  • Break In Period

    I need to know what the break in periond would be on the 88-92 Gixxer 1100 engine. What RPM's to keep it under, and for how many miles.

    Thanks Much!

    i would think it would be the same as any engine.

    under 5000 for 500 miles, under 10000 for 1200 miles i think is what my kat was.

      Just take it easy on it, Dont stomp on it, and vary the RPMs. Dump the oil at 500 miles.

        Actually, dump the oil at 30 miles, 100 miles, 200 and 400 miles. At 600 miles, pull the oil pan off the bike and clean it out. The shavings and honings that come out in the first few miles will do the most damage, and it will decrease from there. I know you want to have that engine break in as smoothly as possible...

        KNOW THIS:

        During break-in, the engine needs to come up to temp fully and kept there for a while. Always let the engine run for at least two minutes before putting it in gear during the break-in, and try to stick to making longer trips (a couple 150 to 300 mile trips is better for the break-in of an engine than a couple dozen runs over to the local grocery, blockbuster, etc). I always break in bikes by simply taking a series of progressively longer mini-road-trips, putting along steadily, so the piston rings hone in tightly to the cylinder walls...

            I know there are some on Max-Suki who breaks in their engines that way with good results...

              I have serious issues with his "method" as being bad for the engine over the long haul (because of increased wear at the rings during this accelerated break-in procedure, and because of blow-by while the engine isn't fully seated). Yes, you'll probably see faster RPM increases quickly this way, but the same is true of any time you remove material between the rings and the cylinder walls because you reduce friction -- the question is whether at 10k miles, the engine is still producing maximum torque or being affected by blow-by from poor seating of the rings instead.
              It also ignors the fact that he isn't responsible for your health and safety -- engines that can crank through some mismatching of parts at low RPM's are apt to seize at higher RPM's if pushed to quickly...

              If you really want to bother, get a throttle lock, put the bike in second on the centerstand and let it run at 2k RPM for an hour. Then 3k, then 4k, 5k. Then go repeat it under a real load. The factory, which is responsible for the engine under warrantee and most benefitted by good reputations over the long haul knows what they are talking about...
