Just installed my EPI pink spring. It doesnt work very well in my honest opinion. I put it in did some runs down the road and around some trails by my house. It doesnt feel like i gained any pull to til about where the dead spot was. then it pulls better then the stocker. It may have gained a few MPH on top end though. The way it works i can see it working good on a stock bike or if you just want the same as stock with a few MPH extra on top end this is the spring to get. I am taking mine out. Any one want to buy it? or I'll trade for an EPI red primary spring. Only had it in for an hour. Let me know.

I noticed that you have two V's. I would love to know the results of a drag race between the two. One with the origional spring and one with the pink. I have not raced anyone since I've had my pink, so the results of having a pink are still limited to the seat of the pants feel. Not by actual race time. If you could do a drag between the two before you chuck out the pink spring, I would appreciate it. Thanks..

 

Depending on the results of a drag race between your 2 quads I may be interested.

 

I would do drag tests between them if i had it. The orange one was stolen about a month and a half ago. Also i have a pipe on mine so it would be faster anyway. I can borrow my bros GPS and see what the speed gain was. It is a good spring for all round use but i am looking for somthing more agressive. I also think i am going to get a set of duals. My single puts out great torque and low to mid but maybe a dual system will put out better top end.

 

What mods did you do to the airbox. I cut a whole in mine and it was a nightmare. IT wouldn't do anything. I had to duct tape it back up just to get it to move.

 

I put 20 3/8 holes in the airbox lid on the right side. jet up 2 sizes from stock and gave the airmixture screws 2.5-2.75 turns from seated and she'll scream.

 

gonna try my pink spring today my opinion it will work great to me epi red one engages to high rpm to hard keep front wheels down

 

Full Throttle:

Post your results when you are done please. I have a pink spring on order and would like to see another opinion. I have a stock bike so hopefully it will make a difference. The only other mods I plan are some airbox mods and a K&N filter with a jetting change.
