'92 EVO primary noise, VERY WEIRD HELP!!
Hi Guys, i am very new to this forum, this is my first EVO big twin bike, it's a 1992 Heritage with 32kms or 19k miles and i am the second owner, and i am becoming annoyed by a sound in my primary.Took it to the dealer and they replaced the tranny front belt sprocket as the nut came loose and damaged the splines on the sprocket, but was told the mainshaft and all other components seemed ok.
I pick up the bike and my noise is still there, what is happening is when i lean the bike to the right i hear something like a vibrate rattly noise primary side , and when i lean the bike to the left same noise, hold bike vertical and no noise, very weird, when driving the bike all seems fine .But sure sounds like its coming from the clutch hub area. bike drives fine and shifts fine all seems OK.
Dealer tells me clutch is good as well as compensator nut is fine and so is the chain and adjuster. Could it be the Hub bearing going or gone, dealer also said it looked fine as well.
I am totally lost as what is going on.I really need help with this, as i just bought the bike and are very stressed that it may be expensive to repair.

Welcome.
I can't help you with your current situation, but remember when we first got our old Harley. An old time Harley rider that was a coworker gave me some good advice, he said "It's a Harley, (for Christ's sake) it supposed to have problems" I know our 1990 Ultra always has something wrong, but we have it going on 6 years now, put on about 56 thousand miles during that time ( bike has 120+ thousand miles) and the closest we got to being stranded was one time a little, inexpensive return spring in the transmission broke and I had trouble shifting it.
In as much this Harley is very new to you and a reputable mechanic checked out the bike, I would try to relax a little and wait to see. Some times vibrations and noises come from unusual places, exhaust may be hitting, worn tires, some accessory has a loose bolt etc. Take some time cleaning your bike, as you get moving around, feeling different things keep an eye out for anything that may be hitting, rubbing or loose etc. When you clean your tires look at the tread, etc. Buy a service manual, get to know your bike, but I warn you it does become addictive. It is also possible that you are being a little too sensitive.

Good advice from pajoe. Around the time our bikes were built Harley was a very different company to the Harley of today, making bikes in far smaller numbers. This in turn makes them more individual, because they were not being built using the mass-produced techniques they use now.
So look upon your bike as much more of an individual, with its own idiosyncracies! Ride and enjoy it, but keep an ear cocked....

Mine has a yum yum siren sound between 60 and 65 that is worse when going around a curve and leaning to the left or right. Sounds like the belt to me, but not sure. I guess it could be the back tire, although it does not appear to be rubbing on anything. It only happens once in a while. I will change something one of these days and it will either get better or worse. I am about due for a new rear tire anyway.

I think a cupped tire or one that needs balancing can cause vibration. I read some of the newest Harleys were having a problem with a batch of Dunlop WWW tires, and the dealers would replace them if the owner complained about vibration. Naturally this was only for new bikes under warranty. A coworker with a 2010 Harley claimed a friend had a Dunlop WWW the dealer could not balance because it was so far off, but I don't know anything of the details, some times the stories are not very accurate. I am using Dyna beads to balance my new rear tire, seems to be working so far.

Yes pajoe; That could be what my noise is as my rear tire is a Dunlop 404, and is cupped a little. It is also about due to be replaced from wear. Maybe when I replace it the noise will go away. Thanks for the heads up.

At the time I couldn't figure out where the problem was coming from...I just heard this intermittent clicking and tapping, sometimes like metal rubbing. I took it to an HD shop and they tore into it, replaced pushrods, cam, lifters and anything else they might be able to explain it...they gave it back to me and the noise was still there. I finally tracked down an ol'wrench that worked on my bike a in the past who knew the evo quite well but changed shops. He dug in and discovered the dislodged magnet, replaced the stator, and the mystery was solved.
I've never heard of anyone else having that problem. This was on one of the old 22 amp systems but newer models have a different rotor part number so maybe they are not susceptible to getting a loose magnet ... it is worth keeping in mind as a long shot.
Of course they may be onto something if they suspect the cam bearing...that has been talked about alot in the forums here due to the inferior INA bearing that is used. There was a recent thread here where someone bought a bike recently that was making an odd noise...it ended up being the cam bearing giving out...unfortunately it damaged his cam and some other components before he was able to discover the cause of the noise.

got my first evo BT two years ago. Paid two people to work on it and then said F-it. The manual is $30-$50 depending on where you get it, and getting into the primary is a piece of cake.
Knowing what to look for might be a different story, but...you'll learn. They're very simple machines for the most part and pretty much anything can be done with the manual and right tools.
Getting the primary off to give it a look requires nothing but an allen wrench, a couple gaskets, and some primary fluid.
