How many Pistons do I have to ruin

[tripledog]

I think someone piston my corn flakes.

[Mr. Clean]

I think you will ruin 57 pistons.

I think you will ruin 57 pistons.

I wonder why you picked that number?

That has a nice ring to it. Kinda groovy too.

You guys must be pulling my crank.

This is probably my fault for assuming (against my better judgement) that everything in the carb was stock. Granted this 3 wheeler had less stupid/hack stuff done to it than stuff I usually buy

[tripledog]

I think you will ruin 57 pistons.

I think you are being overly optimistic.

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

[AK47KID]

I'd part the whole thing out and sell it and use that money to buy something better 2,3 or 4 wheels...

Verify the needle with what? What do I have to work with? Nothing. I got this machine not running. You're making a whole lot of assumptions, a lot of which is common sense stuff I addressed before ever making a thread.

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.

FYI, I did not force any crank bearings into the case.

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

The right side main shaft bearing is a "boutique" bearing commissioned by Honda and Yamaha. While the rest are readily available from bearing manufacturers, this one is not. Do some damn research before you post.

Boutique bearing? Did you pick it up when you were getting your nails done?

I was able to find EVERY transmission bearing on ebay except the clutch lifter bearing, and if I had that bearing in hand I bet I could find one. If they're on ebay, a bearing shop would have it or be able to get it. Do some damn research before you post.

The machine shop bored and honed the cylinder to size with the piston, in fact they ordered it for me, I never saw it until picking it up.

Good. Well then I guess one thing got done right , huh?

"Stock" jetting doesn't mean anything, especially on a 30 year old machine. Every machine is different for one, location (elevation, temperatures, humidity) have a lot to do with it.

Yea, it does. If it didn't matter why would they put it in the repair, oops! SERVICE manual then? It gives you a starting point Einstein. Use it. If you did a little damn research you'd know what you have for choices on jets. It didn't take me long to figure it out. Every machine/situation is different? No sh!t Sherlock! Captain Obvious would like to meet you.

Good luck on your Harley. It's dinosaur tech, so you shouldn't have a problem.

C'mon Princess, that's the best you got? The "Old Guy Insult"? Pansy! I've been called worse by better. Interestingly that transmission related dinosaur tech kicked your azz didn't it? Same tech that's be used in manual transmissions since well before you were born and is still in use today. But I'm sure you know your way around a tranny too doncha?

Edit: where are you even getting that I'm "dead set there's an air leak"? For the past two pages I've been saying I think it's the jetting.

Oh, I don't know.The droning on and on about the leak down testing maybe. Make sure your intake and exhaust connections, boots, etc, are good, do your pressure test to be sure, then figure out your jetting already.

Also, I've read through that whole jetting article on another site.

Maybe you should read it again?

If nothing else, you may get good at it. They say practice makes perfect.

now that is some fine tuning that might help you��

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

Enough of the needling, already. Whatever.

Exhaust manifold. I'm at work, so I'm working on it when I can. I know 9psi is high, haven't gone higher than that.

I drilled the end of a cow tank plug and put a truck valve stem in it, pumped it up with a bicycle pump. Air pressure gauge is out of the spark plug hole. Pumped it up to 7.5 psi (15 psi gauge) actually unhooked the pump. It has dropped maybe .5 psi in the past 4 minutes.

This is a significant air leak. Once you get the motor together, before you do anything to the carb, you need to throw your pressure tester back on and see where this leak is coming from. Spray soapy water on all your plugs and guage. If they're all holding air then you need to look at your carb boot, crank seals, head and base gaskets. Don't mess with anything until you do this. It's not optional, it's a must. Every thing you're saying is pointing to an air leak. 300 degrees is not even approaching overheating on an air cooled motor (I'm assuming this is an air cooled 250r, you never mentioned it in the thread). I repeat, leak test leak test leak test, and once again, leak test
