    Very few people, in the overall market, care about a turbo. It just makes no sense from the manufacturer point of view. Turbo would introduce a brand new set of issues with years of debugging.

    That's a lot of matt black plastic on the new top deck. Does it have some kind of UV protection because that stuff tends to go grey and scratchy from sun exposure.

    I find the GP kinda boring...

    Think I might know whats going on, I think.

    Had a closer look at the log and it seems to only kick in in the 2200 - 2300 RPM range. My guess is the large difference between 1920 and 2240 timing...

    Weird timing fluctuation just off idle

    Anyone know what might be causing the ignition timing to be jumping like this? I'm getting this between 2000 to 2400 RPM. It makes the off idle ride very rough sounding and just doesn't feel good.

    Cometic can make any head gasket you want. They have different thicknesses in stock bore size so I'm sure they could make large bore ones.

    There's nothing in Stage 2 for that ski that would require higher than 91 octane.

    93 would only be needed if you increased ignition timing or added ET142 charger.
