'81 cafe RE-build from Qc - Noobie

Hey guys ! The newbie here again ! So i've decide to do a little build thread for my bike since there's more to do than I tought when buying this xs 400 !

The story :

I bought this bike roughly about 1 month ago, tried it before buying it and it was riding all good ! No issue for the first week.
After one week with the bike in the garage the bike didn't wanted to start anymore


I'm a newbie in the motorcycle world ! I've already learn A LOT of things from here and we the help of people here, thanks guys.

SO here's the bike :



What I've done to it :
Valve adjustment
Changed couple of rubber parts as the grommet olding the side panels
pretty much it as for now !

Things to do at the moment :
Oil changed ( But the bike wont start so i can't warm up the oil)
Front brake cable to shorten
Make the bike run
Find a kickstart
Install new exhaust wrap
Cranckcase cover gasket
Get uni pods Filter and probably a retting.
Install new spark plug (Iridium as recommended by Chris)

 

Video of the bike last time it was running (Starting problem, i had to old the throttle to keep it alive and make it start)



And there's a video after valves adjustment !



Bike was running and 1 week later ( Now, it don't want to start at all)

 

Update :

Removed the carbs today, and took them apart to clean em.
The inside was looking good, nothing major to clean.

But what do I need to check exclatly when cleaning carbs ?

I'm planning on getting unis pod filter so I guess I should jets the carbs right now as they are already apart ! What jets are recommenced to fit with UNI !?

Thanks guys, couple picture here :

Tell me what you think about th inside of the carbs

BTW picture are before i cleaned anything !

 

I think the problem isn't the cabrs but it's more of a spark problem. I've ordered new spark plug wires, cap and plugs since the previous owner didn't put the same caps on both sides ( one is 5 ohms resistance and the other have none)

Thanks for the reply

 

Thanks for the reply chris. Im gonna make sure everything is clean then! And is there any how to video ? Of what to check ? The main and pilot , the bottom hole and what else ?

 

Allright i'm gonne give it a try ! I didn't know that i had to take them ALL aparts.

 

Update :

I've decided to clean my tank using cider vinegar .
I've let it for one day and there's what came out of there :




I decided to let it sit for another day and see if it needs more thant that ! I've use a clothe to filter the vinegar and then reused it.

 

Yep !

Just went through a little problem I wasn't able to unscrew the pilot jet on one sied ! And I've heard a lot of scary story about them being stripped in there ! Any suggestion ?

 

Little update !
After 2 weeks with the vinegar in the tank there's still sh*t coming out of there


This week mail call :


And i've take the carburator all aparts to clean them weel like Chris told me to do and this wasn't a bad idea !



And can anyone help with this :



¸I don't know if i have to remove them to clean or not but i wasn't able to do so. Since i didnt want to use force on these

 

Question :

Hey guys the newbie again with question, again.

When i bought my bike there was no kickstart lever on it and today i try to get the boss out (The boss was there but not the lever) and when i tried to spin the boss with visegrip the boss was not turning to it's original position. It was spinning freely and wasn't doing anything !

So what could it be ? Should i be concerned about this problem ?


And here's my gas filter !



Should i change it or there's a way to get that crap out of there !?!
