I'm saying you have to know something about Raptor 700R's and not confuse them with the Grizzly and it's known cold start issue. You stated that Raptor 700R's and Grizzlies both had cold start issues which is incorrect and it was pointed out to you. Every argument you have made has been refuted, I am beginning to wonder if you have a reading comprehension issue.

There is nothing more constructive to say here until the original poster gives us some more info and if what we suggested he do worked for him or not.
There are a lot of things that could be amiss like corrosion or moisture in the TPS connection, a bad TPS sensor or a multitude of other things. It could be as simple as a fuel fouled plug which will spark out of the cylinder but won't fire under compression which is the cheapest and easiest thing to replace, all things that have nothing to do with a cold start issue.

Now if you have something constructive to add be my guest, otherwise further comment from you will result in proving beyond a reasonable doubt you have a maturity problem or just plain don't have a clue. Either way I am done responding to you unless you have something constructive to contribute.

 

I don't care if the Grizz and Raptor have the same EFI. All I know is I never had this problem til it got cold. It wasn't due to me giving it throttle causing plug to foul. If the plug is fouling now it is due to the electronics itself. I got the battery charged but have yet to get a plug and try and see what happens. TOO COLD! I will let know what I find in couple days. Odd how it is backfiring though after it cranks over for a few seconds.

 

The backfiring while cranking is what leads me to believe it could be a fuel fouled plug, Also something to be careful of is the type of battery charger you use with the OEM AGM batt just in case you didn't already know that. Use a trickle charger only a high amp charger will ruin it. Let us know if the fresh plug takes care of it.

 

The backfiring can be caused by many things. The first and foremost in this situation would most likely be raw gas building up in the combustion chamber. Could it be due to low/no spark from a crappy plug or could it be your TPS crapped out and its dumping in way too much fuel? We/you won't know till you put a fresh plug in.

 

The backfiring after cranking is almost certainly a fuel fouled plug. I have had pretty extensive first hand experience with this. I went through several plugs under all temperature conditions, due to my inability to let the machine warm up before I hit the throttle. Especially under the first few seconds of the engine starting up. If you didn't do this, ok, but try a new plug and sit on your right hand while you turn it over it just might solve the issue. Not saying it can't be an eletrical system problem just try the plug since I know that fixed it for me every time, without exception. Sparking on the cylinder does not mean the plug is not bad!

As for JLsparky,
We can all appreciate that you are an active member of the online support community but reading and quoting a couple dated tid-bits and recycling them doesn't do anyone a bit of good when it is inaccurate or doesn't apply.

Fuel pumps: unless you have one of the first 1000 or so rolled off the line, this doesn't apply. I have one of these models, it is NOT a cold issue. It is a hot machine start issue after the pump basically vapor locks. It can be fixed, it can be replaced, it is RARE. I ride in all temperatures and have yet to replace mine. Starts at -15F no problem.
Fan issue: connector under the seat can come loose, or is loose. Take off the seat and put it back together.


Let us know if the new plug doesn't solve the issue, a lot of folks know a good deal of info on the 700 and can be pretty helpful!! Good luck bud!

 

You dont need a low amp charger you need a 0 amp charger. Running any amps to your battery at all will destroy it. If you have a propane or electric garage heater try and heat the quad up. There might be condensation that froze in the fuel injectors or maybe the electronics.

Im done arguing with these other tools, im just trying to help.

 

Man Kev whats with this hate for Raptors. I thought with Banshee's being Yamaha U at least would respect. Everywhere I turn I see U talking bad facts about Raptors and U don't even own one! Maybe if U just stuck to giving advice about Banshee's and let the ones on here who know what they are talking about and RIDE/OWN Raptors, we wpuld have theses guys back up and running at the cost of a new high performance plug rather then thinking of replacing an EFI that has no problems.

Oh by the way my buddy has a question about his Banshee, It seems that since I have got my Raptor he has to keep picking sand out of his teeth since he is now always second best!

 

So, will a stock Raptor take a stock Banshee?
What are the odds of a Banshee being stock anyway[img]i/expressions/face-icon-small-tongue.gif[/img]

 

My Raptor with the 3mods will take my buddies Modded Banshee, but can't say what would happen stock.
