Im new to the forum and the quad I just got. I want to change oil in in. Its almost impossible to find anything on-line. I know it takes 10w40 and know the oil filter location. What oil should I use? Is there a cross reference for oil filter. The closest dealer to me is an hour away. I have NAPA close and like the WIX or Napa gold filters. Also is where can I get a Manuel for it? Thanks

I have a honda trx200 and it starts fine when I use the starter button but won't start with the pull cord.
Hey guys, new here, but haven't found ANY answer to my specific problem on a Suzuki dedicated ATV forum, so here's to hoping!
I acquired a 95' Quadrunner 250, 4x4, (LT4WD) for practically nothing with no spark. The PO had tossed in a used stator which didn't fix the problem... so I went all routes (though cheaply) to narrow down the initial problem of no spark.
Plug, coil, CDI (caltric) and stator w/pickup (caltric) were purchased and installed. And it RAN, but bogged horribly and would not rev past 1/4 throttle.
I checked fuel flow, vacuum lines, all the normal stuff, no issues. I decided to check the valves and cam... well, there was one problem. The cam was 1mm under the lowest spec in the manual. So, in-came a new cam, Stage 1 Hotcams... also threw in a new set of shindy valves, lapped them, replaced the valve seals, and the timing chain.
Back together again (w/stock airbox and new oiled filter). Now it idles even better, still boggs at 1/4 throttle, but will rev past it if you hold the throttle open for a second. Ahaha... success!
So I was able to ride it above 1/4 throttle once I had momentum... could shift through the gears, all was good as long as I kept it over 1/2 throttle. Took a long enough ride to break in the cam properly at least so I won't have to worry about that.
Now, I start fiddling with the carb. It's clean as a whistle, stock, with stock jets (new replacement Mikuni jets). Same problem.
I start thinking, maybe this is fuel related and the bike is having an issue transitioning from idle jet to main jet... so I LOWER the needle by raising the clip 1 spot. Now it revvs up in neutral with no bog, but it boggs about the same trying to ride it. So I move the needle down again with the clip on the top slot. Better, but still has a bit of bog at 1/4 throttle.
The last bit of advice I got was to ditch the CV carb... so I sprung for a brand new Mikuni VM30-83 round-slide. Bolted it up, blew into the vacuum tube to fill it with fuel (no vacuum port on this one) and she fired right up... but there is still a bit of bog, it's just masked by the fact that I'm not waiting for the vacuum diaphragm to open.
So I feel like each little step brings me closer, but not perfect. I'm now wondering if this is still in-fact a carb tuning issue (I have some jets I can fiddle with and maybe lean-out the idle jet a little.) OR if the cheap-a** Caltric Stator/Pickup is what's causing these issues.
I have a 95' KingQuad with 400 miles on it... like new.. runs like a top... I've tried both the stock QR and the Caltric CDI boxes on it, and it revvs up and runs like a champ.
The only unknowns between the two systems are the carb, and the stator/pickup. My next step in troubleshooting is to rip apart the King Quad and test it's CDI on the Quadrunner... but considering there is no change to how it runs I doubt it will lead to a solution.
HOWEVER... I tried the stock CDI just recently after running the Caltric this whole time, and the bike runs like garbage. Hardly idles, and won't rev up at all. So, that is my one smoking gun telling me that it's either the pickup coil or the stator itself.
Has anyone had a problem even CLOSE to this? I can't image the carb would be causing this many issues, especially going to 2 different ones, both with stock jetting to OEM, and exhibiting the identical symptoms... the only change is when different CDI's are plugged in, or when the needle valve leans out the mixture.
Also, I checked the piston, rings and bore when I had it apart and they're like-new... no scoring, rings are loose, cylinder is still round and has honing marks still int he bore. Stock piston, stock bore size and it has 160psi compression. Battery is brand new, and I've tried 3 different R/R's, none of which change any symptoms, but slightly vary the charging voltage by .2-.5 of a volt depending on which unit. Also tried a new coil which changed nothing.
ANY help would be appreciated. Too much invested to not get it running right.

I know...I feel stupid for asking. I find it impossible to use the thumb throttle with my thumb when I have the bars turned full right. I have to reach across the top and grab the throttle from the front with my fingers. It isn't very smooth and I can't help but think that there must be a technique, mod or adjustment for this. How do I get past this?

Can anyone point me to a good set of instructions for changing front diff oil on a 1987 Suzuki LT4WD? I can almost guess which bolts are drain & fill... but I've been wrong before... 😆
I found some partial posts on other forums and they linked out to dead images and whatnot. Any help appreciated.
This thing is running pretty good, got the front brakes back to life, electric start works fine, seat cover fixed up, plastics stitched back together...

I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?
Hello, well back to where I was last year with this carb. Took my 250 to the mountains for the first time this year and blue smoke, too much gas again. I can't believe that this carb gives me this much trouble. Seems like the choke is stuck but the cable moves freely. Anyone else ever experience this issue? Do you think a new choke cable would maybe resolve this?http://www.quadcrazy.com/atvforum/images/smilies/arghh.gif
OK it was the choke. Put on all new cable and plunger and she is running 100% again. So now the question is, is the carb getting worn out where the plunger needle goes in the small hole and when I use the choke the needle end doesn't get lined back up with the hole?? We'll see how it runs and now that I know what the issue is I can always pull the choke plunger out and reinstall if I start having this issue again.
Having a strange issue with the headlights on my Kodiak. Noticed there are no high beams, and when I switch back to low beam the lights stay off. The low beams will come on, only if I go from off to low. This is what I have going on:
From Off to Low - Lights Work
From Low to High - No lights
From High to Low - No Lights
Back to Off and to low - Lights work again.
Just curious if anyone has had a similar issue, or where I should start troubleshooting.
i have a 2009 grizzly 700,replaced the fuel pump and filter,replaced the spark plug and checked the air filter for a mouse house! it runs then shuts down,wont stay running,does the fuel line need to be primed and air free to run properly or am i missing something obvious??????????????
