Hi

When I went to pick up my bike on Saturday 12, I noticed the front tire was pretty flat. Made a beeline for the nearest
gas station. Here you have to pay $1.50 for the privilege of activating the air pump. Sure it's not the same in the USA !
Anyway noticed there was this bulbous air valve and for the life of me I could not remove it. Just kept on twisting
and doing nothing. Managed to screw off the top part ( inadvertently) and noticed a ( watch) battery. Anyway after
10 min of wiggling finally managed to remove this thing. I was just looking at the owners manual and this bulbous
goodie seems to be the stock air valve. What is the battery inside it for. I removed the air valve and just hooked up
a right angled valve that I had previously bought. I also removed this bulbous air valve from rear tire. Do I need
to put them back or can I keep my right angled valves in place ?

My 1100 just has your standard angled valve stems. I'm guessing yours may have had some kind of low tire pressure sensor on it. Maybe some Strat owners can chime in but I'm thinking as long as it holds air you should be good.

And I agree on having to pay for air here in Canada - ridiculous.

There are many aftermarket TPMS for motorcycles. Some use cell phone to monitor and others have some type of device that mounts to bike. They are good for keeping an eye on tire pressure and not having to get gauge out. Below are a few samples.

In the USA some states made it illegal to charge for air to fill a tire, because driving with a low tire is so dangerous.

On a 700 mile road trip in a car with a slow leak in a tire, I found that Sheetz gas stations all have free air, good prices on gas, clean rest rooms, and good coffee.

You must have been in PA. lol

Saffer, the battery is for the after market tire pressure monitoring system (TPMS).
Here's the thing, without support, it's not a good idea to put a 90° valve on with a TPMS. Centripetal force will put a downward pull on the valve and it could cause you problems.

Thanks for the input gents-the ones on the bike are the "Ogo Bike" ones. I removed them from front and rear and just put on a regular
valve cap . Will put on the right angled goodies when filling up air. All bikes should come standard with a 90 deg valve stem.
I could not get the hose at the gas station to get anywhere near the valve stem-bit ridiculous !

what kind of wheels are on your bike?

I cant imagine a wheel from Yamaha that you cannot get a standard air chuck on the valve stem.

I assume its a cast alum wheel?
