You did not clean and over oil the air filter in the last few day did you? Cause that can cause this also.

The back cylinder on most air cooled motors also runs a bit rich to help cool it. Just a heads up cause you mentioned the plugs being different.
I haven't completely ruled out the battery. It is original and now over 4 years old. I've tried starting it with the battery hooked up to the Tender. But to no avail.

Air filter has not been cleaned and oil lately...still looks brand new.

coiuld be the battery with that age but if you have kept it on the tender when not riding for longer times it shouldn't be the problem.

you could put it on the charger and take it in to get it checked to make sure that isn't the problem.

I made the mistake of putting batterys on a tender and leaving them in the garage last year. I had to replace 3 of the 4, it gets cold here in the winter and really messes up batterys.

was it the battery tender brand or something else? a float charger should have kept them good over the winter. if it was a trickle charger you have to babysit them.

If your battery is 4yrs old you should replace it regardless. Just don't get some cheap BS. Go to the HD dealer and get a nice AGM battery. Should run about $90-$100

Stay away from many other brands... Interstate are rebranded junk. YUASA blows nuts. I'll smack you if you got any auto store to get a fuckin tractor battery.

Are you for real? I hope you mean for a HD specifically?? You are the first one that I have ever heard say anything bad about a Yuasa. I just put a replacement Yuasa in my CBR from the Honda dealer, who might I add, was cheaper on them than anyone else and I get a wholesale discount through everyone else.

Nope on anything. I had a couple YUSAs on my rice and never thought they were worth a shit.
