Honda cr125 86, engine kicks back

New cdi , on my first outing the bike ran well, all of a sudden it tried to stall then went into running backwards, then went into very rough running, on inspection the coil had heated up to a point that it melted. it has a good spark, now the engine has serious kick back through the kick starter ????????? any help would be welcome
cheers rob

    the piston being backwards wouldn't cause a kickback it would cause it to not hold oil pressure the way kick back is caused is through detonation which is a firing just before it's supposed to

Bike engine stopped

This problem may have many reason but you can try one of the solutions, when suddenly engine stops and kick rod is going smooth without resistance try push and start by directly in 2nd gear or 1st gear and after it starts keep the engine running by giving small revs for a min....

Hi , Sorry to hear this about your bike but follow these instruction . Firstly remove the spark plug . put your bike with the back wheel off the grown and in any gear try to turn the back wheel . due to no compression you should technically turn the rear wheel in gear . If this does not work and it will not kick start without the spark plug out and still remain seized i am afraid that you will need to look at getting a new top end rebuilt . Give it a try and let me know how you go .

My 1994 xr6004 has good compression and has had a new top end, it runs awesome and kicks over fairly easy when cold and runs/drives great, but as soon as it warms up and you shut it off or it stalls out,...

The fuel in the carburetor float chambers is boiling while it sits, and flooding the engine. If it has a fuel petcock turn that off, and let the bike stop through fuel starvation. Then there will be no fuel in there to boil.

i dont know what all you have tried so far, but check the fuel filter, usally in the tank above petcock. the compression seems fine as you had to bump start it in third gear. you can feel the compression of a bike when pushing it in gear, like a bike with bad compression you could push in first without wheel locking

No spark

I too have a 1087 Honda Shadow and after we rebuilt, cleaned and painted the bike, it would not spark.

Behind the battery, check the CDI box. Look inside and shake upside down, looking for the presence of water. Once we completley dried out the unit. The bike runs like a champ.

the other day I rode in the rain for 160 miles. Engine died. Went to the CDI, water was there. Dried it out and again the bike runs fine. I am going to seal my cdi unit now. and hopefully the problem will not come back.
