well another fun job getting high off fumes carb cleaning. anywho heres where im at i have the back doors open cleaning the jets/needles, the first two were dirty as ****, i remove the floats and pins - clean them with degreaser. and as for the jets i use carb cleaner and a compressor airline. i no the idler jets are usually them main culprit but all the jets were really dirty. intrestingly the 2nd two chamber were really clean. and looked like there jetted ( bigger holes in the needles ) i dont know why the guy i bought the bike from would only do two? but is this standard ? #1 and #2 the first two idler jets are clogged completly. i ususally use a twisty tie (like from a garbage bag to poke thru them then the compressor does the work.) but i cannot get a open hole on the idler jets. how can i clean them? how can i remove the idler jets?

 

They are about $6.55 a piece, buy some new ones. Not a huge expense.

 

Then how do you get them out? Why not simply remove them and soak them overnight in carb cleaner with the rest?

 

The Idle jet is the slow jet. It's got a slotted end so a well fitting slot screwdriver will remove them. If he's referring to the non removable ones. those are for the Starting/Choke circuit, and you can't remove them. Just have to work on them.

 

Ah... Got me confuzzled there too. I thought he was referring to the Choke circuit too. Which is why I went 'buh' on the replacement

 

whoa whoa. now im confused. ok so maybe we all can be on the same page: the one jet that i cant get unclogged is the one that does not have a slot or hex to remove(as oppose to the other two jets). so with that in mind, where can i go from there?

 

your first post you said you couldnt get a twistie tie to go through the holes. i had the same problem and realized there is 2 different twistie tie thicknesses. there are plastic coated ones, and paper coated ones. try using both. one is a bit smaller wire in the center.

 

the f3 has two different sized jets on the different carbs from the factory 135s on the outside, and 138s on the inside, so the center carbs should be bigger, so don't fiddle with them bud, I'm looking right at the copy of the service manual as I write this. The idle jets should all the the same 140s. So unless 138 means smaller, which I have no way of knowing, it's done right, if it does mean smaller, and anyone feel free to jump in and inform me, then your carbs were done backwards.

 

I think you need to look a little closer at the manual. The idle jets on page 5-2 are #40, not #140, and yes they are smaller, much smaller. The higher the number, the larger the hole.

If you can't get anything through one that doesn't have a screwdriver slot, then just keep working at it. I'm assuming that you're removing the paper/plastic from the twistie tie right ?

It should essentially look like this when done.

 

sorry, yeah, the slow jet is a #40, the main jets are 135 outside jets, and 138 inside jets, so the inside jets will be larger he DID NOT only jet two this the correct set up.
