Yamaha Enticer 300

Ok this thread will be for all my questions on getting my enticer 300 fixed up.

My first question is: Where should I start. The sleds sounds like she wants to start, but thats as far as I got today.

The plugs look new and the oil tank is full, and it has a half tank of gas or so.
I'm not sure how fresh the gas is, but I am asuming it was put in sometime this season.

I wil try and get some better picuters of it tommorow

You should try to siphon out the gas and replace it with fresh, this may help. Also a carb clean would help, and maybe shooting some premixed down the plug holes.

I'm going to check for spark tommorow, and I will pour a little gas down the cylinders and see what happpens.

I dont have the slightest idea on how to clean carbs, and I dont have anything to syphon the gas with

It has spark.

I dont have any gas though.

I am confident that it will run when i pour gas down the cylinders

There is info in the how to section, as well as on youtube. it is easy to do, and it provides cheap insurance. Any rubber hose will work, just got to get the gas to flow up the tube, and gravity will pull it down, and will continue to drain until, air gets sucked in.

It runs with gas poured down the cylinders.

So what should I do to get it running by itself?

It's a fuel problem so start by pulling the fuel line from the carb to see if the fuel pump is working. Put the fuel line into a clear container and pull the rope a few times. Does fuel come out? If not, it could be a bad hose inside the tank or a bad fuel pump. If you get fuel, you should clean the carb as was previously mentioned. If I remember, that has a butterfly carb on it, but the principle is the same. Count the number of turns in on all the adjusting screws and then remove the screws to spray cleaner in the passageways.

I think the line is frozen on.

I untightend the clamp and the line wouldn't come off.

lines are probably old and brittle and just stuck on. add that to your repair list. probably not enough flexibility left in them to cut them back and reinstall.

Right now I plan on cleaning the carbs and replacing the fuel line.

The carbs probly need cleaning anyway, and if it doesn't help then I will assume it is the fuel pump.

How should I get the line off then?

One more thing, The throttle seems hard to push maybe even little sticky?

Anything I can do about that?

use a utility razor knife and cut the old lines flush with the fittings. once the hose is out the way, slice the remaining hose stub off the fitting.

if i remember right the throttle cable wasnt a cable but a wire. could have some rust or corrosion in the housing, the pin at the flipper or the lever on the carbs could be sticky as well.

easy to figure out. simply unhook the cable at the carbs and troubleshoot from there. ist just one set screw at the carbs.

Do these sleds have thumb warmers? Because there is a couple thin white wires coming off the throttle area.

Do you know what size fuel line I would need? couldn't I just go to the local hardware store and get a fuel line that would work?


Sorry about all the questions, but this is really the first sled I have ever really worked on.

You should get OEM fuel line. Link: Yamaha Parts, Yamaha Snowmobile Parts, Yamaha ATV Parts, Yamaha Motorcycle Parts, Yamaha Accessories at wholesale prices

No if it had warmers, they're after market.

thumb warmer would not have been a factory item. could have been an add on or maybe its an added grip warmer. not the wires for the kill switch thats usually there is it?

fuel line is a metric inside diameter like 6mm, between 3/16 and 1/4. what happens is the 3/16 fuel line wont want to go on and the 1/4 is too big, depending on which fitting your installing on. you can adapt with some ingenuity and some gear style clamps. take the old line with you for comparison and note the size difference between the carb feed, the tank to pump, and the pulse line. you should see a different size.

The link isn't working for me. It just brings me to the site and I cant find fuel lines

The wires are probly for the kill switch(wich I got a kick out of because it spring loaded)

There s a little red switch on the left side inbetween the windsheild and handle bars what is that for?

I'm not sure of the year, but I am guessing '79 or '80

I got it now, and it shouldn't matter if it is '79 '80 or even '81? it should still fit?

if the switch is bar mounted, it should be the headlight dimmer. if its on the cowl it could either be a safety tether or heated grips.
