Since today was really nice weather and there was close in Hohenschwangau a vintage car and motorcycle meeting, I took first my lovely smooth BSA A7 and cruised there to see what was going on ..... then back home and changed the A7 (my bread and butter bike) with the SQ4.
What a difference! The Ariel went off like a beast loud and gruff, but very inspiring. So I drove the about 20 mls with 60-70 mls/h ... I made my show there and came back after 3 h and about 50 mls in total with bright eyes and a bright smile.
Conclusion: was the best test run so far, still to do some fine(-st) tuning of the carb - the transition areas are not as gentle as desired, will do this after changing some gaskets and the needle. But all in all a great and hot ride - the oil filter was really warm too. But even in town traffic the SQ4 works fine. Have checked the spark plugs afterwards, all had the right color!
Compared with the A7 I had to improve the seating position (slightly higher for me) and the battery box pushes me on the calf.
Because the third gear was a bit louder than the others, I recently changed/refilled the transmission oil (SAE 50). There are now some minor leaks on the kick starter and on the shift lever axis and underneath at the speedometer drive, also on the primary chain case .
Now consider whether I should switch to semi fluid grease.
But how many goes in the gearbox
Happy biking Rudy
