Does anyone know what the GRP 08 Tuned.12 comes shimmed for for the fuel? Do i need to make any changes to the shims for 16% nitro?

At least the GRPs sold in Europe come ready for 16%. Dunno if there are different versions for other parts of the world.

Read the whole thread and you will find out that you can only use grp/ninja plugs as others have a different taper and can leak/mess up the head button.

well..., a couple of my friends are using IDM and sirio plugs with no leakages at all.

however, one of them told me that OS plugs will leak.

Anyone tried the GRP plus plugs and what is the advantage or disadvantage of using this instead of the old conical type?

Thanks in advance.

I've tried the Skyline and Vantage pipe. The Skyline works pretty well, but I think the Ninja pipe had a bit more on the top end. The Vantage had a lot of bottom end power, but seems to tucker out compared to the Ninja pipe
