How is everyone? I would like to know if there is away to convert a 2002 Sportsman 700 from a carburetor to the EFI? Any help would be appreciated.

 

Welcome to the forums.

As with any project, it could be done. But, it seems like it would be a lot easier to sell the old Sportsman and just buy a new/er one with EFI.

 

I would, but I have had this particular Sportsman since I bought it new. I have become to attached...

 

Well, any project is possible. You'll need the three basic "T"s.

Tools
The wife not knowing how much it all cost

 

You would need to change the wiring get a ECM the buy the throttle body, intakes and injectors, it would be more work and cost than its worth.

I fish with two guys, one has a 700 carb and the other a 700 EFI,there is not much difference between the two other then one needs choke on cold starts. Is pulling a choke worth that much money ,time and labour to you?
I ride both ATVs and can,t tell them apart while riding.

Just the Throttlle body,position sensor and ECU would cost close to a grand. Not Even sure if the 700 EFI uses one or two throttle bodies.

 

Thanks for all your answers, I think I will stick to the carb... to much work for no gain

 

You should be very thankful that you have a simple carb instead of EFI.

 

I will not own an EFI model. The carb model is simple and cheap to repair.

 

No power gain also, the 700 carb and 700EFI are both rated at 44hp. If you want a cheaper upgrade with noticeable improvement,get a clutch kit or pipe, or 42 TMX CARB or high Duration Cam. or all at once. From here.

They have 3 stage kits ranging from $250 to $750. #1 get you 48hp

#2) 50 HP at 6000 RPM and offers superior throttle response in midrange.

#3) 54hp

 

Ok, good good. What do y'all think about the rebuild kits on ebay? And what pipe do you recommend?
