Ok I've been told all the 07s run lean...I have a 07 RKClassic and it runs fine. I do have the 5th gear noise but am getting used to it. The bike never stumbles or pops on decel and performs better than expected. Color of plugs is tanish/grey. One wrench says I need to get a fuel management system another says it's running perfect leave it alone. It does seem to run warm but not hot...I even put on the Kury shields but they broke and it seems fine. If it's running this good why would I need fuel management? Color of plugs is good, accleration is good, and it performs great. Once I do ad ons I know something will be needed but until I can afford that do I need the fuel management now?

 

'07's do run leaner then prior years..
If your happy with the way it runs and sounds - DO NOTHING
Want to improve the performance - sound & run cooler - Do the Stage 1

 

Sounds perfect.Just make sure the color on the rear plug is the same as the front. If they are the same then i wouldn't mess with it, unless you want to get some more power out of it.

 

Thanks guys that's what I was thinking.
