I'm still misunderstanding something here. There is no way an engine with broken connecting rods will run. We must be talking about something else being broken that isn't usually referred to as rods.
Ditto that's a new one.I'm still misunderstanding something here. There is no way an engine with broken connecting rods will run. We must be talking about something else being broken that isn't usually referred to as rods.
I think that makes sense for a Harley as I believe they still use multipiece pressed together crankshafts? Older four cylinder Japanese bikes also had build up cranks. This was because they used lower con rod end and main rolling element bearings, which you can't split like plain bearings. Split plain bearings allow the use of one-piece forged/cast crankshafts. This is the design the for the Super Tenere (and most four stoke bikes today), so welding it's crank would not have the same advantage.Why I had the crank on my road king trued and welded
The RT used more when new, than it did with 60K miles. And, even at 60K, it used more than any Japanese bike. The KLR didn't use any, as long as you kept it under 75mph. Above that, it got real thirsty.. . . . An fyi, there are several models and brands out there where it's "normal" to consume motor oil. Please check your levels once or twice a change cycle.
And here I've been living in blissful ignorance assuming that my days of checking oil level in modern cars were over. I legitimately thought newer engines weren't as susceptible to that anymore... goes to show you not to believe what they tell you at the dealership.I've got a Honda Pilot that comes in every 5,000 miles with less than a quart in the pan. The customer absolutely refuses to check it. I've got a Subaru Forester four cylinder that does the same. The burned up motor I mentioned was one of the small Chevy motors.
Never knew that existed!I get an email every month that tells me my wife's RAV4 oil level is correct, along with confirmation that the "smart key" battery is good.
You're correct, there's no way to tell until you've had the vehicle long enough to get a feel. That being said, I can't remember the last time that I had to add oil between changes. And, nowadays, the oil comes out much cleaner than "back in the day".I think this is a case by case issue related to engine design and other factors. Some engines are just more likely to consume oil than others. It could also be an assembly or manufacturing issue. If an owner neglects oil changes, uses a substandard air filter and lives in a dusty climate, or runs the engine too hard before it's allowed at least a couple thousand miles to break in, any engine can end up burning oil, sometimes at fairly low mileage.
Actually an engine will still run with a broken rod. My KZ 750 spit out a rod on the freeway and still ran on three cylinders until I pulled into the station and shut it off. Even when I got it home it started right up. I was scratching my head at that one. I rode with the rod knock for hundreds of miles before it finally let go.There is no way an engine with broken connecting rods will run
A twin is unlikely depending on what failed, but if the rod bearing failed and the rod is intact it could possibly. Full breakage unlikely to run though.OK. A twin won't run with broken connecting rods.
