86 VT700 Carb Removal

sorry if this has been addressed in the past.

I just bought an 86 VT700 won't start so I need to remove the carbs for a rebuild. I don't have the manual yet so if anyone has photos and instructions i would appreciate it.

thanks

86 VT700 Carb Removal

thanks for the quick reply and excellent suggestions.

I will say that i really did try the search feature, but unlike other forums that search internally, the google search throws me outside of this forum to another window with more than I want...did I do the search incorrectly. btw it did not come up with the post you pointed me to.

I must be doing something wrong in my search???

Use the "Search" that's in the blue bar at the top, under the "HondaShadow Discussion Forum" title. The Google search is just there for show, and is really just a distraction from the forum's internal search feature.

How to remove carbs from 1986 VT700C?

Wow...Search button is really small and kind of hidden. I agree, the Google Search bar takes over the page visually.

but thanks for all the help on this.

BTW> I did find that using wire ties to hold the folded up tubes was a big help when re-installing the carbs. I actually removed the upper tubes, wire tied them in the "socks rolled up" configuration, this gave me an extra 1/2 inch of room for the install. The upper tubes went back in easier than I thought.

Now to sync the carbs....hoping there is a post on the, will be using the new found "search" button

again thanks

Look up "manometer"

That's a gauge that a lot of us build out of about $3 in parts to sync the carbs. They work great!

86 VT700 Carb Removal

I came up short on doing a search for carb sync or balancing on this forum.

but I do have gauges from my Nighthawk days, and pulled the Air Cutoff hoses, and used those ports on the carbs for my adjustment...actually the carbs were very close.

BUT...still have major performance issues...Starts/idles fine...Just NO POWER at all. it just bogs and falls down under any throttle, basically un-rideable.

I just did a full carb cleaning (lot's of experience with my Nighthawks) with my supersized Ultrasonic cleaner, so I know the carbs are very clean.

It does act like it is not getting enough gas, wondering if the aftermarket fuel pump the PO put on could be the problem.

any ideas?

if i should start another thread on this extended subject please let me know.

thanks

Might want to start another thread to be sure to get more input, but I'll start off by saying that you should test your fuel flow by disconnecting the hose form the fuel pump to the carbs (at the carb side), turn on the ignition, and click the kill switch on and off a few times. You should get a burst of fuel with every click. if you have that, you know it's not a fuel feed problem.

Second, be sure there is absolutely no binding in the carb slides. If they have resistance, the vacuum inside won't be enough to lift them so the engine will be fuel starved.

Third, check for vacuum leaks. It's east to do on this bike since the boots have to be folded and twisted to get the carbs off. it's easy to not get them sealed well and that will make your bike too lean also.

Fourth, what is your ambient temperature, and how well does it start with and without the choke? My bike is stock all around and even at 85 degree air temperatures, I still have to use the choke to get it reliably started. Others with this same bike will say the same thing. If yours is stock and behaving differently than that, it might get you on the right track.
