Yeah I have checked, but not many people on there have standard intake and exhaust.

Just to update, I fitted a 138 main jet and raised the needle by one notch. Runs well, sometimes get slight popping on the overrun so can't be far off. I am using a Motad silencer which is slightly quieter than stock.

Mine pops on decel too...also, with a ball end long Allen key, it's possible to get the top off the needle housing with only the head stay slackened off, I got it down to ten mins to change the needle clip now !

This is an interesting topic. I have a new CRF250X that a dealer made road legal (inc black plastics and an aftermarket exhaust).

Had one day out on it and it was all well and good except on the tarmac between trails, approaching 50 and the bike seems to hold back, I suspected the jet and this thread makes sense. I'll check out that web site.
