Ah yes, the loose baffle rattle. That's the trouble with long-distance problem
guessing. All we have to go on is a descrirption.
I could
supply an audio file (MP3) of a good 700s running but what is needed is audio files from bikes
with noises. Thankfully I don't have any of those. Maybe better descriptions would help.
I wonder what would help expedite the process of resolving issues more; better
descriptions from owners or a primer on diagnosis. How many have cleaned carbs when it was ignition ?
How many have bought ignition parts to solve carb problems
? And, worst of all, how many motor repairs performed to find muffler rattles ? Let's all try to
figure out a way to prevent needless money spent and time wasted. I don't type very well but I have found that
a good description helps get my problems solved. Brevity isn't always the best
thing.

my 86 nh 700sc sounds like it has a lose cam chain but if i put my foot on
the muffler it stops. make sure your muffler is not causing the noise.

OK I'll try the seafoam additive if you reccomend it. Any ideas as to
why it goes away when bike is tilted to the left?.
Thanks again,
