Dynojet Springs VS Interstate Springs

[Forge]

I purchased a Dynojet  Stage 1 kit for my 99 IS. I have a stock IS Exhaust with 5" cut off my piggies and triple tips installed (as loud as I want). I also have an unmodified airbox and newish stock air filter. I have new 35 pilot jets with the screws at 2 turns out and she still smells a little rich there. I'm about 700 to 900 feet elevation here in warm San Antonio, but also ride in the hill country where I may sometimes ride up to 2,500 feet.

The Dynojet Springs are longer than the IS springs. I'm sure there are different spring rates. Should I go with the Dynojet springs, or the IS? I want more punch when I want to play, but don't want my mileage to go to heck if I am cruising conservatively. The kit of course says to use their springs, but that is probably if you have standard Valk springs. I'm new to Valkyries, but not to bikes and modding them, so I'm picking the brains of experience with Valks.

Test the springs and use the ones with the least spring tension, should give you the quickest throttle response.

Sorry not familiar with the Dynojet springs.

Using this logic, wouldn't no springs be the ultimate?

Yes, WOT all the time!!

For you yes, for those with reading skills, they would "use the ones with the least spring tension" not NONE. Hope it works out for you.

the vacuum slide spring acts like an accelerator pump. open too much too fast and the engine will bog.

[Pete]

Vacuum slides were used to prevent the operator from manually opening the slides to much, to fast and causing a bog. If the springs are to light the idle will increase and in really to light spring cases or no spring cases the loss of throttle control could result in over reving and engine damage.
