So how do you think the #6 spring will compare to a Dalton O/B? The numbers look very close to the O/B.

Picked up the springs today.
I really think the ones I got are just what some of us needed to be quicker in short drags.
Thanks John..

What I like about the higher stall springs you can run heavier flyweights for better belt grip and torque and still get in your best hp range as fast as lighter flyweights. It also tends to hold that peak rpm area for a longer period of time. The slightly heavier fly weights don’t over rev as fast and get you out of your peak rpm range as fast. Great idea on Johns part coming up with these springs. The spring I love and is similar is the HPD plain with a 30-235 rate.

Theres a spring not too many people use, but I love it...it was one of my firsts with my stocker and was just completely useless...but now, I wish I could tell it apart from a stock spring...I use it in my 800 every now and then when we do hill climbs...

just been using the same ol' "go to" o/bl spring for about everything else. its a good trail spring. dont care who thinks its "too much stall".
