tune up cost

Hello Joey, that is a regular price for what any dealer does. Every 20K miles it will hit you. I am having my 60KI mile check up done as I type.

As for you battery question, I am on my 4th one so far and have not yet found the "one" that meets my cold weather riding style yet. Lithium Ion is surely not the way to go as none of them are rated below 40F.
 
Not sure why there is such a discrepancy between bikes for cold weather starting. I have the original Yuasa YTX20L-BS (270 CCA) which came with the bike (2012 Roadster). It is still going strong. I keep the battery on a Tender all winter. Rarely use the Tender during the summer. Just went outside to the non heated shed and fired the Rocket up. Did it labour a bit during cranking, yes but all automotive vehicles labour when cranking in the winter. Temp was -10C which is 14F. I have done nothing to the positive or negative leads to enhance starting. Just run a good quality synthetic oil.

My previous America lasted 7 years on the original battery using the same practice mentioned above. I finally replaced it because people were telling me I should and it was beyond it's usable life. Guess what, the replacement non Yuasa only lasted the summer and died.

I know I'm on borrowed time with this battery but hate messing with something that works. I will replace it with a Yuasa YTX20HL-BS (310 CCA) when it is needed.

If I ever do get caught with a dead/low battery, I carry an AntiGravity XP-1 booster battery to get me going.
 
Found this a while ago.

Since the operation of a battery is based on a chemical reaction, temperature plays an important role in performance. The ideal operating temperature for an automotive battery is 26.7 C (80 F). This is when the battery operates at maximum efficiency.

It’s getting hot in here: Heat typically accelerates chemical activity, but higher temperatures also speed up internal corrosion within the cells and reduce the life of the battery. This is particularly true of batteries that repeatedly reach high internal temperatures, and once capacity has been damaged by heat, it can’t be restored.

Cold bogs batteries down: Just as heat speeds up chemical reactions, cold temperatures slow them down. That’s why a battery can become sluggish in winter, even though its state of charge may remain unchanged.

At colder temperatures, the battery’s ability to provide sufficient power to start and run a vehicle is diminished. That’s why automotive batteries are rated in CCA (Cold-Cranking Amperage). This is the amount of current a battery can deliver for 30 seconds at -18 C without dropping to a specified cutoff voltage. Obviously, the higher the CCA, the better the battery will perform in adverse conditions.

Batteries can freeze: A fully charged lead-acid battery can survive up to –50 C, but a battery with a low state of charge can freeze at –1 C. When the water in a battery freezes it expands and can cause irreparable damage to the cells.

I find that batteries here last less than they did in the UK and HEAT has been my cause - on both my ex Softail and the R3. On the Softail the battery was surrounded by the oil tank - and I am seeing underseat temps on the R3 well into the 50's °C and even the 60's. that is 60° Sulphuric Acid - It eats things.

LiFePO4 chemistry Lithium batteries should be OK down to about -17C (0F). I have never had a problem with my homemade LiFePO4 on the Guzzi even well below zero.
But plain generic Lithium Ion can and will get funky below 5C or about 40F. This is what I currently have on the Rocket.
Usually the Lithiums will warm themselves up a bit by making them work a bit before hitting the button.

But tbh if it's that cold I always have a Lithium Booster pack handy - which I keep with me in the warm.
 
Made it here with no trouble not a bad ride.
If it stays this Cold I am sure that it will not start with out e jump

The battery is rated at 330 cca that is in my rocket

I guess I will have to get the 700.00 tune up
Not bad for a 14 year scooter
