    Larger pulley on the crank means you are spinning the gearbox faster so increasing windage losses. A smaller rear sprocket (or larger front) is likely to yield better results.

      P.S. Rear wheel rpm is required to achieve top speed and with only 50cc's tooth count on front and rear sprockets is a critical part of tuning. Probably going to need a box or two of sprockets for your testing. This was Captain Odvios's suggestion 😁..

    • @TheGalifrey

      It shouldn't be significant as the gearbox itself already has a primary reduction. 1:1 with the crank should be the same as the base bike the original engine came from. A small amount of ATF in the gearbox over the usual oil might help with that.

    SUFFERING IS OVER! To hell with the choked exhaust duct theory. Or it at least needs some further research.
    The belt drive probably adds at least 5% losses so it probably has already about 15 crank hp. I am eager to see if you can push it past 20 with some tuning. If it now has torque peak at 14K, the potential could be huge.

    Watching you apply apoxy to your 2 stroke engine reminds me of in 1968 when I was 16.
    I had a Harley Hummer 175cc 2-stroke bike.head almost no power. we determinede it needed more compression. My father worked on space capsules at McDonnell DouglasAerospace company. He sealed the craft. He brought some heat shield material which is called Avacote. It resists temperature to 5000° F. We filled a portion of the head. It made good power. It only lasted a short while being heat shield it did its job a slowly melted. 🐌

    @MikeyAntonakakis Před 6 měsíci +26

    You should be able use a beam-type torque wrench to measure the running torque of the gearbox/pulley setup to get some idea of the torque it's eating. Turn from the crank with belt and spark plug removed to get a baseline (basically just resistance of piston in cylinder and rotary valve), then see how much it changes with belt installed and pulley tensioned. Even 1Nm difference would be more than 2hp loss at 17k!
    And I don't know if you're there yet, but maybe it's almost time to start thinking about the engine dyno again now that the engine is running pretty good. I think this fits with the "lowest hanging fruit" approach that you've been taking (which is a very good approach for your situation btw!). I think you're quickly getting to the point where the belt->gearbox->chain reduction complexity is becoming the lowest fruit...

      I agree, the losses would be very interesting at this point. It might be producing much more power than measured and so the approach to gain more might be different.
      Also, the engine dyno would be much better. The swedish "Tvåtaktsmeken" made a really neat dyno with hydraulic pump instead of an electric brake. Seems to be consistent, easy to use and precise. That truck brake doesn't seem to be a very good solution apart from it being easily controlled with the computer.

      @@viktorandersson7819 yeah water brakes are cool, I used to use one for a 600cc engine when I did Formula SAE (Formula Student). I think most or all his issues with the engine dyno were input signal issues (vibration in load cell and interference on rpm signal) which should be easy to solve, then just PID tuning for the control loop. At the time, though, I think there was often confusion between dyno issues and experimental engine issues.

    You need a slide-trombone style exhaust so you can lengthen and shorten it based on the time of the exhaust port opening and closing.
    Should be something you can make out of dimensional tubing on your tooling there and adjust it based on the RPM through the crank sensor and a small spring return solenoid or even a linear motor and some kind of tiny computer like an Arduino or Raspberry.
    Set yourself a 'star-and-idle' point and then have it draw in shorter as the RPMs climb toward max RPM and if it is not adding any load or friction to the engine's output, it SHOULD allow you to super-precision tune your scavenging to reach the very max it can be.

    Alex, The machining of the head to accommodate different port geometry is brilliant! The ability to Dyno a series of runs, document the test, then remove the current designed port and install another slightly different is just dam smart thinking outside the box. It is always about, just one more thing, that you surprise us with! You need to get a printer or interfaced program that can document gains or losses for comparison.

    The well researched rule of thumb for duct exits I published ages ago was that the smallest area should be 75% of the Exhaust Total Effective Area at 1.5X the bore. Then a transition from 75% to 100% at the round header diameter out at 2X the bore - so you still havnt got it right - just trying to help - from Wobbly.
