Have not done that. It’s definitely next. Maybe it sat a while. I have no idea how to set float height though.

Updates!:
Got 45 minutes on a new plug. Definitely rich.

The needle says AJM. Quick google search says 017-414. Not sure what that means yet. More research needed. The clip was at the bottom. I moved it up one notch so the needle should go down and get leaner if I understand it.

Carb is a PWK S54AO JK
Jet sizes- 162 main, 35 pilot
Everything looks really clean in there. Didn’t see any kind of build up/deposits. Gas flows freely.

The bike will not start now. It does that deep popping sound a lot more now as well. It’s like it was in the worst part of Saturday. But now giving it a rest and coming back didn’t help. Wondering what I did that would make that worse. Just lowered the needle and put it back together.

[MEDIA=youtube]kmzpz7oZNQk[/MEDIA]

A video of what it sounds like. I bet someone with some knowledge will get some info from it. Definitely doesn’t sound right but I don’t know what it means.

I might just put the needle back up and ride this weekend. I’ll be at Hollister Friday and Saturday. Cooking in the near 100 degree temps. Ouch. Maybe on the Husaberg.

Unless y’all can help!! Thanks in advance.

From my experience, when you hear a different sound from the exhaust
when trying to start the bike. A kind of thump, pop, thud sound. It is
the exhaust flapper valve getting stuck from carbon build up.

When my EC300 did it. The bike would start and run, with reduced
power when taking off in low gears until you got the revs up then it
would take off. After a couple min. riding it corrected it's self and
returned to normal.

Maybe not your problem, but a possible answer.

Just watched the video.. The thudd...duuuduuu? sound at the end of the video
seemed more to me like the sound you get when you open the throttle too
much when kicking it over.

I know I sure don't like to start my GG's with a tennis shoe. I make sure I a
wearing a decent boot. And I am a bit more aggressive when when I put a smooth
kick through on the arm.. Don't do a quick snap kick down or you can / will damage
the internal starting gears or brake the arm.

Also only start it in neutral. Don't try and start it in gear with the clutch lever pulled.
From my experience it putts too much drag on the motor and won't turn over fast
enough.

Another thought.. You might want to look into getting one of the newer kick start
levers. The old stock ones were rather small and hard to get a good push through on. The one in my attached picture is the steel one from a mid
1990's GG Pampera 280. Much longer. Not sure if these are still available.
I got mine on E-bay or possibly from Jim Snell at Rising Sun. He is a trials
dealer in Indiana. Should be googleable.

My 2 cents.

Wow. That all makes so much sense. That’s exactly what happens is that sound when I give it too much throttle. Some throttle would make it start before. Now I get that sound. And that low power till it revs up and then running fine later rings true too. The tennis shoes make it hard, that’s for sure. And when I kick it sometimes I feel like the kickstart gear feels not great. Hope it’s not damaged. And the kick start lever is short! Especially compared to my dad’s xr650r.
Thanks man. This all good stuff. Learning a ton.

There is also a YZ250 lever that is supposed to work on our bikes.
Much cheaper and available. May have to search for it, or ask someone
on here what the part number and year YZ it is from.
Best of luck.

Oops found it:

Think I may have narrowed down the problem. I might be putting the float bowl on wrong. I don’t see how though. But I have gas flowing well out the fuel line. Tried it through the float valve and it flows great and the float shuts it off. Put the bowl back on and turn the gas on and it just drips out the drain plug at the bottom. Should flow nicely I think. So the float must be getting caught up on something. There’s a diagonal brass tube, presumably the overflow. That took me a while to figure out where it should go. Maybe it’s wrong but I can’t find a another way. Right now it’s going inside the u shaped float.

Seems like that diagonal overflow tube is going into the right place. The bowl goes on easily. Still no fuel flow though. I couldn’t even blow through the fuel intake with my mouth. Then I blew compressed air in, which I assumed would release a stuck float valve. After this I could blow air through with my mouth but no fuel flow still. I’m baffled by this. My new theory is that this is what was happening while I was riding before. The float wasn’t working quite right and every once in a while I’d suck the bowl dry and the bike would feel out of gas for a sec. Sometimes more than a sec. everything looks clean and new but maybe I just need new float components.
With the carb at 45 degrees the tang is just touching the plunger on the needle. Seems perfect.
