Question I am the proud owner of a 1989 Suzuki GS500E. I just recently purchased this bike. I am noticing a ticking like noise, in the motor, that comes and goes. Since it is an intermittent noise, I was curious as to what it might be. I believe that I should be concerned about it but I can't really afford to do anything about it right now. Is there any additives that might quiet it down? What can I possibly do short of having the motor overhauled? Speaking of an overhaul, what should the average price be to have that done on my bike?
AnswerHi Chris,
I suspect the noise is caused by slightly excessive valve clearances. The noise is most common when the engine is cold. Nosie usually goes away as engine temperature rises and metal expands, tighening valve clearances a tad.
If this is the source of the noise, not to worry about engine damage. Consider checking valve clearances and adjust if necessary. Little or zero valve clearance causes engine damages. Slightly excessive clearances causes tapping sounds. This is not a problem if valves are checked at recommended maintenance intervals.
The noise may be something else, I would need to hear the noise to confirm.
There are no additives to make the noise quiet. Avoid adding additives to the engine oil. They may damage the clutch plates or cause oil seal damage.
The only gasoline additives I recommend are "Sea Foam" and "Marvel's Mystery Oil" for the prevention of carburetor gas varnishing. Follow label instructions to the letter if these products are used.
The engine does not need overhauled. More likely, the valve clearances need checked and adjusted. A tune-up may cost about $200. Inquire with your local Suzuki dealer about the cost of their "tune-up" or valve clearance adjustment.
