2007 700 efi sportsman HELP

[juur711]

I purchased a 2007 700 efi a few months ago my first polaris sportsman.The issue is not serious but needs addressed this machine has crazy power but it acts more like a two stroke if that makes any sense.the person i bought it from said there were no clutch mods made,but there seems to be a power issue at lower rpm's it does have an aftermarket slip-on muffler (loud as hell)that i plan on replacing with factory dual from an 800 should be alot quiter with decent flow.with that being said i replaced the belt and was wondering if there may be a clutch spring combination that would be a better fit.Really dont care for the wind-up/load-up before power transfer.Any help will be appreciated if i'm not mistaken the primary was blue?

the blue is the stock spring, probably about as mild on take off as you can get, what rpms does clutch engage at?

[juur711]

it ingauges at about 1500-1800 but if you are tring to put on a trailer or even on my patio that has a slight grade it raps up to 3800-4000 before it starts to pull if you get on it a little it goes into powerband if that makes sence

i guess this may be normal but would rather have more low end power than top speed for sure not a speed demon

I have 2 700's and they do require a bit of juice to get going on an incline. Doesn't bother me much. Seems like a fair exchange getween power and top speed. There are a lot of aftermarket clutch kits for people putting on larger tires so I imagine they would allow for more power transfer at lower RPMs.
I don't mean to sound insulting with common sense but you didn't say if you were doing this, so I will mention it. Loading and unloading from the porch or trailer could be done in low gear. That might help. With the 700's it isn't necessary as I can get mine into my truck with 6 foot ramp (very steep incline) in high with no problem. Like I said, if you are already doing that please don't be insulted. I have had to be told some pretty basic things in mytime that I for some idiotic reason hadn't thought of.

I think that when i go stock with the muffler it will be better just sounds like i'm having to gouge the hell out it under mininum load to get it going,then hold on. Its not that i can't deal with it but I worry bout my wife on trails as this will is going to be her bike,her last bike was 500 honda.

[Russ C]

if not using low you should

[AKStew]

Have you checked the belt deflection or that it is the right belt? It sounds like classic symptoms of a mildly loose belt.

IMO I would always use low while loading.
