has anyone had their setvalves removed or opened? want to know if you fel the increase in power as a result as doing mine very soon.
Not done it myself, but its supposed to release only about 1bhp, and if you remove he unit itself, you save about a kilo as well. Not massive, but its free to do, so…
I think I will be doing mine as well (gsxr600k7) when the warranty runs out, which is mid April. So I would be keen to hear your results. There are loads of guides on youtube and gixerjunkies…
