I agree with this clutching statement.Air filter, exhaust, and a fuel tuner and your there.
Have you played with the weights or the clutch yet?
There's a lot of zip from those as well.
They reduce that utility feel.
I got a HMF on my bike with the silencer core , sounds good seems to flow good! not to loud but good sound without the silencer it is very loud.My interest in exhaust and tuner is not really due to wanting more power. My reasoning is that these engines aren't breathing right and running too lean which creates excess heat which I believe can shorten the lifespan of the engine. I may do the clutching upgrades and I may not.
