I recently purchased 2005 CRF 25O
I'm having a few issues which include popping when letting off the throttle and it seems to run a little hot.
The popping could also be the valves but I haven't got that far yet.

I took a look at the carb and saw that the pilot jet seems rather large a 68 and the leak is also kind of large at 100.
The main jet is a 172 which seems like a normal size unlike the rather large pilot jet and leak jet.

So my questions are
Is it OK to run like this?
Would it be better to go closer to stock size jets?

Also I do most of my riding at about 500 -1500ft above see level and I mostly 50-80f weather.
