I was reading another post and seen this COLORTUNE thing used to check the idle flame. Anyone ever tried it? How does it work? Can you buy them here in the states? :?:

Something that takes the place of the spark plug. How can you look down into the cylinder? I can't find much info on the net... :(

www.carbtune.com
 
I've only heard good about them, but I don't have one.(yet) They are kind of pricey.... First you pull a plug and install the Colourtune, they are basically a window into your cylinder, its glass with an electrode that you hook the plug wire up to, so you can adjust the fuel mixture burn visually....it's like looking at a oxy-acetylene gas torch, too yellow till you bring in the oxygen and get that nice blue burn going
 
Looks like $67 + S&H from the British Isles. Prolly take a month to get it... 8O
 
Remember that the plugthread on the GS is not the same as on cars.

I have two of them used them in the past on a double carburettor car, but can't use them on the bike because of the different plugthread.

They worked fine on the car, you can really see the color change as you adjust the carbs.
 
Actually I too was looking into this colortune there is even a review of it right here http://www.thegsresources.com/_forum/viewtopic.php?t=26723&highlight=colortune

To Kz, there are different sizes of colortune or perhaps its just adapters most cares is like 14mm but the colortune also has 12mm and 10mm I think the bike is 10.

I own another product they sell called Morgans Carbtune II I wonder if this colortune would even make the carbtune nessessary

:EDIT: the bike is 12 MM

You can buy the same kit directly from the manufacturer for ~$52 shipped to your door. The $65 price is for the motorcycle kit, whereas the $50 price is for the car kit.

I have the Carbtune II and think it is well worth the price. I couldn't imagine trying to tune the carbs one at a time or with a mercury-based system.

As for Colortune, I've been considering it, but haven't pulled the trigger yet.

My mercury sticks are easy as pie to use. The only disadvantage is storing them and moving them around. I could never travel with them because they have to stay upright at all times. But as far as using at home, the mercury are as good as any other.
 
Does the Carbtune II give you the perfect gas air combo? I would think even though the carbs are in sync that you could still have a lean or rich plug, no?
 
What is the differance from the one for cars versus the one for motorcycles? The one for cars is 12mm and is 10 Euros cheaper.
 
I have both the Colortune and the CarbtuneII. I bought the Carbtune on the recommendation of Jojo after I had two (2) mercury carb syncs leak all over my garage floor. I love the Carbtune II.

The Colortune is pretty cool, but I don't think it is necessary. If you adjust the mixture for max rpms, you can tune almost as well as with the Colortune. At least, that is my opinion.

As for ordering from England, I highly recommend them. They are very nice and the delivery is not much longer than regular post here in the states.

From the Carbtune website - "What's the difference between the car Colortune and the one for motorcycles? The motorcycle Colortune has a plug so compact it virtually guarantees the compression ratio of even the smallest cylinder.

Check it out - http://www.carbtune.com/index.html

Terry,

I have read a lot of topics about carb adjust, but I still do not understand how can I adjust the mixture for max rpms.
Can you explain me about this?

Thanks. :D

Adjust the mixture screw very slowly and listen to the engine. Watch the tach at the same time and adjust until you get the highest rpms. You should be able to see it in the tach and hear the engine running faster. After adjusting the first carb, go to the next and do the same until you get all four adjusted for the highest rpm.

I'm no expert on carbs, but this seems to work. If you pay attention to what earlfor and Keith Krause say about carbs, you'll get excellent information.

Colortune & CarbtuneII

Colortune & CarbtuneII

I have both units, and found them great. The Colortune allows you to easily visualize what is happening inside the cylinder. It is especially useful when you are unfamiliar with descriptions such as "tuning for max rpms", or have a carburetor that someone else has gibbled for you. It would also be a great tool for those trying to re-jet carburetors after airbox or exhaust modifications. From my experience, it would allow you to complate in five minutes tasks that could take hours or days; ther is no need to "get a plug reading", adjust heat ranges, query spark gap or coil operation, or guess jetting. Were I in the business, I'd consider buying a set of four, just to ease adjustment of motors.

The Carbtune is useful for all the reasons mentioned in other posts. One benefit I appreciate is it's mobility, I can share with friends.

I too would recommend both colortune and carbtune, definatley takes the guess work out of setting up the carbs.

I got mine from http://www.carbtune.comI think they are based in Ireland but delivery was great.
 
I just ordered both the carbtune and colortune with the carbtune pouch and carb adjust tool. It was a little pricey, about 101 pounds or about 200 dollars, but I figure it will save me alot of time tuning.

I ordered straight from the website listed in the previous post.
 
200 smackers.. damn, I hope it helps you out alot Pano.

Let us know how it goes
