Once and for all, Truth about Timing Chain Failure

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

Cheap Ford Pinto Motor went 150,000 miles

I drove my 1975 ford pinto 150,000 miles without any inside engine work changing the oil every 2,000 miles. Did have to replace the timing belt every 60,000 miles but that was pretty easy as it wasn't inside the engine.

I don't think you are going to get many responses from people who have put over 100,000 miles on their C50s- there are only a few owners on this site with that many miles on their bikes, and they have all replaced their entire engines at least one time, sometimes multiple times.

You are going to get a lot of responses with cam chain problems in the 40,000-50,000 mile range. Myself included- cam chains starting to have problems with 45,200 on my meticulously maintained 2006.

The C50 is an inexpensive bike, with a very small engine for a bike as physically large as it is, and steeply geared to make it work- my C50 is actually slightly longer than my Electra Glide, but the Harley has an engine more than twice as large. So it stands to reason that the bike with the 800cc engine that cost $6,699 brand new is simply not going to last as long as the $18,999 bike with the 1700cc engine and six speed overdrive transmission. Cars are the same way- no one would expect a $11,000 Chevy Aveo to last as long as a $35,000 Acura RDX.

A C50 should give you 40,000-50,000 good miles. As the average owner of a small Japanese cruiser only puts 3,000-5,000 miles a year on their bike, this is considered to be a more than acceptable life span, and is about what you would get out of similarly priced and sized models. If you want a bike that will last 100,000 trouble-free miles, get something much larger, like a Kawasaki 1500, a Honda Goldwing, a Kawasaki Concours, anything from BMW, or anything from Harley that is not a Sportster.
05, 06 years.You may be on to something.

Thanks, good eye, you may be on to something here.
You know it seems like from what ive read here on the forum that the 05,06 model years come up more for premature engine failure. What say everyone?
C 50 engine, is it the same as in the first Valise's

Do you know if the engine is the same as in the Volusia's. They have been around for a long time
Doubt it. Those are the oldest model C50's at this point with the most mileage. IMHO, the individual riding characteristics and engine maintenance has the most to do with how long these engines will last.
How many miles on your 2007 when it Self Destructed ?

How many miles on your 2007 when it Self Destructed ?

There is no rhyme or reason as to why some bikes are dead-on reliable and others expire prematurely. I used to be in the 'it has to be a maintenance/riding style' camp. I treated my C50 like a baby. Did every maintenance item to the letter and used only top-shelf products. It didn't matter as it started burning oil and eventually self-destructed in just 4 short years. Others have nearly twice the miles I got and have never even cracked the engine to inspect their valves. It makes no sense..... So I can't tell you how your bike is going to fare long term. It all depends on what mood fate is in at the moment....
Looks like engine worn out but Timing Chain OK?

Looks like your engine wore out but Timing Chain OK? I change oil every 2000 miles, check valves every 5,000. Lubed drive shaft at 12,5000. Bike has 13,000 miles on it now so I will probably sell it when clock reaches 30,000 miles. Gives me 17,000 more miles and hopefully new owner can get plenty of miles before needing overhaul.

It was a 2005. It had 38,000 miles on it. The engine started using some oil ~ 20k miles. It was never a lot and I just kept it topped off. Then out of the blue, it consumed more than a quart in 500 miles. It was so bad, it was belching blue smoke out of my exhaust when I got on the throttle. I only used synthetic oil, changed at 3500 mile intervals, a new filter every other change. I even went as far as to clean out the oil sump, screen and filter every other oil change. Adjusted the valves to the middle of spec every 7500 miles. Ran a DJ drive to reduce my engine rpm and had a fuel processor installed to keep everything happy. I could not have done more to take care of the bike than what I did. I was religious about the oil and checked it EVERY time I went for a ride. It was really disappointing, because I was absolutely convinced that the cause for the early engine failure was a lack of maintenance. I was wrong.
57 k without cam chain problem, also 65 k before cam chain problem

This is great news; Facebook friends report these good facts about our C 50 motors:moneyeyes:

Lynda Desousa-Hudlin, I have 57,000 on my 2007 C50T---so far i have had no problems at all with anything!! And yes, that is not 100,000, but my thought is---if you still love the bike, and want to keep it, then you have to do the servicing!!!! I am planning on getting a new bike before I reach the 100,000 point, so for me I won't be doing the timing chain issue.

Sean Revels I have a 2005 C50 with 70,000 miles. I had to swap timing chain at about 65,000 (back in January of this year).
150 on timing chain

My Chevy cavalier went past 150,000 miles with timing chain noise or replacement

I did not realize we owned the MC equivilant of a Chevy Cavalier? Lol... Hasn't that car been discontinued? Along with the Pinto, Vega
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.

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


Thanks, needed a good laugh today...
c 50 motors have hi-vo link plate cam chains . Are master links available for these types of chains
