I bought a 2000 TB last year and it was running rich, It would start bogging down at about 4000rpm. I pulled and cleaned carbs and noted jet sizes. I switched back to factory jet sizes and needles. Now she runs REALLY well.
I think blueing of the exhaust on these bikes is common, mine has it. Unrelated ;but I changed to niology coils and that made the low end smoother.
