Not sure yet. I ordered new NGK plugs (one step colder), so I'm waiting to pull the plugs. I replaced the plugs last year, but had some issues with the gap, so I'm just going to replace them.
The tuning is tough. I really think that CPS needs adjustment so my static timing is off. Unfortunately, without a rear wheel stand the static timing adjustment is essentially impossible.
1.) Replace plugs first
2.) Attempt to adjust CPS
3.) Tune map
3. is pretty much a moot point without a WBO2 (or two in the case of the Buell). Datalogging with 2 minute rides at 2000 RPM, 3000 RPM, 4000 RPM, and 5000 RPM will have to suffice ... [down]
