I know the purpose of a PCV is correct fuel to air ratio and not necessarily to magically give a performance boost..
My PCV is disconnected for diagnosis purposes.Not sure if its placebo but I feel like there is a slight performance loss when pulling off.
Lastly is there anyway to increase top end on these bikes without any major modifications? With my current config.Im limiting at 140 kmph (86mph) maybe hitting 150kmph tucked properly with no wind (provided my speedo is somewhat correct). I weigh around 80KGs (176lbs).I understand these are only 250s but I love the idea we are able to really ride them hard and if I can squeeze a little more performance out of mine il be happy. (:
Is 140 KPH (86 MPH) the speedo reading? If so, something isn't right. That's low for a stock bike - especially because the speedos read high.

Other than the slip-on, have you made any changes? What do you mean by a "straight" slip-on?
