So, does it seem (lean) unresponsive, takes forever to get going?
Or, does it seem (rich) burbles, smokes?
The DEK needle is 1 step leaner 1/8 to 1/4 throttle.
Its a tought one, most the bikes I setup run around a eek needle. Mine has an eel, and I am going to try an eem. Its a pain to do, but lots of times just when you think its running ok, you try a new needle and get it running better.
