1977 Gl1000 noise

Postby 1977gl » Sun Mar 22, 2015 4:11 pm



the engine makes some noise until it warms up, like a clunk sound almost, I can put the clutch in and it will go away , it also goes away once the motor warms up eventually, i am kind of worried and a wee bit ticked off cause i just bought the bike and don't have the greatest income to fix it, so i hope its nothing serious but it probably is with my luck

Without hearing the noise can't say for sure. When you start it are you using the choke? When the choke is pulled out fully does the RPM increase to around 2500 to 3000 rpm. It should and then decrease as the choke is pushed in. I don't see a problem if the engine smooths out after warming up. These old girls are cold natured and will "buck" without proper choking and fast idle speed.

Nice bike! Probably not a problem. Oldwings are klunkady. (Hey, I made a word!) Carbs might need tweaking-they are sensitive.
My exercise bike is a goldwing.

The fact that it goes away when you pull the clutch in (which disconnects the engine from the transmission) says it is either in the transmission, or more likely, the HYVO chain connecting the two. The fact that it also goes away when it warms up makes me not worry that it is something seriously mechanical. What kind of oil are you running?

Not sure what oil it is, just got it and been running it up and around the neighborhood until i get it all legal, I am changing it to honda brand regular oil I got a stock oil filter and a fram filter the guy gave me with a box of other extras he give me, it does go away when it gets warm and ya when you fully engage the choke it goes up to 2500-3000 rpm when it warms up i slowly reduce the choke, i really love the bike i truly do! I just think it needs a good tune up and a fresh carb sync

You're very likely right on the carb sync. When the carbs are unbalanced, they cause a vibration in the primary chain that sounds like gravel in your engine at low engine RPM.

ya i am quite sure it is the sync in the carbs, it gets lousy mileage and it likes to try to kill (about 4 times so far) when downshifting
