Gas Leaking from the carbs

[dbdragracing]

Just purchased a Banshee and it runs great, but I noticed after I put it in the garage today that there was some gas dripping from one of the carbs...its coming from the line on the bottom that dumps out right in front of the swing arm...any ideas? Thanks.

might just need to clean the carbs outor get a new gasket kit

My brand new Shee did that at higher altitudes until I dialed the jetting to where it needs to be at.

 

Also if you are running 32:1 ratio rich fuel mixtures will cause that as well.

My first experience with a Banshee caused me to be embarrased at teh dealership for following the owners manual when mixing fuel.

Oh well stupid me.

 

I bought one of the carb syncronizer tools shown on the Video section of the Banshee HQ forum and dialed the carbs in sync and got the fuel mixture and idle set perfectly.

Wow how easy it was and wow what a difference.

 

I checked the Banshee after running about 500 yards at full throttle and shutting off the key switch and on / off swith after depressing the clutch lever before it idled down.

I took off my plugs and observed them and noticed that with each run and smaller jet at the higher altitudes I was at, the closer to a perfect setting I was at.

 

I have read that I am to have a slight brownish coloration to the plug ends instead of black or oily appearance. i believe this is the correct color but I cannot be absolutely correct on this. Each year I usually re-check this and check my books for accuracy.

No matter how many times I do these steps I allways re-check everything in the Manual.

 

I would think that checking these things will or should eliminate the problems you mention.

 

Other diagnostics besides your carb adjustments would include, overheating problems.

If your Banshee is older then, have the radiater cap pressure checked.

Try some Engine Ice in the radiater, or some Water Wetter additive.

This should drop the high temps some.

 

I would say that now you should have a good idea on where to start and get a feel of what symptoms you have.

 

These tests and adjustments are not all inclusive but rather a starting point for a good go at it.

 

The clymer manual has a few troubleshooting proceedures as well.

There is a manual here on this site that you may reference as well.

Good luck.

its also common or banshee carbs to leak if the bike has not been used over along period of time

what he said the floats will get stuck rip those little hores off ad clean them and check the float hight

Please disregard my earlier plug check as this was too vague and not used for ideal conditions.

Below should give you a more exacting way to do the plug checks:

 

Plug checking proceedure for correct jetting:

 

1. Go to an open area where you have at least 200 yards of free space to ride in a straight line at wide open throttle. Install brand new plugs when you get into position.

 

2. Run through every gear at wide open throttle.

 

3. In 6th gear at wide open throttle, pull in the clutch handle, and hit the kill switch and stop.

 

4. Switch back to the old plugs and place the right plug in the right pocket and left plug in the left pocket. Ride back to the house or trailer.

 

5. When you get back to your garage, get a dremil tool with a cutting blade on it and cut at teh base of each plug near teh second thread from the base near the sealing washer. You want to cut it down through the metal only. There is a ceramic base underneath so be careful only to remove the meatl threaded portion only.

 

6. Finish cutting the second plug as well the same way.

Look at teh band of coloration down at the point around the ceramic base. If it is black or oily , it is too rich.

If it is tan, it indicates a very lean condition.

It should be a light chocolate color for good jetting.

 

I hope this more detailed proceedure helps.

I dont know why your getting jetting suggestions when your float is just a little out of adjustment. Or it could be a dirty needle valve thats letting the fuel leak out. So,go ahead and pull the carbs off and check the float heights.Then while your in there,pull the needle valve and clean thoroghly. If your bike is running shitty,then move on to the jetting.Take a look at your plugs to see how shee is running.Good luck!

Thanks for the help.
