tri moto owners, i need your help!

**Mr.Jake** · 01-10-2008, 10:42 PM

the fitting is the crank breather, just put a hose on it and run it somewhere were it wont get clogged

**PureMetalKorey** · 01-10-2008, 10:44 PM

the pulser i was referring to, is the FUEL pump, sorry for the confusion guys.

if i were going to disconnect my oil injector how would i go about that, do i need to get into the engine and take stuff apart, or just disconnect the tubing and block the port into the carb?

**Mr.Jake** · 01-10-2008, 11:11 PM

disconect the tubing, leave about 2 inches of tubing off the carb and block it with a bolt or something. But make sure you block everywhere the oil injector was hooked up or the carb will suck air, and not run

**PureMetalKorey** · 01-11-2008, 12:41 PM

do you think the oil injector being hooked up and not working properly might have something to do with my three wheeler not running?

i already have pre-mixed gas in the tank by the way.

**Mr.Jake** · 01-11-2008, 05:03 PM

maybe, if its hocked up wrong it could be sucking in air, its better to remove it, believe me, then you'll not have to worry about blowing your engine

see, i'm confused, because i have a fitting coming out of the crankcase, but i've been told thats a vent hole, so maybe i should have the fuel pump hooked up to that, instead of the reed cage?

maybe i'll change out the fuel lines

The fitting on the top middle of the crankcase is the auto lube tube which connects to the carb.

**PureMetalKorey** · 01-11-2008, 10:24 PM

i'm getting like 10 different things about the fitting on the crankcase, i'm getting it's a vent, i'm getting that it connects to the fuel pump, and i'm getting it's connected to the carb. i don't know which it is.

if it DOES hook the carb, where does it connect because it's a 1/4 inch fitting, and there is only one 1/4 inch fitting on the carb and thats to the fuel input.

Frankly, I'm a little confused. You keep referring to a Pulser\Fuel Pump. I have a yt125 and it has no fuel pump. The fuel line from the petcock goes directly to the carb. So what you are referring to, I don't have a clue. And please, don't type such things as people are telling you 10 different things. If you don't explain well what is going on, it makes it hard to help you.
You say your fuel is premixed with your 2 stroke oil, fine, I'm not even concerned that you have a correct oil ratio mix. Just hook the fuel line directly to the carb. The fuel tank is ahead of and above the engine, meaning it should be gravity fed. Whatever the "Fuel Pump" is, bypass it for now. Make sure you have your fuel line going into the proper fitting. If you don't know which is the proper fuel line fitting, than you have big problems and maybe you should be looking some info up on the internet or buying yourself a shop manual for the yt175. Once the fuel line is hooked up to the proper fitting at the carb, turn the petcock to on and give it a pull and see what happens. Please let us know. Also make sure you have a fair amount of fuel in the tank, it doesn't have to be full. It would also help if you had a few clear pictures. I would really like to see what the Pulser\Fuel Pump is. My yt125 and shop manual are across town right now or I would post a couple of pictures. My oil injector is not hooked up and I premix my fuel also and my trike runs fine. But please have a little patience with the people who are trying to help you.

**Mr.Jake** · 01-12-2008, 12:36 AM

is this "fuel pump" on the right side of the engine (from behind the bike)? Inside a plastic casing? If thats what you are talking about its the oil injector pump. The 175 and 125 tri motos didnt have a fuel pump, they are gravity fed. where exactly is this fuel pump located?

**Mr.Jake** · 01-12-2008, 12:37 AM

and that 1/4 in. fitting is the crank breather, not a "auto lube?"

**PureMetalKorey** · 01-12-2008, 11:16 AM

it's just hard getting answers when 5 people are telling you 10 different things.

thanks jake, from what i've heard i think your right, everything i've read says it's a breather.

here is a picture i found on ebay of the fuel pump i altered it to try to explain where the connections go.

the connection coming out of the side of the pump which i named "pulser or return line" is the one i have hooked up the reed cage, i think that gives it it's vacuum.

i know there are some people on here that have no clue what they're talking about.
i've done all the basics, i wouldn't be on here posting if it was an obvious problem. so it's safe to say you can assume i have the gas on and the fuel line hooked up where it needs to be.

thanks for the help guys, i really do appreciate it, hope you all can help me get this thing running.

as of right now, i DO have the fuel pump bypassed. i also have my oil pump blocked off and i've got pre mixed in there, but the gas has been in there for a long time i think i might drain it and run new gas, what ratio do you guys mix?

**Vealmonkey** · 01-12-2008, 01:46 PM

The mix ratio depends on whose 2 stroke oil you are using. Usually somewhere on the bottle it gives the recommended ratio. I don't think you mentioned it, but are you using the correct spartk plug? Is the spark plug clean and properly gapped? I don't know who put a fuel pump on the trike but it doesn't belong on there so there might be other wrong things with the trike. Where do you have the idle screw and air fuel mixture screw set at to start. I would say around 2 turns out from seated would be a good place to start. Please get pics of how the fuel line is hooked up and some of these other parts you are talking about.

**Mr.Jake** · 01-12-2008, 02:12 PM

the ratio reccomended for tri motos is 32:1, but alot of people run 40:1. the spark plug i believe is a NGK BR7es. And if you bypassed the fuel pump, that fitting going to the reed cage needs to be plugged, my mistake was putting a gas line directly to it and it poured fuel out the exhaust! (Dont do that) So plug that aswell.

I checked mine and it does have a place to bolt the fuel pump (is it on the left side of the frame, closer to the front?) But i never used one, i think they must have been used only of you have the oil injector hooked up so that it wouldn't try to suck more oil than gas, but this is just my theory.

Mine runs great without the fuel pump, so i'd just take it off if i were you, less things to worry about!

**Mr.Jake** · 01-12-2008, 02:16 PM

Vealmonkey, i remember looking at a diagram of the tri moto, and it did have a fuel pump, but as i said, i think it had something to do with helping the gas:oil injection ratio. That or it was used on a different year

**PureMetalKorey** · 01-12-2008, 05:46 PM

i have the right plug in there, but i was thinking about it yesterday and that fuel has been sitting in there a little over a year, i think i'll probably end up replacing the fuel, and replacing the spark plug as well. i have my air mixture screw set to 2 1/4 out.

i'll also, completely plug off the oil pump and block off the fitting on the reed cage also. tomorrow i'm going to work on it with a buddy, who has alot of experience. maybe with those changes it'll fix the problem.

if you guys think of anything else please let me know, i'll let you guys know how it goes!

thanks for the help guy's it's really appreciated, wish me luck
