Probably easier to work on the full size model if you could find one and could afford it.

OK Richard, time to break open the piggy bank!

The last 19 working days I took the CB400F to work, every day, and sometimes the long route, sometimes the short route, but an average of 150 km/day. The weather is perfect, cool in de morning and hot in the afternoon. To keep it comfortable I ride along the dike in the afternoon, the cool wind from the water cools me down a bit.
Sometimes I park the bike and do a little walking for my back, and sometimes I sit in the grass to enjoy the view. I depart from home around 7, just after my morning walk, so I'm at the office around 8.30.
Next week the CB400F stay's home (it needs a valve check, oil change, and general maintenance), so the CB450K0 has to deliver. I'm also planning to take the CD50H to work one day next week, but only if I wake up early, since it takes me 2,5 hours for a one way ride.

The first thing I check is the status of the spark plugs, a plug chop in the area 4-5 K rpm area reveals how the bike is doing in the area where the pilot circuit and valve work together.
Cylinder 1 and 2
Cylinder 3 and 4.
I can see that nr 2 is a little lean, 1, 3 and 4 are nice, maybe 4 can be a little leaner, I'll adjust nr 2 too. Oil was good, oil filter was clean too. Air filter was really dirty, so I replaced the air filter. For the rest I didn't find issue's or things that I have to work on, but I'll check the brake pads of the front disc brake as well. Furthermore, I checked the tire-pressure, front fork bearings, rear fork bearings, rear wheel bearings, but all in good shape, and no adjustments needed. All lights are working, including the winkers, and the battery shows a healthy 13,2 V. Tomorrow I will check the wiring and connectors, measure compression and do a leak down test, after I adjusted the valves on a cold engine.
If everything is all right, he bike is ready for the next 6000 km before another oil change has to be done. If this weather will be around for a while, it won't take long.....

Glad your back in the saddle and able to enjoy rides in some beautiful scenery.

Yes, 3 and a half weeks holiday is exhausting, we saw a lot of sunrises and sunsets, and we ate a lot of food (we went to Greece and Spain), so time for the bikes again.
Paella in a huge pan, made by the parents in law (my oldest son has a Spanish girlfriend, so we went to Spain to meet the parents), My youngest was in Greece, doing archeological work on a remote island, so we visited him too. So technically, we weren't on holiday, but on a family trip
. I tried to explain this to the CTO, and asking for another two weeks off, but he didn't bite....

I'm almost motivated to get a new job, farther from my home! Beautiful imagery, thanks for sharing, as always!

Where in Spain do the in laws live? In the 1980's I was stationed for 4 years at Torrejon AB which is right outside of Madrid and lived in a small town named Azuqueca de Henares. I loved the people and the culture there.
