I did my first test day in my new (to me) lo206 kart today after being out of 2 strokes for a few years.
It was on and off drizzling and raining, and I had one slide that took me off track through a puddle in the grass, but nothing seemed damaged and the kart kept running fine. Total running today was a bit less than an hour.
Regardless, when I got home, I drained the oil as I figured there was a decent chance that some water might have gotten in it.
When I drained it, I noticed the magnetic drain plug had some metallic buildup (probably pea-sized, no pics unfortunately). There was also maybe some metallic streaks in the oil, but that could’ve been lighting or water, was hard to tell. I had just cleaned the plug and changed oil (using 4T) before this weekend as well, as the kart had sat in the PO’s garage all winter. When I did the previous oil change I also noticed the pea-sized metallic buildup. PO raced it a handful of times by the sound of it and used 4T as well.
So my question: How much metal buildup is “normal” on these engines? Is this common? I get that pretty much any metal shavings in an engine is not great, just trying to understand what is considered acceptable and if I need to start saving for a new short block!
