Explanation of J Costa Pins wear on the variator


  1. Hi Mitch

    I was wondering if you could help me a bit :-)

    I just bought a j costa for my PGO G-Max 150 (Genuine Blur in the US) and it is on the chart on bikes for this j costa model, GY6 engine.

    They (j costa) says it should work straight out of the box, but it has no power at all. It accelerates very slowly when giving full revs, seems a bit odd like the pins doesn't have the correct weight.

    I saw your installation video and the only diff from mine is that it came with a washer to put behind the vario, maybe I should try and remove that, but on the other hand I don't see it doing anything in relation to the actual driving.

    Or should I just write j costa and ask whats up, because if I have to experiment with diff weights it will most likely end up pretty costly as they are not cheap.

    Regards and thx for great videos


  2. Tried to remove the washer but it won't fit without it mhhhh
