here is my set up
srx piped viper with stock viper gearing. 250lbs rider
HC's with red spring
5.3 heel
4.3 tip
3.3 center
48/36 dalton with green spring at 50deg
sled engages at 4200 about and jumps right to 8700rpm and climbs quickly to 9000rpm.
temp was 32 degf or 0deg C
sled has never felt so alive I had the dreamo up to 187km or 117mph on a rail bed and still felt like it had more but ran out of room.
so I can only imagine how it will pull if i get rid of my over rev.
So what do you guys recomed should i add a gram washer to the tip or shoudl i take out the middle whieght and add 7gram to the tip.
or what about a grey spring.
anything helps thanks Jay

MY GUESS THOSE GUYS WILL SAY PULL MIDDLE AND ADD WEIGHT TO TIP. PRETTY EASY FIX. 3:16 (yammie tony)
That is a very low helix for a piped viper. Add 1 washer inner & 2 to the tip.I would use a steeper helix.

also starting to wonder if my power is at a higher rpm from the modifications to the pipes, sence if never seen those numbers before, running 8dn-20s with 51/43 reving at 8500 and 8600 on top and would have trouble breaking 175km
