Fuel Mod
 

I"ve been reading through about Kev"s fuel mod ,will it improve performance with a standard air filter and pipe ,or do you need to use a K&N filter to notice any difference ,also if it adjusts the mixture is it possible to run the bike to weak ,i would be worried about burning a valve out .Maybe someone could suggest the best mods to help the bike breath better it feels asmatic :drool:

I have fitted a DNA airbox top with the standard Unifilter airfilter with Kevs fuel mod and it made the bike breath a bit better. The biggest improvement was fitting a set of Arrow pipes. With the Kev mod it only makes the mixture richer not leaner. I would recommend the above with the exhaust of your choice.
