Can some one tell me how to make a carb adjustment tool. Unless I mis-understood I think I saw where some one had made one from parts they bought off the shelf.

are you talking about the YICS tool?

will it work on my xj650h (1980)? It's not a YICS.

Are you trying to build a carb-synchronizing tool?.

"Eurica" Thats the one. How can I make one of those?

Eureka take a look at the 4th post.

like this
they work best if the water doesn't freeze

The Manometer is the one I was refering to.
Thanks for the help.

I wouldn't make one with water or oil unless you have a lot of room and make it 10' tall, otherwise you will end up with the liquid getting sucked into the carbs.

Yeah it sounds like a good idea but sometimes it is better to go with the REAL thing.
You can use guages or a liguid filled manometer.

Making your own is fine if you want to play games.

I use mercury manometers (that requires a certain amount of responsibility for the environment and safety)

Sometimes good old tried and true is the best, at least for me.

ArizonaSteve - you can get around that problem by making what is essentially a bottle bong. The vacuum hose is never in the liquid, however, the balancing hoses between the bottles are. This means that the liquid moves from one bottle to another based on the vacuum levels. When the liquid stops moving you're balanced. This type of system works the best for two carb setups... you can do both at once and it is very accuate.

The real deal is going to be smaller, more accurate, and require less fiddling to get it working properly... and it is a one time purchase that you can use on any of your future bikes (unless you get a SEI 750... :D)

I'm considering building a four bottle setup - mostly for the fun of it...

I'd like to see this bottle setup your referring to Woot. Post a pic or two would you?

Liquid won't get sucked into the carb as they are connected after the carbs.

You are unlikely to have it happen anyway unless you are not paying attention. If it moves too fast then the kill switch is your friend.

Even if it does, any oil will vaporise with the fuel on combustion with the only side affect as a bit of smoke out the pipes.

We've all put a teaspoon of oil down there before to do a wet compression test, the amount of oil in the oil manometer is not much different.

As for water, well, some would say that can be good for your engine. Some people put water down the throat of carbs at full throttle specifically for the purpose of removing carbon buildup. Not sure if I would be keen on trying this process myself, but it is a fairly well known practice around "old school mechanics"

There is no way 100 to 200 cc's of fluid is going to hurt your engine. Just makes your workspace uninhabitable for half an hour.

Foggin a bit might help with the mosquitos!!!

I hear they're big as cats down south!?

Carry small children away!?

Sure - I posted it here before, but since then the 250 FAQ has grown to
include a nice version I'll point there instead.

Remember they have a 2 carb setup, we have 4.
