Power question

[franciscoluis]

Ok... i have a 400ex with a k&n and i just wondering if it is normal , when im at 5th gear with all the throttle the engine sounds like it has no nore power, and even the rev limiter dosn't seems to work.

This is normal, or i have to do some modifications somewhere to make the rev go higher.

Thanks

it doesn't sound normal to me. I have a 2002 400 with K&N and FMF pipes and that has never happened to me.

You need to get a different CDI box to let you rev higher. The stock one has a rev limiter.

is it expensive or cheep??

A million vendors sell them. Ive seen them everywhere from $65 to $120
