kevinx...i saw a bike yesterday at laconia get dyno'd. it has the v,1 cams, lloyds vfc3, vic filter and mufflers...not sure which ones. This 2010 XC turned 105TQ and 96 HP....thats about a 25% increase on HP and a 18% increase in TQ.
On the other forum it is said that Arizona slammers exhaust with a pcV and dyno turns 110HP and 111TQ.......still waiting to see a dyno sheet of that.
kevinx--have you dyno'd a xc bike and what are the numbers? The mags got 78HP and 90TQ on a all stock bike at the rear wheel.
