Pro circuit t4 vs hmf sport

[2004ex]

As of right now i currently have a pro circuit t4 slip on, k n air filter, and a rev box on my 400ex. It seems to me with the t4 i dont have much low end so i geared it down but still didnt like it. A buddy of mine is wanting to buy the t4 so i ordered a hmf sport series slip on. Will this give better low end then a t4 or should i have just kept it. thanks for the help

Keep the t4 and spend some money on a cam. That will help alot.

You are not going to feel much difference. You should have got a full hmf.

I had the T4 on my 400 and it was fine, did you try repacking it? repack it and you should leave the packing loose i think for more low end.

i could try repacking it but ive already oredered the hmf and sold the t4. i got 150 out of the t4 and gave 230 for the hmf so i didnt think that was to bad.
