    I bought one of these Tri Moto 175's new in the early 80's. Blew a piston riding through wet snow and slush across a lake. Warranty covered the repair:). My first new 3 wheeler was the Tri Moto 125. Good times!

      but nowdays they are still dangerous but less cause you make the rear WIDE AF and its already better. love how the cboys broke that engines multiple times cause the air filter is a cone filter near the rear and they went full send tru water, and that is why you want and need a air box...

    Nope not the original tires my man. The rears were matching with your front tire, a dimpled knobby tread was OEM. Own 2 of these things and was around when they were brand new have one as a kid. The one I'm building right now is a Franken Trike for better handling and more comfort. The neck was removed and raked to 24 degrees which matches the Honda 250r frame layout and using triple trees and the entire front end off a trashed Honda 250r. Engine has been fully modified and built for performance. Custom crank, welded cylinder deck and installation of a Yam DT-175 jug with the best of the cylinder heads from 85 with the center located spark plug and shaved for higher compression as we as ported mildly. Using the larger reed cage of the DT and a custom intake and boot running a 28mm Mikuni round slide. Clutch was modified for a higher stall speed engagement as well as the DT cylinder was modified, they had great transfer ports but a poor exhaust port design. Welding up the top of the exhaust port on the outside and the removal of the restrictive blockage of the original casting was removed for a free flowing downstream system. They run pretty well though even in stock trim when they aren't beaten into the ground and left for dead! Lol.

    I have had good luck with a few ounces of ATF in the old tires or good old fix-a-flat to slow/stop leaks and get more life from those old low-pressure tires.
    Especially since it's so important for the tire OD size (pressure) to match for the back on a live axle rig.

    Safe to say that carb is definitely going in the carb dip for awhile! That was some nasty crap in there. The oil in the carb likely leaked past the pump and check valve if it sat for a long time. My H2 Kaw triple used to do that if it sat for awhile.

    Those metal stick valve stem bar tools come in handy for replacing them with to. They pivot to pry down to pop them through the rims very easy to with. A little bit of soap they will pop through until it seats into place when the stem is to the putter rim edge. Just make sure that area is cleaned up good first. Before reinstalling A new replacement vavle stem in it's place. Yes those tires needed replaced A very long time ago. A 1/4 cup of kerosene to presoak into that muffler.& then burn it out good. After the exhaust has been removed from the engine will bring up the tourche.& horsepower to. I remember that three wheeler growing up years ago.

    As others have said Yam Dt175 motors almost bulletproof and will shrug off plenty of abuse. In '78 they revised the model with a monoshock rear, cdi ign, lighter plastic components and a six speed transmission to make a very popular and successful trail bike, more nimble and responsive than the rather heavier and slower revving 250. Wondering if your trike has a 5 speed, as it probably weighs more?

    LETS GOOO im a big fan off the yt125 and 175 by the way the number one problem with these things are the crank seals it can cause higher compression feel and probably wont run btw haven’t watched the video yet haha

    Seen a few 200s and 225s for sale cheap in Michigan lately. The 175s are pretty rare anymore.

      Yeah I see the 200s and 225s up more than the 175s.

    The original oem tires were the Dunlop knobbies that would have matched the front tire on it.

    One thing I found in life if I ever came across any oil injected machines I would remove the oil injection and mix the gas myself ! After blowing 3-4 engines mostly Yamaha after rebuilding remove the oil injection and the motors would last for years ! It seems most oil injection systems could not keep up at high rpm !

      aways premix and block off oil ports so dont have a air lean mixture my first 175 had a broken oil injection line

    Just got a 08crf250r. Gas has been in it since last fall. Starts fine, idles fine and no bog. Once you get into the mid rpm’s the bike spitters and looses power and gains the power then looses it again. In the high rpm’s it’s fine. Anyone know what’s going on here??
