Awesome thanks!! And sorry to the forum, I really enjoy following along with all the threads and giving my 2 cents worth but just havnt made time.. school and all..

Hey so back to this bike.. turns out its sputtering high end and found out the air filter is too restrictive. Also blew the axle bearing so I gotta replace that cause the chain is wayyyy too loose as is. Any help on what air filter would work good on this? It's almost like it needs a turbo haha.
And what's a good plastic cleaner for atvs? It has mildew on it and some pine sap.

Update on the 800- so I'm thinking a crack in the exhaust pipe is causing the screaming noise.. havnt taken the time to find the tps specs yet. I think the belt is almost shot, gonna order a new one.
I'm trying to find the best way to fix the exhaust? I was thinking put one slip on coupling and cut out the welded part.. also put on a 4in lift, starting to look for 29-30in wheels for it without having to pay 1k lol also tryna find a clutch kit for it.. any input from those murders out there would be greatly appreciated!!!
Gotta rebuild the snorkel, had some holes in it. What sealant should I use? What hose should I use?
Here's some pics of the exhaust and lift

So turns out the k&n filter had some dirt in it, flushed it with gas, blew it out with compressed air.
One of the intake snorkel hoses was kinked, cut that out, will replace ltr.
Now bike is running better and idles around 1200-1400 rpm which feels too high. It idled at 800-1200 rpm before.
Gained noticable power tho! I cant seem to find the spec for the tps idle voltage, but I'll check as far as increasing voltage smoothly.
I'm gonna have to do a fair amount of snorkel work. The air box is missing the gasket, and several hoses for the clutches and that intake need to be replaced.
Also, I think the screaming that I'm hearing is the belt topping out on the secondary clutch. No problem, just louder cause the intake and output are snorkeled right up to the handlebars rather than under the gas tank. I topped out the engine going up the driveway and its sounding like normal. Had a backfire fart after letting off, but didnt lean out or anything..

Yes I know! I love Polaris sportsmans

Awesome thanks! Looks like I'll be spending some time tomorrow running thru electrical on the bike...
I want to take an automotive electrical class at my community college this yr.. see if I can gain some know how..

So to me it sounds good low end but seems to race high end and sounds like it's about to fly apart... looked online and turns out this is an ohv engine, not a ohc, so no timing or valve adjustments...
also can anyone point me to a yt video on how to test the speed magneto on polaris bikes? This one and the one on the 500 are dead I believe, but this has also been partly rewired for the rad relocate...
also it seems to be continually losing starting power to the starter as time goes on.. the battery reads 12v and 14.3v when running. But the starter struggles on the first stroke to turn the engine over..
Gonna be a learning curve to figure out the tps.. but I think your right ab it not being right as every once in a while it seems to not have power. Also noticed it seems to lose power at high rpm.
-
Here's a vid of it running at a higher rpm. Just sounds like it's not running right... has a lotta power tho.
-
So everything works except the mph needle. I'll post another vid of me running it around... sounds like it runs rough at high rpms to me...
-
There it is... lol

Video coming tomorrow btw lol
*hearing. Lol

Ok. So I drilled a hole a while back on my 500 and couldn't believe how much more power it had.. the stock exhaust on almost everything nowadays coups up the power in my opinion. No I wouldn't go cut the pipe off at the manifold, but this is a 1/2inch hole in the end of the exhaust. I'll check the TPS as well. Not really concerned with the stock tune as I plan to put a tuner on it anyway.
But yes, yall can hurt you engine by allowing too much backflow into the manifold.

Yea sorry I havnt been on the forum lately.. been working 14 hour days. So it's running a lot better now that I drilled holes in the exhaust to open that up... turns out factory these bikes are tuned rich so now it's really responsive and spunky. Still want a tuner for more power but I'll get to that ltr. So ima do the usual run down... valve and timing check, new spark plugs, and front in alignment as it has a fair amount of tow out.
-
Oh gosh. This is homework for me. Never really caught on to the electrical side of atvs..

So yesterday I picked up a 07 polaris sportsman 800efi stealth edition for 3k. Will lead a pic ltr. In good shape. Here's what's wrong with it:
The rpm needle doesn't work just like my other sportsman... not too worried ab that.
The motor doesn't sound like it's running quite right and doesn't feel like it has much more power than my 500. I'm thinking it needs a tune up and some fresh oil.. but also it feels like it's running rich. It's a little buggy when you goose the throttle and sometimes farts when you let off (like I little backfire out the exhuast). I'm gonna check timing and valave clearence on the motor first but thinking of putting a tuner on it? Anybody got a suggestion? Mainly looking for more power.

Make sure that little lever that the reverse cable goes to isn't jammed with crap potentially causing your issue before taking the bike apart. I had a Kawasaki and the reverse lever got a stick in it and I could not for the life of mr get it into neutral. Took the stick out and works great

Yea in this case aftermarket works great. Bought a $30 dollar one for my Polaris in the spring and still works awesome.
-
i would just guess that either the starter chain is jammed or the starter literally blew up internally shorting the battery causing the smoke maybe? gosh you could make a welder out of this puppy...
-
yea definitely worth cleaning and lubing the connections. works great for hard-to-find bad connections. good luck with that bike!! wiring isnt really my strong point so ima back out at this point..
...and watch and learn lol

is yours done or are your finishing the outside? how do you operate it? pretty awesome tho!
Gotta new bike...

So the exhaust is not rusted like most, and a dual exhaust so I dont see any benefit to an aftermarket or a new OEM because I've heard that there's really not much power to be gained over the dual exhausts. So prolly gonna weld a section in.
