Talking about racing motorbikes is endless and I never get bored working on racing motorbikes, the challenges I face are what make me happy with racing motorbikes. upgrading engine power nowadays is not a unique thing, but this is rampant among young people today, young people my age now like big power and torque, one way to bore up the engine is by custom cylinder heads, even motorcycles. Bore-ups nowadays have used a lot of pick-up pistons, such as carry car pistons, L300, some use truck pistons.
when it comes to engine durability, we don't really think about it because if a motorcycle has been bore up, the durability is no longer there and it often breaks down at any time.
Today I will discuss how to upgrade the power of the charisma motor, how big is the piston and block size that can be applied to the charisma engine, the charisma motor block that is commonly upgraded by young people today they often use pistons with a diameter of 64.5mm, you can also use pistons. honda tiger oversize 100, the engine capacity to be 190cc even up to 200cc,
To be able to use the Tiger piston on the Charisma engine is not easy and not easy, the first part you have to do is to make a deeper hole in the space where the tongue enters the Tensioner must be added meat or welding, and also the boring entry hole in the crankshaft must also be enlarged with how to lathe, because if you use a large piston automatically the boring must also be enlarged in size, if the thickness of the cylinder block meat with the oil channel hole is still safe to install boring 62mm diameter.
if there is still a boring residue of 2mm, the piston that can be installed is a maximum diameter of 58mm, the power that will be obtained is 160cc.
if you don't want to bother customizing your motorcycle engine, use workshops back and forth, you can also buy bore up packages that have been provided at speed shops or racing workshops that already provide complete bore up packages without having to be tired of looking for reliable mechanics, but by buying a bore up package like this, in most of my experience the engine power will not be satisfactory.
standart is the safest choice and there is no safe word for custom motorcycles.
