I was at the dentists getting my teeth cleaned and on my way out I stopped to get a fuel filter at the lawnmower shop. I noticed a 1970's era Sachs 50cc out front. I asked about it and bought it for $80.
It has some wierd problems...nothing that I've really ever heard mentioned here before. I'm at work now and I plan to work on it tonight and see if I can get it to run right.
Bike starts first kick.
Runs ok at first....25mph
Then it slows to a crawl...maybe 10mph after 2 minutes
But it still goes 30mph downhill.
It seems to run better when the choke is open
Anyone have a guess why the bike slows down after a minute or two?
I'm gonna check it out tonight and clean the airbox, exhaust and port, and carb. I'll also take a look at the rings to see if they look worn out or a if there is evidence of a seize.
