Yesterday I went for a test ride with sealed exhaust and new tyga reeds. Whent out for about 20 miles calmly and returned "with a big smile".
Now the engine pulls clean and nicely up to redline. My rear sprocket is 42T, so it can do this in 6th gear even with (slight) uphill. I tryed this for a couple of km, and calmed down. While still riding at high speed, not WOT, I noticed a sudden power loss. Grabbed the clutch and the engine stopped. Once the bike stopped on the side, it started at first kick, keptt idle OK. Continued running home calmly. Once I was relatively close, tested the engine again and it revved up OK.
Could it have seized? This bike has been a full day on a track less than 500 km ago...
