I put a ramair filter on today. I have a classic with cut oem silencers using map 20218.
I get a little woodpecker at low speed. But it is a lot smoother and seems to respond quicker, which i Noticed when exiting first fast corner. All smiles :)

May sound varies by map. Open vs gradual secondaries
 
Get thee all to a proper tuner!
IMHO - Tis risky tossing any ol' tune from any ol' origin into your motor.
 
Anyone know a good tuner in Southern California they can recommend hopefully they also work with tune ECU?
 
Geno, I have 20228 on my 2005. had it for a couple of years now. Was getting around 33Mpg before the new map. Went to 25mpg with the new map, but have been declining. Down to around 22mpg now. Don't care as nearly as much about the MPG as the loss of range. How does your tune compare?
I like that 20228 map, i've have ran with that map and getting ready to load it back into my bike, i have the 20226 in now, i kinda use these two maps. "Be Safe"
