Ok so, My daughter's quad. This thing is such a pain in the aSpam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word . first off, we were having problems last summer turning it over, put a couple new battery's in it 4ah and 8ah and it always seems like it needs more juice to turn it over?
I use to be able to roll it back and forth and find the sweet spot in the stroke to get it to start. sense then Ive thrown a bunch of parts at it, now i cant even get a solenoid click when i push start button? Or headlight to turn on for that matter. parts i dropped in Starter,starter chain, starter chain tensioners/ guides,starter solenoid,coil,spark plug, cdi, voltage reg,stator, safety switch,carb air fillter,fuel filter.need help thanx

 

Update got it trying to turn over.will turn with side cover off

 

power problem still remains

 

How old is this thing? Hard start could be valves out of adjustment. As for the electrical issues i would go through the harness and look for any bad wires and clean and reattach all grounds especially the large ground from the batt

 

Update, got it turning over nice a few times. then it started sounding like the starter chain was hopping teeth now starter/motor feels stuck again.

 

No more problem wiring. i got the wiring taken care of. the quad is about 3 years old and in real good condition. could the clutch on one of theses things be the problem?
I read something that said this could be the problem, when i bought the quad it a clutch. my buddy worked on it so im not sure what it was. i believe he said something was installed backwards. But seens then it has been hard starting.

 

Tried to turn the motor with a wrench. it felt locked up, so i took out the spark plug and sprayed the piston. gave it a good turn and snap. removed the side cover and it was not the timing chain. so what did i break and whats the next step?

 

Got it, It was the roller bearings on the back of the pulley. One was missing looks like the other two were turning and binding. So the combination of the missing chain tensioner and the bearing. So with that being said, i now have a whole new set of problems that have me boggled. After firing the quad up i went to kill it flipped the switch and nothing. then i turned the key off nothing. pulled the tether nothing. had to turn the idle down on the carb tell it died. what in the world is going on?

 

pins popped out again

 

this time i tried to put a fat washer in, then i hit the bolt with an impact wrench. only ran it for a bout 5 mins but didn't pop out hopefully it will work.
