riverc 1,317 Posted January 26, 2020 Bike started right up,went riding was not sluggish ran fine.Stopped in the woods went to restart acted funny but started up.Rode about half mile stopped again went to restart and it would not start...What could be the problem it's under warranty.

toodeep 1,760 Posted January 26, 2020 On a lot of these newer ones just a touch of water in the fuel tank can cause instant issues and is more common than one would think. I would pull the tank cover off, remove the fuel line and use a hose to cycle some fuel into a clear container to check for water. 1 Share this post Link to post Share on other sites
riverc 1,317 Posted January 26, 2020 Thanks for reply,With being new don't think I am going to work on it.Going to take it to a dealer it's under warranty.Am just trying to get some feedback on possible causes. Share this post Link to post Share on other sites
Fishfiles 20,148 Posted January 26, 2020 Just thinking out loud , if you bring it in to the dealer and it is water in the fuel , they might not cover it under warranty ----- it might depend on the dealership ----- I know the new Bobcat Tier4 engines' fuel injection systems are very delicate when it comes to water in the fuel system , and know a few people now that have paid $5k and up , cause it wasn't warrantied , to find that out Share this post Link to post Share on other sites

Did not notice anything nothing caught my attention....It was running fine no signs of a problem till I stopped the first time was harder to start than it usually does.Second stop was a no go,did not start.

toodeep 1,760 Posted January 26, 2020 The fuel line is easy to remove from the pump. Pull the rubber keeper out of the way, push in on the line, squeeze the keeper lock together and pull it off. Should take a couple minutes to see if that's the issue. I've had some come in with less then 10 hours on them and all in had to do is cycle the water out of the system. The fuel pump is at the bottom of the tank where water collects. 2 Share this post Link to post Share on other sites
shadetree 6,036 Posted January 26, 2020 sounds like a bad fuel pump to me. a lot of the trx420's had problems with fuel pumps on them. Share this post Link to post Share on other sites
F250 guy 107 Posted January 26, 2020 (edited) If it was me I'd follow @shadetree, but I'd test the pressure first, if it's FI then if there isn't a port on the rail then unhook the main line and tee into it if you have the adapters and reconnect it, and check pressure. When HOT. I'm not sure if Honda uses a common rail or direct injection, cause a throttle body only flows air, so I may be wrong on what I told you, but the information is useful.

F250 guy 107 Posted January 26, 2020 (edited) @riverc, most of all if I were you I'd try to find a Sunoco station in your area that has the Optima Non Ethanol fuel, 92 octane. And treat it with 1oz per gallon of Seafoam. That'll cure your problem, also if you do go with my fuel fix, try to get at least 15 gallons or a girl caddy to store in, and keep the wheeler tank full at all times. https://www.sunoco.com/quality-fuels https://www.sunocoracefuels.com/fuel/optima Edited January 26, 2020 by F250 guy Share this post Link to post Share on other sites
riverc 1,317 Posted January 28, 2020 (edited) Went out this morning to see if bike would start.Pushed the starter button and it started,let it sit and idle till it warmed up turned it off for a few minutes,started right up hit the throttle sounds good also seems to idle good I don't know why it did that in the woods Saturday.

Melatv 797 Posted January 28, 2020 Hi: When you had trouble starting in the woods did you touch the throttle when starting the bike -- if so it will not let you start the bike for 15 seconds or more -- PCM looks at the throttle -- protecting the bike from taking off when you try to start it. 1 Share this post Link to post Share on other sites
riverc 1,317 Posted January 28, 2020 No,not that I remember,wife had to go over 2 miles to get truck and trailer.Took a while for her to get back.And it still would not start,it's been sitting on trailer since Saturday.Was getting ready to call dealer,thought I would see if it would start and it did...It's hot me puzzled why it did that.

retro 4,074 Posted January 28, 2020 I'd check/replace the spark plug before doing anything else. Maybe the porcelain is cracked, or the insulator cracked/shorted. 1 Share this post Link to post Share on other sites
Misterclean 420 Posted January 28, 2020 I would take it to the shop and get the incident reported on paper. 2 Share this post Link to post Share on other sites

Fishfiles 20,148 Posted January 29, 2020 You should have bought a 25 year old second hand , basket case 300 , that new stuff ain't what it is cracked up to be !!! --- LOL What about a vent on the fuel tank cap ?

Water on the other hand, just a spoon full, can cause instant issues. The ride home on the trailer might have mixed it up enough and the reason it started. 4 Share this post Link to post Share on other sites

It's never a problem, it's a project. I'm thinking of tearing my 93 down and redoing it, new plastics " probably green, and mud guards from a 96 maybe 96 a arms to get ground clearance if they didn't change the frame for 2x4 in 95 up". Might even powder coat it. Edited January 29, 2020 by F250 guy Share this post Link to post Share on other sites

Fishfiles 20,148 Posted January 29, 2020 TooDeep ain't lying about the water , it don't take much water --- Shade ain't lying about might be your fuel pump ----------- I seen the Can-Am crew here by the house , take on water in the fuel , pull the fuel pump out their tanks , suck the tank out and go get a new electric pump at the auto parts , I think it is a Mazda automotive pump that they use , wire it in and be running again in a hour --- warranty would be about two weeks for them to be told water isn't covered I know you live close to me , the dew and humidity has been really high , the tanks sweet inside if not kept full , and water gets into the tanks ----------- do you use non-ethanal and keep the tank full all the time , I have been told that water and ethanal fuel don't mix well 1 1 Share this post Link to post Share on other sites
