Quick Tips to Properly Break-In Your Engine and Motorcycle

  Quick Tips to Properly Break-In Your Engine and Motorcycle Do you break in your bike easy? Here's a tip to properly breaking in your ride We occasionally hear from owners of big twins that their bikes use too much oil, smoke or have other problems even though mileage is fairly low. When we ask about break-in procedure we inevitably hear that the owner “broke it in real easy.” In other words, they never did break it in. Because big twins make such good power at the lower portions of their powerbands, it’s possible to get perfectly acceptable performance out of them without running them hard. The problem is that unless your run them hard once in a while, you don’t put enough pressure on the piston rings so they seat fully, which can lead to oil-control problems and varnish on cylinder walls. Breaking in a new motorcycle involves lots of components from brake pads to valve seats to tires. There is always the possibility that something will crack or warp during break-in, so those initial miles should be ridden with some caution and an eye and ear alert for problems like leaks or unwanted noises. The heating and cooling process is also part of break-in; parts expand and contract and adjust to each other. By the time you have ridden 100 miles with no signs of problems, your engine should have gone through a few heat cycles, the brake linings should be adapting to their friction surfaces and the tires should be scuffed in enough to deliver good traction.

The color of your exhaust smoke holds the answer.

Q: My Suzuki Intruder is an occasional smoker. Most of the time it’s fine, but every once in a while I’ll glance back and it’ll look like I’m James Bond and I just pressed the smoke-screen button. It seems like it happens more when the bike is hot, but it doesn’t seem to matter if I’m accelerating or decelerating, which I vaguely remember a mechanic friend of mine saying would tell me something about the pistons or valves being the problem.

The bike is older, fully uncorked with a pipe, high-flow air filter, and jet kit. I ride it hard and it has about 60,000 miles on it, so I’m wondering if a valve job might be in order. Think that’ll fix my bike’s smoking habit? - Jeff Moore via email

A: You didn’t say what color the smoke is, which can provide an important clue to what’s wrong. Black or gray smoke often indicates a clogged air filter or too-rich jetting; you’d see a reduction in mileage and power. Blue smoke is usually caused by oil getting past the piston rings during acceleration or by the valve-guide seals on decel, eventually resulting in low oil level in the crankcase. White smoke means coolant is finding its way into the combustion chamber, which can cause overheating. A bad head gasket is probably the culprit.

To narrow down the problem do a leakdown test; you’ll need a special tool for this. Warm up the engine then put the piston at top dead center on the compression stroke so both valves are closed. Pump air into the cylinder through the spark-plug hole and measure the leakdown with the attached gauge. If the leakage is higher than normal according to the shop manual, listen for a hissing sound at the end of the exhaust pipe caused by a leaking exhaust valve; hissing inside the airbox means it’s an intake valve. Worn piston rings can be heard through the oil-filler hole in the engine or oil tank, and a bad head gasket sometimes bubbles the coolant. While you’re at it check the spark plugs to make sure the engine isn’t running so lean it’s overheating and damaging the rings or valves.

The Freakish 3-Wheel Yamaha Niken Sportbike Looks Unbelievable .
Yamaha brought something interesting for the Tokyo Motor Show, and it’s a bizarro three-wheeler sportbike. Surely it’s too early for it to be some sort of elaborate April Fool’s joke, right? The bike is called the Yamaha Niken, and it looks like it has a conventional rear end and Yamaha’s liquid-cooled inline three-cylinder engine. But from there it sprouts two sets of forks and two wheels, giving it the look of some kind future chariot.Yamaha says the benefit of the Leaning Multi-Wheeler is that it “reduces the effects of changing ride environments and to deliver a high feeling of stability when cornering.
