Diagnosing an engine and retuning a carb?

How about a link to one of those videos. You have it all backwards.

Here's a little tip that I would like to relate. Many fish bites if ya' got good bait. (Taj Mahal)

So that sound is normal then? It's just weird because my first engine didn't do it.

My Angle Fire PK80 howled like a Banshi, but the Zeda was much quieter. Quality is not something you can count on from these manufacturers.

Another thing that I did to quiet down the whine of the PK80 was to replace the ball bearings of the clutch basket. There was a lot of slop in the bearing and the clutch gear didn't mesh well with the drive gear. Replacing the cheap ones with high quality 3mm ball bearings made a big difference. The gears meshed much better and ran quieter.

To keep it simple you want a Milk chocolate spark plug like this, if its not milk chocolate you got a problem now if you got a picture of your spark plug i'm sure a dozen of people will tell you the exact thing weather it's rich or lean

Ps.. sometimes boobtube isn't the best thing for everything i mean crapberry is on there

Let the shame fest begin.

The last one is a picture of what I put in there in the meantime.

So just some background. This plug was a fresh plug, did 3 tanks of gas at 24:1 and did my first 32:1 the other day with about 9 miles on it.

FIrst two pictures you are def rich that plug shows more oil on it then a pimple face teenager

now the 3rd pic if thats a new plug clean it, then put it in the bike, and let the bike run idle for a bit and then ride around quarter throttle take a pic for later this will tell you if you need to move clip up or down

then clean it again this time drive around 1/2 to FULL throttle for a bit this time the plug should show a new sign if its rich then you need to jet

if you don't know weather your lean or rich at each just send pic

First two: Rich and way too much oil, probably due to break in, makes sense.

2nd: Not enough miles / time on it to be able to tell much of anything.

The BBR engine I bought had so much paint around the plug hole that it flaked off and fouled the plug.

 

[Cisco]

The NGK BP6HS plug you are using is a good choice, maybe a little on the hot side. I'm using one with a CNC head because the head can sink away a lot of heat. I'm using a B8HS in the Angle Fire head. During engine break-in I was running a 16:1 mix (super rich). There would always be a puddle of oil on the garage floor, oil dripping from the exhaust pipe. The plug would be oily and black too. When I switched to a 32:1 mix and raised the needle clip up a notch, it was like a different engine. It winds up high and clear sounding while accelerating or climbing.

Black or silver? I went with a silver one the second time after reading a thread about paint chips getting into the cylinder. I took my engine apart when I first got it and found metal specks on top of the piston

Even 24:1 was too much on the break in? I'm now doing 32:1 so I wonder what it will look like now

expand...So, I actually moved it to the third position if 1 was the flat end of the needle and 4 was the pointy end. I'm an idiot. I was convinced that lean was running with too much oil and rich was too much gas and I was wrong wrong wrong.

I'm going to move it back down to #2 and do what you said when I wake up tomorrow.

Best way to clean a spark plug or should I leave it as is? The cleaner plug was used for a quarter mile when I was running honestly 12-10:1. I was using an 8oz container of oil and was pouring based on the transparent markings on the side. Rookie mistake, been using a measuring cup ever since.
