CR80 problems
I got my friends 1988 cr80 here, had no spark, i cleaned the sand out of the fly wheel/stator section. I dont know what the correct name for it is. And we got spark. Started it up and it ran for about a min, so i cleaned it again and same thing, i never took the fly wheel off though, it keeps doin the same thing. Is there a certain distance that that black box should be away from the wheel? Something i should do about timing? I dont know help please.

Following this thread.
Is this the first time this year the bike was started?
Is it spewing gas out the overflow ?
was the gas removed before it was put up for the winter ?
Sometimes if the gas sits in that carb for a couple months the gas goes bad and a small amount of gas goes bad quick.
On a bike that small even a small film can clog the small holes in the carb.
disasemble the carb and dip it ?????
yamaha makes a carb cleaner that you mix with gas and draw it up into the carb through the gas line. It works GREAT !!
Good luck !!

Re: CR80 problems
Well when you need a top end, you cant kick start it at all right? The kick starter wont move and the bike right? If that is so then i do not need a top end b/c i can start it sometimes but just for a second. Maybe piston rings? I dont know, thanks.
