Bweston95 4 Posted May 10, 2022 Hey guys new to the page I’m trying to figure out why I don’t have spark I bought this bike a month or so ago it ran when I bought it brought it home and went to unload it out of the truck and it was just cranking and cranking wouldn’t start. Finally got it to fire rode it around the yard the next day parked it put new brakes on the back and now for some reason no spark Iv been over everything more than once still can’t find the issue, I just put a new cdi box, starter Solenoid, pulse generator and a new spark plug coil wire still nothing ( new plug as well ) When I bought it the guy did tell me that the starter button didn’t work had to jump it from the starter solenoid started fine at his house got it home different story. thanks in advance Share this post Link to post Share on other sites
Goober 1,547 Posted May 10, 2022 Did you contact seller? Maybe there’s a little bug he knows how to deal with. You’re going to need a Honda service manual —preferably printed or a good picture of the wiring diagram. did you put in all OEM parts? If were me I’d put all the OEM parts back in it and start over. 1 Share this post Link to post Share on other sites
Bweston95 4 Posted May 10, 2022 I did contact him and he seemed clueless on it like it never happened to him I’m gonna try to put a new key switch and kill switch and go from there Share this post Link to post Share on other sites
toodeep 1,712 Posted May 10, 2022 The regulator/rectifier is one of the most common things that will go bad and cause no fire on these machines. 2 Share this post Link to post Share on other sites
Bweston95 4 Posted May 10, 2022 I put a brand new one on still nothing Share this post Link to post Share on other sites
Goober 1,547 Posted May 10, 2022 (edited) New: you have the kill switch in run? The service manual has diagnostics for this switch Gotta use OEM parts, because aftermarket switches and modules can add to confusion. best move is to buy a printed service manual or get a good picture of the schematic. otherwise, buying a replacement OEM ignition switch not a terrible idea but probably not the issue. does it have a (recoil) pull starter?

Bweston95 4 Posted May 10, 2022 The guy broke the pull starter on it 1 Share this post Link to post Share on other sites

shadetree 5,429 Posted May 10, 2022 i'll ask this question again, was all these parts purchased from honda ?, or ebay or amazon ?. DO NOT BUY PARTS OFF EBAY OR AMAZON FOR THESE ATVS !. unless you are 100% sure they are indeed oem honda parts ?..why you ask ?, BECAUSE SELLERS ON THESE PLACES CLAIM THEY '' FIT '' ?, BUT ARE MADE IN CHINA !!!. 1 Share this post Link to post Share on other sites
Bweston95 4 Posted May 10, 2022 I got everything from Amazon everything fit perfect just still no spark the only 2 things I haven’t changed is they key switch and kill switch when I turn my key on non of the lights come on the dash but when I jump the Solenoid The neutral light and oil temp light comes on just no spark Share this post Link to post Share on other sites
Melatv 763 Posted May 10, 2022 Hi: When you say jump the solenoid are you jumping across the 2 large terminals? --- if so move the small red wire to the other large terminal post. Share this post Link to post Share on other sites
Bweston95 4 Posted May 10, 2022 Yes I take a screw driver and lay it across the negative and positive on the starter solenoid cranks the motor over the lights come on the dash but no spark 1 Share this post Link to post Share on other sites
toodeep 1,712 Posted May 11, 2022 Did the lights work the few times it was running? Share this post Link to post Share on other sites
Melatv 763 Posted May 11, 2022 Hi: Is the small red wire on the solenoid terminal post with the large wire going to the positive post of the battery? If not put the red wire on the solenoid terminal that is going to the positive of the battery. Share this post Link to post Share on other sites

Unlikely wires are improperly connected. Don’t be moving wires around unless you know exactly what you’re doing. i would put all the OEM stuff (presuming it was all OEM); let’s go back and start over. check your fuzes.

Fishfiles 17,025 Posted May 15, 2022 I would put all the O.E.M. parts back on in place of the after market junk and start over trouble shooting from that point. 2 Share this post Link to post Share on other sites
Bweston95 4 Posted May 16, 2022 That’s what I’m planning on doing tomorrow just confused as to why it has spark when it’s cold but after riding and getting heat in the motor I have no spark tell it cools off 1 Share this post Link to post Share on other sites
