DeTaylor 48 Posted June 2, 2022 Hey guys, been a while since I posted on here. Was riding my 450ES the other day and it started breaking up. Parked it in the driveway where it died and wouldn’t restart. Checked and it isn’t getting spark. Replaced the spark plug and no luck. What would your recommendation be to check next? Stator? Coil? Hoping it isn’t a stator as they are over $250. Thanks as always! Share this post Link to post Share on other sites
Fishfiles 17,031 Posted June 2, 2022 DeTalyor , I would say the most common no spark culprit next to the spark plug would be the CDI , and as far as I know there is no way to test it other than relace it with a known good cdi : You could try this , take the CDI off , preheat the oven to 450 degrees ( when the wife is not home , if she is picky ) and stick the CDI in for 8 minutes , remove ( without burning yourself ) let cool and try it , won't cost nothing , it will resolder the connections and remove any moisture This is Partzilla below , they are a little higher priced than say Rocky Mountain ATV ---as far as I know Rick's Motorsports doesn't do a TRX450 CDI , but it might be worth a call to them , as they are the only aftermarket CDI supplier worth buying = Rick's Toll Free: 1-800-521-0277 or +1-603-329-9901 IGNITION CONTROL MODULE 30410-HN0-A01 by Honda $124.93 2% OFF $121.99 Share this post Link to post Share on other sites

I found a cheap version on Amazon with free returns for $60. Think I’ll give this a shot to test with and see if that’s the issue. If it is, I’ll go ahead and order from partzilla.

Amazon/Ebay electrical parts are very hit and miss and short lived , I would " strongly " suggest to bite the bullet and buy OEM < or I would feel better buying a used OEM , there is a place called Power Sports Nation , they are a dismantler , they will give you 30 day warranty and a good price , if , they have one in stock 2 Share this post Link to post Share on other sites
Fishfiles 17,031 Posted June 2, 2022 PSN has 5 choices for a 450 CDI at the moment, they are going for $38.00 each , they will give you a 30 day warranty , here is a link https://www.powersportsnation.com/saas/pliable/searchresult/?search=450 cdi&make=Honda&year=2004&model=Foreman 450 Share this post Link to post Share on other sites

I fully plan to go oem. This is strictly to test with. Will return once I confirm if it’s the issue or not. Share this post Link to post Share on other sites
Fishfiles 17,031 Posted June 2, 2022 Good luck with that , if that new aftermarket cdi doesn't spark , what have you really proved !!! It could still be the CDI cause aftermarket parts have been known to not work from the get go , that's what we are trying to tell you 1 Share this post Link to post Share on other sites

toodeep 1,712 Posted June 3, 2022 Since it was just parked make sure the left handlebar kill switch didn't get bumped. The most common thing on the 450 for no spark has been the regulator for me. It could be as simple as a blown fuse as well. Share this post Link to post Share on other sites

Kill switch was the first thing I checked since I had done that to myself in the past. Checked fuses yesterday and they all looked good. If the CDI doesn’t solve the issue, I’ll look into the regulator. thanks!! Share this post Link to post Share on other sites

If it doesn't work they will send you a replacement or refund your money. They aren't as cheap as they used to be but they do stand behind what they sell.
