Why wont my 89 polaris indy get spark? i was told it was the cdi or the coil so i put new ones in and still have no spark, but the head light lights up when i pull the pull cord. what else would cause it to have no spark?

check conections on new parts just had that deal new cdi had one wire that pushed out just enough to lose contact. sounds strange but it happens.

Check the unit for spark, I use a new spark plug and just disconnect the plug wire from the one installed and ground the new one to the head or block and then crank it over to see if it has blue/white spark at the plug electrode. If not make sure the kill switch/circuit is functioning properly. Check the spark coil leads to make sure the wires are intact. I would also check to make sure voltage is present to the cdi pack and that the wires are secure.

fyi, something to watch out for on those is bad crank seals. will allow a lot of air in and cause the engine self destruct. before the cdi try simpler things like coil and making sure all the wiring is right. good pickup coil.

Did you get any good advice i have the same problem on my 1996 indy 500 efi. LET ME KNOW [email protected]

I had a simular problem with my 99 sportsman 500 and it turned out to be my pulse coil somehow became out of alinement. The pulse coil air gap should be between0.016 to 0.040 inch, But I would start by checking the coil it should read 0.3 to 0.5 ohms. Good luck and hope this helps

cdi box on top of air cleaner not making proper contact keep wiring clips tight with zip ties

cdi box on top of air cleaner not making proper contact to check keep wiring clips tight with zip ties should work for quite a while cdi box cost $300+

try checjing your coils thats could be why u dount have spark

Sounds like you need new wires.....but the cdi box could be working only on one cyl. also........I would try new wires first.....

i have trouble starting a polaris indy 500 1990 new gasgets, pistons rings all i does is back fire through the two carbs
