The 81-84 250r Oem stator plate is adjustable.I set mine at a degree or 2 advanced.I have advanced it all the way before for drag racing with 110 octane gas klotz oil .

Been a while since I have built an 82, but I don't remember the stator plates being adjustable. I may be wrong and it wouldn't be the first time. Regardless, the fact that it is adjustable I wouldn't be messing with it until you get solid numbers in other areas such as compression and squish.

He looks like someone who works at Smart & Final.

Not touching the timing. I don't have much knowledge about how timing affects how an engine runs and how to tune it. I may throw a slightly smaller main in and run a couple of plug chops later.

Well mydidn't realize I had the needle up a clip. Was going to try the 145 main but swapped the needle out for the richer one and took it for a spin, after figuring out why it wouldn't idle or barely run (plug was fouled.) Absolute shreddage, with the ITP holeshots it slides like butter too. So much better then the chinese balloons.
Pulled the plug again and it's black, not oily. But with the way it ran I feel like I'm at the edge and probably too lean with my riding style (read: WFO). Either I misplaced my 160 main or the guys at JSR ran off with it, and I know I'm missing a needle too. Not doing any real riding yet. ALSO considering the fact that I ran it for a bit before I blew it up with a 140 main in it, and it was about 50 out to boot. I put the 155 in for now so I can run some tests.
I would like to take this to the lake this weekend. Yaegerbro if your plans involve going there I'll be sure to hit you up. Otherwise, gonna try and do some tuning tonight and hopefully at least run this tank of fuel through it.
Edit: it won't rev out with the 155. Took it for a short (mile ish) ride to my house and it read at 240...? I remember when I really fried it it was reading 300+ going down the road, usually reads cooler when there's air moving over it. The plug looks charcoal all the way down. But I feel like it's still lean, which doesn't make sense since it runs so hot

Plug chops are more accurate if you run leaded gas. Pump gas will be sooty.
I never had luck jetting the stock carb on an 82...it ALWAYS ran better with the stock jetting even riding at 10,000ft.
Where are you getting the 240 temp? From the jug? exhaust?
BTW, The timing is adjustable on the 82. Be careful.

Usually get it around the head gasket area, where I can aim it right in there between the fins. At this point I may end up just buying a new carb, it's said to run better with a second or third gen carb.

I have very limited experience with air cooled motors, but I don't see how 240 is hot. I'm assuming you're using a temp gun on the head? On a liquid cooled bike the temp is read from the liguid, the top of the head will be 30-40 degrees hotter than the liguid reading. And the modern 4 strokes are running 230-240 degrees liquid temp. Can anyone tell us what an air fooler operating temp is? Why do you think it's lean?Well my

Looking for a Bassani silencer for a 2nd gen tecate, the style with the movable mount. 1st gen will work

Just as I thought. 240 is barely warmed up on that bike.

Well it runs really good, and that time I had something that ran really good it completely DESTROYED the motor when it detonated itself to death. Like there were little blocks of aluminum on the head and piston from the detonation. Complete roach of a KX250 but it pulled the front up in 4th without much effort. Lol.
I don't have anything to base actual temps off. I know it was pretty hot when I fried the last piston. I also know air cooled 4 strokes get hot AF.
