Reddit mentions of Driven Racing 520 Steel Front Sprocket 15 Tooth for Suzuki SV650S 1999-2008

Barely...

I have three responses. 06 SV650S here. 520 kit (-1/+2, Chain and Sprocket below), K&N, DanMoto XG1 baffleless.

0) Do a Chain and Sprocket first. IMPO the PCV does little to increase acceleration, the changes are more dynamic the just raw power. (I don't know what a Zero Map is). Replacing your stock 530 pitch chain and sprockets with light weight (NOT Aluminum) 520 bits is one of the coolest upgrades. The 520 kit improve acceleration, wheel horsepower and torque by reducing rotating mass.

1. PC V with a Dyno tune = YES! << I'm planning to get this done but not for power, I'm looking to lean out the bike for efficiency after the chain and sprocket set. I want better mileage, lower the richness.
   
   
2. PC V with downloaded maps = NO!!! << I removed mine and enjoy the bike more. It runs rich either way. Without the PCV the bike seems better across the power band. I have added a couple maps, some changes, still always rich.
   
   Note: I've had two NGK cr8e spark plugs fail/foul in the last 6 months. Care Extras with you if your running rich.
