I have 2 stock 400exs there 07 and 05 the 05 is a slip on hmf I have jetted at 40 and main 160, it has no header mod, lid on, k and n filter. Seems to be ok do some of u think that's too much?
My real problem is my 07 I have jetted at 40 and main 165 now it runs awesome untill your high rpms and it starts to cut out. Anyone know if the cutting out is bc or to big of jets or needs more? This has an hmf full system k and n filter, sparks advanced key, lid on And spark arraster out.
Thanks for any input from anyone riding this weekend and don't want to have it messing up while I'm out. Also I live in ohio not sure about elevation leval etc
