Big valve cylinder head with enlarged ports
Compatible with normal cylinders for old horizontal engines such as CT125 JA55 etc.
The old model cannot be left behind either.
This product is the first big valve cylinder head to appear in Japan and is compatible with normal cylinders!
Genuine In: 24, Ex: 21Φ, This product In: 27, Ex: 22Φ
Compatible bore sizes are from genuine to 57Φ.
Included items are head body, valve spring, high cam,
No. 7075 extra super duralumin valve retainer and stem seal.
For those who want to stick to normal engine displacement.
Of course, it is compatible with bore diameters up to 57Φ, so it can also be used with vehicles with larger bores.
8Ft is also a product that I have been looking forward to.
This will eliminate CT125's hopeless growth in the high rotation range.
This product supports up to 15000rpm.
