Experiencing a lack of power on Yamaha bulldog. If I put dynojet kit stage 1 and K&N air filter without changing the originall pipes would that increase the amount of BHP? And if it would how many BHP I can expect on top aprox.?

Stock jetting is usually lean for epa purposes, so rejet will help even without replacing the filter. It will also help throughout the power-band, so though it may only be a gain of 2hp, it will probably be 2hp or more over the entire the rev range.

Dynojet kits are almost always way too rich. Just let your mixture screws out a couple of turns first. You can use K&N filters without rejetting. You really only need the dynojet kit if you are running straight pipes.
