Hello "Omegawatt", and welcome to NSR-WORLD.COM! 😊

As mentioned already, we don't allow specific jetting discussion in the open/public area for historical reasons. Basically, everyone's setup is different, even if we're just talking "stock" derestricted bikes, and a setup that works for you may very well not work for someone else. It happened in the past, where someone recommended settings that [possibly] seized another members' motor, and they threatened NSR-WORLD with court action over it. Since then, I banned it.

What I can tell you is we found the standard setup is often richer than ideal. I can only speculate that this is to compensate for the varied topology in Japan, where bikes could be expected to run anywhere from sea level to up in the mountains. There was a massive mountain road riding culture in Japan back in the "race-replica" days, and I don't think manuafacturers could afford to have motors seize because of fun "at altitude".

Contrary to the above though, we have found that in recent years we've needed to increase the pilot jet size due to ethanol content in the fuels. Have you checked the 2T pump is set correctly, and not over-oiling?

Just for reference, the standard carb setting can be found in the Technical Section. I don't expect it will help you, but may benefit someone who stumbles on this thread at a later date.
