I bought a HRC kit for my 07 450ER. It came with the CDI box. Is there any difference between that and a Rev box? Will there be more RPMs with a rev box? Also I have a K&N (no lid) and a HMF slip on with the HRC kit, I'm looking for some more power. What the most cost effecient way to get this? And another question, will race fuel make a difference power wise as opposed to 93 octane?
i want my power to be good for the dunes. i was running a 14 tooth with my setup but my 13 seems a little better. what do u guys think about that as well.
