My nq50 was running really slow, so I kinda retired it. I noticed that there was a lot of lash in the throttle, so I thought I'd see if thats why it had gotton so slow.
But, depsite having been a runner when I parked it up (about 2-3 months go, but it's been in the shed, and it's summer here) she wont go.
Then I noticed that there was oil dripping out the side cover. So I plucked it off and found that it was leaking at the cank seal. Are these just a plain jane old seal? Maybe thats why she had lost some speed?

Sealiness
Greetings:
CGJ's right. Don't just replace the seal. Check things.
In Theory, seals can just wear out because they're old, dry-rotted, ozone- and/or solvent exposed, etc. In Practice, in my experience a seal failure has always been secondary to a wobbly shaft. Crank bearings at a minimum. Hope I'm wrong this time. Good luck!

I wouldn't mind betting the crank is a little bent. I noticed a little bit of runout aaaaages ago when I swapped the belt for a used but less worn one.
The bore has a decent amount of wear, so it isn't worth getting too carried away with the repairs. I was planning to give it to my brother in law. he wants a scooter to go collect his mail, and turn on the irrigation on his block of land.
