Jetting Change

[f14rio]

I made a one clip change to lean out my fuel as I was going through fouled plugs every 20 minutes or so.

Can you guys tell me if the pictures of the spark plug look good? Before they were very wet and totally black. Now they are light and dry... I want to make sure that it isn't too lean...

Link not work dank? I didn't realize that I could just post the pics so I did that now and hopefully no link issues.

Well an update on this saga... as I noted in my first post that I made a clip change to lean it out, i then rode the bike for a good 30 minutes without issue. Took the pics that can be seen below. Plenty of crisp power except low end was kind of weak. Took it to the track today and my boy gets on it for no less than 2 minutes and the plug fouls!!

We are going to tear down the carb and clean it out and probably buy some new jets. Anybody have any advice?? I'm certainly no expert on this stuff... 1st time having 2 stroke bikes in 15-20 years

i am no expert either, this is my first bike period, and im 17, but what ive heard is that there supposed to have a light golden color, whereas yours look darkish on one side and kindof wet.

is that a fresh plug? color doesn't look bad , but the ground strap looks beat up. is the electrode still square - or are the edges rounding?

Yep fresh plug with about 30 minutes of time on it. Electrode is still square.

Funny thing is ... 24 hours later and 2 minutes into riding the plug fouls. Also... plenty of oil dripping from the exit of the silencer and runs the down the length of the pipe.

I am running 42:1 whereas the previous owner ran it at 32:1 without problems until recently.

I don't think I mentioned this earlier but it is a 125cc. Main jet is a 180 (manual says standard is 185). Got the clip on the needle on the 2nd notch from the top.

Any suggestions?
