Need some help. Went camping last week and I was pulling a trailer (about 1000lbs) when we had to go off trail to avoid a bad area. I ended up wallowed in a mud hole with the left tires buried to the top in mud & muskeg, the right side was almost totally out. The left front tire was not spinning. My brother said that he heard a clicking (I did not hear anything). After we got out I watched the front left tire the best that I could when driving in the mud and it appeared to be spinning the way it should. Question #1: When a front tire is too bound up will the visco-lock release itself or will it keep trying to deliver power to the point of failure? Question #2: Since it appears to be working now, do I have to even have to be concerned about it at all?

Hi everyone. Just turned 46 and purchased my first quad. It's a 2016 Sportsman 570 SP. I'm new to riding but loving it so far!

Hey all!

I have a 2011 Outlander 650 Max, with an 800 top end from MrRPM. I'm running a Dobeck AFR+, which for the most part is doing a good job taking care of tuning.

I had the bike out for the first long run since rebuilding, for about 15 minutes on the 5 hour run, the Dobeck stopped reading the O2 sensor. The fuel map kept the bike running fine under load, but she stumbled while trying to idle. I also have a fairly lean idle pretty much all the time with the dobeck setting maxed. Not dangerously lean, but leaner then I would like.

I don't want to have any more down time right now, I'll probably send the ECU away to be tuned this winter. I'm just trying to think of a way to increase the fuel sent to the bike so the Dobeck doesn't have to adjust as much.

I've been told that the 800s my year have bigger injectors, would they be a direct fit, and would they increase fuel sent to the cylinders (when the Dobeck is off, when it is on it should correct with either)?

Thanks!

My Polaris Trailboss will not fire through the spark plug and i have replaced the voltage regulator, coil, and spark plug. But it still won't get any fire.

Hey everyone I have a 2007 sportsman 800 and I am having issues... I have 2 issues, the first issue I'm having is with my coolant.. it seems to vanish and I have no leaks... I've triple checked. I confirmed my thermostat is working along with my fan. I'll drive for an hour and will have to refil my coolant.. I will also get the "hot" and check engine on the dash about 30 mins into my ride. Any ideas?

My 2nd issue is with with my screen/control area. My RPM gage works along with my gear indicator and fuel gage. My odometer and speedometer do NOT... my battery light flashes constantly as well... I've checked my battery and it's full (12.8). The qaud has no problem starting and has had no power loss.

Thanks for any help guys. I'm trying to learn and do all the work on my own and having a route to take would be appreciated!!

Well after trying numerous different solutions to try and fix what seems to be a lean pop at cruise and while reving my renegade 1000, I ordered a PCV to replace my HMF optimizer. It hasn't arrived in the mail yet, but after looking on powercommanders website I can only find 2 maps? One is stock and the other is for a two brothers slip on and stock air filter. Am I missing something or are these the only premade maps available? I really don't have the time or money to throw at taking it to a dyno for tuning, so if someone could let me know if more maps are available I'd appreciate it.

My mods are a UNI foam filter and a big gun exo slip on. I plan on getting a full system and maybe doing some motor work in the future.
