I have a 2001 yamaha yfm350x and it has a brand new top end, new carburetor (stopped the leaking problem and is now getting gas to it), new CDI box, new stator, handlebar switches work, off-and-on switch works, new starter solenoid (works), new neutral relay (works), ordered a new Rectifier on its way, good strong blue spark. Has compression, valves are right. Timings is right and is TDC. When I try to start it it just makes a loud popping noise like its backfiring but it's not because its not running when I push the throttle all the way and when i barly push the throttle it try to start but won't, so I'm trying to figure out what could be the problem not starting now, Getting very fustrated with this thing and put some work and money into it and it's not still not working. This is the only atv I ever had that I can not figure out the problem to get running. Need help please..

I have a Yamaha 350 in at once to try to fire up but won't. It's getting gas fire air and it has a lot of compression but still struggles to start check the timing it's top dead center valves are good valves are adjusted everything's working but won't fire I put my hand over the carb suck in gas and it tries to but it makes a lot of black smoke. Also when I put my hand over do you carb and tried to start it there's black black nasty stuff in the gas. So I don't know if it's trying to burn too much or what it is the gas tank clean and it anything to do with the gas it's with it firing. Took the spark plug out and it's pure black. What is dried up black not nasty corroded wet looking. Need help to solve the issue

I recently got a 98 warrior 350 that 'needed the carb adjusted' but the reality is it has no spark. I have a new spark plug, plug wire, ignition coil, battery, and cdi box. I checked continuity and took apart and inspected the starter/kill/light switch on the handle bar, and it all looks brand new and checked out. The key switch seems to be working properly, as when off, nothing works, but when switched on, lights and electric starter button work. It turns over fine, and as I just stated, all the lights work. I took all the plastics off and traced all the wires, and only one had a small cut in it, but it was only through the rubber sheathing, not the wire itself (the blue one coming from the stator). I cleaned some grounds, made sure both relays work, and still nothing. I pulled the stator cover and looked at the stator itself, and it looks great. No broken wires or connectors or anything. Still, no spark. I'm at a loss. Where do I go next? Any help is appreciated.

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

There are many ways to install grips and make them stick. The best one, short of having grip glue, is to use carb cleaner. First, clean your handlebars with carb cleaner and a rag, then spray the inside of the grips liberally. The carb spray acts as a lubricant first and then actually melts the grips enough so that it will bond to the clean handlebar. This works great for all but the most extreme conditions. If wet weather is involved, you really need to use grip glue, and in addition, you should follow that up with some safety wire.
