Do the cam mod. Best of all, free. Re-sale the slip on, and get a full exhaust, preferably Dasa, Monster, or Rossier.. in that order. If noise is not an issue, go for the shorty Dasa or Monster in that order. Call up FatBoy and get yourself an FCI intake. If the oil mod hasn't been done yet, do that first, and then tell the 250R & Raptor to keep up! Lol. Welcome to the site brotheran!

Search "oil mod" or "oil upgrade" basically 04-06 bottom ends lack proper oiling of the wrist pin area,so intern with poor maintnance(which is common) and sometimes just bad luck,it's a matter of time until the bottom end seizes up and destroys itself,it's one of the first mods you should look into

Cant put a numerical value on it (someone could), but you will notice a huge seat of the pants difference when tuned (jetted) correctly. The YFZ is stingy as far as numerical value HP / Mods(upgrades) go, but I still prefer mine over any TRX or LTR I have ridden. Hadn't tried the KFX yet, but assume it would be no different lol.

Congrats. You just purchased the best exhaust and intake for the YFZ IMO. Intake, for sure. You will be happy my friend! Very happy!
