Thank you for the detail about what's happening inside the carb when you make different adjustments. Also very helpful info at the end about the alcohol, conditioners, and other stuff in gas. Great info!
always learn something when I watch your videos. Sometimes it’s something new while other times it’s a reminder of something I’ve forgotten. Today was only use booster that comes in a metal can.
Thank you for the very complete tutorial! The one circuit you missed in your cleaning was the enrichment circuit. I just ran into one that was clogged to the point that no fuel was being added but would increase the idle at start up and keep it running Every time I build a S&S "E" carb I tell people not to touch the throttle if the enrichener is on or they will foul the plugs. This was the one that the guy needed to pump the throttle to get it to start and stay running when cold
@@TatroMachine Not the inlet, the enrichener (choke.) The enrichener circuit emulsion tube was clogged. Had to run a small wire through it to clear it. Thanks for answering back!
Thanks for you carb tuning instructions it worked for my super G carb .For months i just couldn't get the carb tuned so I followed your instructions how to set the air/feul mixture screw an it was right on target my bike sounds good . Thank you so much good job 😀👍
@@TatroMachine hi Tatro I out together a Harley with 103 stock twin cam with super g carb and a thunderheart programmable ignition system the bike has stock pipes . What intermediate and main jet would you recommend i use thanks .
i have no idea because the gas you use is not what i use and every motor wants what it wants. get some jets and see what happens. you see me doing this in the videos all the time. tatro
throw the s&s G carb in the trash and get a smaller carb. yours is way to big. the hsr42 is best but the s&s E will work too. start with the jets that come in them and go from there. tatro
Hey Tatro you should do a video of a bare bones wiring diagram/install. DIY harness (headlight/ taillight only) There aren't any good videos like that on YT. Or anywhere that I can find. Just ordered motorcycle electrics pain free hope that helps me.
looks like theirs a bushing for the throttle shaft?, is it replaceable? or just replace the throttle shaft? i suppose thats probly why s&s sells a replacement body..or can you install an o-ring...any advice? it was sucking air enough to not let it idle down...thanks
Dude...how do you replace the butterfly? I don't recall how I got the durn thing apart. Now that I have the new parts here, I'm doing a rebuild and the butterfly is bigger than the doggone bore it sits in!
i have an stock 06 xl sportster which backfires when i leave the house soon after start up. should i let it warm up longer or should i troubleshoot it. and if t/s where do i start?
I have the same bike with 19K miles. Does a couple backfires if I don't keep the revs up when it's cold. Runs perfect except for that. I am going to get some injector cleaner like Tatro recommended. Also I have a little rust inside the gas tank at the plate where the gas nozzle goes in, not sure how to stop that.
The idle air mixture setting should be set with an approximate 25 rpm drop on the rich side of the peak idle adjusted rpm when tuning. Idle fuel/air mixture is negligible for any increased fuel mileage, except at short idle times; long idle times of an air cooled engine increases cylinder friction with increased temperature and shortens engine life. The idle fuel/air mixture setting has no purposeful function at open throttle positions. To truly "get the best mileage you want to get" with a carbureted engine, one should invest in an adjustable main jet, if the carburetor will accept it; adjust with a locked throttle at a desired constant cruise speed, set to a 100 rpm drop on the rich side. Fuel air mixture is constantly affected by elevation, temperature, humidity, barometer change, and manifold pressure (MAP); all of which affect the density of air or Mass Air Flow (MAF) into your engine. adjustable main jet settings should be performed periodically with any significant change of air density or when riding at a different continuous speed. When running the rich side of a peak rpm adjustment with about a 100 rpm drop, a slight amount of unburned fuel aids in cooling and lessons cylinder friction with reduced heat (too rich a mixture causes carbon build-up and fouling). Cylinder head temperature (CHT) will rise substantially with any rpm drop set to the lean side of peak and engine detonation will occur, this significantly shortens engine life and defeats any fuel economy gains. Generally speaking: If you have gray soot in your tail pipes you are running a good mixture, if the soot is black you are running too rich, and a chalky exhaust is indicative of too lean a mixture. An exhaust temperature gauge (EGT) is the easiest most accurate way to determine proper fuel air/mixture settings of an engine, by setting the temperature of the exhaust gas 100 degrees Fahrenheit on the rich side of peak rpm. EGT will continue to rise with an rpm drop on the lean side, until combustion becomes almost impossible.
Yeah forget that carburetor cleaner that's backyard stuff need to get a gallon can from Walmart AutoZone checkers the gal can carburetor dip cleaner take the carburetor completely apart make sure you remove all the o-rings anything plastic remove set them aside that comes with the basket put your parts in basket make sure you disassemble the whole carburetor put all parts in the basket play basket in the carburetor dip can do not leave these parts in the can longer than 30 minutes Max are your parts come out looking brand new take an air hose to everything if there's any residue carbon buildup still find yourself a paint gun cleaning kit what are the little tiny brushes clean out all the holes in your jets intermediate jet make sure your spray inject tube is clean that sits in your float bowl is sprays into your carburetor fake gun cleaning kit between all your carburetor parts take note scrapers or sandpaper memory cloth anything to that carburetor very delicate remember take the whole carburetor apart just down to the body of the carburetor and that's how you successfully clean the carburetor don't use carburetor spray cleaner brake clean any of those products is a carburetor dip can parts basket like 20-25 bucks 730 minutes on your part to clean without breaking your back standing over the counter trying to clean your parts by hand the only thing you're going to do is end up with a backache and still have dirty parts with massive scratches in your parts very delicate you are supposed to replace any part scratched damaged make sure you replace every o-ring Make sure you replace the carburetor wood spacer plate there's an o-ring on that wooden spacer and there's another o-ring on the carburetor the wooden plate o-ring goes towards the manifold and you can't adjust the carburetor if the air cleaner isn't on it s&s recommends having the air cleaner on the carburetor when adjusting the carburetor hopefully my information will help you even more don't throw your carburetor around on the table you can break something real easy watch out when you remove accelerator pump to replace it turn down your carburetor do it over a bowl frying pan a pot do the fact that if you aren't familiar with that carburetor he has a couple little o-rings in there that will need to be replaced and has the two little tiny ball bearings or somebody flips that off of there and they was barbarians go flying and you'll be looking for days for those stupid little ball bearings so be careful removing the accelerator pump I mean make sure you replace accelerator pump it's a little diaphragm the little tiny o-rings let the little ball bearings sit in so for the whole kit master rebuild kit for s&s super e s&s sells it for $120 the kit has everything you need replace everything inside that carburetor and outside master rebuild kit check it out s&s super rebuild kit don't let all these other people with these ads for $29.39 $50 for rebuild kit weather in Yonkers what they're

to have a shovel in it after I blew that to pieces in the middle of nowhere in Nevada for what it cost to rebuild the shovel I built me a s&s Big bore Evo that that hits140 mph barely turning the throttle I've never been able to open the throttle all the way the bike won't hold up to so remember bike seats longer than 30 days when you have an s&s carburetor you need to take a carburetor apart and you repeat the cleaning process that's what s&s requires look up locker in that carburetor and it gets all sticky don't think about cleaning it with a can of carburetor cleaner that doesn't work maybe for the final process of cleaning after you pull it out of a dip can and if you get some bad gas air leak or something getting a black residue real light start the bike warm it up take a spray bottle of warm water put it on mist give the bike some gas insert missing the water into the carburetor make sure you keep the bike running it will break down all the carbon up your vowels valve stems

Hey tatro just watched your latest vid, I have a 1993 evo and can’t get it to idle without backfiring and cutting out, it has a stock ignition timed correctly, an ev27 cam, 48 pilot jet, stock cv carb but polished inside, and ported heads that have probably been ported too far, why can’t I stop it back firing at idle and cutting out, idle set at 1000 roughly Thank you for any help, I only ask as a response to your latest vid.... Rob (uk)
I learned more in this video than I did in all 12 years of public school.
Best mechanical videos on TH-cam period!!!!! Guy Speight
Getting ready to rebuild my super E. So glad I saw your video. Your the man Tatro. Thanks for sharing
Your an awesome mechanic but you are a ball buster, HAHAHA
Enjoyed this lesson it sure helps to know as much as this man .
Nice explanation and an awesome guide on how to clean out an S&S carb!
Thank you for the detail about what's happening inside the carb when you make different adjustments. Also very helpful info at the end about the alcohol, conditioners, and other stuff in gas. Great info!
Great attitude by that fella who says: last guy was an idiot and didn’t know what he was doing…. Just repair the carb and shut it.
Very well explained with your whole thought process. Helped alot. Thanks so much
always learn something when I watch your videos. Sometimes it’s something new while other times it’s a reminder of something I’ve forgotten. Today was only use booster that comes in a metal can.

i just shake the float bowl. if it rattles, than the needle valve is go to do and the passage is not cloged up.

@@TatroMachine I use regular unleaded here in California I used premium but It made my bike idle rough .
throw the s&s G carb in the trash and get a smaller carb. yours is way to big. the hsr42 is best but the s&s E will work too. start with the jets that come in them and go from there.

Another good tutorial from over the pond. Thanks
I AM IMPRESSED
Hey Tatro you should do a video of a bare bones wiring diagram/install. DIY harness (headlight/ taillight only) There aren't any good videos like that on YT. Or anywhere that I can find. Just ordered motorcycle electrics pain free hope that helps me.
Thanks 👍👍
What jets should I use in this e s&s on 1964 flh with stock heads ?
Sat here enjoyed the education my super E awaits me good banter glad dumb ass had problems
Nice!
How do I get in touch with you, I’d like to get fly wheels balanced on a S&S 113 EVO . Motor was born 2001
looks like theirs a bushing for the throttle shaft?, is it replaceable? or just replace the throttle shaft? i suppose thats probly why s&s sells a replacement body..or can you install an o-ring...any advice? it was sucking air enough to not let it idle down...thanks
they do not come with bushings stock but s&s does sell them. you will have to machine the carb inorder to use them.
tatro
Is it me or is Tatro working on Dr. Steve Brule's bike? lol Guy sounds just like him. lol
Could someone tell me the exact dimensions of the "Pump cap oring" Part # 11-2371
Dude...how do you replace the butterfly? I don't recall how I got the durn thing apart. Now that I have the new parts here, I'm doing a rebuild and the butterfly is bigger than the doggone bore it sits in!
it fits in at an angle. you have to square it up in the bore and than tighten the lock screws. that is if you have the correct kit.
tatro
@@TatroMachine Thanks dude! I got it. Is there a trick or method for "winding" up these throttle return springs on either end of the butterfly shaft?
I got the throttle cable side.......its the other side I'm having a time with....
@@TatroMachine thanks for the help dude. 'preciate it.
I absolutely cannot get the butterfly to sit correctly and the brass rod supposed to go in only one way? I need help!!!
My idel screw moves by itself my idel is always dropping can you help
stretch the spring some.
tatro
@ 5:42 more than this person had trouble with getting that throttle return spring in place but it is do able .
a lot of people saying mikuni carb is way better than s & s super e . on a street driven bike which is better? 1991 fxr low rider ev 27 cam
hsr42 mikuni.

@@Alilretard1 i agree. its a cold start thing. i also like tatros idea of using stabil in every other tank.
it is lean. put more jet in it of fix the stupid computer.

i live in florida. is shipping tribodine gas additive cost prohibitive to send here? the t-shirts weren't. by the was t-shirts are excellent.
what do you think about the S&S carb is there one better
38 mm Mikuni VM is better for stock Sportsters
Good
Finally!
89 XLH1200, typical CV carb Super-E.....2 gallon tank produces 48 miles...why do I only get 24 MPG on the damn thing???
the jets are too big. start dropping them one size at a time untill you lose power and then go back up one size.
