threaded spark plugs?

Post by jellyfishmoonpie »



Hey everyone, im new to the motorcycle scene (im 17 and have been riding my dads softail heritage for 2 years). I recently bought a 1976 gl1000 that had been sitting for 6 years and began working on it. I purchase new sparkplugs and was wondering why are the tops of the plugs threaded?

Different applications have different coil attachment methods.

Oh, its as simple as that?do you "thread" the spark plug caps on or just push them on like normal? I have just become so accusomed to the non threaded ones I didnt even know the threaded ones existed.

Before you run it, change the timing belts. These are interference engines; in other words, if a belt breaks damage will occur. Depending on the engine speed at that time, you might have a couple of bent valves or you might be looking for another engine!
Belts can take a set after sitting in one place under tension for some time, and that's all that is needed for them to jump a tooth or three.
The accepted mantra for this is: if you don't know the history of the belts absolutely for sure, change them. If you do know, more than 5 years or 25K miles, change them!
'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!
