Setup needed to smoke YFZ450

[sixsicsix19]

I just bought a 02 stock banshee and my buddy has a stock YFZ450 that smokes me every time we race. So i'm planning on throwing some money into my banshee hoping i can make it faster then his YFZ450 thats stock. Can anyone help me out on where i need to start with my performance upgrades the cheapest way possible? I've allrdy order toomey t-5,v-force,k and n filter,adj timing plate, tors. i really don't want to have to run race gas either.

you can beat yfz450's with bolt ons like what your getting and a cool head with smaller domes (say 21cc @sea level with +4timing and 94oct) but to smoke them, you will need porting.

as gnr said, contact some porting sponsors to see how far you want to go.

Sounds like your on the right track, now just add a coolhead w/domes, maybe some gearing changes. Then its Porting time to go way F.A.S.T. !!

Like said above...Your on the right track. Just add a head with change able domes. Keep the air lid off and make sure that bad boy is jetted right. You shouldnt have a prob of putting him in the dust.

With just the t-5's you probably beat him but instead of the $200 for reeds you should have got it ported for $350 at fast and would be no contest. The timing plate is also a great idea.

[bbcmudtruck]

Get you some good tires for the terrain that you ride on. The stuff you ordered will be a great start. Don't forget to jet your carbs when you put on the pipes and filter.

man i beat my buddies 450 with a stock motor fmf pipes non jetted....and it was a old top end...i guess it ran so good cuz it was leAN but eventually it killed my motor with no jetting but i still smoked his ass easy. i guess it all depennds on how good u come out the hole keeping that frnt down is the key...

if i have him port it will i have to run race gas?

[jbirdshee]

i have close to that same setup and stock yfz's dont even stand a chance i just walk on them all day but definitely go with porting to just dominate

well i think what im gonna do is get everything installed and tuned right and then see where i am against the yzf and go from there. i guess if i'm still not happy with the power my next step will be the cool heads and porting

[sixsicsix19]

also i have a k and n filter that came with it when i bought it...should i keep running this filter or get me a uni-filter?? toomey said i need to drill holes in the airbox and others have told me to take the lid off??? What do yall think i should do?

[GrMeyer]

Mount the filter in the box. So keep the K&N and take the lid off. Jet the bike and it will be a new ball game. The banshee loves to breath. So keepn the lid on will b e the weak point. With the lid off. Ur jetting wold me around 300 mains needle in the middle and 27.5 pilots. With the lid. I should be around 270 with some holes in the lid. Needle in the mid and still 27.5 pilots. Put the timing at +4. If u plan on putting the timing plate on u will need a flywheel puller. This set up should get u in line for one quick bike. Also u will need to learn how to sync the carbs or ur bottom end will suck!

You raced him on asphalt or dirt?

yea i raced him on the street...do yall have any tips on syncing the carbs together ive got the tor kit installed but not sure if its sync right?? also how the hell do i get it to idle now since i put this tor kit on it will not idle and there is no idle screw to play with on these carbs?
