Questions and answers
Hey guys I have oil dripping from crankcase overflow, very minimal, doesn’t happen on idle only when been riding for a while, I’ve done an oil change and correct amount of oil displayed on dipstick when warm, what could be the issue/options
Oil dripping from the crankcase overflow on a Honda CBR125R after riding for a while could be caused by:
1. Overfilled engine oil – too much oil can increase pressure and cause overflow.
2. Clogged or dirty oil strainer screen – this can restrict oil flow and increase internal pressure.
3. Damaged or worn sealing rubber on the oil strainer screen – may cause leaks.
4. Oil leaks not properly fixed – such as from the crankcase cover or other seals.
Check oil level, clean the strainer screen, inspect seals, and ensure proper installation.

Hello there, my name is Traydon I have been riding for about 2 months now I’m completely new to keeping motorbikes Recently I’ve had an issue with my motorbike it’s a Honda cbr 125cc 2011 model. I have an idle problem will start but struggles to keep idle and have to keep using the throttle from it not cutting out it also cuts out at traffic lights due to not liking to stop Revving. Tray.
The idle problem in a 2011 Honda CBR125R that struggles to maintain idle and cuts out at traffic lights could be caused by an issue with the air cut valve or air cut system in the carburetor. Even after a carb rebuild with new jets and seals, the problem persisted until attention was given to this specific component. A faulty or malfunctioning air cut valve can cause over-revving, poor idling, and stalling when coming to a stop.
