Hi all,

I was curious about the sounds of the c50. Mine is an 06 with about 12000 km or 7000 miles. The oil is changed regularly and had the valves adjusted in January/07. No mods to the engine but have put on an engine guard and quick remove saddle bags. It has always sounded a little clanky on the right side (exhaust side) but not obnoxious. It is not as quiet as the shadows I have heard. I do find lately though that when I get going in 3rd at around 62kmh or 43mph just before I change to 4th there is a kind of buzzy ticking noise from the exhaust end, almsot like there is a reed buzzing. It seems to be more noticeable when it is warm out. Should I be concerned or does anyone else get this from time to time?

Boston:???: thanks in advance for some input
 
I get the same thing on my c90t. especially when it starts up, kind of a thwacking sound on the exhaust, almost sounds like a valve hammering. the 90 is supposed to have self adjusting valve. I also get the buzzing sound when riding too. Seems to be coming from the left side though
 
It is normal internal engine noise. Just has my C50 in for service and asked about it. The tech told me it is just normal internal noise. Suzuki makes noisey bikes lol.
 
Yes, I've heard and read on this site that the engine is mechanically noisy. While the Shadow goes "phut-phut-phut" the boulevard goes "twack-twack-twack". I tried to do the valves myself at the start of the year and left them too loose so paid to have my "fixen" fixed. It sure gave me an appreciation of the trouble to get at the valves. Thanks for the feedback.
 
That would be either; hydraulic LASH adjusters, or lifters, valves can't self adjust on their own, they are one piece. The part that makes contact with the lifter has to do the adjusting...
 
My C50T has a low click when warmed up, but is not as loud as it was with the break in oil in it. IT "tack-tack"s when first started up, or going up hills, but when cruising, it's a nice low click-click...

Your GAS also makes a difference. I notice more noise with low octane as well.
 
I took a long trip this Saturday, over 300 miles. The engine is officially broken in, and is as quiet as ever! Just a little bit of clicking now, no where near as loud as it was.
 
Well, I went to the dealer here on the island. You'll never guess what was making the noise. It was the licence plate buzzing at a certain rev. Just had to move it a bit and it was fine. No more weird buzz. The best way to describe it is at certain revs it sounded like a bicycle with a playing card in the wheel, such as we used to do as kids. I'm glad that is off my mind.

cheers, boston
 
I had the end of a metal tye wrap under the gas tank buzzing at 80 MPH. I just moved the loose tail end up away from the tank and the noise went away. I also did my own valves and set them, the exhast at the .008 and they make noise. I might have it PROFESINALLY done after next weeks vacation.
