Gpz500 wont start

[@abelfitiu2737]

Hi, I know it's 7 years later since you posted, but i kinda have the same problem. It starts just fine a few times, and then, outta nowhere it keeps on cranking but doesn't start, like it doesn't have what to ignite, but the spark plugs are new, battery is good , carbs are cleaned and sync, floating level is good , fuel petcock has been repaired using a repair kit. It just drives me crazy , i tried everything and still no hope :/ . Did you solve it? Thanks.

i have the same problem, check if you have normal sparks on the spark plugs, [ you must to pull them out both,if not is the CDI unit

@@nikostaxas1275 Thanks for your reply, everything (including the spark plugs) is either new/changed or within specs. I kept on reading on forums that it might be the starter clutch , i opened the stator case today, but everything seems to be ok, and i can't take off the flywheel :)) it's stuck, even the thread on the puller was damaged but the flywheel didn't even move. Even so, everything in there seems to be ok, i start thinking that the CDI may be the sucker...

if your engine doesnot turn with a good battery you must check the cables on the starter.if the engine turns but not fire check the spark if it comes on the spark plugs.tell me if you have spark.
