These mods seem pretty sweet, just wondering if they would work for our bikes too.

it should be almost the same

a crf150 and 230 is the same bike but the 230 is bigger

What mod or mods are you referring to?

Ship killer 6666 is correct. The bikes are virtually the same. Smaller wheels and tires on the 150 and a little less horsepower but most everything is the same.

I'm referring to the step one mods, jetting, and removing baffle, + airflow restrictor in the intake. Sorry should have clarified, do I order the same parts to have this done? The 230 must be a bigger motor, therefore if I used the same jet they speciy in the how to, wouldn't I be running ultra rich?

Yes, you would be fouling plugs every hundred yards.

Here are the recommended part numbers for the POWER UP Mod for the 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 )

-16012-KPT-921-Needle set

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 or modify 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.

Good luck! This mod really wakes up the CRF 150F.

I was on another forum where they reccomended a 108 as the main jet, you reccomend a 115? MORE POWER!? Also, If i remove the snorkel from under my seat can water get into my intake? Am I increasing the risk of becoming water logged at all? I can't wait to get paid!

Hi. Hoping you could clarify, is this needle & jet combination applicable for the 2006 CRF150F or earlier years or doesn't matter?

Thanks!
