After 50 years at this motorcycle thing and something like 33 bikes I finally have my first Yamaha Enduro; a 1975 DT400. In fact my only other Yamaha was an SRX600 which I bought as my first set of wheels after graduating from college.
Ive spent a few days catching up here, downloading manuals and talking to Dave about the pipe and Rich about the engine ..... and the beast is now in many parts about to be upgraded !

Hey everybody, My name is Joe and I am extremely new to the dirt world. I am actually on here because I got my son an old '79 YZ125. He fell in love with dirt biking instantly and we'll probably be upgrading to something newer very soon. In the meantime we're working on getting this one running again.
I don't currently ride but I would love to be out there with him. Maybe I'll find something that suits me just right and be able to get some more bonding time with him.
Not a mechanic per se but have always figured out how to work on my bike. To me it's part of being a motorcyclist. Sold my 1975 R90 BMW awhile back and found I miss tinkering. My Honda NC700Xdct doesn't require a whole lot of attention. Pretty sure that won't be a problem for awhile. Picked these up two weeks ago. How's that line go? "they were running when I parked them" I know the guy I bought them from and he bought them new.

Hi guys, I recently became the proud new owner of a '72 DT2. I learned how to ride on various 60s and 70s Honda 110s which were always hilarious to ride. They're more of a scooter than a trail bike. I eventually got into newer 4 strokers, but at some point I just caught the bug. I saw a grot-black Yamaha 2 stroke on Craigslist that "used to run just fine" and pretty much bought it sight unseen. When I got it I didn't really know what year it was or even what model it was, but the VINs matched and that was good enough for me. I was able to figure out it was a '72 DT2, that at one point was probably even Pearl Yellow. So I got all new seals from Yamaha Parts and brought it to a friend of mine who helped me get it up and running! Once I knew it ran, I did the only logical thing you can do. I took it apart.
Tidy up the frame and remove some of the unnecessary brackets.
Repaint the frame.
Replace the mishmash of bits that came with the bike with actual motorcycle bits.
The only problem I'm having is I can't get the rear swing arm bolt out. The grease zerk had broken off and I'd like to remove the bolt to service the fittings. It spins when I have a wrench on it, but not very well. I've tried penetrating sprays and some hammering with no luck. I didn't want to do anything too wild for fear of damaging the frame. I've looked at the diagrams but I can't see anything that would prevent it from coming out. Am I missing something? Any tips I should try for getting this thing out? Any help is much appreciated!
Edit: It's definitely a DT2

Just to make sure you get the right parts for your bike, if it s a '72 250, then it will be a DT2. The DT250 didn't come in until '74 and was, by and large, a completely different bike. I'm not trying to be a "rivet counter", but I'd hate for you to waste money on the wrong parts!
Your bike will share many parts with the RT2, DT3 and RT3. Check out the manuals in the Tech Library here and also sites such as Partzilla - if you click on an item on their site it will show which other models used it.
DEET on the site here is good for new wiring, wire sleeving, parts refurbs and hard to get parts.
If you intend using the lights, then probably best to fit a voltage regulator - see link at the end of this post.
What's stopping you removing your swing arm bolt is probably that it is rusted to the collars that sit inside the swing arm and which the bolt goes through. Use the search facility in the menu bar towards the top of the page to see what others have done - the members here really can be inventive at times!
Good luck and don't forget to keep us updated with photos!
Howdy all, I figured its about time I introduce myself. I've grown up on motorcycles (especially vintage BMWs like my daily rider) and a few years back I picked up a 1976 DT250 for $100 and I've been hooked on these old enduros since. The 250 has mostly been used as a farm bike and for some trail riding in northern Minnesota, and it received its Vermont registration this year so it may become road worth soon as well. More recently I've picked up a couple 1978 DT175s and a 1979 IT175 as project bikes. My main goal is to get everything running smooth to get some buddies on the trails with me, then maybe start on some slow restorations as time/money allow. I really appreciate this site for the resources and everyone's experiences. More often than not, I find myself logging on just to see what everyone else is up to. I look forward to sharing more with you all in the future as I start working on some projects!

Welcome from NZ. I had an IT175 exactly like that about 30 years ago."78 or "79, steel swing/arm. Actually was a lot of fun to ride but the funny story was, i bought it burnt out off the insurance company for wrecking value as no-one tendered for it. Had no 4th gear so i found out when i got it running. Wondered if it was burnt on purpose to claim insurance. Having an aversion to spending money--i remove the broken gear & raced it like it was for a while just going 1-2-3-5-6. Stupid yeah, but i do stupid well lol. Wish i took some pics from those days.--before digital cameras though.
