I'm using the Digi Sync to set my carbs.. Problem is I can get all of them around 195 on the meter except number 3 which is the base carb . It runs about 240 to 250....
carbs rebuilt , intake O-rings , fuel lines , exhaust gaskets , valves adj , timing checked , compression test... all ok....    Cry

I'm open to all suggestions...

ignore the numbers.  Match all the others to #3.  #3 is NOT adjustable that is the baseline cylinder.  As long as they are all the same as #3 you are synched.

As Paladin said #3 is non adjustable . But I don't know why it would be that high. Something is not right. I would start by removing and checking the diaphragm on #3.

What's wrong is that the #3 carburetor is shut down (@idle) and the engine is running on only the other five cylinders at idle.

The manual is an irreplaceable help, especially in this area. Easy to fathom you are without the manual.

cooldude reading the manual should almost always be the best course of action.

It's not my first rodeo ... I have a manual , no help...  I know #3 is a fixed carb.  It still has a high reading when you bring the RPM's up ( 3000 rpms )  Carbs have been apart 3 times and even switch internal parts with another one , same results...  

PS: can't get any of them to come up to #3

A little harsh there Ricky.....and rather condescending to boot, that crap we can do without. You don't know TJ's background, I do. There's little he can't do on these bikes, including opening the case itself. That doesn't mean he...or you in your omniscience...have all the answers. His dilemma is a bit strange and if it were my bike I'd be asking for suggestions as well. Suggestions only, not caustic remarks....COWBOY. FWIW....that crummy manual is the same one I have, often referred to as the "Honda shop manual" and not the Clymers(your ridiculous remark "easy to fathom you are without the manual"). How foolish! As for the 3k rpm, where did it say he was trying to adjust/sync them at that rpm?

My suggestion young man; either keep it civil or keep it to yourself.

I'm not a fan of Ricky-D myself. I could do without condescending jerks on tech forums. Give useful advice without being judgemental or shut the hell up. We're tired of your crap.

OK guys, don't get me wrong on this. Ricky at times has had some good advice to offer and I'm sure it was appreciated by whomever received it. It's the delivery demonstrated above that we can do without....it's not necessary, not needed, not acceptable. We can all benefit from the experience of others on here, we don't benefit from the attitude displayed. Now, moving on........  cooldude

Just a thought and you may have already tried it: Have you tried hooking #3 up to a different line on the Digisync?

Completed valve adjustment wondering if the previous owner rejected when installing the 6x6.I didn't replace the copper intake gaskets because truck stacks are next In thinking I have a minor exhaust leak.

DWBD, I know you have some unorthodox ideas about the Valkyrie. 60psi, no carb synch, no carb work at all, valve adjustments every 20k, etc. Are you sure you know what you are doing ? That bike sounds terrible ! An incorrect valve adjustment can do some serious damage.  coolsmiley

I agree, something isn't right. The exhaust sound at the beginning sounds like a helicopter going over. As for the 60PSI, as I stated earlier....waaay too much pressure to be safe. Your contact patch most likely isn't any bigger than running a 200/60-16 bike tire....if that big.

I know what I'm doing,just bought the bike,previous owner bought it at 15 k mileage 5 years ago I bought it with 20 k for $2500.tires have a dot code of 0901..this bike has been sitting 17 years.
Carbs are the last adjustment..everyone does them first...for some odd reason.

I don't care about the contact patch,I don't want to have to remove my exhaust,bags etc every year buying MC tires at $200 a pop.My original Valkyrie had been serviced by me for 20 years and runs like a clock.What do you guys care if I run my tire at 60 psi? Ever try it?

Just for comparison. Our bikes sound different.

Because I don't believe there is a tire out there that has a MANUFACTURE posted Max PSI that high. NO ONE should go higher than the max recommended cold tire pressure from the manufacture.

Can it be done, sure, but when you post something that the greatest majority of people would not do, then you should expect people to reply accordingly. Just like a CT and flaming death.

Semi tires are 110 psi because the weight of the vehicle determines heat and pressure.

Weight of a motorcycle is 750 pounds.
Weight of car ,3500 pounds.
Car tires are made to support the added weight.
Would you overload a car then lower the air pressure or would you increase the air pressure to support the load?
Sorry know it all..I don't care what the sidewall says,Ive been riding 15 years at 60 psi.

Only 15 yrs....is that all? I've been riding over 60 years and still don't profess to know it all, contrary to the tone some of your posts exhibit. As for increasing the pressure to support the load, you're partially correct. If you were increasing the load on the Valk by quite a few hundred pounds, to increase the load enough to demand 60PSI would put the Valk well beyond it's design capacity. Your expertise is well documented by the comment you made; "I don't care what the sidewall says."

Keep in mind, members come to this site looking for suggestions, insight, methods of repair, etc., based on the experience of others. If a member posts something they have done that's controversial, so be it, but it's likely to garner some comments and suggestions based on that experience. The Valk won't begin carry the same load a custom built bike with a V-10 mounted in it will carry, yet that same custom won't be running with 60PSI in either tire. FWIW, I've seen two of them. 

With that....I'm done! Ride safe!  cooldude

I hesitate  to continue with this reply, but obviously you are still not understanding. My replies are not meant to be a method of synchronizing the carburetors. My replies are only meant to inform you, to show you, how to solve your problem of not being able to synchronize your carburetors. Your resistance to suggestions, and to help, is is easily recognized and noted.

Ricky is there any pleasing you?
Way I read it TJ read your post and applied it and still cannot get them sorted.
He has a problem and you continue to belittle him, not his problem your thoughts do not work in his case.
By previous posts he knows very well what he is doing but has run into a oddball situation.
Please be constructive or just don't post

Just so you all will know, I've talked to TJ recently and he now has it under control. I won't go into details, suffice it to say it has been adjusted to a maximum of 2 pts. separation, a better setting than I can get with my TwinMax.

I understand that this thread has been seriously sidetracked a couple times, and I also understand why you would not want to continue with it. I for one am interested in your situation, and how you sorted it out. For the others that wish to learn, is it possible to let us know what it was, and what was needed to remedy it?

If you do not wish to do so here, please send me a PM.
