I have a Yamaha warrior 350 and it has a brand new head and piston set. The piston has some scoring on the sides so I bought a new piston kit and it should be here tomorrow. The bottom of the cylinder head still has the cross haching on it but the mod and top don't and still looks good. Do I have to rehone it or no? No would be a great answer LOL.. need help. Also if I do is there another way to rehone it without a honing tool.. don't have one..

What is a good option for a 13 year old that is dying to get her very own atv to ride? Thanks in advance for your recommendations. I currently own a Polaris Sportsman 570 and have been happy with the Polaris sportsman line but have ruled out other brands.
So few months ago I acquired a 01 Explorer 4x4 (think its a 350 but not sure)
Anyway the owner said it started reving very high, shut the key off and still kept running
until finally he shut off fuel and it finally died. During the run away he said the exhaust got
red hot and has melted plastics to prove it. Said some thing flew out the tail pipe, I kinda figured
it was the top of the piston. Anyway finally got around to looking at it (have a lot of other projects in the works)
and checked the compression, Shows about 40 psi. Can hear air coming out the carb while rotating the motor over.
Gonna pull it apart eventually, don't hear any noises or binding in the stroke, You think the piston came apart?
any horror stories of these and is it worth my effort and money? Don't really have any money in it yet. Thoughts? Az

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 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??????????????
I am looking for some help. I just bought a 2004 Can Am 400 quad that had sat for 2-3 years. I can start it if I spray some gas into the carb but it only runs a few seconds. I haven't been able to get it to continue. Any advice on what the problem might be and how I might follow it would be very much appreciated. It had about a quart of gas in the gas tank when I got it. I siphoned that out and put in new gas. This is my first quad so I'm quite new to this.
