I briefly read over the instructions for the 230F power up and it's pretty much the same for the 150F. If you have trouble with the install, use the "search" feature. If you can't find what you're looking for with "search", post a question, lots of great folks here with the same passion you have, Dirtbikes!!!
So, that being said, here are the recommended** part numbers for the POWER UP Mod for the 2003-2005 CRF 150F.
-99103-KPT-0420-Slow jet (42 being the size, stock is 40)
-99113-GHB-1150-Main jet (115 being the size, stock is 98)
**These parts might not be right for each and every 150. Proper jetting is affected by temperature, altitude and humidity.
If you install the parts above you also need to do the following,
-Remove the snorkel from the top of the air box, you need to remove your seat to do this.
-Remove the exhaust baffle from the end of the stock muffler.
-Buy a hi flow air filter, TwinAir or Uni.
-You might also consider removing the backfire screen from inside the airbox, this will help increase the amount of air entering the carb.
Get yourself a Service Manual for your bike, everything you need to know is in there.
Good luck with this easy modification, you will notice a considerable difference in power after you do this.
Sorry to bring this mod back up again, but I've PM a couple of different people that have had success with this mod with a question and haven't heard back from any of them. My problem is with the needle set part #. When I called my local Honda dealer he said that 16012-kpt-921 didn't make any sense to him. I wanted to verify the number, or see if this was a common problem.

air is 50% of the required materials for combustion.
if you dont have air then you dont have combustion
Actually if you want to get technical about it, air is 25 percent of the requirements for combustion. Air, fuel, compression, ignition. I think what crf150guy was trying to say was that starting the bike does not require a high flow filter. More air is not going to make it start easier, unless your talking about jetting, which in this case were not. The stock filter will let the bike rev all the way to the limiter, therefore stating that its getting ample air to run, just maybe not to full potential. It gets more than enough air with the stock filter to start first kick. If more air into the carb meant easier starting, then I guess we wouldnt have chokes would we?

you can save money and buy the same jets from parts unlimited. they are the same parts just that they dont come in a baggie saying honda on them.
just to say my .02
my jets were real cheap from the dealer.
