Do you, by any chance have any spare Polaris scrambler 400L parts laying around you would sell? Mine is a 97, looking for a transmission or parts to repair the reverse gear.
I'm having the same issue how do u adjust the carb to make it run right it runs drives then it bogs down and dies previous owner put new carb Chinese just trying to figure out what I need to adjust
@christian angeles that's where I'm at. New Chinese carb and now the machine won't go over 30mph. In the one video I seen him adjusting the pilot but he cut the camera because he said we couldn't see anything. I don't need to see, I need to hear the change and what I'm supposed to be listening for....
i picked up a 97 scrambler 500 for $100 from an older guy.he took it to a shop had them install a new carb,after they installed it they said it backfired and smoked and wouldnt stay running and told him it would need engine rebuilt.i took the seat off and seen they didnt install the carb all the way into the intake boot.with half of the carb letting air in backfired and cought the carb on fire inside,it melted the slide to the midplate and lucky for them,it still had 10 yr old gas in it and the filter didnt allow much gas to fill the carb,soot on carb and boot shows it was on fire,i cleaned and installed the original carb,fired right up,ran good till the other day,seems the fuel pump is intermitant and the petcock was leaking,installed a new petcock and now it hard to start,acts like its out of gas.can i bypass the pump and just have it gravity feed the carb,i cant find a fuel line diagram for the scrambler,so the lines might not be routed properly.any suggestions?
Have you tried my method? A separate fuel tank to bypass pump? blow back into your lines from the fuel line attached to carb. the screen in the tank could be plugged. google fuel pump images for a scrambler. Thats how I found the diagram. P on pump goes to vacuum on carb. The middle outlet goes to fuel line to carb and the one on the farthest side goes to tank or shutoff.
I dont have any now. If you google 500 even sportsman 500 fuel line pictures you will see where the fuel line go. You are the second person to ask. Maybe I will shoot a fuel line video. On the 500 carbs if its non H.O. there are 2 breather ports on the airbox side. The breather hose is in the shape of a Y. Attach the 2 hoses to the carb ports and the other end goes out to a hole in the frame.
@@TitaniummanGarage My scrambler is a 97, my understanding is these years did not have H.O, however my carb looks like a H.O is it possible someone installed into my stock scrambler?
I just picked up what i was told is a 2003 sportsman 500 ho with all the same issues that you are showing on some of your videos. I have tinkered with and fixed some things. The thing idles good and will accelerate good with the choke on but bogs down and will not with choke off. I have looked for the serial number everywhere and cannot find it. The stator diagram looks like a 2002 with the two, two pin connectors. It has a small cdi box (cu2574) I am thinking that the cdi box might be bad. Do you know where i can find this box?
hey man I have a 1997 Polaris sportsman 500 and it backfires and boggs I've replace the timing chain, the cam shaft the starter and the carb. do you have any idea on what it can be. I posted a video on my youtube on how it sounds if you can check it out that be awesome.
Thanks for the tip on the kill sw adjustment.
I watch too much utube but gain lots of useful information
Many Thanks
Nice find!
Do you think a Mikuni TM flat slide carb would work on these motors very well?
Do you, by any chance have any spare Polaris scrambler 400L parts laying around you would sell? Mine is a 97, looking for a transmission or parts to repair the reverse gear.
I do mostly 4 strokes. Not many parts laying around for 2 strokes.
With the aftermaket carb i moticed the manifold boot is to small for the aftwr market as the stock carb is smaller
Depends which one you got. There is a H.O. which is bigger or the non H.O. which sounds like you have is smaller.
I would like to know we're you located at.
Will you be doing a video on all those work items you said it needed, ie. Adjusting the carb, checking if the head gasket is blown?
I have a couple carb video's and I have a head gasket replacement video. I'm just pulling the plug to see if there is any antifreeze on it.

do you blow both lines back to tank with air?
@@deadwood3764 from shutoff to tank, yes.
Hey man,
Do you have a used flywheel for a 2001 polaris sportsman 500 ho duse?
I replaced my carb on my 2000 sportsman 500. If I even half choke it it dies.
Could u please do a video on a scrambler 500 on we’re all the gas lines and breathers go me and my dad can’t find any other videos

It's not the cdi. Lots of times I either have to replace the cables. Or it could be out of adjustment.
hey, replacing intake rubber from carb to block, do you put permatex here?
No. If it's new it should have a seal on it. I have seen gaskets that come with them. Normally from the factory they didn't have a gasket.
Thanks@@TitaniummanGarage

Can you share the link? Did you check intake boot for leaks? If it's an aftermarket carb its usually set rich.
@@TitaniummanGarage I figured out the problem but know it won’t idle it was the rev limiter I unplugged the black wire and it runs
My Polaris Sportsman 500 HO came with aftermarket carb with rubber plugs still installed. What gets connected to those two ports?
The 2 side ports are breather ports. usually gets a hoses attached.
or left open.
My 01 500 HO from the factory had the left port plugged. The right port has a clear tubing that terminates into the frame on the LH side. Strange.
Is it possible to replace the timing chain on a 500 while its on the frame?
Yes. th-cam.com/video/t4J1XBB3nN0/w-d-xo.html look at about 35.12 in the video
Just put a Chinese carb un sure how to adjust the carb,if there is an adjustment
Are you near nh?
