Whats your elevation, temperature and any mods to the air filter/box.

 

With no other mods and if your close to sealevel you should probably be around 270 - 280 mains

 

 

I live in Los Angeles. I ride at Pismo Beach (sea level) and Glamis (??? elev.)

 

The mods I have are only the toomey's T-5 and K&N air filter with no air box.

 

Other than that it is pretty much stock.

T5's, no air box...just K&N...330 to 350. Unless Pismo and Glamis are more than 1000 ft or so...

If so, start at 350 and subtract 10 for every 1000ft about sea level...

 

 

I agree. On my stocker w/ similar mods (except I still have a box/no lid.) I've ran 340s to 360s at 300ft and 95+ temp. Fouled plugs w/ 360s, runs great w/340s. When the temp falls, I'll put 350s or 360s back in.
