#30 Friday 19 280km 20-15*C 15:30- 19:30
I could not miss the paus of the rain gods. Another doze of STP 5-1 fuel additive to clean engine inside. Carb cleaning has been successful so far. Reducing pilot circuit fuel after each ride.
Eventually sooty chambers, piston domes, ex valves and ports after a few episodes of too rich jetting. Bad fuel tricked me to jet richer to get engine to run evenly.
Hopefully cleaner now.
The fuel screws will be reduced to next ride. I could not get any popping sound during throttle offs at high revs/speeds.
I'll set the valve lash too. 125-75 cam.Ex has little bit more than cam spec (in/ex 0.005"), 0.006" in has less, 0.004.
I'll test 0.004" and measure compression with my tester.
Test before and after adjustment.
Compression of 220 +/- 5 PSI need higher octane. Light high speed pinging at WOT ca: 7000rpm. Engine has ca 2500rpm left of good power.
If compression will be significantly lower I'll test that. Overlap will increase with less lash.
Megacycle 125-60 has 0.004" lash, 125-70/75 0.005"
When 125-60/65 can so why not 125/70/75 in a street bike.
My ride after work:
Ramnäs- Engelsberg- Fagersta- Söderbärke- Smedjebacken- Säter- Hedemora- Norberg- Fagersta (refuel)- Norberg - Salbohed (kebab pick up)- SätraBrunn - Haraker (sunset photo)- Skultuna- home.
Photos at a few stops. I did not find a good stopping point in Söderbärke. A really nice small village that gives me old memories of how small villages looked like 40 years ago and before.
Ride stop at my favourite ride restaurant in Salbohed, kebab with fries to eat at home.
Photo stop in Haraker where sunset can look beautiful. This time at 7:15pm. This will be earlier and earlier.
I'll continue to stop for photos here. In October it will be dark around 6pm.
The auxiliary lamps my K6 got to 2023 are useful when dark. Reflexes beside the road will light up like a landing strip.
The stops need 360* photos to get the right feeling.
Kebab before it got the red spicy sauce and the milder creamy white.
A GT to help it down and relax.
8cl of my favourite Gin, Bombay Sapphire (blue as my K6).
Unfortunately only 40%, original 47.5% has a better sting. Not available here. Too fun not allowed

My juice need higher ethanol content, bikes and car less.













Edit:
Did the valve adjustment today. (Day after the ride)
Compression tests to start with.
212-220 PSI. Strange, lower than last time.
Checked valves. All in valve lashes were too tight. 0.004" 0.10mn feeler gauge did not fit!
0.002" 0.05mm had space though.
Ex were all 0.006" 0.15mm
Must have used wrong feeler gauge last time. All were equally set.
I always double check valve lash. Rotate crank a few revs more.
Adjusted all to 0.10mm (0.004")
Compression test again
Back to high numbers despite ex lash were reduced from 0.15 to 0.10mm.
In lash makes the biggest difference!
215-225PSI.
I'll see (hear) at next ride what happens during WOT reaching and passing 7000rpm, mostly 5th gear.
The little longer ex duration and lift might help.
Maybe I need to spice up the juice with octane booster for WOT rides.
Germany and Greece have 100 octane RON at the pumps. Maybe 102 too.
Another reason to move
