couple questions

my bike let me down yesterday, or I let it down.
first it does not have a maintenance free battery, the levels got low and it would not start before work. tried push starting it, no luck. man is it pretty heavy when you have no hill. a lot of backfiring so I decided to pull the plugs and they were pretty nasty, they have about 6000 miles on them. not a lot I wouldnt think but then again the way these bike backfire maybe so I changed them with new ones.
first question, without a torque wrench how tight should I tighten them? hand tighten till they stop and then maybe a 1/4 turn or so?

next question is does anyone have any experience with the agm batteries autozone sells for 79.99. they are a little shorter than the stock battery and I'm thinking because it is an m/f battery. but also a little wider. is 79.99 about the right price for a M/F battery or are there cheaper ones of good value. I prefer autozone for car parts but they dont have a lot in the way of bike parts of couurse and our local bike stores rape you. I did buy my charger at autozone for 31.99 as I went all summer riding without charging at all longer distance miles but the past couple weeks I have only been riding 12 miles to town and back everyday. so I bought the charger, as soon as I can afford it in a week or so I will get a m/f battery.

Spark plugs should be tightened to the light "German torque spec" Gutensnug, verses Gutentight. If you turn them in by hand until they stop, with a socket turn about as much as you can pull with one finger six inches from the head of the ratchet without straining. Use two fingers if strength is in question. I also add a little anti-sieze compound on the threads when dealing with aluminum heads, just remember a little goes a long way.
As for the battery, that's the same one I'm looking at for the same price. I didn't see any noticable issues, but then I haven't picked it up yet.

okay, charged the battery for about 4 hours (still wasn't fully charged, I'm impatient). changed the plugs and cleaned the air filters, actually i just squeezed the excess oil from them and flipped them upside down. bike fired right up. gonna drive the cage a day or so and let it fully charge now but will trickle charge it every night until I can buy a m/f battery in a week or so. 30.00 more dollars but well worth it to not have to check the fluid levels in it often.
not sure if the one at autozone will fit in the battery box on our bike though as there is not much more extra room and it is a little wider but I could be wrong. if it fits let me know.

Try the one from WalMart. Mine was about $60 or so and the only issue is that I had to put it in backwards as the polarity was reversed. The battery leads for the bike are long enough to do this without strain. That and there is a plastic base that is held on by double sided tape that you need to remove to get the hold down strap to go back on. I've had mine since January with no problems.

I went to BatteriesPlus and got an exact replacement in the M/F style. It cost me about $68 after tax. BEST $68 bucks I have spent on my bike! I found the part number and then researched the internet until I found a place that carries our batteries and had the best price. I ended up at BatteriesPlus about 2 blocks from my house.

(Note: I could have gotten it cheaper, but I forgot to take the $4-off internet coupon I found and printed LOL)
