First of all sorry I have been MIA here for a while, been busy with school and work. I'll try and reply on some other threads asap, but posting this one because I just picked up a 2017 sportsman 570 before the new year and popped a boot on it going through a mud hole. The former owner had aftermarket axles on it to accommodate the 4in lift and idk what brand they are but they're skinny as heck and idk what boot to buy to rebuild with? It's the rear right lower boot (under the brake calp.). I'll post some pics when I can and sorry again I've missed yall on the forum!

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

A friend of mine has this particular 4 wheeler. It sat in the garage for about a year, so I redid the carb, cleaned the tank and installed a new petcock. So far, it cranks right away whether its button started or pull started. So I have a couple of questions concerning the carb and air filter.
1. Is this a cvk32 250 or 350 carb? As the air fuel ratio adjustment is different according to a cvk document I read. What's your adjustment setting? 2 whole turns and a 1/8 or 2 whole turns and a 1/2? Comparing the old setting on the carb to the new setting (and where the needle sits now), makes me think it was way off before.
2. The Air filter cover, gasket, air filter and plate element are all missing. So I was thinking of removing the hose that goes to the air box and put one of those K&N style looking filters and be done with it. So my question is.. will I have to readjust Air Fuel screw or just adjust Idle?
It's just going to be driven around the neighborhood.
Thanks in advance for any info or help. Y'all stay safe out there!

I have a 2001 suzuki quadmaster 500 4x4 that has a rev limiter when it is in any gear other than neutral, i have already fixed a bunch of stuff on it and would love to just bypass it if anyone knows how. Thanks for any help.

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
