posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

I need to figure out how to clean/fix or replace my neutral switch assembly On my 2008 Yamaha big bear 400 as generally the neutral light doesn’t come on when it is in neutral. To get it to come on I have to wiggle the foot shifter and hold it in just the right spot.
I have googled it and can’t find much on the 400’s. I can’t find a service manual online and the parts manual is super vague.
I think it is in the right side engine cover area, but not certain.
Any help would be great. thanks

Hello again guys ,. I have a Quadmaster that has a very bad lean to my passenger side wheel. I replaced the a arm bushings with no change in the lean, I see no bent parts and no adjustments available. It's always been there since I got it but became really noticeable when I put the lift kit on it. I'm going to add a picture of the problem if allowed.

As stated above working on a 1999 Suzuki LT-F160. I think I’m having trouble with the carburetor. I keep fouling spark plugs. Full disclosure, I did make a poor attempt to “rebuild” the carb (that’s why I think that’s the issue). No idea if the new parts are at the correct “settings” (gaps and such) I believe the starting point is 1.5 turns from bottom out on the adjustment screw (is there another adjustment I don’t know of?). Doesn’t feel like I’m getting gas drawn through the carb (clogged jet maybe?), the plug isn’t wet at all (assuming why they’re fouling?) Not a great deal of experience working on carbs and not having much luck on finding a lot of info on the 160’s.
1st- by chance can I swap out the original carb (13200-02C03) for an LT 250 model (think the HA01050). They’re only about $30 apposed to $200. That would at least narrow down if it’s a wiring problem or carb issue.
2nd - The wiring has been minipulated at least a dozen times (before I acquired it, my cousin got it from a buddy kind of thing). Hopefully don’t have to dig into this too much as it’s currently a bit if a mess.
I was told it ran last year...
Any imput would be greatly appreciated
Pretty good video on the history of Suzuki ATVs if you are interested in some ATV education. Starts off from when three wheelers were the norm.
Suzuki, A company with about 100 years of manufacturing history is company built on bold innovation and the courage to push forward with new ideas. One of these new ideas was created in 1983, when Suzuki invented the first four wheeled ATV and introduced it to the world. At the time three-wheeled ATVs were the norm, and Suzuki’s four-wheeled ATV the LT-125 created an al-new vehicle category and literally changed the industry.
