Ok, I have my new 350, and realize before riding too much I need to adjust the carb. Rejet if needed. Luckily it came with a ton of jets.

So I have been reading on the best ways to jet your carb and get it adjusted nicely. I do plan on running a little rich as to hopefully extend the Engine life (as long as I can keep the carbon build up down).

But it had me thinking. EFI is sooo much easier and nicer and faster. Why can't I put EFI in a 350? Has anyone tried it? Not talking about replacing the whole Engine, just adding EFI, since it has a battery, it should be possible.

The reason for this is I really like to just get in and go, and be able to not worry if it is a humid day (can be 90%+ in MI) or a cool snowy january day (10% humidity and 10 degrees)...

Anyway, soliciting thoughts, ideas comments.

Tons of info.

Ok no offense but EFI on a ATV is for morons that are too dumb or lazy to adjust the jetting on their carbs, I adjusted the jetting on my Pilot 2 times since I have owned it and was running the Honda Engine, run it from 30 degrees at 500', run it at sea level 60-90 degrees, run it as high as 2500' at 95 degrees, I did the dual intake and prefilter mod to the air box and adjusted my jetting for this mod then if it got cold I just used duct tape to cover one or part of the openings in the air box reducing air flow compensate for colder or drier air, this riches up the mixture, on hot days I let it run fat, the only time it would smoke is on real hot humid days, 90+ 80%+ some expurts will go on a long rant about performance losses bla bla bla to justify their lust for EFI but their machines were/are always slower than my Pilot when the jetting was off so whats the point..

I have never fouled a plug in my Pilot, I ran one spark plug for over 6 years, I replaced it with a NEW plug because the center electrode had become worn to the point the edges were rounded off, sure I could have sharped it with a file and a stone but after its long life why bother...

Is your 350 stock?

Whats the plug look like, do you see any smoke out the tail pipe once the Engine is warm ?

Most stock 350's I seen can run the factory jetting even after the air box mod and they perform really well.

Oh forgot to add, a properly jetted carb will out perform a EFI system EVERY TIME after all these years they still don't have them refined enough to out perform a carb.

OK ok... forget the EFI... I think I have just been subjected to very poor running 2 strokes all my life, because this one is a dream.. Sits overnight, starts first or second pull the next day, etc. (still haven't picked up that battery...)

You can easily get it to start that way....

What is the starting procedure now?

Since I changed out almost all of the fuel lines? Pre-ride inspection , of course, then turn on the fuel valve, pull out the choke 1/2 way, pull till you hit resistance, then pull hard, not fast but steady, and it just starts idling...

How many pulls does it normally take to start?

I know on my Pilots and 250 Odysseys I have owned in the past if you let them set a week they are harder starting, once you get them primed they fire right up with little or no effort.

On a side note have you noticed guys with the EFI are always constantally "jetting" their EFI, not all but the same group or amount of gear heads that use to bitch about jetting are now spending hundreds if not thousands (lap top) so they can "program" their EFI, I have run across many web sites with sections that contain "maps" the guys trade like mp3's then waste a day programing them and testing them in their EFI powered machines... The more I read the more I get the feeling its more of a game than anything lol

All the years of hearing guys bitch about spending 30 bux in jets now are spending hundreds of dollars so they can "program" their EFI or "jet their carb" same end result, one first hand experience with this was when I was at Dumont dunes a buddy of Nukems spent more time in one day "programing" his EFI than I spent in the past 15 years jetting carbs.. bottom line is EFI is only gas and go if you want to remain stock, just like a carb if you do even the slightest mods you need to jet your EFI

I tried a EFI system for a pikes peak car, it didnt ever work verry well. You have to have a really accurate crank position sensor, a high pressure fuel pump, and a computer to advance and retard it. After spending months and a couple thousand dollars. we came up with a dial-a-jet system for a marcuni carb to compensate for altitude changes.

My idea for pikes peak was to use several dial-a-jets then cut off the fuel flow to them one as a time as altitude increased.

Any pics of your Pikes Peak adventure?
