Oh yeah there’s plenty of white smoke. I also recently did a leak down test and vacuum test. I adjusted the fuel mixture yesterday and it got a little better. Still dying unless I feather the throttle though. 

Happy to be corrected but sounds like you might have popped the wet side crank seal. Order the Clutch cover gasket and seal ahead of time if you decide to investigate it. Might consider replacing the clutch disks while you’re in there or just oil the new cover gasket before installation. Then cook that exhaust Pipe to burn out the oil. 

DT3 was still running through spark plugs when I last rode in the fall. I think that when I installed the new throttle cable I made it too rich in the oil pump. I still don't think there's a crank seal leak because I did the vacuum and air leak test in the fall. I am scared to turn down the oil pump due to leaning out is obviously bad so I am going to test premix and see if that still fouls plugs when it warms up. I also really need to cook my exhaust and I have gotten scammed on my exhaust gaskets twice now... anyway I'm just happy it starts in two kicks with a fresh spark plug now. putting a fender on soon as well.

Might just need a pipe burn out then a Damn good Thrashing.

Thats great to hear and I hope thats all it is. Ill try to throw it in the burn pile this weekend

After reading through this I would be replacing the wet side seal. It's not that much work and eliminates a common problem on these old bikes.

That sounds like a good idea, I'll get searching for crank seals.

It's springtime in SD now so I got the DT out of the shed. I am still waiting on a crank seal but I decided I would pre-mix to see if my pump was over-injecting. It started the first kick and ran pretty well all day which was nice. I am going to cook the exhaust and replace wetside crank seal I just got in new tires and it should be good to go. The biggest problem is that I got beat in a race by my friends Honda 125.. So I need to find some speed bc I wont stand to lose. Hope this video works... 

I hope I can laugh about the race..
   Its spring up here by Lake Superior in MN... I pulled the old grey mule(RT2) out of the shed.. Having winter boots on.. I didn't dare give it a kick.. Down the hill, I'll be the rear wheel spun half a turn and it came to life! Well, heres to a new season!

Haha, I am also a northern Minnesotan but am currently relocated. I'll be laughing about the race when I'm blowing smoke in the other guy's face haha hopefully my new crank seal solves it!
