I dont know about 2 hp but it wont be that hard. You take the case off and use the HUGE bolt they give you to remove the flywheel. You tighten it down and it pulls the flywheel off. Put the key in and reverse instructions, just make sure to tighten the flywheel on good.

don't know about 2hp, but i did notice and increase in bottom and midrange power, and it did wonders for my throttle response. they r not that hard to install...i never installed one, that is just what i've been told
