Sometimes you just have to dig a little deeper, even when the solution to a problem seems evident. Case in point; a while back I converted my enduro bike to a dual-sport and registered it for road use. In the woods the bike ran flawlessly, but on the street it had a noticeable lean surge at small throttle opening, indicative of a too-lean pilot jet. It wasn't particularly bad and the bike ran okay, so I wasn't too concerned, especially since removing the carburetor to replace the jet was such a headache. Besides, I rarely rode the bike on the street, and I'd only registered the thing so I could compete in NETRA (New England Trail Rider Association) Enduros.
