High copper and lead - am hoping it's the rivets from the spring plate as I read that this can start happening at around 25k. Will check soon.
18,252 Changed right after buying, so unknown mileage or oil. Looked terrible - tons of fine metal but no big chunks on magnet. Drive belt was overtightened when I got the bike.
19,305 This with Formula+. Moderate amount of fine metal, some on magnet, I don't like seeing more than this.
Between these two, changed mostly at 1k with Formula+, except once trying SYN3 (was slower shifting). Changing frequently hoping to see the amount of metal drop.
25,581 This with Formula+.
26,957 This is with Bel-Ray Sport Transmission Fluid. Drained oil looked better than in past, but there was a little foam on inside of the derby cover. I guess I couldn't see the high copper because it doesn't reflect as much light. I'm sure the Bel-Ray didn't cause the high copper and lead. Clutch and shifting seemed the same as the Formula+, but in the end it seemed like it may have been grinding on shifts a barely detectable amount in higher gears, but may have been me getting lazy about pulling in the clutch all the way. We'll see.
