1974 Yamaha DT175
Reliable, fun, easy and cheap!
The rear drum brake was filling with water and mud in the trail.
Changed fork seals (one was leaking - they were original ones).
Changed sprocket and chain (they do eat these if you don't lube them correctly).
Still had the stock tire, and were a bit cracked, but OK.
The gas cable broke (mud entered it), had to fit one made with a bike brake cable.
The cable splitter going to the pump and carb was always full of mud. I then just removed the oil pump and run premix, with only one cable going from the throttle directly to the carburetor.
Changed the ignition points (prevention).
Seat cover was ripped off in the trails.
Very reliable bike.
The only thing that went wrong (and it went a couple of time) is the flywheel that got loose and broke the woodruff key. This would shift the ignition timing and the bike would not work properly after that. I had to pop the flywheel off, put a new woodruff key and tighten it all back together. THE thing is that it was my fault. Never tightened it enough. I found I had to tighten it a 40 foot pound. After I done it, had no more problem with it.
The only problem that was not because of me is that the rear brake was filling with water in mud when passing through ponds of water. Had to disassemble to clean it after each rough ride.
But overall, this bike was good. Very good.
Fast bike, great suspension (for small enduro)
5 speeds, 2 stroke.
Not that noisy. great handling.
Braking was OK.
The bike always started first kick even after a winter staying outside at -20 (Canada) with old gas. And yeah, it's easy kicking, you don't need strength.
The bike was never rebuilt to my knowledge, but was still going strong. Never tested compression.
Also, the bike had 2 hole for spark plugs: useful, when you're in the wood and one becomes wacky, just plug the other: take on sec! (the only bike I've seen with this feature)
This bike took a lot, and I mean A LOT of abuse and never said anything. Never let me down once (except for the flywheel thing, but again IT WAS MY FAULT!)
Reliable, fast enough to scare you, easy to work on, Dependable. Cheap. Can be street legal.
Just sold it (and already regret it). Now I have a 1985 CR250.
Would you buy another motorcycle from this manufacturer? Yes
