    Airbox mod/restricted intake

    Yes, I ended up experimenting a bit and decided to just throw a pod filter straight onto the throttle body, Do not try that, I wouldn't mod anything with the air intake system unless you have strict control over your AFR's. I went on a ride with that pod filter and ended up swelling/scoring the...

    Engine Assembly at factory

    I know this isn't a Honda engine, but I'm assuming our engines got put together the same way. Its funny how we're all tip-toe'y about torque specs, and they just impact everything lol

    Extremely tight step assembly (footpeg bits) bolts?

    Just like @m in sc said, 6 point socket and you're golden. Plus you'll have a years worth of fuel saved from the stealerships labor cost :D

    Air intake

    For the most part, if you just do the 143 + the pcx 150 injector, it'll be more Torquey, definitely noticeable. Top speed might improve some but not significantly, maybe a couple of mph.

    New project. 100 twin (YL1'e'. Twin Jet)

    That's so cool! Never even knew that these little twins existed. What's the plan, restoration? Seat kind of looks like that double seat you can get for the trail lol :p Not my glass of whiskey as well.

    Yuminashi 238 cam

    @m in sc covered this in a thread. He pioneered the ct 125 yuminashi 143 bbk + pcx 150 injector + efie mod. Swapping the injector for a bigger one on the 143 doesn't necessarily give you better power, its just to trick the ecu into not running too lean for that bigger bore. Because the ecu...

    Yuminashi 238 cam

    A racer is great, but only in conjunction with the af2 module, obviously, far better than the pcv I have in my 701

    Air intake

    The air filter? I put on the uni pod filter, fitted it straight onto the throttle body After I scored that cylinder and piston I went with a 143 yuminashi kit and the aracer standalone ecu to control the fuelling I also have a different (bigger) throttle body now which required a bigger...
