Just checking, my rear tire drops a pound or so a day, front stays relatively consistent. Something with the wheels? Anyone else notice dropping pressures out of the ordinary? | ||

I have on my rear. Tech advised me it could be the valve stem leaking. | ||

Just to add, I notice this if not riding/checking for a number of days, i.e. after a week the rear can drop from 38 to high- twenties. Front may drop from 36 to 33 maybe. | ||

Soapy water. Find the leak. | ||

I have a tire pressure monitoring system on mine, and the pressure can easily change up to 10 PSI depending on how cold it is out. | ||

Air pressure will flex up and down in the fall and spring. Especially if you live in a region where it gets close to freezing at night and then heats back up near 90 degrees in the day... Go with the soapy water if you are concerned about a leak. | ||

Froggy, Is that tire pressure system you use suitable for racing applications? For example, could I monitor tire pressure while riding and see pressure increases off warmers during practice sessions, etc? | ||

my rear tire was doing that . I finally took it off and kept looking with the soapy water and found what looked like a staple . It was tiny. Just barely leaking out a pound or less a day. Rick | ||

My OE tires were doing that but I could never find a leak. When I dismounted them I noticed a tiny bit of corrosion at the bead. I cleaned them up really well and bead sealed the new tires and it hasnt happened since. | ||

Jdugger, I don't know how suitable it would be for racing, as it requires different valve stems and the sensors themselves add weight. (.49 Oz each according to the mfg). Only thing I hate about it is that it doesn't display the pressure till you press the button on it, otherwise it just says "on". Mounting is a bit tricky on the 1125R, mine is doublestick taped to the fairing bracket. I am gonna do a full writeup soon.  http://www.doranmfg.com/motorcycle-tire-pressure-m onitoring-systems.htm | ||

The only thing I dont like that it is on the outside of the wheel. I will admit that I am interested though | ||

Due to the ZTL caliper, you must mount the sensor inside the wheel (on the front at least). I had them on my Blast for about 2000 miles, as I don't need to change the valve stems for that one. I took it off in about 5 minutes, threw in my backpack and took it with me when I went to get the tires done on my R. It only added a few moments to the tire install time to change the stems and mount the sensor internally. When its installed like this, you would have no idea it is even there. | ||

Froggy -- I'm looking forward to your write up. I'm very interested in a way to get really accurate hot pressures without having to pit out. I wouldn't mind laying off on the back straight and getting a pressure while riding, or even being able to pit out and get it without getting off the bike, leaning it up against the pit wall, etc. Makes being diligent about tire pressure so much easier if it works. | ||

I am sure you would love it then. Occasionally on the highway I just reach up and press the left button, on the unit, it will then display the pressures. When you press the button, it will cycle between front and rear every few seconds. I don't know how hectic it is for you on the track, so I don't know if that kind of distraction would be safe. I didn't get any pics of installing anything. It is nothing really special, change valve stems, attach sensor to the inside rim of stem, reinstall tire. The unit itself just needs a pos and neg connection to the battery or other non-switched source. If you attach it to a switched source, it will need a few minutes to detect the sensors every time you start it up. After that, just find a place to stick the receiver block. It is kinda bulky, and cube shaped. It comes with an adjustable mount to fit on handle bars, which is what I did for my Blast, but due to space constraints I just doublestick taped it to the fairing bracket. I am not sure of a better place to mount it that is out of the way. |
