Hi I have just installed a RK-Tek head to my 2020 300 tpi.
I literally noticed no difference in power delivery or torque are these just a gimmick?
If any thing its running slight worse as I now have a bit of over run on idle/shut down.
There seem to be a lot of talk of extra bottom end and torque but I notice nothing!
