Miles to wear out a C10?
« on: May 04, 2018, 12:26:28 am »
How many miles will a C10 go before it needs an engine overhaul? 

Just curious
Remember, much of what you see on-line is wrong or misguided, your task is to filter that out!

Depends on what you consider an overhaul? If you mean replacing bearing surfaces, cylinder rings, etc., many C10s are on the road with almost 300K miles on the original engine. At that point I think a few water pumps and other things have been changed, I am sure those owners will chime in lol.

  118,000 miles!!  It is better than when I bought it new. A whole lot of members made real improvements over the yrs. and I think I have most of them.

   Changed the water pump once. Started leaking out the weep hole so figured it was time for a new water pump. probably around 80,000 miles. Replaced clutch star spring. And a whole lot of Murphs and SiSF's  goodies.  :) :)

Basically nothing major failed in all these years.

I had to replace my wp at only 15k miles.

Changed my water pump at 165 as preventative maintenance. The old one was perfect. Other stuff, driveshaft, alternator, 2 sets of front brake discs, SiSF Torque camshafts. That was pretty much it for 234xxx miles. Carb work including one refresh and SiSF's magic and one set of less used carbbies.
Yeah, if you want true ram air tuning, you better be willing to ram some air! (SiSF)

More bikes die from not being ridden and neglect than from many miles ridden with proper maintenance.  I'm working on my buddy to bring his bike over so we can do things like change his 5 or 6 year old brake fluid! :-\ :-\  That's a bike that also needs to be ridden more! :motonoises: :motonoises:

Me too, mine failed at low miles, under 20K I think. Must just be a fluke.

I hate to rain on the parade here....
I bought my '98 brand new and thought I took good care of it; 3K mile oil changes, 6K mile valve clearance adjustments, stored inside and ridden between 3,000 to 10,000 miles per year. Despite that #2 cylinder lost good compression at approximately 80,000 miles. Still rideable now at 100+  thousand miles but it's not right. This is not a hydrolock motor, I'm not sure what happened internally.
I bought a '04 Concours last November with only 11K miles - the difference between the two bikes is stark. I'll keep the '98 in one piece as a spare bike but soon it will become a parts bike.

I have a low mileage valve head if you want to freshen up that motor. I doubt it is piston ring related, maybe carbon'd valves or maybe just worn out valve head. Of course there is a stark difference between your two bikes, one has low compression. I would wager that a bike with 100K or 200K to run as nicely as a sub-80K mile bike, if everything is set up right. Also tuning makes a big difference in enjoyment over stock, by the time alot of the COG bikes make it past the 100K mark, they are running most of the goodies.

Also, your inexpensive Japenese motorcycle made it to over 100K miles, and certainly isn't dead, that is impressive. The fact that folks around here have 200K, almost 300K, just goes to show the potential.

My first Concours was a lemon from Nevada, it looked nice but I didn't notice the broken speedo cable until after purchase. The mileage was 60K+, but it could have been anything. After I gave her a light hydrolock, maybe not the first, the engine eventually developed a knock. The bike's wiring was also all spliced and hacked up, the whole bike was a mess. She had a hard life..

Bought my new Connie with 18K, she has almost 60K 4 years later. I expect a very long life from this engine, I consider any problems
an anomaly.

VTConnie - I'm not sure what happened to the '98 to give it low compression. SISF found the carbs from that bike to be exceptionally worn and had to replace parts which at that time made my carbs the most expensive he ever did. There was a small crack in the air box which might have been responsible for the carb wear but that would have caused uniform low compression (if dirt found its way past the air filter).
These motors are bullet proof and long lasting and I'm content that 100K miles was a lot more than I had expected from any motorcycle. Thanks for the offer of the head - I'm happy to use the '98 as a parts bike eventually.
The Concours is a great bike - everything I want. I've owned three so far; crossing the US twice and five tours in Mexico. This newer 2004 may outlast me - although we had a visitor on a Harley this past weekend who was 85 and still riding.

On mine with a boroscope I could see the carbon buildup on the some of the valves.
That is most likely your compression loss.  I had to flog the crap out the engine to clear the carbon deposits and  make it run right :motonoises: :motonoises:

I believe around 250K is the average on a C10.

Most any modern well engineered engine with decent maintenance, should be expected to last at least that.
