Hi Guys,
OK my sons bike blew a piston and did a new top end. The compression post top end was 110. So we test drive it around the yard and seems to run fine for maybe 10 minutes then just completely falls flat with no power whatsoever. Ok so I tried to diagnose the problem but at my wits end and seriously could use some expertise.
Things I attempted to resolve problem after top end.
1. Cleaned Carb and jets, float and it gets plenty of Fuel
2. New Spark Plug and bike fires right up and can stay idling until runs out of gas.
3. Got new Reeds
4. Checked compression and it is at 110 WOT
5. Checked Rollers and were in good shape.
Bike runs great for like 10 minutes or until the engine gets warmed up. Once warmed up if my son puts any load on the quad (going up a small hill) the quad just cannot climb it as if just has no power and even on flat surfaces just runs slow. I have reached the end of my expertise on these bikes and am frustrated I cannot seem to solve this for my son. The bike is a kick start only so no battery.
I am at this point maybe guessing it is an electrical issue? Coil, Stator, CDI?
If anyone knows of a reliable shop in Southern California I would be willing to drop it off.
Thank you for taking the time to read my post.
