weird noise

Postby macdaddykeith » Fri Dec 06, 2013 9:53 am



OK, it has rained an awful lot where I live this year. I have not ridden as much as I would have liked this past year. But, since it has turned cold AND rainy, I do at least go to the garage and crank my bike at least every week. I let it run for a bit, maybe listen to the radio and then turn it off. I just leave it in neutral and keep it on the stand. On a few weekends, I have been able to get it out and ride. Recently, I noticed that after I turn off the bike, it makes a weird noise. It is almost like something like a wheeze. Like something that has air in it and it is escaping. It is in short blurts. There is a pause for up to a minute and then another. It may do this for 30 minutes or so. When I ride the bike, it rides fine and there is nothing wrong. After I put it in the garage, and about 5 mintues pass and it starts. What could this be? :?

Could this be pressure built up in the radiator and escaping through the cap? Or maybe air pressure bleed off from the compressor? It sounds like when you blow up a small balloon and pinch the end together and let out air in small 3 second blurts... I don't know...

It's alive....

Mine wheezes,clicks,rumbles and gurgles a bit too...Just like me,it ain't new no more. :lol:

It's pressure changes,metal heating and cooling,valves opening and closing,etc...

It should settle back down when you exercise regularly it next year...Kinda like getting a hibernating bear going...It's gonna grumble a bit..

Just keep a look out for fluid leaking ......(From the bike :D )

It does sound like the radiator cap tho..and possibly look at the overflow tank level...

That is what was confusing. I checked all under the bike, checked the levels of everything and did not see any leaks. I have plans this winter to take all of the panels off and repaint. During this time, I am going to change the belts, and all of the fluids and check all of the things that is a b%$#h to check. I also have a couple of inherited wiring messes to fix. I was just worried that I was getting ready to get some expensive news of something bad... Thanks for the help.

Probably best to investigate it in your spare time.
Really the only thing I can imagine is just what you think..The radiator cap..There cheap..stick a new one on and test again...

Loosen the fuel cap next time prior to shutting down to see if it goes away.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

If it's cold out, it's actually better to just let your bike sit than to start it up for a bit each week. Unless you get the bike hot enough that water boils off the interior of the collector and the muffler (and you really need to go ride it for a good 15-20 minutes to do this), all the moisture in the exhaust (water is a by-product of combustion) condenses inside the collector and especially the muffler. It then sits in there and rusts your exhaust from the inside out.

If you're worried about the battery, buy a Battery Tender and just leave it plugged in all the time.

I didn't know that. Usually when I crank it, I will run it up to temperature and stuff before I turn it off. I guess I will stop doing that to save my exhaust system. Thanks for the info.

Like WingAdmin said, but also add gas stabilizer to your fuel and top up the tank so that if will not collect condensation in the fuel.
