so the choices are as follows : new timing chain, tensioner etc - excuse my ignorance but what improvement would this give?
electronic ignition seems fair enough
new jet & needle - like for like?
clutch - what kind of mileages do they generally last for? (average use)
improved radiator
new water pump
sportier camshaft - obviously dependent on type of use envisaged
head clean-up, valve grind/clean-up
I shall be taking the 998 engine out of my Riley Elf during the restoration so these hints or tips would be useful!
Nothing.
Nothing wrong with points if you can set and service. Electronic it great if you can't set service points.
Needle depends on what you do to the engine.
How long is a piece of string? Easier to do with the engine out and if you are taking the Assy off you may as well change the wear parts.
Rad not really if there is nothing wrong with the current one.
Water pump if it needs changing otherwise no real need.
Cam pointless unless you are having some good head work done.
If that is all you plan for the head then the cam change is a waste of money.
