When one thinks of modifying his/her ride for better performance, there are a lot of questions that starts creeping into one’s mind about what should be done and what should not be done with the engine, gear box and clutch
Let us put some light on the clutch for now. One would think what could be done with the clutch to improve its performance! Let us clear some doubts or myths related to modifying the clutch. In terms of performance, one can only enhance the performance of the clutch and not overall performance of the bike. Clutch Porting is what it is called. Now you would ask me what does that mean? In order to give you a clear picture of clutch porting this is how it looks like:
Now that you have got a picture of it, you have an idea about what rotates in that cylindrical casing on the right side. Getting back to clutch porting, if you have observed the image carefully you will see that the casing is sliced and not directly in a pan shape. Now these gaps play an important role for the working of your clutch and gear. These gaps provide inflow of engine oil into the clutch assembly, which in turn helps in creating proper friction so that the transition from one gear to other is smoother. Good clutch housing means a smoother engine and less vibration when you pull it for the top slot. Clutch housing in a bike differs from manufacturer’s perspective and the design of the bike.
One might ask what is clutch porting and how does it improve the performance/durability of clutch plates? Clutch porting is a process where the clutch housing is drilled i.e. slicing the clutch housing and creating more gaps to make way for more oil to flow in the housing. This helps in better friction and improves life of clutch plates and less vibration in higher revs. This will surprise you because it is noticeable from the first crack of throttling.
