this is a great site, but i don't understand all the numbers, i just want the best spring for trail and some dragging. i know that this is simple for some of you, but i just need k.i.s.s -keep it simple stupid for me, and what does the stall mean and why is that good for some springs
thanks

 

Hey there Que....

I'll keep it simple. The higher the stall # on the spring, the higher the engine has to rev before the clutch engages to propell you forward. This is a benefit for drag racing as a higher stall spring will actually break the tires loose from the ground making it easier to do full throttle takeoffs without raising the front end. The drawback to having a higher stall spring is that it may make tight trail riding tricky.

The shiftout # is how high the engine will rev until it shifts into a higher "gear". You'll notice with a higher shiftout spring that your engine rpm's will be higher throught the range. This is a benefit for KFX's that have a modified intake and exhaust ,as engines which have these modifications will make their peak horsepower at a higher rpm than a stock engine.

I made the mistake of installing a high stall/shiftout spring in my V when it was mostly stock and quickly found out that it really hurt the engines performance. Without the other modifications, a high stall/shiftout spring will do more harm than good from a performance standpoint.

If you have a stock V, you might want to go with either a EPI pink spring or a Dalton Blue spring. The engagements are similar to the stock spring and the shiftouts are a little higher than stock. You'll notice a good improvement with these springs with a mostly stock KFX.

Good luck!

 

What he said^^^^


The stall rating of a spring tells you how many RPMs you will have to turn before the bike moves. Your best bet is to get ahold of Dalton Industries and get his stuff, he has a ton of time put into the V and will get it moving just like you want. I have his entire clutch kit along with a few other clutch mods and my bike flat rips. If your bike is stock I would suggest the Dalton Blue Spring, it is great for the trails and I even did real good dragging this last weekend. The Dalton Orange/Blue would be next choice and is what I run if I will be doing a lot of drag racing. I will tell you that I have had decent luck with the EPI Pink spring in my wifes V. If you have any questions feel free to ask, I live for my 2 KFX 700s, you would be doing yourself a big favor to go check out KAWIERIDERS as it is a never ending source of info on the V.

the mods that i have are the duel pipes and the jet kit, which i have to re-jetted, so will the blue and orange spring be my best bet with those mods or the epi pink?

 

Que..

stock airbox with pipes-----Dalton blue/EPI pink

Modded airbox with pipes---Dalton orange/blue


You have a way for the air to get out quickly, but unless you make a way for the air to get in quickly"air box mods", you'll never have your V running to it's potential

If you really want to make your V move, you should follow desdak4's advise and give your bike the full Dalton treatment

 

thanks guys you've been a lot of help,is k & n the way to go on the airbox ?

 

I'd go K&N but do a few other things, get the outerwears for it and also use the filter grease...i mean alot, it seemed to me that the filter wasnt having as good of a positive seal as i'd like so i just used alot of grease and that seems to have fixed it. If you dont want to get the outerwears, oil it a little more than normal because the dust will pull the oil out of the filter.

Another option is to get the K&N and use the stock foam over it, this will allow for awesome filtering but the flow will be reduced. Depends on if you want alot of flow or filter. I think the best balance is the outerwears and then the K&N.

You could also go twin air or Uni, if i didnt have a K&N i'd probably get a uni filter and put a filter skin on it.
