Cylinder heads

Post by kevin s »

My son has bought a bare 1275 A+ head looking at the parts to build it up the valve spring caps and collets are suprisingly expensive, does anyone know if the ones off a 998 A+ are the same?

Here is some information;-

Does your valves have a single or triple groove stems?
Are you intending to fit single or double springs?
Single and double valve spring caps are different. The inner spring needs a location washer for the bottom.

Looks like if we get 3.56" long single groove valves which are widely available we can use the 1098 collets and caps we already have.
