Get proper gear, dont cheese out on a good helmet, goggle, boots.. this shit will save your life.
be ready to replace a few sets of levers and handle bars. DONOT be afraid of dropping that bike. its far tougher than you and it will survive.
No reason to be scared of it, just realize it can and will hurt you if YOU let it.
If its had fuel in it sitting for a few years, Carbs clogged.
edit (just realized something after typing all of this.) If its fuel injected them im a idiot for typing all this shit . LOL
Do not fear the carb clean. its incredibly easy, just a little scary the first couple times.
Hit autozone or orileys and get some barrymans B-12 (big ass aresol car, not that crappy dip shit) and a bag of 0000 steel wool.
Grab aprox 6" of stranded copper wire.
SAFETY GOGGLES!, B12 will burn your eyes right out of your skull. No bullshit here, be careful and
have the route to the sink or water hose planned.
If you get this shit in your eyes you will run around screaming like a little bitch and be blind for a few mins. Trust me I know....
but its the absolute best available for the job your about to do.
Pull that carb apart.
This is a important step. Pay specialy attention to it.
You idle screw on the side of the carb. turn out out carefully. COUNT the turns until the screw unthreads from the carb. Write it down.
The idle mixtre screw on same side but bown lower, just above the float bowl, Carefully and gently turn it IN and precisly count the turns, down to 1/8th turn! be PRECISE.
Write it down.
make sure your phillips screw briver fits the float bowl screws perfectly or you will strip them.
If needed some small channel locks can be used to grab them from the side and break them loose.
You will want to be especially careful with your flat head screw driver selection when removing the jets. make sure it fits the slot PERFECTLY.
If you need to grind it until it fits.
If you do not take this advice and the jets are over tightened by some maroon, you run the real risk of braking the ears off of it and then your fucked.
I have a handful of flat heads just to do carbs,
You will need a big and small flat head. big for main jet, small for the low speed jets. they are down in the carb.
Pull all the high and low speed jets out.
lift the slide and press the emulsion tube out with your finger. it may be alil tough, but you can do it.
Clean all of them with the B12 and the steel wool. make them as shiny new as you can.
I often chuck them into my drill and spin them slowly while squeezing the steel wool onto them to speed this process.
Use the stranded copper wire if needed to poke the gummed up fuel out of all the jets and passages on the emulsion tube.
Twist the wool up into a nice long point and slowly twist it into the jets.. give the jet a few good turns to polish the insides of them
make those things look like GOLD. the smoother and more polished they are, the longer it takes for them to gum up again.
Plus the carb just works infinatly better.
CLEAN CLEAN and MORE CLEAN.
spray through all the passages on the carb. no dribbly shit, the B12 will Blast through.
reassemble it. install. use the number of turns you wrote down to adjust your idle and mixture screws.
O shit, lost them.. Read on. dumbass,
most the slow speed jet on the lower side of the carb usually likes to be 1.75 through 2.5 turns out.
Do not crank it down tight, just gently bottom it then back it out 1.75 turns.
Once carb is on the bike. fire it up. it will idle wonky.
Let it fully warm up and then carefully turn the screw in .5 turns. and watch your tach. if no tach, do it by ear as best you can.
You wan to go up as high as it will go before sputtering. if it idles down, turn it out until highest idle is achieved. but no more than 2.5 turns from bottom.
wow I miss the old days of cleaning carbs every weekend..
wow Im all amped up again , like im about to out for a ride!
Good Luck!
