carb or spark?????

[Big Lou]

Yesterday worked good no plastic,quick run up road an back,all power no RIDE, jjust to see

 

Everything worked fine, id warmed it up.

 

Today, all plastic is on, go for a cruise, ,,no warm up,,,whole time acting like. Its flooding,diddnt see it for 10 miles, just picks another cylinder, ,didnt even miss it ,,so its cutting in an out,,,, lo ok at temp.its. still cold at 20 miles. Figure "ill warm it up",down shift,2 times to, third, at 4;000 And up all cylind,ers hit all the way to 9.000 ;;i now it sat 3m weeks for rebuild so i figured trash,

ran a cool 3 miles at 7, 8, an 9,000. Then slowed down to cruise, in 5th

 

Spitting,, back firing,,, so back up high rpm,an if i play with gas it is almost like ,,

the throttle is drowning the plugs,,

i set them at 35the. Book said 31. To 35

 

ILL TRY SEA FOAM TOMORROW,,,,,,,,,

 

Got in 50 Miles

I TRIED THE BLOW IT UP OR RUN OUT GARBAGE, EVEN PLAYED WITH CHOKE at high rpm no effect at all using choke,,all going down highway,,

 

What now?????????

Sea-Foam. Filter clean?

[Big Lou]

Never took off filter, got spares go check now,

pull plastic again, ,,,,,

 

Wonder sitting here if closing gap on plugs a little would help.

 

Dont want to do anything while its hot, i played with it in garage an fan came on first time all day,

 

I belive you when you say 110 IN THIRD, I PASSED SOMEBODY PLAYING WITH IT AN DONT KNOW WHAT COLOR IT WAS

[mbrood]

The plugs should be gapped to spec. This is matched to the coil and the specified resistances in the system.

 

The high RPM is controlled by the high speed needle, main air and fuel jets and the butterfly. The lower RPM is controlled by the idle mixture screw and the idle air and fuel jet... this goes from idle up to around 2K as the butterfly and main needle start contributing as throttle advances. The most classic problem is for the TINY fuel idle jet in the fuel bowl to get clogged requiring choke be used from idle to around 2k but would have almost no impact at the higher RPM. Separate out the response areas on your bike and you narrow down where to look.

 

I think the plastic (on or off) is a red herring... you fired her up and ran her through some paces... I would bet that a bit of grung broke loose or some dirt found it's way. Remember that the high speed jets are plenty fat and hard to clog.

[Big Lou]

Idle is great,,throttle response on stand is a little sluggish, ,will go straight to top of range if its hot,,,,

 

Since i cleaned all water system it dont heat up,,,its 88a degrees today,,,an it never heated enough for fan, or even got close, before i tore it apart,,,it ran in the middle, ,,of range

 

Now it runs on the low end an i cant get it hot,,,,

 

Just did gas filter, going in morning to get sea foam

 

If i run a 1/2 can to half tank, then same day run anonter tank wont that clean out fouling of plugs, i heard about

[pmelah]

half can to half tank should really clean it out good i have half can of berrymans b12 to full tank

[Big Lou]

never heard of berrymans , is it better,

 

I really like chevron injector cleaner,,blue bottle , dont know about using it on a bike

 

filter acted like it was clogged a little pours out gas from tank

slower stream from filter , gravity was the same . new filter now . get sea foam tomorrow....

 

AN DRIVE IT LIKE I STOLE IT

ITLL BE CLEAN OR DEAD, AN ILL REBUILD IT AGAIN

 

 

SHE SURE MOVES WHEN I SAY GO ..spitting or not

[Yammer Dan]

If you are having trouble just grab a can of BerryMan's and save a few bucks. Dump the whole can in a 1/2 tank let those carbs know you mean it.

Have you ever done a Sea-Foam soak? Later if this don't work we can try that. BerryMan's is a good cleaner just a little harsher than Sea-Foam and I don't like to use it all the time. But great for what I think you got going on. Dump the BerryMan's in run it enough to get it all thru system and leave it sit overnight.

BerryMan's at Wally World less than 4 bucks a can.Techron is another good one that Wally World has but more costly. BerryMan's is what I use for dirty carbs. Sea-Foam to keep it running right.

 

And you could loose a set of plugs with all the cleaners. I use AutoLite 4163's when I'm having problems. A lot cheaper if ya ruin them.

 

BerryMan's also has spray great for outside of carbs and any hole you can squirt it in on the carbs. KInd od like Sea-Foam Deep Creep.

[Big Lou]

it was running fine , little cold natured ,, never did spit and backfire. like it does now.

 

I WILL GET BOTH . RUN THE BERRYMANS ,, its an injector cleaner or listed as something else??????

 

i got a shrimp boil to go to saturday, and i cant go if this dont work . it has never been the money .it is the time !!!!!! ME LOVE SHRIMP

 

 

SPITTING, BUCKING , AN KICKING . PRECIOUS IS GOING ... IF I HAVE TO BE TRAILERED BACK .... I WILL NEVER HEAR THE END OF IT

 

there are two basic rules at this house "aint my problem"

the other is a five minute rule ,,,," if you lay something down for than five minutes, its been moved.put up,or thrown away......even the dog is in on it , took one of my zip locks with the bolts in it to the swing arm when i first started....

 

shrimp is 2 hours away,, will get plugs too thank you

[Yammer Dan]

Berry Man's close to Sea-Foam and other cleaners It is B-12

CHEMTOOL

Fuel Treatment

 

Red,white, blue & yellow can. They have a spray and a liquid.Spray great for cleaning outside and throats of carb and jets you can reach.

[Big Lou]

COOL WAY COOL

 

WILL GET IT ,

DIDNT KNOW BERRYMANS WAS B-12

 

ILL GET BOTH

:cool10::cool10::cool10:

[pmelah]

like Dan said its harsher but does the job good for 1 time use then go to sea foam on a regular treatment hopeful that will work for you i have a full tank and just put half a can of berrymans in let it mix for about 5 min then crank the bike and i let it run for 15 min to get the fuel into the carbs i shut it down and let it soak for 4 hrs. and just cranked it up again and ran it for another 15 min this time i had a quicker response out of the throttle now i will crank it one more time let it run for 15 min and then let it set overnight to do its job on the carbs tomorrow i will drive it lie i stole it with the new fuel filter in it the pump cleaned out it should run like a scalded raped ape :fingers-crossed-emo Boomer come get your pygmies they are feed now :rotf:

[Big Lou]

Sounds good

 

I will do that, ,needs to soak huh,,,,

i got 92 or 93 In it now,,i am going through talladega Sat, morn figured id get something stronger,

 

Other day i looked in piston hole an seen some black carbon on piston, ,,,it bgoing to get cleaned

 

 

I think i got some platinum plugs i was saving ,, if they fit, ill call about whether they are hotter or not, ,,

 

 

 

Thanks i will do the soak

[Big Lou]

Pulled plugs today,,,3 With an orange tint, one straight gray, all have no carbon build up at all

 

Put new filter, found a big one , in closet,,,now i can see gas filter, and dirt

changed mount for me, i dont want to carry a foot long screwdriver,,,lot of gas stations here have bad gas,,,its the country

 

 

Put in berrymans, 1/2 can to 1/2 tank,,

cranked it up,,throttle would kill it, ,,cold

 

Warm, it will jump, ,,run it for 20 minutes, with me sitting on it shaking it back and fort trying to shake cleaner into gas

 

Just off,idle, at 1100; itll miss a little

1300 Rpm and up its fairly smooth,,,,,little air horn sure does suck air,,

 

Seems to me a bigger hole would help it run

 

Goosed it, an choke it down at air horn horn, now let it set for 4 hrs like you say

 

 

Is the air horn really suppose to point toward driver,, if it was pointed front would it get more air?????

[Flyinfool]

It gets all of the air it needs. If you do something to increase air you will have to rejet the carbs or it will run lean.

[pmelah]

Dont cut holes in breather cap like flyin fool said it gets all it needs

A number of us have tried opening air box up and it does not make it better. It drastically kills any throttle response 2500 rpm & above. Loosen top of air box and put a very thin shim in so lid won't close all the way. This will allow more air to come in. Try reving motor or a very short ride.

 

Picture is of correct air box orientation.

[Big Lou]

MINE is defenitely on right ,,,when it backfired it came out the little hole

 

got some attention

 

 

i was on it !!!!!!no shirt!!!!!! glad my gas tank top dont leak going now to do my 4 hr warm up like I was told

[Big Lou]

so just finished warm up second time ,, revves great ,, didnt back fire but once

 

 

i live on dirt road an think "seems to me i did this allready"

so its idleing great ,, purring like a kitten

 

i took a small rubber hammer an just barely tapped each carb,,

3 no problem

 

very front left , it cut off, started it back up

 

it spitting an sputtering ,,NO IDLE , have to give it gas to stay running

 

finally smoothed out , did it again

 

died,,,,hard to start

 

waited ,, cracked gas started ,, revved the dog out of it an alternately put my hand over breather to SUCK trash hopefully,,, died 3 times sucking trash,,,, it was spitting an sputtering bucking an kicking,,,

 

got to save starter, ,, got almost idle back to fine before i quit ,,, put rest of can in started it again and run a minute then choked it out an left it

shrimp is sunday so tomorrow is last day to fix THIS

[pmelah]

You pronably go.a have to do a seafoam carb soak yammer.dan would know mor than I do im jist staring to learn the ins and outs of these bikes the hard way

[pmelah]

Or could ne just.needing a good carb synce I dont know
