Well my ongoing problem with it running lumpy and sometimes stalling happened again today. I'm beginning to think it's heat related. Rode about 10miles doing a steady 70/75mph. Stopped at tescos to refuel then pulled up in the car park to meet some others. After about 10min we rode off. It was at this point my bike started in this lumpy mode. The tickover was up and down to the point it stalled. Pulling away at a junction and it nearly stalled again. I have to keep the revs up manually when this happens to prevent a stall. When accelerating, when it's like this, the bike pulls but it's a rather flat experience and really lumpy in traffic. Anyway, rode the bike for a few miles afterward doing a steady 30-40mph through windy roads and the bike naturally improved. I'm convinced it's a cooling problem. My bike stops, fan kicks in and shuts down when it's finished but I think the rear cylinder is still cooking. Turn the bike on and I think the rear cylinder by then is so hot that the ECU is shutting down that cylinder until the temp drops - hence why my bike is running poorly from time to time after a stop. Why it's an intermittent problem is beyond me. Todays temperature was not exactly warm either!! Where I go from here is unclear?
So, maybe Buell were aware of this and thats why they introduced a R/H scoop and adjusted the fan to kick in when above 15mph?? They are obviously trying to cool the rear cylinder as much as possible - why? - probably because they've had problems maybe? But what do I know, I'm only the customer!
This sounds like the Earth Gremlin. Go to my post about it. It has taken me nearly two years to find it on my bike. Mechanical things do not, most of the time, do this sort of thing. No logic to it. You have become confused and going off "in all directions" rather than sorting one thing at a time.
Diagnose and prove one thing at a time, in a logical manner, until the fault is found. Even if you have to put the bike back to stock to do it.
Oh and any dealer can void a warranty for use of none OEM parts. That is for everything - bikes, cars, cookers, dish washers, ICBMs, M-16s, etc. If a HD dealer fitted the can then he should fix the problem if it is with the can.
I cannot remember all the details of your bike - year, miles, mods, etc. The bike needs 4k to bed in and, IMO not fully run until 6-8k, is still running very hot. Tracing an intermittent problem is very hard even "hands on" and it will be almost impossible via Net Posts.
