Default 2001 honda cr125 not starting leaking head gasket

     

hey guy i just bought this bike about a week ago i went out for a ride about an hour later it shut off just bogged out. I got new plug an cleaned out teh carb an airfilter i tried to kick start it wouldnt kick over so i rolled start it it started right up i let it idle for a bit then shut it off an it kicked over again let it idle for a couple mins i noticed a little white smoke so i shut it off let it cool down then i did a coolan change i drained out the old coolant which was to much in there an it was a nasty yellowish color so i changed the coolant did everything the way the service manual tells you to do it went to start it up as i was kicking it i felt a slight spray on my leg i looked down an i noticed that it was leaking out of the head gasket.. i looked through the service manual it says it could be a couple different things but it doent really go into detail. i was wondering what you guys thought any help/ advice/ things i should do would be awesome i just want to get this bike running right so i can get out an ride

thanks

drew

if i was you i would order a top end gasket kit, pull the cylinder head off, check for damage to both surfaces where the head gasket seals (on the barrel and head), if its ok, clean it up, replace head and base gaskets, then put it back together and see how it works.

Ok thanks makita. What's a good brand for gasket kits or should I just go OEM? I was looking on a couple sites an ready customer reviews an it was 50/50 some said they had to fabricate an some didn't come with all the pieces it was supposed to come with.. What's your take on gaskets?

If your going that far as to replace all the upper end gaskets you might as well put a top end in it considering you just bought it not knowing how much time is on it. Just my 0.02

Nope. seems like the top end metal gasket or the screws are loose on the cylinder. try to tighten up with 2 nuts an the same screw
