Sounds like you do need a CDI, and do NOT get a cheap China one as they are nothing but trouble.... 1 Share this post Link to post Share on other sites

Sounds like you do need a CDI, and do NOT get a cheap China one as they are nothing but trouble.... To go with what bcs said....those Chinese CDI boxes are wired wrong and just blow fuses. Powersportsnation might have a CDI for your bike that you could 'try'....but there's really no way to test them. Its super easy to post pics here...post up some pics and go introduce yourself in the New Member section when you get a chance. 1 Share this post Link to post Share on other sites
SlammedRanger 1,560 Posted October 8, 2020 Welcome to the forums. I moved your thread into the sport atv section. Follow the advice given above. The place to start is buying a cdi box. As from the sounds of it you dont have one at all now correct? Was the quad taken in for a no spark issue? Or the hole in the case? That part is alittle hard to understand. 1 Share this post Link to post Share on other sites
oh400ex 629 Posted October 8, 2020 Welcome! Great advice so far! Start with the service manual and definitely do not go anything but OEM for a CDI. If needed, you can get OEM used on eBay. They are reasonably priced and available. Did you get your old running motor? The service manual troubleshooting section. Start there! Good luck and let us know how it goes!

shadetree 6,036 Posted October 8, 2020 simple fix: fix the first motor, replace the '' stolen '' c.d.i. box with a new one from honda, problem solved. don't bother trying to get that shop to replace your c.d.i. , they will deny you all day long, last but not least, DON'T EVER GO BACK TO THIS SHOP !. 1 Share this post Link to post Share on other sites

Fishfiles 20,148 Posted October 8, 2020 Nothing too bad there , some JBWeld for the case and reshape the teeth of the sprocket with a grinder and Send It -LOL --- a classic running the chain loose scenerio Nothing wrong with Rick's CDIs as long as you buy it from Rick's directly , they don't sell on e-bay or amazon , I have so many Rick's I would have to count them , have never had any problems , 1/2 the price and depending on your year and model , there can be a performance increase from rev limiter delete and a timing curve Share this post Link to post Share on other sites
87Iroc 344 Posted October 8, 2020 You've had some great advice here. Looks like the chain took out that one at some point. CDI box is the 'brains' of the spark and the timing on Hondas. They are specific to the bike(the other guys may know what swaps to the 300ex, I don't)...but w/o that box you won't get spark. The one for my Foreman is 110 or so I think from Rocky Mountain ATV. Yours appears to be 116. Careful buying one off ebay as they may sell you one that is bad saying its good. Be careful. Looks like yours is semi-specific. Here is the honda p/n and what it was used on.(I guessed an 03...no idea what year yours is but looks like it may have been the same for many years) Quote This Honda 30410-HM3-003 MODULE, IGNITION CONTROL (CDI) fits the following models and components: Honda ATV 1999 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 1997 TRX300EX AN - FOURTRAX 300EX Wire Harness Honda ATV 1996 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 1997 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 1993 TRX300EX AN - FOURTRAX 300EX Wire Harness Honda ATV 1994 TRX300EX AN - FOURTRAX 300EX Wire Harness Honda ATV 1995 TRX300EX AN - FOURTRAX 300EX Wire Harness Honda ATV 1996 TRX300EX AN - FOURTRAX 300EX Wire Harness Honda ATV 1998 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 1998 TRX300EX AN - FOURTRAX 300EX Wire Harness Honda ATV 2000 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 1998 TRX300EX AC - FOURTRAX 300EX Wire Harness Honda ATV 1993 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 1994 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 1995 TRX300EX A - FOURTRAX 300EX Wire Harness Honda ATV 2002 TRX300EX A - SPORTRAX 300EX Wire Harness (TRX300EX'01-'06) Honda ATV 2003 TRX300EX A - SPORTRAX 300EX Wire Harness (TRX300EX'01-'06) Honda ATV 2001 TRX300EX A - SPORTRAX 300EX Wire Harness (TRX300EX'01-'06) Honda ATV 2004 TRX300EX A - SPORTRAX 300EX Wire Harness (TRX300EX'01-'06) Honda ATV 2006 TRX300EX A - SPORTRAX 300EX Wire Harness (TRX300EX'01-'06) Honda ATV 2005 TRX300EX A - SPORTRAX 300EX Wire Harness (TRX300EX'01-'06) Share this post Link to post Share on other sites

Even better if you have someone to TIG weld it for you. Will need some sort of brace for a hole that large if the pieces are missing. 26 minutes ago, Fishfiles said: Nothing wrong with Rick's CDIs as long as you buy it from Rick's directly , they don't sell on e-bay or amazon , I have so many Rick's I would have to count them , have never had any problems , 1/2 the price and depending on your year and model , there can be a performance increase from rev limiter delete and a timing curve IMO this is bad advice. Check my 450ER thread for a perfect example of a Rick's CDI in use... absolute junk. Maybe in utility machines they are different I don't have any experience there but aftermarket CDI is something I will never do. Since 300 fourtrax has same CDI as this bike Fish likely has actual product experience that I don't but just go OEM. You can probably use the one you already have... 22 minutes ago, shadetree said: change out the stator from the first motor, change out the flywheel from the first motor, install them in this motor, tighten that dang chain !. use the c.d.i. from the first motor, it should fire the spark plug. I don't see why this wouldn't work. Has your coil been tested though? Many different things cause no spark...

_Wilson_™ 6,603 Posted October 8, 2020 I'd just go with the oem cdi..... then if you wish to change, and take the chance ... at least you would have the spark issue nailed down 1st..... you might check with slammedranger .... he's the honda sport machine expert here.... i think he had issues with ricks to ?
