Lean and Mean

[DGShannon_imp]

Always felt the FI was spot on when my bike was stock. Never felt any hesitation or the feeling the back was holding back. However, every bike has its own character within the same model and can be tweaked with a PC5 and a good tuner.

Below 3,000 rpm, mine is just amazing. So smooth, great torque. Makes me feel for others here on the forum reporting problems with theirs. However, once I cross 3,200, on up to 4,000, there is a character change. Never stumbles, feels rough, etc. as if FI was off, but it just becomes strained feeling. Almost choked down. Looking at the PCV map, elsewhere in the forum, I see that the greatest correction numbers appear right in the rpm range where I sense this. Gives me some confidence that all I am feeling is the FI shifting into a too lean state. If further break-in doesn't change things (engine loosens up a bit more) I will certainly try a Power Commander. I was hoping someone else may have already experienced the same, and could say for certain that doing so would resolve the problem.

I think that you just need to complete breaking in the engine and you will find that it smooths out and frees up a lot. Mine seemed somewhat strained and buzzy at first above 3000 RPM, but is much better now that I have a few thousand miles under the belt.

Also, it may just be my imagination, but I installed a K&N OEM Air filter after only 1000 miles and it immediately seemed less strained at 3000 RPM and above.

Thanks for the feedback. Here is hoping I experience the same.
