Hello, I'm new here. I am a senior member on Pirate4x4, HAMB and a bunch of other boards. I have about 15 motorcycles and it's time to get the ones that are close, finished up. First on the list is a pretty nice 1976 Yamaha DT175. I picked this bike up and the previous owner sorted out the paper and a few easy things like tires and points. He tossed a china carb on there and gave up. I got the thing running kinda enough to know that the carb is junk. Here's the bike.


Soon after I bought this bike to rob the CDI off it but despite being beat to hell it rides and will do a wheelie with a 200+ pound guy on it so it get's put away for a rainy day build.


And here's a stupid video I made about the yellow bike. Never mind my not knowing anything about it. I'm very good with all other engines. I'm new with these 2 strokes

I'm going to get a VM26 carb for it and I'm down to two versions. I noticed these two carbs are set up very differently. My question is which one via the specs suits me more?
First one is this one. VM26-606. This one has the factory style choke pull lever. Here's the specs

Next is this one. VM26-8074. Very different specs.

Although I'm running premix, are these carbs both able to run the oil injection? Also since I have a tag for this bike which carb is more suited to street driving? Both of these carbs start off with a 190 main jet but then they are both very different. I'm assuming one is for a smaller engine with its 22.5 and 1.5 inch throttle valve. The other runs a 2.0 throttle valve and a 60 pilot jet. I'm not sure about the other specs such as needle, needle jet and air valve. School me please, thank you.

No matter what you put on you'll probably be changing jets and needle.
Just make sure it's made for 2 strokes, not 4 strokes because the needle jet is different.
