I was wondering what could cause my 82 aspencade to chatter when taking off in 1st. If I rave up the engine and the let the clutch out it seems it reduce the chatter also traveling around 30 MPH and in 4th gear it chatters unless I down shift to 3rd were the RPM's are of course higher the no chatter. Any idea's?:?

Thanks,

got to have your revs up starting off also as speed decreases need to lower gear to keep rpms up, your moving a whole lotta bike and you to.:action:

Thanks thats kind of what I thought, but I wanted to be sure I was thinking right and not something I needed to address.

Just a thought or two...there must be a little freeplay (free lever movement that does not disengage the clutch, ~1/4") in the clutch lever when it is all the way out.

If you have that freeplay, and it still chatters, you might want to try a Seafoam treatment. Some folks seem to believe in that MMO (Marvel Mystery Oil). Either way, you dump it in the crankcase for the purpose of cleaning outgooey buildup. :waving:

Thanks, I use Castrol GTX 10w40 motor oil. I will try adding the sea foam to it and see if that helps the chattering on low RPM's

Mine does the same thing.

You need to keep the RPM's up a bit.
:coollep:Have to agree with Jim and Lee on this one,

Mine has done it since I bought it 10 yrs. ago, a few more rr"s in low gear takes care of it, and when I'm down to 40-45 I'm in 3rd or 4th gear. Just my .02

You might be running a little rich. When my bike was running rich it would chatter in first gear and lug at 2000-3000 rpm. Check if you have any black smoke coming out of your pipes. Also it can't hurt to make sure your carbs are synced properly. Of course I could be wrong but kind of sounds like my problem before. Hope everything turns out great!

When I first started to ride a wing, I found I had to give her a good amount of gas to aviod what I called the "Death Rattle". It improved greatly when I synched my carbs. I still get it if I get caught going too slow in too high a gear.

Now that I have my carbs synched and have given them several cleanouts I find I can take off at about 1500rpm without the death rattle. Prior to getting the carbs right 2000rpm plus was required.

I agree, Its normal. You just have to give her a few more RPM's at takeoff and be aware of your tach when you are riding up a steeper grade. This bike needs to be downshifted a lot to run optimally especially if you ride 2 up. As far as the carb synching stuff, if it runs good, just ride it. Try some seafoam though, put half a can into a full tank. It will make a difference.

My 82 wing does the same thing if I dont give it enough gas during take off. I think its normal but it does sound terrible. It's a big bike.
