All,
I need to clean the carbs and either need someone to come help me thru it OR I come to someone and someone do it...LOL
I usually do all my own work, but carbs and I don't seem to get along.... Long story......
Anyone in the area fit the bill? I have a fridge full of beer!!!!!!!! and a full Bar!!!!!!
I would also be willing to push a little cash along to help if necessary.....
I just hate to take it to a stealer and get hosed for $400 to $600 when I can do 80% of the work myself...and not be happy with the work or have the bike tied up for a week....
Thanks in advance,
Brad

Brad,
Have you tried techron? If it's clogged jets, I would try that first before disassembling.
I'd be glad to help, but now is not a good time for me.

Like skinhead said, try running cleaner first.
I just pulled my carbs off to fix a fuel leak... I can answer questions on how to get them out of the bike, but I haven't actually dissasembled the carbs, I only needed to remove and seperate them.
You should start out by ordering intake o-rings, carb kit, and fuel leak kit (if its not part of carb kit) from redeye.
If you haven't done the desmog, I would recommend getting that from redeye as well. There will be fewer parts to put back together after the desmog is complete.
It was my first time, so it took me part of 6 days over a couple weeks to get through it. Take lots of pictures. They will come in handy.
You will need to take off the engine hangers. And unmount the coils, all of them, so you can move them out of the way. It's still a tight squeeze, but the whole carb bank will come out.

What specifically is the problem you are trying to address?

Brad, Techron is good stuff, but I recommend Berryman B12 Chemtool.
I've used both and B12 works as least as good at cleaning out the jets, but the kicker is that it costs about $4.50 a can.
Also check the rubber carb to airbox mounting screws (all 12).
Good luck

Okay, Hers the story....
Got the bike June of 10.... had some pop and burble out of the right exhaust...
At first I checked all the vacuum lines and carb connections... were loose, seemed to help, but still some popping..... Then the bike got wrecked and spent the winter putting it back together, but was all cosmetic.
next season, 11, I had issue with the petcock... fixed that... still some popping, almost like a miss, but not bad...
last year popping got worse, did a full Desmog, changed intake o rings, and had another issue with petcock.. same as before hole in diaphragm, so I switched to it to full manual and eliminated the vacuum line... so ther are no vaccum lines on the bike and all new caps on the intakes.
End of last year, still not right so ran Seafoam on the last 2 tanks.. no real improvement.. On the way home from my last big trip in September,I stopped at the shop that had worked on the bike after the wreck- well they just made sure it was mechanically right after the wreck so I was okay to keep it and not give it back to the insurance co. and he said it was carbs and would be $400 or more to fix, but he was sure it was carbs. It was American Wing in Wayne. I have used them before when I had my wing and had good luck,but I have heard some negative things since then.
This year, still idling rough and rough all the way up to 3500 rpm... enough to feel it in the handlebars.....even after 2 cans of Seafoam.
So far this year, I have run thru one full bottle of Techtron to a tank of gas and just did another yesterday to a full tank..... still idling rough, and popping and possibly missing on the right side.....
Also pulled the plugs and changed em out 2 weeks ago... all were nice and toasty brown... none of them fouled or even different from the rest..... kept the old ones as spares. So its most likely not ignition issues.... if one cylinder was not firing,the plug should show signs..right?
SOOO... I have a feeling that this Techtron treatment probably won't work... Will ride today and see, but not thinking it will..... And I don't want to let it go too long into the season and have the bike down in prime riding time.. even though it has been very nice these last few days, I just need to bite the bullet and get em cleaned out.....
So thats my story and I'm sticking to it...
Brad

I would keep the speeds low (engine speed <2500 rpm) 1 or 2 hr ride, let sit over night or longer, then another long slow ride, and repeat a few times to see if there is any improvement before tearing into the carbs. It sounds like a vacuum leak, even though you desmogged, so I would check ALL the clamps on the intake runners (remove the chrome covers on the carb linkage and get the one just below the carb, and while your at it check that the intake runner nuts are not loose. Popping can also be caused by loose exhaust header nuts.
Good luck and keep us posted.

Thats what I have been doing, but I really dont want to fuss with the carbs...
So I will give it a bit more time and recheck for vacuum leaks.....
Maybe when we are both out we can meet up and you can look Her over and see what you think...
Thanks all for the advice and will keep ya'll posted...
Brad

Or swing by the house, I can take a quick look, just can't do a carb teardown right now. I've never done one before and it's always nice to work out the kinks on someone else's bike!!  |

Pooping can also be caused by loose exhaust header nuts.
Skinhead, remind me not to follow too close to your bike... I would hate to be behind you when your exhaust header nuts are loose... |

Can't say as I blame you Al. You know what they say, if you're not the lead dog, the view is always the same.

Im sure you have but maybe take a look at the intake runner (chrome tube) screws (think there are 18 in total) to be certain they are tight....they tend to get loose over time and can cause popping and probably reduced gas mileage (I'm guessing on this part)
Do a search for intake runner screws and look for posts by Chrisj CMA.....his posts will have
a better explanation that mine....I checked my top 6 a couple of years ago and they were all loose....you experience may be different but it's an easy check....
Good luck !

I have checked them all ... Also when I had the tank off last , I used a small mirror to check the back side of the air box tubes to make sure they were seated correctly on the top of the carbs.....
And all the header nuts are tight.. with a torque wrench.....
But I will be looking at all of that stuff this weekend again......
Thats why I am pretty sure its down to the carbs....
