jetting questions

[snowfreek20]

could anyone tell me what style of main jet are in the carbs of an 03 rx-1? are they considered a large round? I am switching them out to 165 because i put filters on! So my next question would be if I were to change out these jets would i have to adjust the air screw? Thanks guys

Really don't know what you mean by [large] round? And no need to adjust the air screws if it was running fine before you started. Also a can of carb cleaner at this point not a bad idea either for cleaning. Just sync the carbs when your done. Also I would change the springs in the carb. The silver spring are working fine in my sled. And always check plug color after a few runs.

no, they are the small round

where do you buy just the carb springs?

If you are going with the filter kit I would suggest 65 mians and 22.5 pilots. The pilots will really liven it up and I would not even bother with the springs. Also go with the cr10ek plugs. This package will really liven up the sled!
