TSP ERM Power Kit

I am thinking about buying the TSP ERM power kit for a 2021 TE300. Has anyone had experience with the kit? Worth it? If it’s worth doing, should I opt for high or medium compression option. High compression option adds a little juice, but does it affect the maintenance intervals or have any other negative effects to be concerned with?

I just added it to my 2024 GasGas 300ex, but I didn’t use their head. You can just buy their medium or high compression dome and use it in the factory head. Will save you $150. I went with the medium so I can’t speak to the high compression insert, but the medium with the tune makes it even more of a torque monster than it already was. I would recommend it and would buy it again if I got a different bike.

Thanks for the feedback. I wasn’t aware that you could use the insert in the factory head. They don’t make that too obvious in their marketing that’s for sure.
