I did some Googling and come across your posts on DT50 compression Mark. My service manual does not list a number. With a mighty 5:1 compression ratio, I can see you’d get low readings.

I did get a new 12T front sprocket so I can switch over. That’s what it had before. With the 13T it seems to have the same top speed at 45mph.

I’ll probably just keep running it until I lose power, or it gets hard to start. That’s usually an indicator of low compression.

What I really need to do is get a little bigger enduro for those trips out of the neighborhood.

Does anyone with a DT 50 have the oil dipstick? I don’t have it in my tool kit. I’m pretty sure my gear oil is overfilled as it is to the bottom of the Threads. I’m pretty sure it should be lower than that but I’m not sure how much. Anyone has this and can give me a length measurement of the dipstick I would really appreciate it. I do need to change my gear oil, it does not look very good.

Many times over the years i've seen underpowered smaller twostrokes caused by transmission filled to the top. People see a hole & fill it up, then the drag slows it down. Drain fully & fill with correct amount, which will be way down near the bottom of the clutch so its not paddling through it.

I have one, the question is where?  I looked around and haven't found it.

Draining and refilling with correct amount is the best way to do it. 

P.S.  For some reason the dipstick came with the owners manual, not in the tool kit.  That how I got mine.  Bought a NOS owners manual and it was in the sealed bag.

Yeah, it needs to be changed anyway. I’ll just do that. I’m sure the capacity is in my service manual.

It does seem to have a slight leak after riding but I haven’t been able to pinpoint it yet. Could be the shifter or countershaft seal. The oil tank lid doesn’t seal 100% and some splashes out when riding. Hoping if I get the right amount in the leak will stop... a guy can dream.
