Valve Adjustments?

Postby portugeezer » Sat Oct 13, 2012 10:25 am



I finally broke down and put plates and insurance on the Aspincade that was supposed to be my winter project. I got to see how it acts at all different speeds, going uphill etc. At lower speeds and I mean under 40mph not engine rpm's it runs great aside from a bit of chatter on takeoff. At higher speeds I seem to have a bit less power and some engine vibration. Does this sound like I need to adjust my valves? I had an old Kawi act similar oonce and it turned out to be the weights and springs in the timing advance. I oiled them and it was fixed! Is that something I should be looking for?

The chatter at takeoff could be carb synch..But on ours I just learned that the 4 cylinder wings like higher RPMs even at launch...My 1500 (6 cylinder) is different with a hydraulic clutch and very low RPMs..So I turned the idle up to 1000 and synched the carbs it was better..Then I adjusted the valves and it was better a bit more...now I am running Seafoam in the oil to help clean out the clutch plates and the engine internals..(to be determined)...

Little adjustments = little advancement..but do several adjustments = NICE... 8-)

I would adjust the valves-it isnt that hard-and it can make a world of difference. Regards, Johnyy

Thanks Johnny I think I will. I suppose I should do the valve adjustment on my GL1000 as well. I did discover something this morning. When you start the bike cold it fires right up. I felt the exhaust on 1 and 3 they warmed up very quicly as did 4 but 2 warmed very slowly. I'm an old musician and I am hearing impared but I could hear a barely audible (to me) clicking that sounded like an arching plug wire coming from somewhere under the false tank. I'm pretty sure cylinder 2 is only getting intermittent spark. On the plus side I rode 120 miles yesterday. I like the refinements on the 83 compared to my 76. The most noticeable thing is the gearing. You are pretty much in 5th gear on a 1000 by 45mph and I'm always trying to shift into 6th gear that dosen't exist. I like the self cancelling signals a cool thing for a deaf guy and the dummy gear indicator. The bike is more nimble and lower to the ground too! I also find it is easier to push around in parking lots and such!

Now you are making me want to get an 83! I have actually been thinking of finding another "basket case" an 83 would be fun to rebuild. Here I go again :D . Regards, Johnyy

But then again-did you check the timing advance unit? on my 1980 1100 you just unplug the line to the carb and suck on it to see if it advances the engine while its running. Just a thought. Regards, Johnyy
