If you do a search on this forum for 'Flywheel Weight' you'll find lot's of info. By the time you get back as far a April 2002 you'll be bored. This topic seems to come up several times each month and the information is mostly repetative.

Here's a website to checkout:

i dont have much trouble with stalling untill i get to a long steep hill and its hard to hold a steady rpm. i also herd that a flywheel will increase the engine braking? wich is someyhing i havent yet learned to deal very well with yet, only have ridden the bike twice. also how does it effect how fast it revs i like the acceleration but its proness to stall scares me when attempting large hills i curently run 14 49t gearing and would like a higher top speed as i ride in the ls vegas area i checked out the search and did find some info but i need more help. 99yz400 only engine mod white bros muffler any other mods would also be appreciated :)
