T140v - Triumph Bonneville T140 Basic Carb Balancing 6mins. 

You're very welcome!

Glad to hear that!

If you want to use manometers then you will need to disconnect the balance pipe between the carbs. Use two manometers, one on each carb individually to balance your carbs for fine tuning. I doubt you will improve on the performance however. Lots of effort for very little reward in my opinion. On Honda fours using manometers is the only way to do it, but on these old twins its very easy. You must still do the mechanical part as I explained on the video first to set up your cables and carb stops. After this just fine tune with the idle air screw to get the best rpm. Hope this is of use.

Yes they are a bit easier to set up, but you still have to set them up correctly down at the carb end as advised. If you don't you will chase yourself around trying to tune your carbs correctly.

The old ways are often the best. As long as there both the same diameter rod around 5mm then it will work perfectly.

If you have mk1 Amals then yes the tickler works fine on its own. Remember to remove the choke slides and blank off the top of the carb top. You can buy brass blanks from Amal to do that. I just use a stainless cap head screw with an o ring to form a seal and held in with a bit of silicone. The fumes will rot away the silicone over time but it lasts more than a few years so its no issue. Hope this is of use.

You're welcome!

As advised this the initial stage of tuning only to set up your carbs. This video allows you to set the idle point of your lifters on both carbs correctly and your throttle cables. After this you move into carb fuel air mixture tuning which is completely separate item. If you don't get this bit correct you will never get the mixture tuning correct and will chase yourself around trying to get it set correct as the carbs have a link pipe. Using a vacuum gauge allows you to get the fuel air mixture draw set over each lifter and is great to get the airscrew set up correctly at idle, but it becomes un balanced again as soon as you open the throttles as the lifters are at different gaps if that makes sense for you.. For instance you can say have one carb at 3mm lifter gap and the other at 5mm gap, and then using the air jet open it more to compensate for the lower gap on that lifter by drawing more air in via the air port on the idle mixture port at the front of the carb. That works but at idle only. As soon you open the throttle every thing will then run weak on the 3mm side after you move into the other jets operational areas as the lifter is lower on that side allowing less air to pass over it . You must remember that air gets into the carb via the lifter and the idle air inlet port at the front of the carb. You can read a full write up if you look on the Amal web site of how that all works for now. The idle mixture is only a part of a big subject, as the carb operates differently dependant on the position of the throttle. Different jets come into play at different points or load on the engine. I will make a separate video to explain all this when I get time. Hope you find this of use.

You can for tuning. This vid is for setting the mechanical parts up. If you dont get this bit correct you will never get the carbs to work correctly.
