First maintenance service by me

Finally got some parts in and put new spark plugs and an air filter in.  At 4,712 miles and 18 years the air filter was dirty and in need of service.  The original plugs looked brand new.  I replaced them anyway since I had already bought new Iridium NGK plugs.  After seeing the original plugs, I know I didn't need new Iridium ones and contemplated putting the original ones back in.  I wanted to get some anti-seize compound on the plugs to ensure easy removal in years to come.  Apparently modern ignition systems burn hot enough to keep plugs looking like new for a long, long time.

The hardest part was putting air in the rear tire.  Tire date codes are 4203 so I'm pretty sure that they're original,  they are the Bridgestone Hoop tires.  The valve stem angle has the stem pointing to the exhaust side.  In order to get the chuck on the valve stem I had to lay on the floor and contort my arthritic body to fit the air chuck to the valve stem.  Did Honda put this angle piece on backwards?  Should the valve stem point toward the other side?  Seems to me it would be much easier that way.

Well Looks like I can only add 2 photos to a post??  The tire valve stem photos should be below.

Hi+Welcome, modern zinc plated (shinny) spark plugs do not require anti-seize, if you want to use it, very little and never on 1st threads, reduce torque to 10ft/lbs or 1/4 turn max.

BTW (Flame suit on ) you tires are Dangerously out of date !! and very possibly your drive belt, we had several oem tires fail over at the Burgman forum lately, 07+ Burg.400 uses exactly the same hoop tires as the SW600, your tires are 19yrs old !!, 14yrs past their "Normal" life expectancy.

BTW, tire valve stems are also due change. Age trumps mileage when it comes to rubber components.

Valve stems---Honda has straight, rubber, short, high speed valve stems---that allow normal chuck to fit.
Good Honda Partsman should be able to help.

Yes I know the tires and valve stems are out of date for safety reasons.  Just bought the scooter and I'll be ordering new tires very shortly, and certainly before I do any serious riding.  Probably order a new belt and variator air filter when I order the tires and maybe get a set of Dr. Pulley sliders on order also.  I'm learning as I go along here.

I too replaced my spark plugs with iridium ones. Did that at 8K because Honda said so and I had an extended warranty. Most likely will never have to replace the plugs again!

As to the tire valve...a very stupid setup from Honda, DOH. No you cannot reverse the angle, it hits the swingarm! As John says above use the shortie valve like on the front tire. It is much superior and CHEAP. I too hate to crawl around on the ground to check the air pressure.

I, too, had the shorty stem on the rear wheel of my second Silverwing as the result of a puncture on a Saturday far from home and the mechanic who was doing-up a motorbike in his private garage nearby and rescued me only having a shorty valve.
Soon after, I bought a screw-on rightangle stem which I attached just for inflating the tyre when necessary - I didn't leave it on but kept it in the cubby.
I still carry one with me, just in case.
I also carry a short extension.
I know I've said all this before.

Ed because the scoot tires are shorter than motorcycle tires ,Honda probably thought install a sideways facing valve stem. with this setup you should have a straight air chuck instead of the angled ones most garages a mechanics use.I, like most Swing owners still hate crawling on the ground to add air.
