How many Pistons do I have to ruin

[Scootertrash]

Since the threads already gone to ... I'm gonna turn this needle down with a drill and emery cloth. Worst I can do is ruin the needle or sieze the top end again... Lol

It just keeps gettin better!

Well, I found 1 NOS needle on ebay. Not sure if it would work for your trike tho. YOU'D have to do some damn research to figure that out. Then you would know what you were dealing with needle-wise. The needle is WAY cheaper than a piston.


You said the bearing didn't fit properly even after heating the case and cooling the bearing, so you used a dead blow

NOS needle? You do realize you can buy brand new Keihin needles right? Even a brand new carb, the same model that was used on these trikes.

I made a lot of assumptions, obviously assuming that the jetting was anything close to useable on a trike that I bought in non-running condition was not the best of them.

It was not a crank bearing. Forcing that bearing in was not in any way ideal, I was stumped with what to do at the time, and already stressed out enough over other things. Again, my mistake, no sense in calling me out on it now. Transmission is put together as it should be, thrust washers in the correct places, shifts through all the gears. I do have my doubts about it, using a bearing that is not OEM for one, not replacing every bearing with a brand new one, shift forks with irregular wear due to past mistakes, etc.

I mentioned it before, I already bought 3 different sized needles ranging from rich to lean. Going to use that as a starting point before i do anything else. Everyone in this thread kept pushing pressure testing is why I was posting about it, FYI.

Nono, it didn't run when I bought it. Every time I've torn it back apart it wasn't because it didn't stop running.

You guys have no faith.

No it's still a basket case.

I don't know if this has any bearing or not, but that's AK47KID's thread. You better keep a firm grip on your rod tho

My thread? What thread? This thread?

I had Faith. She wasn't as good as the ad on bathroom wall lead me to believe. Also, she was blind. And what's the deal with the pasties, anyway?

You maybe getting close to needing--Subtitles.

By the looks of the piston...you have a 4 corner seizure.

Look up the causes.

Man, I have absolutely refrained from posting in this, because it seems like anything that is said either A) goes completely into the I Know everything, Ignore category or
B) is an absolute attempt at derailing a thread further into the caticasim of confusion and uselessness.
If barnett had stumbled into this it would have been 128 pages by now. I guess so far, this is the only positive this had going for it.
Now having interjected my worthless smart ass comments and opinions...

I have assmebled too many engines to count, cars, cycles atvs 2 strokes and 4 strokes.
I have never, I repeat never had to hook up a bunch of leak down crap....ever
If you dont know the symptoms of a vacumm leak by the way the machine runs, you probably should not be building engines, plain and simple. And to be honest, when is assembled correctly, step by step of the service manual, not by opinions of internet sepculation, using the proper tools, there is about a .000002 % chance you would ever have a air leak.

Now I have fought issues that are straight up crazy, and asked questions to knowledgeable people, and took the info, applied it, and learned something, either good or bad. There are issues out there, that some just need to find just one guy, that had the same problem, that was so isolated that only the internet could tie the same 2 incidents together. That is not the deal here. This is only thread number 6 million of piston seize on the internet....

It is a 4 corner piston sieze here. (6 MILLION AN 1) This is not that friggin complicated.
So now, for my internet expert assessment based off pics and thread content....

A)There is a clearance isssue with the bore
B) owner is impatient and not taking proper steps to break in the piston and jug before it siezes
C) jetting needs to be put back to.....well see my signature.....and if it only runs for 10 minutes, there can be no jetting adjustments in 10 minutes and is all speculation at this point...
D) all the above...

Choose wisely...this for all the marbles.

Seriously though, if I came to a forum, posted being pigheaded stubborn for suggestions, as a assisting member I would have stopped giving advice on page 3....out of pure sanity. ..
Ever answer has been posted here. Every possible scenario for this guy's problem has been layed out in this thread. If it does not get corrected, the answer as to why is painfully obvious.

If I came to a forum, and ran into derailing comments, for my problem, I would shut the friggin monitor down and get out there and figure out my problem on my own, like we had to in the old days when there was no internet to go to, and a undying need and want to ride, over trumped useless hours pissing back and forth on the internet. ...But somehow I feel this will go on at least 4 more pages before it goes good, or gets worse....Please prove me wrong.

Garbage thread. Here's an idea, there should be a special place here for this type of garbage so it doesn't taint the rest of the site.
