Looking good or lean?
>>
>>28876419
did you put it in, crank it for one revolution then pull it out?
>>
You have to at least turn it the car on, dude.

I will now hijack this thread for my own question.
>2stroke, 32:1 premix
>Using 93 pump gas
>spark plug is grey (not brown like everyone says) and a little yellow
Why is it grey and not brown?

Do either of you even know what a plug chop is?
>>
>>28876490
Nigga it looks like you didn't even turn your car on. Take the hint.

do you know what a plug chop is? you forgot the chop part.
>>
90% of the plug chop tuning I've done is on 2 stroke, small engines. The other 10% is a variety of everything else. If I pulled the plug and it looked like that.... I would be horrified at how lean it was; and on a high performance engine would have already cracked the piston.

No one knows what a plug chop is.. including me

You can't even plug chop.
lean, you want to have more brown.
I've re-jetted carbs on the roadside based on plug chops.
Bloody children, you wern't there man. ;)
>>
>>28876529
I'm too poor to waste spark plugs like that.
>>
>>28876585
You put the plugs back in and change the mixture dummy.
Clearance, Clarence.... Roger, Roger.

>>28876588
No there is something I remember hearing that they actually cut open the spark plug or some stupid shit like that.

you're supposed to put a brand new spark plug in, run the engine at high rpms for few minutes, then take the plug out and chop off the metal so you can see the whole insulator. it's a really dumb way to see if you're running too rich or too lean.

I hate boomers so much
>>
>>28876593
A plug chop is run the engine at high rpm under load then cut the engine.
Take the plugs out and inspect them.
Anyone that thinks you dismember a plug ought to be taken out and shot.

He's trolling. It's called a chop because you chop the throttle and kill the ignition, not because you physically chop the plug.

>>28876494
It's on a bike but I assure you I did turn it on. I suspected it might be lean but wanted a second opinion.

>>28876537
It's on a stage one 2003 Sportster 883. Looks like I'm going to have to ditch the 90° ram air intake and go to a more normal one. I figured this might happen but like some wise person on reddit once said, you can't truly know the limits until you've abraded them with your own flesh. Had to see for myself. There's a lot of noise out there.

>>28876674
If I had more money I absolutely would, data logging with throttle position and a wideband and such is absolutely the right way to do it, but for my budget and my purposes this will get me close enough.

Thanks for the replies guys. Here's the bike I'm doing it on.

How about a 250cc V8. Is that more your, just fit a thingy to it, mindset. ;)

>>28876728
It would make more sense to weld an o2 bung to the exhaust on that than on your tiny engine, yes.

>engine would have already cracked the piston.
I have a couple of melted pistons in the collection. One is from a four stroke.

Breaker points ignition lol I'm not sure if this is whimsical or cursed. What is this from?

If you pull your head out of your ass, you'd know that nobody uses a dedicated camera anymore, you just use your phone. I'm not going to pull the pictures off of my phone and then on to my desktop and then upload them to the same website just because it bothers people like you for no discernible reason.

Also if you don't know how to read a spark plug, that's okay, it's not a necessary skill for most people, but that doesn't mean it's witchcraft. Here's another one from a different bike.

I demonstratably ride and wrench, and start a thread that probably informed at least one anon about what a plug chop is and how to utilize it, and I'm the villain because I post from my phone? Would you rather this spot in the catalog be taken by a frogposting doomer or another EV engagement bait thread?

Look inside yourself anon. Specifically your ass. It is you who is gay.

I would say that is a happy bunny.
