yz80 problem

[rastaman]

i got a 82 yz80(first year water cooled) just did the top end. but the bike wont start if kicked i gotta jump start it. the only time it would start when kicked is when the bike has been ridden for awhile and i turn it off n let it sit for like 30 seconds. i was thinking i need to rebuild the bottom end?

do you do regular maintence, like change the plug, airfilter, etc?

 

[rastaman]

well i jus got the bike. i havent changed the air filter but i dont think thats the problem and it has a new plug. im prolly just gonna rebuild the bottom end

Ahh, forget about the air filter, let's just rebuild the lower end. :yikes:

How could it be the bottom end?

Excuse my sarcasm, you are right. It is VERY unlikely that the bottom end will cause starting issues. I was bein a smart arse, the air filter is a GREAT place to start.

Excuse my sarcasm

that was funny...

Who measured the ring end gap and piston skirt clearance before assembly? I do remember 1 time, upon a now seemingly mistake I made, and just slapped a new top end in,,,, The ring was not seated properly, it was too tight, hard to start, and the rings failed prematurely. Not that the bottom end could be an issue, but?

ok thanks ill check that out but ill still rebuild the bottom end too bcus the guy who had the bike before rebuilt it but he didn't use the proper gasket and the also put the piston on back wards. good thing the bike was really cheap
