I have an Apache RTR 180 (Carbureted)
Sometimes, when I downshift, and when shifting down to 1st gear (to stand still), the RPM shows somewhere around 2000. The normal idle is around 1200 - 1400 RPM.
I must release the clutch a little bit to slow the engine back to 1200 - 1400.
This happens regardless of the temperature and even if I have only driven a few kilometers..
What would be the cause for a high idle? What can I check and how can I fix this issue?
