So went to start the 450i today. Dead battery. We charged it enough to start it. Now every time I touch the gas just a little, it dies as soon as you let off. Checked the spark plug. It was a little dirty, so we cleaned it up and checked the gap. Made no change. In order to start it you had to give it throttle. The. As soon as you let off it dies again. So we thought it had bad fuel. Put some stabilizer in it, then took for a ride down the road to mix it up. It started skipping at 20 mph and cutting out. After that it died and wouldn't start. So we used and come a long and loaded it on the trailer to bring it home. Once I got there I started it for sh**s and giggles. Damn thing runs like a champ now. Drive it for 15 minutes and it stalled 2 times. Not perfect obviously but considerably better.
So I am geussing it is bad gas, tomorrow I will siphon it all out and replace with fresh super and stabilizer. Unless anyone has any better ideas
Thanks

sounds like a charging system issue, not enuf power to operate the fuel pump properly
-
Maybe because the battery wasnt charged enough?
-
why was your battery dead to begin with ?
even with a dead/low battery, the charging system should put out enuf power
the reason I suggested failing charging system is that is exactly how my V-Strom acted when the charging system failed
-
It only has 138 miles on it I should hope the charging system isn't failing. It did sit for about a month and a half with no use and maybe my winch caused a drain somehow
-
have you been using the winch without the engine running or other accessories ?
had mine just a year now, just over 800 miles, no issues at all except 2 nearly bald rear and front tires @ 50% or less (95% street use) and had to replace my rear brake rotor cause it got dinged when I loaned it to one of my employees to take to Jericho and the read skid pan got ripped off
-
Well it does sound like it might be an electrical issue. If you can get it started put a voltmeter across the battery terminals and see what voltage your getting. If low that might be your issue.. is your battery capable of holding a charge? I have seen batteries with a shorted cell cause electrical problems in vehicles many times. This sucks on a new machine but hopefully it will turnout to be something simple. I would test your battery first as these machines are now all electrical gizmos and any change in electrical current can cause things to go whacky. If your still under warranty you might consider returning it to your dealer, however you will still need to check the battery first as these are probably not covered under warranty.

No I disconnected the positive in the winch because it was malfunctioning. It may have drained it enough before I parked it I guess. But now that the battery has a full charge it is running better. I talked with my cousin who is a marine mechanic, and he said it is most definitely bad gas as I thought. And that the battery being dead was just a coincidence. Although being dead and just boosted may have not allowed enough power for the fuel pump to work correctly
-
I have had it on my trickle charger since last night, it's saying it is a full charge and that the battery is good. Didn't get home until 8 tonight from work. So it will have to wait until tomorrow to work on it more.
I hope I don't have to bring it to the dealer. The one 10 minutes from me dropped kymco and the next closest is 2 hours away
-
UPDATE. Evacuated all the old fuel out of the 450i. Replaced it with new SUPER with stabilizer. Runs like a champ. No problems. Ran steady for about 45 minutes tonight. Hopefully that is the end of the issue
-
Glad to hear you have is fixed!! The factory does say it can run on regular fuel 87 octane, but I use the midgrade (89) in all my toys just to be safe. today you can get bad gas or water in the gas just about anywhere, no safe places anymore. I do throw some fuel stabilizer in the tank every once in a while in all my toys just to be safe. I would keep an eye on your battery as these small batteries can go to hell real quick when drawn down to low as they are not made for that. If it is not a deep cycle battery and these are not, the mfg recommends not dropping below 60% charge or internal damage can occur just like a standard automotive battery.

I a set up a quick disconnect for my battery maintainer so whenever the 450i is in the garage it will be plugged in

I have only used non-ethanol rec 90 in mine since new. Never had a problem. Ethanol will eventually cause a problem in any small engine. Love my 450i. 👍🏻😃

no, lack of use is what causes the problem, I have been using e-10 for years, even using stabilizer does not prevent gasoline, e10 or e15 from gunking up fuel tanks and lines that are not used for a period of time, the ethanol (or any other solvent for that matter) loosens the gunk that is build up and moves it to the carb or fuel injectors that have fine passages and plugs them up
if you use your small engines regularly and never let fuel sit in the tank for more than a month you will never have a problem

With a new machine there should not be any gunk inside just yet, however I do agree with sitting for a long time. Whether gas is treated or not any long term sitting will cause fuel problems. I make sure that doesn't happen so I use that as an excuse to ride mine almost every day even for a short ride. I also keep the fuel tank low until I know I am going for a really long ride so that I keep adding small amounts of fresh fuel every couple weeks. Same thing on my lawn mower, holds 10 gallons but only fill half way so I have to add fresh fuel more often, never had any issues this way.
-
In a nearly empty tank moisture and water in the fuel can cause problems - rust in tank.
Even though steel tanks have some kind of protective lining in them over the years rust can develop. Had that happen in my motorcycle tank, used a POR15 kit to fix it.
Got some before and after pictures if anybody is interested.

Interested!

Really good pictures and that really works!

Very common issue on motorcycles due to long term sitting over the winter months. If I am not going to use something over the winter I always give the fuel a good dose of fuel conditioner before storing, then add fresh fuel in the spring to get them running...so far so good!! Probably will never have that issue with the 450i as I am using it at least 3 out of 5 days each week if only to take a ride around the neighborhood all year long..
-
I use only non Ethanol gas with Stabil in all my small engines and old jeep and I run battery tenders on all batteries for 2 hrs each day on each battery. I have batteries that are 5-7 years old. Just my .02
-
Unfortunately not any non ethanol gas in Maine.

Check at any Marina, most have it because the ethanol likes to absorb water and causes a lot of problems for marine engines. A bit pricey but cheaper in the long run, for my $$$.
-
So dead battery issues acting up again. Had it on a battery maintainer for the last 2 weeks. Started up fine but then shut it off and wouldn't start. Anyone know of a deep cycle utv battery that will fit?
-
Keep in mind it is quite possible that your battery was severly hurt when it ran down in the beginning. These batteries are not designed to be dropped below a certain percent of charge and if they do they never recover except for extremely short periods of time. Then again you may just have a bummer battery. If you have a good electrical shop in your area ( alternator/generator rebuilder) they should be able to load test the battery. Actually they are not that expensive to buy a new one, keep the receipt and if it goes out you can always take it back. Beginning to sound like a battery that has been run down to far, many lesser expensive auto batteries will do the same thing, NO battery likes to be taken all the way down..it will kill them. Keep us posted

Thanks I replaced it with a gel cell battery. It turns over a lot better and runs great now
-
Glad to hear..let us know if that was the issue after all.

What battery did you buy? CCA?
-
I'm not sure what type of battery. I know it's 310 cca. I'll look at the battery as soon as I have a chance

Yes I did forget. Busy season at work, and building a house. Priorities. I'll try to look this weekend
