Can someone put a number of RWHP it will "feel" like if I go +3 on the rear? I believe there is no real HP gain but if it feels like it does can someone quantify it? Thanks
You can't believe everything you read. You didn't lose or gain HP when changing gearing. The Law of Conservation of Mass (energy has mass as well) states that mass (or energy) can neither be created or destroyed in a closed system. In other words, if nothing is added to the motor to add more hp but the output is just transmitted through different gear ratios, the power output of the motor has not changed. It is just represented in a different way.Interesting article on actually losing hp by increasing gearing;

Most definitely,i've seen those big 330 rear tire/wheel combos show a loss of 25 rwhp on a dyno,also losses from a sticky tire over a harder compound tire,extended swingarm with longer chain,etc.Don't change anything to motor when go 240 or extending but that uses up power too.
