Okay all you Strom tuning genius'. I have balanced the throttle bodies and smoothed out the non-clutch chudder but it took a couple of the adjustments to their limits. The sharpness of the throttle response has softened greatly, it smells rich and the gas mileage has fallen from low 50s to 38-41 mpg. Runs well but not great. Any ideas? The air filter is fine, fresh synthetic oil change. 10.6k miles. The clutch basket was done before I bought it. Not real satisfied. Anybody within about 4 hours of Goldsboro, NC that wants to take a look? Prove just how satisfying these are? Thanks for any ideas. And no, I have not yet tried changing or looking at the spark plugs. Tomorrow.
