Im glad i can correct you i wasnt the one who overfilled it, the last owner did. Oil in the machine now is on leven when measured warm. But you defo could be right about oil in the carbs, we'll see tommorow

Alright so i found out that intake boots are separated. Which i guess is not normal, this could explain the weird behavior of it running with choke, because more of more/false air. I ordered new ones.

yep, that would explain.... got to say that never saw manifolds de-laminate so badly..... go for originals, not alibaba stuff, such a nice bike deserves it!

Shade tree mechanic on the job
 

So, part 2 of Post # 10 above from under the shade tree might be the gremlin:

"2) One would start, run fine until hot, then pop/fart and die. Would not re-start until it cooled down - problem solved with new intake manifold(s) - the old one was warped, so it was not simply replacing the rubber O rings and patching cracked plastic around the outside."


That is one nasty looking manifold...am surprised motorbike would even start. Hope the new ones do the trick, and save your right knee.

Hi Pannekoek, if you don't want to wait weeks for aliexpress, you can order replacement here (dutch site)

https://www.uitlaatstore.nl/yamaha-x...grubbers-xt600

It's where I got mine from

haha, im suprised how well the bike ran when driving home, it was missing some power.

I decided to order from ali because it saves good money which i dont have a lot of right now, and i've got other modes of transportation. Usually to the netherlands it takes 10-15 days which is ok

Here we are, back again.

Carb Boots replaced. Managed to start it with the choke on, pushed in the choke, turned off. never got it started again....

Starting to really get annoyed by this motorcycle.... :(
Strange thing is, with the choke in, the idle ran like normal and steady.
Pulled the plug to check and it was soaking wet as well.

Don't think it's likely i'll buy a kickstart bike anytime soon...

See, told you there was a reason it was only 800 euro :)


Jokes aside, you are not so clear:


"Strange thing is, with the choke in, the idle ran like normal and steady."


Choke PUSHED in, means the choke is OFF



or "choke IN" meaning it's on?


If it floods the plug like that it could be that choke doesnt really close the passage, i.e. not really OFF.



Also, i hope the previous owner wasnt trying to correct the problem of the boots with a bigger jet or other idiocy.


Last, we need to hope that you put it all back right after your boots and carb clean, it could be some silly mistake in reassembly that will be hard to help you find through forum posts.



Annoying after only a few weeks? you still dont know what suffering for your moto means :)

Im glad to say again, i dont think its a nugget.

With the choke engaged somewhat, i was actually able to drive it.
And when it drives, its quite good! Plenty power, pulls well.

Air filter is pretty oily because of the fall sometime 3 weeks ago.

About the last owner, yeah he was a bit of a nugget so it might be a good idea to look into that, it could be to rich, or to lean. I dont know.

Lets not forgot it drove fine with stock settings before i got it home, so something must have happened. Or yeah he could have put in a bigger jet to combat the broken boots.

Here's a vid of her running with my hand on the throttle, trying to be steady

if the filter is a foam one, then oil is no problem, they are made to work oily



if the filter is the original paper one and it is contaminated with oil , then the oil could be disturbing the air passage making you run rich


if its paper filter, try to remove it and see if it helps.

Keep on kicking
 

Ouch, my right knee hurts just reading your XT tale!!


I'm out of ideas.


I could get one to start by spraying WD 40 straight into the air cleaner housing rather than using the choke....and after it started and warmed up it would start without the choke.



Keep on kicking, you at least knows it runs.

Well guys, nothing worse that could have happened. it got stolen:frown:
It wasn't insured for theft, because i thougt. well who's gonna steal an old bike. And i was just able to drive it...

Maybe it'll come back to you, if not, Plan B
 

Well, that really sucks.


Where are you?


I've a Plan B - if you're interested, I've a 1982 XT550 with only a couple of thousand miles on it that I will donate to you to replace your lost XT600. Has USA title, pretty clean and very low miles. Been in dry storage for 20 years, engine turns over. It's a kick starter, so you're familiar with the b****.


It's located in Denver, Colorado, USA, dry storage.


PM me and we can chat if interested.


In the meantime, maybe yours will come back to you after the thief realizes he can't get it running.



I'm like you, mine's not insured for theft, as I believe it'd be a fool who would even want to steal it....but after six motorbike rides around the globe and over a million miles on motorbikes, I learned the world is filled with fools.

If the air filter is oily, first take it out and try to ride it, see how it goes. I've seen air filters that were "a bit oily" stop the bike from running at all well. They're supposed to be "slightly damp" with oil, not dripping! Squeeze the filter as hard as you can, several times, and wipe excess off with a rag and it's right.

WTF!? thats really bizzare! Dont feel bad about not insuring, none of my old bikes are insured for theft, just not worth it, even if you find someone willing to insure you.


The only bike I dont like to leave outside without a heavy chain is the 1986 BMW R80G/S, as these have now stupid high prices and i know it can attract attention... but the rest of my 80' bikes? I never worry about them.


try to post about it in some dutch forums like www.motor-forum.nl with pics of the bike.
