You don't absolutely need jets with TORs.
Your best start is to do the following (or get it done at the dealer):
- Check you carb vacuum ports for leaks (do you have the AI removed?)
- Adjust your air screws
- Balance the carbs
This will give you a good starting point to further troubleshoot any remaining issues. If you decide to change anything, do one thing at a time and see if everything is OK after that. Nothing worse that trying to track down a problem after a half dozen mods...
