    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Exhaust sounds

At one point, I had my mixture set a little on the rich side (I think). The exhaust would make very pleasant popping and burbling sounds when decelerating. Is this harmful? After resetting the mixture screws for best idle, the sounds are gone. I miss them...

I'm a little late on this, but I have to say, you like those sounds??? ;-)

I always wince and feel slightly embarrassed that my bike isn't running 100% perfectly. But then again I'm pretty anal. ;-)

That's at least for the popping. I do like the smooth rolling grumble a well-tuned engine makes when engine braking.

Yes. I DO like those sounds. Of course, I've always been a half bubble or so off center. I wonder if the sound of the exhaust during decelleration is really a good indicator of the proper tuning of an engine?
 
Naw, mine does it too occasionally. I'm sure it's nuthin'. Hey I just don't like the pops, the rest is cool. ;-)

cheers guys thanks for the help. I have tried to it it up the stand but must be an Irish weakling. I will keep at it.

Just keep trying. I'm 150 lbs and I can do it no problem. I wrestled with it at first. Almost dropped the bike a couple of times. Crushed my left toe (sandle :oops: ). I'm a stubborn **** though.

Left hand on handle bar. Right on grab bar. Right foot on lever. balance the bike so that the center sand is touching the ground at both points (maximizes mechanical advantage by allowing you to pull straight up and keeps the bike from falling over). Put all your weight on the lever with your foot and pull up/push down smoothly. USE YOUR LEG; it has more power than both your arms.
 
BTW a "popping" from the exhaust, more often indicates an exhaust leak at one of the joints.

That's possible in my case. The gaskets haven't been changed since I've owned the bike. The header has been on and off quite a few times.
 
mine came a 4 into1 exhaust which i removed and took off as much rust as possible(its back, i didnt do avery good job, i am thinking of getting it sandblasted and black heat piant). the thing is there were no gaskets between the 4 pipes and the engine am i missing something???
 
are they available from most bike shops. are they rubber cock papaer aer what as i have no idea

Cheers

OEM is still available from Suzuki, or other parts sites. I believe they are Aluminum. I bought four earlier this year and replaced them as soon as I pulled the exhaust.

Patrick has just called past to buy my retired 850 as a spares bike. Sad to see the end of my GS years, but glad to see it go to a good home.

Anyway, there's something very wrong with his centre stand. It literally takes 2 to lift the bike onto it. Problem certainly not caused by Irish feebleness. A stand swap should sort things out.

Exhaust popping:
1. Leaking inlet manifold.
2. Leaking exhaust manifold.
3. Blocked/ dirty jets in a carb or carbies.
4. Incorrect (lean) jetting.
5. Missing or holed air filter.
6. Free-breathing after-market exhaust.

So, except for #6, it's not OK... PLEASE FIX:!: ... unless you like burnt valves, cracking aluminium around the valve seats, and then perhaps valve seats dropping out, etc.
 
It was good to meet up with "Tool" this week. I have purchased his 850 as spares as he says in his posting:-D . I will be picking it up next week and a few bits and pieces will be changed over. Its going to be fun. BTW now got the gaskets for the heads. cheers.
 
A little late but I am advised if your bike has CRABS stop parking in the harley area.
