carb adj

[N0tac0p]

the manual does not do the carb adjustment justice.  I want to verify how far out my jet's are, ie are they set at the 1.75 or 2.25 or......?  really can't see location by the pics in the manual.

also some have said they made the very adjustments above?  is that due to different main jets or...?

The adjustment is under the center of the carb all the way next to the intake. If you changed the slows to 38 then the recommendation is 1.75 if stock then 2.25  sorry

I think 1.75 is with stock exhaust and 2.25 is with nonrestrictive exhaust pipes. 
I think the 38 jets and nonrestrictive exhaust pipes would would require only 1.75

Keep in mind all these setups can be different, don't ask why they just are.

Search subject line Jets for Dummies  I believe there is a pilot jet picture and lots of good info.

reason i wsa thinking about checking is, it seems that i get that "rich" exhaust smell most the time.  i men thing runs like a champ ( i don't check mileage), get very little popping (no desmog), but i just wonder...

I think Robert meant to say slow jets. Stock slows are 35s many of us change to 38s. The pilot screws needs to be adjusted if a change is made.

what does the 38 vs 35 do?

Use more gas!

The reason for the 38's is for less chance of gumming up due to crappy gas.  The 38's have a larger opening than the 35's.

It appears some people feel it's not needed to change them, but I found it solved my problem of ruff runnning I had some years ago.  I went through every concievable problem first (the list is large)before I bit the bullet, pulled the carbs (again), changed out the 35's to 38's and smiled again. 

Because I'm either cheap or stupid or both , I tried cleaning the 35's first and when that didn't solve my problem, I went though everything else, then went to the 38's.

I pretty much lost most of that riding season because of my stubbornness and the girl just wasn't running right.

[N0tac0p]

losing it!!!!  can someone post a pic or fiche pointing to the screw that i am suppoed to check/adjust to 2.25 turns out?

the fiche i looked at appears to have the jets "inside" the bowl and therefore not the ones to adjust, but then i don't "SEE" the one i should?

again only due to getting a rich exhaust smell (unless thats common) when backing up or sitting at  a stop do i want to even verify

riders next to me notice it as well

Here is where the Pilot adjustment screw is:



I have my interstate carbs apart and have replaced all o-rings and dipped each carb in Berryman's carb cleaner and now have all six ready to go back on the rails and in the bike.  I had ran the 38's slow jets and found out (my opinion) that with 1.75 turns out that the carbs are still way too rich.  I am going back to stock in both my bikes and 2.25 turns out.  If you want 38's I will have two sets available... Not worth the money or the time.  If you go through the carbs and keep fresh gas in your bike your jets will be fine. Again, to each there own but I don't see the benefits.

thx.  looks to be fun.  doesn't look like i can get there with everything all assembled

With my new to me 2000 STD., I just changed all the intake o-rings while I had the tank and air box off doing a desmog.  This Valkyrie runs better than any of the other 4 I've had and it had the carbs rebuilt right before I bought it.  Checked the pilot adjustment screws and they were 1.5 turns out.  I turned them out to 1.75 turns to see if it would improve performance and all it did was give me that too rich exhaust smell.  Running Cobra 6x6s with baffles and K&N air filter w/prefilter.  If you have 38s in your carbs, try 1.5 turns and see how it runs.

I was lucky enough to get stude31 to work on my carbs a couple of months ago and I must say that after dicken with them for over a year this is the first time I can ride my bike and trust it to take me anywhere. He did a fine job of working on every carb and replacing O-rings and gaskets. The bike runs great now. Thanks Joe.   P.S. He even let me watch.

[stude31]

Thanks Rick for your kind words.  I must say that the bike is back together and fuel economy is in the mid 30's compared to the mid 20's I was getting. No rich fuel smell like I was and you can click the start button and it fires right up. Will be going through the tourer carbs next.
