    Default How to Breakin (runing) the new motorcycle Engine

    Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power

    On the Street:
    Warm the engine up completely:
    Because of the wind resistance, you don't need to use higher gears like you would on a dyno machine. The main thing is to load the engine by opening the throttle hard in 2nd, 3rd and 4th gear.

    Realistically, you won't be able to do full throttle runs even in 2nd gear on most bikes without exceeding 65 mph / 104 kph. The best method is to alternate between short bursts of hard acceleration and deceleration. You don't have to go over 65 mph / 104 kph to properly load the rings. Also, make sure that you're not being followed by another bike or car when you decelerate, most drivers won't expect that you'll suddenly slow down, and we don't want
    anyone to get hit from behind !!

    The biggest problem with breaking your engine in on the street (besides police) is if you ride the bike on the freeway (too little throttle = not enough pressure on the rings) or if you get stuck in slow city traffic. For the first 200 miles or so, get out into the country where you can vary the speed more
    and run it through the gears !

    Be Safe On The Street !
    Watch your speed ! When you're not used to the handling of a new vehicle, you should accelerate only on the straightaways, then slow down extra early for the turns. Remember that both hard acceleration and hard engine braking (deceleration) are equally important during the break in process.

    On the Racetrack:
    Warm the engine up completely:
    Do one easy lap to warm up your tires. Pit, turn off the bike & check for leaks or
    any safety problems. Take a normal 15 minute practice session
    and check the water temperature occasionally. The racetrack is the perfect environment to break in an engine !! The combination of acceleration and deceleration is just the ticket for sealing the rings.
    Go For It !!

    Dear, I guess you did not get the process. Speed is not the issue here. You need to load the engine, means push it hard but not all the way. Lets say if you have CG125 push in 2nd gear from 2rpm to 8rpm and then shift in 3rd and just go upto 8rpm and let it go. Repeat the process for at least first 200km. Alternate this between 2nd and 3rd gear respectively. Keep in mind do not do more then 40km a day so that you do not overheat the new engine. (not to look on speedometer but do look at your tachometer)

    Process require you to load the engine so the rings can be sealed well. Slow runing do not seal well the rings and that is why after couple of yours you loose your power.

    I hope it helps now ...

    MotoMan says break it in hard, and I agree.....Don't push it to extremes, but keep the rpm on the upside and I agree. I think one can achieve better gear ratios and this also opens up the engine quite nicely

    That is a very nice guide actually. But breaking in is a very controversial topic, with a lot of, shall we say, theories makin' the rounds everywhere. But what I want to know is that a new bike, in the break in process, why can't it hit top speed and can't perform at full potential. I mean it is a new bike after all !?
