Nice. looks to be in good shape. Plastic parts are better than mine. I also like the idea of that rear spotlight. Does it have a dedicated switch or is it somehow hooked up to the reverse switch? As for the quad dying on you is there any particular reason you think it may be the fan control unit? There is also a fuel cutout relay. I'm a new member here and haven't poked around too much yet but there seems to be a number of threads on that issue. If you think it's fuel/carb related the first thing I would try is a good dose of Seafoam spray directly into the carb throat and also run a good strong mix in the tank as well. Could well save you a carb job.
Regarding the timing chain slapping I have the same issue and just started a thread on that in the repair section that you might want to check in on the odd time to see the responses I hopefully get. I'm really hoping it's just a tension issue and not a stretched chain.
Good luck with it all.
Thanks man I'll check that out and I saw a bunch of threads on here where people were having the exact same issue I was (dying while driving and then dying when put in gear) and they all said it's the fan control unit so I figured I'd try that before buying a CDI.
cam chain : D.I.D. all the way !. right side cover gasket is needed. while you have the side cover off, pull the pick up screen filter from the very bottom, why Honda made it so you have to ruin the gasket in order to pull the filter is beyond me ?!. dies when put in gear : your c.d.i. is bad !. shocks: forget it !..lol. no shocks mount up ( at least not oem bolt holes anyway ?..you must drill the new shock mounting bolts out in order to get new after market shocks to bolt up. lith battery: well..if it were me ? ( and its not ! ), just buy a battery from Honda, cost less, and subject to last just as long as any battery !...if ya keep it on a battery charger when not using it ??!!!.
Thanks for the info man you're pretty much the guru here! Is the cam chain job pretty hard? I've replaced one on an old 200x but not a 350. And I read the CDI could be the cause but if you see above I saw a lot of people saying it was for sure the fan control unit, since it was only $50 I went for that and will replace my CDI with an OEM one with the fan control unit doesn't fix it.
I'm also considering buying one of these cheap fuel pumps as a spare to keep in the quad, I ride in very remote areas far away from cell service and it's always in the back of my mind that my OEM pump could fail...If it failed I would use this to get home and replace with OEM I'd never ride for a long time with this but has anyone used one? https://www.amazon.com/Fourtrax-Repl...5C39K3JYYMQXZK
seeing how I've restored about 10 of the trx350's ( old school ), yeah..you could say I know a little about them !..lol. the cam chain is easy, what is hard ?, is having to remove all those parts just to replace it !..lol. the service manual will tell you their way ?, but honestly ?, i'd do it my way !..lol. remove the rocker box, remove the cam, you will need to rotate the cam from the left side on the crank 180 after you get one bolt out. 17mm deep socket, ratchet, easy. once the cam is out, remove the cam chain tensioner, right rear side of cylinder, drain oil, or, tilt atv on it's left side, so all the oil will be on the left side when you pull the right side cover. BE VERY CAREFUL WHEN PULLING THE COVER OFF !, YOU DO NOT WANT TO PULL THE KIC STARTER OUT !!. disconnect the reverse lever cable, remove the bolt out of the reverse lever, pry the lever off, when tapping the cover off, there is tabs around the cover, hit there with a mallet and piece of board. anything harder will break the tabs !. MAKE SURE ALL BOLTS ARE REMOVED BEFORE YOU GO HITTING THE COVER !!. while tapping the cover off, once after a few rounds, tap the kick starter back in, keeping it there, so it won't come out when you get the cover moving off. most have rust on the shaft ?, clean it with steel wool, fine sand paper, anything that won't mar the surface ?!, the reason your doing this : so you won't damage the oil seal !. after the cover is off, you will need a clutch puller tool to pop the centrifugal clutch, if I remember right ?, the threads for that are 22mmx1.5 rh . if in doubt ?, just look on ebay for the tool. I went to a place that sells bolts,washers, nuts, and bought a bolt long enough to reach in, and pop the clutch off. remove the oil splash guard , oil pump, DON'T LOOSE THE DOWEL PINS TO THE OIL PUMP !. and pay attention to the o-ring that goes on the oil pump dowel pin. I don't remember if the head has to come off or not in order to get the cam chain down from above ?, if not ?, drop the chain down from the top, have a piece of wire or string tied to it, so you can tie it off at the top some where. get the chain on the crank gear, put it all back together. check, double check, triple check your flywheel for the correct timing mark on top dead center on the compression stroke, if all is good ?, put it all together, set your valves, and fire her up. sounds easy huh ?..lol. you should have a service manual to guide you, I may have left out a few things ?!..lol.
