howmuch does a carb sync run for

[timebombprod]

anyone have an idea of what the price should be for a carb sync? i did order the carbtune but it still hasnt been sent at all, and i could use the money, and time itll take to get here. i know i just need to call for a quote but also i dont wanna overpay, when i rode bmx i called 2 shops to lace a rear wheel. one said $60, and one said $30, i went to the one that charged $30 and they did just fine, way better than i did i kept warping the rim at the last few spoke patterns.

i know in the longrun a tool for myself may be alot better but im thinking about right now because i cant just plan i need to get things sorted. not just with the bike.

I’m confused. Why are you asking how much does it run for if you say you ordered one? Of course it takes time to arrive as it is coming from England, not your OReillys on the corner.

Old bikes cost money to maintain; if you are having budget issues, maybe it should sit and wait until you can afford to take care of it.

For example, my daughter's bike has a very troubling problem where it cuts out when coming up to a stop light. All carbs have been cleaned, synch'd and vacuum lines checked but we still cannot figure out the issue. One thought we have is to replace the intake boots again but that does cost money my daughter doesn't have. Instead of me giving her the money, I have chosen to ensure my bikes are operational. Consequently, she has decided to wait until she can afford it which hopefully will be later this summer after she starts her new job. Budgeting and planning for your expenses far enough out in advance will give you the best idea of when to buy something and when to just sit and be patient. It's hard I agree but it will be worth it in the end

If you have the tool on the way, why not do it yourself? There's plenty of YouTube videos on how to do it and believe me, it's not at all difficult once you understand the basics.

I have no idea what a shop would charge for that, but I guarantee it will be much more than you paid for the carbtune. I'd say it is likely you won't even be able to find a shop willing to do a carb sync on a 1982 motorcycle, let alone for a decent price.

yes, it is partially a budget thing, but the reason i was seeing about this is that a carb sync is really the last thing i need other than getting the front brake put back together, and it says itll take about 5 weeks, so i was just like crap i gotta wait 5 weeks, one thing i will say is i shouldve knew with an older machine comes plenty of fixes and some hard to find parts and alot of time.

Carb sync is important for best performance but if the bike is running "good enough" you shouldn't let that keep you from riding it. There's plenty of folks that'll try to convince you otherwise from trying but a home made sync tool can be made for peanuts, mine is two plastic pop bottles and some tubing. Get that brake done and give your project a spin, being a first timer you're probably going to discover things you overlooked anyhow that will require more attention.

5 weeks for a Carbtune?
Where did you order it from?
Mine came in 5 days -England- Oregon

COVID-19.... most likely a lot of disruption. There certainly is on international cargo.

You can get it running & ride it on a good bench sync until it arrives.

yes, its because of covid-19, and ill have to give the homemade one a shot for now im sure itll make it better than what it is now. the reason i dont know about riding with how its setup now is because itll climb revs to about 2k when all 4 cylinders run so i didnt want to accidentally take off too fast or something like that while riding, being new and all. did get to ride a dirt bike the other day made sure to do some u-turns and try to get some good balance going around the field.

 

[Who Dat?]

Did you rebuild the carbs or were they done professionally?

If you did them, I can't say how the bench sync was done.

If you had them done professionally, there is also no guarantee.

If one of the members here did them, I'd say they are pretty close, so run them until you get your Carbtune.

If it’s climbing to 2000 rpm without the choke then you have the idle set too high or the throttle cable isn’t adjusted properly. You have forum members in your neck of the woods (Earlfor and GSRick to name two); have you reached out to them for help?

bench synch should be plenty to get it running well enough to ride.

 

[salty_monk]

Put pennies (or something) under the slides & adjust them till they are all the same. Wind the idle stop back until you just see a crack of light under slides.

Adjust idle stop to 1100-1500 after it's warm...

Go ride...

Couldn't it also be an air leak?

gs steve cleaned the carbs so i have no doubt its not his error, my idle is set at 1100 but when i rev itll go to about 2000, then eventually drop, my bike is also running on 2 cylinders at 1100 rpm, it runs on 1 and 2 but 3 and 4 arent working right away, and knowing how the carbs get tuned together it seems like they need adjusting. i could also not be getting enough fuel in cylinder 3 and 4 so i gotta check the fuel level. the throttle cable is fine and i did replace the intake o rings so i shouldnt have a cable or leak issue, i will check for leaks just to make sure. also i had it idle at 1500 for chuck to see if all 4 cylinders will work at that rpm, and while my engine didnt sound like a rotary, i still dont think all 4 were running together, but eventually it picked up in rpms after they warmed up i assume.

The problems you are describing will not go away with a carb sync. You have air leaks or the pilot circuit is too weak. Steve would have done a bench sync on your carbs & I heard him say he sets the screw to 3 turns out which should be quite rich for standard equipment. With that said I would think an airleak is the most likely issue.

 

[LAB3]

To help clarify the air leak issue, you need to also be sure of a good seal all the way from the cover of the airbox to the inlet of the carbs. On mine, I really need to take the time to make sure the rubber tubes that connect the carb throat to the airbox are in the proper position to create a good seal.

Following!this seems like a very interesting thread

Can someone explain to me how a bot like this profits, or even exacts revenge on anyone?

 

[timebombprod]

why wouldnt the cylinders work at 1100rpm then 2 out of 4 will heat up, i get the issue of it rising but what if its not getting enough fuel to the 2, and its sucking in more air cuasing it to work a bit but not what it needs, so when it gets a certain amount of fuel flown to it, it rises up in rpm.
