3 years since I did a pod kit setup on the carbs for the new exhaust. I can probly rule out the filters. At best they may need a cleaning, but even then, not sure I’d oil them or just do a super light coat if I did.
Just odd and annoying.
Part of me wants to just go to a single carb setup and stop messing with these dual carbs. But that’s also an expensive endeavor in itself and there isn’t really much reason these carbs shouldn’t work right short of bad fuel reaction?
I will be going back to non-ethanol fuel in this bike. I used to run it all the time on 90 eth free and didn’t have these issues, but I switched back after the last rebuild and now I see this internally.
It will be the last time i mess with these carbs though. If I they fail again I will be going to a single carb setup. I lose a bit of power with a single setup, but tuning and maintaining is ten fold easier. After I get these rebuilt, I have to lean drop and re-sync them which is a pain to do.
