    Bike will not start

    I understand but my logic was that the chip would not prevent it from starting it. I didnt want to put a new top end on it and have it still not run for a different reason. Also I could not find the top end kit that the past owner said they used. She said it was over bored to around a 90, so I looked around for one like that because I couldnt read the number in the piston. I cleaned the carbon off and it turned out to be stock size. Im going to order a new top end soon along with a clutch side crank seal. Thank you for the response.

    Update, it starts but you have to be in the throttle to keep it going but runs like crap

    Bike will not start

    Every time I take the carb apart there’s gas in the bowl and I tip it and it pees out of the over flow. I was only hit power band twice in 2nd and 3rd down the street then slowed it down and pulled in the clutch, very easy on this motor. I took the reeds out to inspect them and checked the piston along with looking down the spark plug hole. I found a small kind of chip along the edge of the piston but didn’t hear anything that sounded like it took a chip out of it. No Metallica in the oil also. I think it may be a leak on the reed gasket but I don’t know.

    My cr80 was running just fine, started first kick everytime then I was riding it down the road and pulled in the clutch to start slowing down and it died. It will not start. I have cleaned the carb twice and checked the reeds, swapped the spark plug and checked the stator, coil etc. the only time it starts is when I put fuel down the carb but only runs for a few seconds. Fuel is getting to the carb. Any help? I’ve been trying to start it for like 4 hours

    Cr80 kickstand

    I’ve got a 1989 cr89 and am using it for trails and whatnot and need to install a kickstand. There seems to be a mount behind the left foot peg for a kickstand but the only mounts I can find are in Australia. Does anyone know where to get one of these mounts and the kickstand with bolt and spring? Or any better ideas? Thanks

    Cr80 exhaust leak

    Sbest thank you for the information, I checked my jetting and the pilot was a 42 when the service manual says 52. I have no idea why the past owner thought that was ok but whatever I am getting a jet kit tomorrow and will see. Also there is a new o ring on there but the expansion chamber just doesn’t line up, it is not leaking too bad so I will try the jetting and see if I gain back the power. The mix screw is all the way in and it still runs like crap.

    Cr80 exhaust leak

    The leak I am talking about is because the expansion chamber is kinked sideways and allowing oil to come out of the right side of it. I’m using all the stock mounts for the expansion chamber but I just doesn’t want to line up and seal. And is it really normal to have so much trouble getting it going in 1st? I most of the time have to roll it then hop on and go.

    Cr80 exhaust leak

    I have a 1989 cr80 with a 2004 cr85 engine in it bored to 90 ish and it seems to run fine when it’s in the power band but in the low end it has no power and idles for about 20 seconds or when you open the choke it loses the pop in the idle and just sounds boggy. You have to get it into power and and feather the clutch to get it moving without a stall. I’m thinking it has something to do with the exhaust leaking at the flange off of the cylinder and the expansion chamber. I got a new metal gasket ring thing and the spring and put the orange high temp gasket maker on it and it still leaks. Anyone have any advise on sealing it?
