Dumping Gas in the Tri Z Cylinder/Carb Boot? Bad Idea?

[Darius1502]

My Z is tough to start when cold. Is it a bad idea to dissconnect the boost bottle hose and dump some gas in there.

I did it tonite and the Z fired right up every time.

The boost bottle connects to the boot between the cylinder and the carb. The gas would dump right there and I assume drip into the cylinder.

IT sure works good!

Will this damage anything??

You have that problem too? Takes me about 20 kicks if my Z sits for a while. The only problem I see would be a backfire through the carb, but I guess the reed valve is there so you dont get combustion through the carb, if you really wanna be sure though, dump the gas through the sparkplug hole, but it's kind hard to do that with the tri-z.

A couple questions for you guys.
1- Are your floats sticking? Is the carb bowl going empy while it sits?
2- Where is your idle mixture set at?
3- How old are your reeds?

These are the only things that ever caused my Z to start hard when cold. If the bowl is draining empty while it sits, then you have to kick the crap out of it to fill it back up.

If your idle mixture is too lean that will make it start hard when cold.

If your reeds are worn, it can make it hard to start.

Mine only does it if it's cold and has sat for two weeks or more, but I do try to run the gas out of the bike before I park it usually.

I have no idea how old my reeds are...I guess circa 1986!! ha ha!!

I have done the spark plug hole thing...but just taking that hose off the boost bottle is so damn easy. I put about 6 squirts of pre-mix and the trike runs long enough to prime the fuel pump.

I do think though that my float bowl does run dry when the trike sits. I have to kick the hell out of it and it just won't start. Once I put a couple squirts of gas in the spark plug hole or in the boost bottle line...she fires right up.

Hey, every two stroke I own needs to be primed if it has sat for a while. Can't figure out why. Air and liquid r's are not quite as bad as z's. But I don't even try to crank any of mine w/o putting a little gas in the plug hole.

That's odd. My R starts so easy it's almost funny. Even if it's been sitting a long time, usually two fake kicks and a couple jabs on the throttle will get it to fire on the first real kick nearly everytime. Even after the most recent rebuild when it had been sitting for 7 years it started on the second kick.

I use the boost bottle hose to do that when mine won't start. I don't care what anyone says all small engine do not like cold weather. My Z's start 1st or 2nd kick all year long as long as it is above 45 but any colder and no go. Snowblowers and such start easier in winter because they are set so rich when the choke is on. Try to start a street bike in the winter sometime. Brand new 1000 will hardly ever start if it is below 40.

The TriZ takes the first half dozen kicks to fill the carb float bowl by the fuel pump. It should only be a problem when it has sat long enough for the carb to dry up. There is an easier trick than kicking over the pump and dumping gas in it. The gas tank vent tube runs up to the front of the bike. All you have to do is blow in it to pressurize the tank, and put your finger over it, hold it about ten seconds, and it will force gas into the carb and you are primed to go.

Thanks Tim. As long as you don't see any harm in what I am doing...I guess I keep doing my method. I may even try yours...thanks!

Are you talking about the vent tube that goes to the back of the tank?

[twgranger]

mine starts hard too when it is cold out but when the engine is warmed up it starts the first kick.

Yes, runs from the gas tank all the way up to forks.

try starter fluid in the airbox after taking the filter off, or if you have a uni, u can spray right through it.
