Hello I'm new here. I'm working on a 73 yamaha dt100 lt2. So far I've gotten it running. Stripped it down had the frame blasted. Then paint the frame and all the parts and cleaning everything up. It's been some work to get the the point I'm at. I'm here hoping to find new people and maybe if I'm lucky some information on parts and stuff. Here's a few pictures of how the project is going. 

 from the UK.

If you haven't done so already, make sure that that paint on the frame doesn't interfere with the earthing points.

If you need a part, research exactly what it looks like before buying - lots of (innocently) mis-described parts out there.

CMSNL and Partzilla are good reference sources.

Welocme!  Nice work!

Technically what you have is an LT3.  Almost all the parts are the same as the LT2 but there are some differences like the air filter. 

Your LT3 is looking like it is on the road to recovery. I have a LT2 that is a future project. Main thing that I know of is the kick start shaft, end is broken off, but I will have time to search before I even start it. Again welcome to the best forum for 2-stroking nuts.

Supposedly it's an Lt2 paperwork and frame say lt2. Original owner I bought it from said it's an lt2. So idk.

Look up your frame/VIN number in the VIN tables in the Tech Library here (see top tool bar).

Yamaha is confusing with serial numbers...  LT2 and LT3 all have an LT2 prefix.  You have to look at the full serial number and compare it to the tables to know the model. 

LT3 will have a VIN number in the range of LT2-035101 to maybe LT2-080000 or so.

Worst is the 125's and 175's...  All have a VIN starting with AT1 (125) or CT1 (175) from the first models in 1969 through the AT3 and CT3 in 1973.  So four years of different models with VIN's that start out same as the 1969 model.  It's very confusing.

That makes sense. Considering this whole thing has been confusing lol. And looking like I'm going to have to do some custom work to even get it on the road. Headlight for one. Upper throttle cable for another. Nothing seems to cross over and not much available. I'm actually regretting even buying this bike, not to hurt anyone's feelings! That doesn't mean I'm giving up. Just wish I would have waited and found the bike I really wanted for the right price. But this came along and I thought ok. Here's a picture its current status as of today.

Nice work. look forward to seeing it all together.

 Great start.  Looking forward to seeing it when you’re finished. I love my little LT2.
