    I got a 1/8th scale buggy the other day and I hope the breaking in is going like it is supposed to.

    It is a Kyosho Inferno Neo 2.0. So far it is fun, but seems to be no faster than my 4x4 slash. This should change after the break-in and then I should be able to run it a bit leaner, right?
    I have gone through about half a gallon so far.

    I didn't just get this for speed, but mostly durability.

    break in is different for different motors ... but yes when it is broke in you can lean the high screw a bit to pick up the power and rpm's
    ..
    The nitro fuel .. higher nitro content and or lower oil content means higher octane ... =more power .
    ..sometimes this requires adding another head gasket so there are 2 ... so if you drop in some higher octane fuel and it acts like it is hydrolocked ...try adding a second gasket .. the higher octane will detonate at a lower compression . the extra gasket keeps it from detonating too early .

    and there is the option of adding a tuned pipe vs the stock pipe ... they always help .

    there are a few that would fit on ebay ... also after well broke in there are more ways to improve power like porting and polishing the sleeve and crankshaft.

    I knew about the tuned pipes, but I didn't know people went as far as porting and polishing the sleeve and crankshaft. I will have to wait to do that when I get another motor. I just want to see how long I can make this one last since it is my first.

    Will a good tuned pipe help out with engine life? I know they can improve fuel economy with a good carb tuning from doing a bit of research, but just curious over all.

    it just works better and gives more power ( dont think it affects engine life )..if you want the max life keep running break in fuel.
    the higher oil content will prolong the motor life . and try not to lean it out to much and keep it below 230 degrees Fahrenheit. its good to check the running temps regularly while out playing .
    .
    new piston sleeve kits are not to expensive for most nitro motors . but replacing them means break in time all over again .
    .
    pipes are crucial in tuning a 2 stroke of any type ... when the piston goes down it is releasing exhaust and bringing in fresh fuel air mix at the same time . ...so good flow helps ..but proper back pressure prevents the new fuel from simply dumping out of the exhaust port .
    .
    the exhausted gas sends a shock wave down the pipe then some of it reflects at the end of the pipe . after reflecting the shock wave goes back toward the motor .. the timing of this makes a kind of seal at the exhaust port .. keeping the fresh fuel mix in the piston sleeve area.
    .
    the aftermarket tuned pipes are typically harder material which helps the reflection ,and allows more overall flow ...

    That is pretty good to know. I seem to lose quite a bit ofmfuelnfrom the exhaust port. A tied pipe will be my next purchase for the buggy then.

    I would rather go through the break-in procedure again than buy a new motor. I did a search online of the ke21r and seen what a lot of the replacement parts cost last night. It isn't too bad from what I could see.

    Thanks a lot for the info, I really appreciate it.

    np they are fairly simple to build if the need arrives .. there are a handful of how to videos to show you how on youtube . the extra fuel in the exhaust is the rich condition of the carb settings ..
    leaning the high screw a bit will help with that ... I had my firestorm ( .18) running perfect yesterday ... then a cold front came in ... oh well there will be more sunny days.

    I meant tuned pipe on my last post. It only has fuel coming from the exhaust when idling.

    I have been wanting to mess with it some more, but yeah, that cold front is a pain right now. Mother nature doesn't want us to have any fun.

    next weekend is supposed to be nice ... get yourself a thermometer if you do not have one ... the infrared ones are best for quick temp reads .. ideal temps are at the 230 F mark ... or from 200 F to 230 F
    a decent Brushless electric rc is great for the cold days ... no tuning required just charge and go ... :)
    the brushless motors last and last if they are not over volted or run at temps above 150F

    I will just have to see where I end up as I am a truck driver.
