Once and for all, Truth about Timing Chain Failure

25816 Views 76 Replies 29 Participants Last post by  jasonpinson143
There has been a lot of talk about timing chain failure on the C 50 Boulevard engine. I find it hard to believe Suzuki built a motor and continues to build the same motor with a timing chain weakness considering todays advances in motor technology. Any well designed motor should be able to go 100,000 miles with proper maintenance today. So here is the question. has anyone ridden their C 50 motorcycle 100,000 and did you have to replace the timing chains and tensioners. And if you did have the Timing chain problem, how many miles were on your motorcycle. Please include the year so we can look for problem years.
Thank you for participating.
I just bought a 2007 C 50 Boulevard with 13,000 miles on the clock and want to know whether I can plan on riding it another 87,000 miles without a timing chain failure or whether I should sell it at 25,000 for something better designed. Thanks and hopefully we can get to the bottom of this timing chain issue

A motorcycle engine?!?!?!
100K miles?!?!?!

BAHAHAHAHAHAHAHA!

Thanks, needed a good laugh today...
high mileage motorcycle motors

My son got 120,000 + miles from his 1998 Honda VFR, only replacing the clutch plates a couple of times. He did use synthetic motor oil and changed the oil every 3000 miles.

Rotella synthetic almost since the beginning and every 3,000+/-.

Why's that sound so ludicrous?
I've had several ancient Yami's well past that mark, a couple Kawi's, an old Indian enduro, and even a couple suzi's that outlasted 100k before having issues. None babied, most fed vile cheap oil and fuel, all abused (Cept for "Lucky Lucy").

Hell, "Lucky Lucy" (my 04 VL800) is showin 168,XXX with all but the first (had 6,600 on it when I bought it and timing failed at 12,xxx) 6,000 miles of that trouble free in every way. Only repairs: brake pads, a new rotor, new plugs, wheels and tires. I've more time and money sunk into mods and goodies than maintenance. Either I am and have been extremely lucky or 100k without anything major going wrong really isn't all that big a deal for a bike engine when properly maintained.
So many variables.

If I have this right, I could drop the engine about 3" to give me room at the top, remove the covers on top and on right side, then feed the chain through. Worst case, pull the camshafts off to get some room. Is that about right?
c 50 motors have hi-vo link plate cam chains . Are master links available for these types of chains

Goldwing owners have a 100K mile club and BMW has (used to anyway) a 200K club.

I personally have known a few owners over the years, of various bikes, that have gone 100K without an engine rebuild. Most recently an owner of a VTX1800 with over 120K.

I agree that on an average it doesn't happen with most bikes (for various reasons), but it is not that unusual.

You do realize your pointing out bikes that have displacements that are more than twice the C50?. The C50 is working hard to keep up and higher rpm's. Cost of the bike eventually does play into it. $7k+ plus for the C50 versus $12-15k that will come with more casting, more displacement, less rpm's, bigger bottom end, adjustable cam chain, etc, etc. in my opinion, the C50's were not designed to 100k miles. Will they do it? with the right care, proper maintenance, and pure luck of metallurgical wear, might do it. There are case histories yes and no. The original intent was to introduce the rider to a medium cruiser and move up, trade up, class up within a reasonable mileage range. IMHO!!!

No misunderstanding here. Just replying to your post "A motorcycle engine?!?!?!

Have a good day.

I have 52K on an '02 with no problems other than a clutch cable replacement.
Also, I am still on the original battery.

Yes, but aren't zombies undead?
That's what he's saying. This thread was dead and buried until someone came along and dug it up.
Well, excuse me... I'll put my shovel away. :)

One of my buddies has a C50 with over 60,000 miles, never had timing chain trouble.

I hear mine now at 77k miles. Ride it till it stops. I guess what I hear is the adjuster not necessarily the chain?
What do it sound like?
Kinda clangy or rattle like lower down below the jugs, rear half of the engine, right side. I hear it after revving it and the engine is throttling down in Nuetral while standing next to the bike. The slack seems to rattle. I've got a spare low mileage motor in the garage when I need it. Acquired a parts bike a year or so ago.
65K kms so far and counting. M50 2006 model. Probably will get to 100k Kms but the rattle is there since ~15K kms. in my opinion the problem is that it's difficult to replace them not the fact that timing chains and tensioners may get damaged early. That can happen and depends on many things.
Hope you make it to 100000 km or 60,000 miles? I recommended the other day that when it gets to 60,000 miles sell it or trade it.
