Is this Phelps?

I have both.. If I had to choose between a banshee and my 450... I'd sell the banshee. the 450's are more versatile and a better all around bike. I bought my wife a predator a new predator in 03'. it was way better in the trails then my banshee. from that day on.. my banshee has not seen a traiI, bought a YFZ450 a few weeks later. never looked back.

I heard he didn't like the addy posted to keep people from showing up without a invite since it is a private track. none of my business.. just going by what i heard.

I dont think it was ever posted.

I thought phils was a invite only?

I would like a set for lectron also.

i've seen some.. but pricing has been so ridiculous that it was better off buying new.

I'll take them lindz, You got a PM

Very nice.

yah i got the steel tip ones from packard and they didn't seal. hopefully these new ones will keep the cases from being drenched in fuel.

Boo is looking for arms.. I'll send him a text.

are them Elka factory shocks?

are they viton tipped? I bought new ones from packard and couldn't get them to seal. They didn't have the viton tips. Lectron told me the mikuni needle/seats dont like to seal and are easily over powered by the pump. Figured I'd give lectrons set a whirl. I'll find out next season if they work.

Contact lectron, they have viton tipped needle and seat sets.

need more info about your setup to give a better starting point. Intake, reeds, compression, elevation, location.

There is the ol'girl Dave... Hardly a rigid. Silencers are a give away that the bike is from MI... lol

As far as the roll of the pilot jet. The image I posted clearly shows other wise. Sudco uses the same chart. I'm not talking about velocity at the reed. By increasing cross sectional area of reed cage you decreasing the venturi effect. Its physics. Bernouli's principle. Your garden hose theory is not accurate since the motor is a vacuum and not a pump. You would have to reverse the flow of water in your hose with the same constants. Do it this way and the velocity of the water coming into the hose is far greater then the velocity of it exiting the hose.. Its proven physics. Enough from me on this subject. I will leave it at I disagree with your theories.

It doens't say anything different then what I've said.. The pilot has very little affect on the low and mid. Its main task are idle and off idle. Your link even says If the engine is running poorly just off of idle, the pilot jet screw can be turned in or out to change the air-fuel mixture. It doesn't say.. if the bike is performing bad in the low mid to adjust the pilot/ The pilot should not be adjusted to affect the low and mid. That is the job of the needle. The engine creates vacuum and will draw a definite amount of air. This is based off parameters of the engine (bore/sroke). . With all other parts of the intake track being constant, by increasing the cross sectional area of the reed cage.. your decreasing the venturi effect therefore decreasing velocity and pressure on both sides of the cage. It dont matter if the cage is down stream of the carb. It affects the velocity and pressure of the entire intake track. Maybe someone with background in fluid dynamics can chime in. But I think this is why your seeing a need for a bigger pilot jet. The other part of the equation that dictates velocity through the intake is engine RPM. But since that is a variable governed by throttle position. It would take longer to explain. Please dont take this as trashin the vf4. Civil chat This is a more precise jetting chart IMO. Edit: Lectrons might not apply.

I will disagree with you on this one.. It will play a part in the transition to the needle circuit.. but it will have very little affect on the low mid. The needle dia and length is your low and mid. Sounds like your running a rich pilot to band aid the needle dia.

lol I just did it cuz green did.. I really didn't say anything.. My take is.. Leave it up to the builder. More then one way to skin a cat. Just cuz the guy made the pipe dont mean he knows everything. I got dyno's that show SB and BB both setup optimal with proper domes/timing and they made same HP but BB had better torque curve. Peak HP is meaningless to me.. its about usable power. I'll take a motor with 5 less peak HP but makes peak HP across a wider rpm range and better front side curve any day. JMO...

Thanks for the resize of your sig tuff guy, its a lil better.. now work on your list of useless mods that no one cares about...

Deleted mine too.

Sure this isn't from decreased velocity at low rpm due to the increased area of the cage design? pilot dont affect low and mid power.. It "meters the fuel required for the engines starting, idling and initial throttle opening. (0-1/8)" Not being a negative nancy on the VF4's.. I just dont agree with it needing bigger pilot jet due to the increase in power in low and mid.

I got about 2500 into my 350 and still got about 2500 to go. ground up builds are not cheap. I dont even have good shocks!

lower PSI settings are softer and have slower rebound. Problem is when you get to low on PSI the rebound is too slow and will pack. Also, you'll get a lot of initial sag. Sounds like you need some work done to yours.
