Hi,
I've been put in charge of making my nephews quad faster. He has a 2008 kfx450. I've read every engine related post in three forums... riders, hq, and of course kfx450central, and decided to go with the following choices:
Exhaust: already has Curtis Sparks installed, he spent a fortune and not really wanting to change though may be persuaded to.
Intake: FCI intake, just purchased
Piston: JE 12.8:1, +2mm 470cc, just purchased
Cams: KX dirt bike intake/exhaust cams, just purchased
We're going to drop the motor today, and send it in for port/polish, valve job, cylinder bore/replate, and send the throttle body in to get is bored. Were going to call Dasa Racing and Hetrick Racing to ask for price quotes on port/polish and valve job but to be honest we're on a tight budget and as p/p isn't as critical for this engine I would like to save money in this area. Any suggestions on a good budget p/p & valve job?
Going to also look into advancing the timing three degrees instead of buying a Power Commander ignition module.
Am I making the correct decisions? Am I overlooking something? It's not too late to send stuff back. Any well informed information will be well appreciated. Our goal is to get over 55 whp after tuning. Thank you.
