hi there iv done air box mod gonna put chip in tonight once i set by pass screws and co trimmers to 12. do i start it up and thats it.
 
cheers seems spot on. idle running a tadge high i cant take it any lower il see how it goes
 
The settings are just ballpark in the chip instructions. No 2 bikes are the same but if the idle is too high and out of adjustment you probably have a bit too much bypass.

A little rise in idle is normal and i always had that when switching eeproms but you should be able to wind it out with the adjuster if the settings are spot on or close.

I did a 2000 bike with a Gabro chip a while back which had been set to the ballpark settings and the rear cylinder was running 8% Co. Best to get it double checked as it doesn't cost much generally.
