Its in pretty rough shape and its gonna be my first atv, I worked on bikes before but nothing to do with quads. Anyways the quad has some problems and im tryna figure out what to focus on first. So the U joints i think are shot. The bike starts first try every time ussually have to give it a lil gas with the throttle and revs right up, idles fine but its running REALLY rich 3 starts and my brand new plug was pitch black
Bike is L model
Its using the original mikuni carb but im not the best at fixing the carbs and wondering if there is anywhere online that would be able to either walk me through it or help me with it i didnt see a air mixture screw so it seems like im gonna half to open it up and adjust like the float and a couple other things
Hey I have a 07 king 700 there's lots of times that the quad will stall when the fan turns on also have to bump motor 2 or 3 times before starting to start it (makes fuel pump go on 2/3 times) anyone having or had this issue?

Hi Guys, I'm a newbie but pretty handy with a DMM (controls technician). I have been fighting a junker quad i picked up as a project bike, was assured it would run if I replaced the battery and cleaned the carb. I replaced the battery, rebuilt the carb with a OEM kit. FIxed all my switches and foul played circuitry from the last guy.... So I could get it to start long enough to test the quad, it seems okay from a trans/engine point. However I couldn't get the carb adjusted to idle to save my life with the idle air screw or the thumb screw on the card for the slide. I took it to a friend who is much more familiar with yamaha and quads and he double checked my carb rebuild all was fine, he adjusted the float to make the fuel not overfill which i missed.
He pulled the air intake, got it started and couldn't get it to idle with or without air filter. We started looking at the spark plug (new) and he tested it with a spark plug clamp meter, tested good, pulled it and grounded and it had spark but he felt it was weak. I order a working used oem coil to try the easy things first. When I ohm out the coil on the quad with my Fluke i'm seeing .4 ohms on primary (ground lug to male connector) and 18K ohms on secondary (inside boot to ground lug). Seems like this forum is full of bear trackers so I'm hoping someone has some ideas to help me figure where to go with this. His thought was he know I ave fuel and he knows I have air, spark would be next. I have spark but possibly weak. Thanks

Hi im new to the site. I have a 99 sportsman 500. I has been sitting for about a year now. I bought a new battery for it the other day and now i dont have any power to anything but the winch. Any help would be great. I already cut the pouch and checked voltage on both sides of the circuit breaker.

I just recently bought a 1994 Yamaha Timberwolf 4x4 from a buddy who had the wheeler sitting in his garage for 7 years. I got it home and fired it up pushed it out of the garage and tried to shift it and it wouldn't shift. First it would click like it was shifting, but the wheeler wouldn't move and when I hit the gas it revved up like I was in nuetral. After trying some more it became stuck in 1st gear and wouldnt shift at all. But it later broke loose agian and acts like it is in neutral again. I took the motor off the machine to make it easier to work on.After asking friends they were convinced it was a clutch problem but after opening up the casing for the clutch I don't see anything out of the ordinary and am concerned that it may be a transmission problem. Any help would be greatly appreciated thank you.
Have a 2002 Polaris Sportsman 700 that only has 34mi. on a carb & ring job.
Cut the gas off today to drain carb.Now engine will not idle.If I open throttle will run,but let off & will cut off.Can screw idle in with no change.
What happened? Why did this happen when fuel ran out?
Please help me,my ATV is a daily driver.
Looking forward to posting some questions on here, doing some reading on here, and enjoying the company of others.
So I bought a 1994 Yamaha Big Bear 350 4x4 from a buddy of mine for $1,000. He has had the ATV for about 2 year. No rear problems when talking about the motor. It has failed to start some, and unfortunately it does not have a pull string. Not sure if that is something I can add on later or not. But we traced the issues to the starter and replaced it. Now it starts easily and has a new battery and starter that he bought .
Issues I am going to be working on, and asking questions about:
Hours display is broken and doesn't show anything at all
Would like to possibly add a speedometer at some point
Rear brake doesn't work until the pedal is all the way down to the floor, and then it engages, doesn't really brake. I'm thinking this is a simple adjustment
ATV pops and clicks when turning. Was thinking CV axles, but not sure and want to be 100% sure before I order replacement parts
Need to learn the braking system better. It has two hand brakes and then the pedal brake. What's the difference and how do they all work together. Assume one is a hybrid brake that engages both front and rear at the same time, but not sure
Need to clean/paint the hubs
The shifting is tough and some times requires more pressure than I'm comfortable with. Not sure if it's lubrication, or an issue with the linkage. Need to learn that too.
Having a hard time finding a manual online, need to buy one probably
I have around $500 to invest into the ATV. I am hoping this will take it back to really nice riding condition.
Any thoughts on the above issues/concerns? I plan on using the search functions as well.
Looking forward to hearing from you all.
