I recently bought a 2004 Foreman ES. I know it wasnt made to be fast but damn this thing is slow. What can I do to give it some more power. I also have a KFX 700 so if I feel the need for speed I can jump on it.

What is a good pipe and filter combo for it?

 

HMF and K/N. The HMF is ungodly loud but makes very good power.

 

Yeah I know HMFs are loud. I have duals on my v-force, sounds badass

 

I have a '99 foreman ES, just bored it out .20 thou, hmf in the mail, might jet/ filter it too. it's got a little more bottom end so far, goes 81km/h only gained 1 km/h. any idea how much more horsepower the hmf will give me?

 

You put that HMF on and you will have to jet it. If not you are going to be way too lean. I've heard the HMF is good for around 5-6 hp. But that may not be accurate. But I know for a fact you will feel the difference.

 

Also this will work on all Hondas with the CV carb. Remove the top of the carb and clip the spring. Take about 10-11 coils off. Replace the spring and go feel the difference. This will really improve the throttle response and its FREE.
