Spark plug tool size ? - CB550
« on: August 21, 2010, 02:01:34 PM »
Sorry ...easy question ... but  can someone tell me the size of the spark plug tool for CB550 series bike.

Thanx.

In case you are wondering...I cant get the plug out to measure it because I havent got the right tool and I dont want to buy a new one on a "guess".   Already got it wrong once  :'(

You could get a new set of plugs and take one to the store with you.

Its no so much the plug size but the clearance issue when changing the spark plugs.  Have to use a thin wall socket to get down and access the plug.

All sorted and thanx for info.

I got one (18mm) that is both thin walled as well as short enough to access the plugs without removing the tank for the centre 2.
