There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Rear tire air valve

When it comes time to replace your rear tire .... before the new one is mounted .... add an Angled steel Mtc. stem from " Kurveygirl " , about $10.00 ... I have done this on every Spyder I have owned. .... The first one I removed the old valve and patched the hole .... then I just left the Oem valve, and put the new one opposite it..... The new one should be put on the other side of the rim,( the disc side )and away from the raised part of the wheel so tire machines won't hit it ..... Mike :thumbup:

do you have a photo pease ?
For the time being, you can use an air chuck used for airing up dual tires on a truck. It's the right length and has the correct angle to easily access the rear tire valve stem. The best thing about it is that you don't have to get down on your knee to air up your rear tire.

Thanks for asking this question. Every time I have to get on my knees to fill air in that rear tire...I wonder...am I doing this right? It shouldn't be that difficult.

I have wondered if it would be possible to fit a valve into the side of one of the spokes, pointing directly outward. This is done on BMW machines and would make inflation much easier.
Good idea, but there's no easy way of making that work on our existing rims! :banghead: At least, not without drilling into/modifying the rim itself & potentially compromising the strength of that spoke.... and since the rim wasn't designed with that in mind from the get go, probably making it a little more difficult to achieve a good wheel balance too!

Following this thread for a good answer if there is one. Surely BRM could have done a better job on this one. If you are one of those 'old' seniors, try airing up that tire a time or two, it will sure test your religion. I mean, come on, proper air pressure is a safety thing, why make it so difficult? They could have angled the valve or something!
That's what I use.
My issue isn't so much airing it up but getting the valve stem in the small area where you can actually access it. This is one of the reasons why I got the FOBO 2. I don't want to have to move the bike forward inch by inch (releasing and resetting the parking brake, running around to the other side of the bike, repeating the process, etc) before every ride. I check the FOBO and call it good.

For the rear I use one end of a dual fill hose with clamp-on chuck. Not that much of a problem to slip the chuck on and off unless you have gorilla size fingers.

Until you can get your air valve moved or if your somewhere without the right sizes chuck, gonto the Harley store and get a stem extender as used foyr an Ultra. Harley has the same problem and have 6" flexable extention. Costs about $10.00. I keep it on the Spyder with my air gauge.

Here's a link to the extension: https://www.harley-davidson.com/us/en/search.html?format=json;i=1;locale=en_US;q=valve-stem-extension;sp_cs=UTF-8;sp_staged=0. I bought one as soon as I bought my Spyder and shortly after I bought a Harley emergency compressor that has an identical extension with it.
That would be it!
As MONK mentioned, I also run FOBO's, and therefore I know at any time what my tire pressures are. If you have any experience with FOBO's you know that these spyder front tires have very little air in them, volume-wise. Merely the act of checking their pressure can allow enough air to escape and drop the pressure by a pound or more if you're not careful. In reality, a pound or so is not extremely critical. Because of simple ambient influence, your front tires can change one or two pounds all on their own while riding your spyder. But if you are like some of us who are overly anal, a two-pound difference can be worrisome. The rear tire can heat up to as much as four pounds from cold to hot after a half hour or so of operation. So, if you pre-check your tire pressures to what BK911 has mentioned here numerous times, you should be good for any environment. And the tool that Bensonoid pictured is about the easiest and least expensive way I know of to air up my tires. I keep one in the frunk at all times.

Yeah, along the lines of Jaybros amd others, I bought Lamont’s portable compressor which comes with a short, flexible hose, and you can preset a pressure. When FOBO tells me rear pressure is low, I can set the required pressure and screw on the flexible hose without even getting down on my knees (I sit on a low stool). It’s a bloody long way down to the floor for me 
..... works a treat. But there is still the pain of getting that valve stem in just the right place :gaah:

On a side note, I was riding yesterday in 45* weather and my FOBO alarm went off. I keep my rear tire (still a Kenda 
) @ 26#. FOBO was screaming at me that it got to 31.2#. Not sure why it was so upset although that did seem to be quite a bit of increase considering the ambient temp. I was less concerned with that than I would have been had the pressure dropped. According to FOBO, it's now back down to 26.5#. I love this FOBO app.
