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

Somehow ran my system dry of coolant and didn't know it. Was running with dead battery. i.e. no lights. Overflow hose from filler neck to recovery bottle was melted.
Wheeler is very hard to start after this. Prior; rebuilt the carb and machine ran great. Now I have to slightly hold the throttle at just the right spot while choke is on to get the engine to turn over fast enough to start.
Now once it starts I am getting white smoke coming out where the thermostat goes. I removed while flushing out remainder of old antifreeze and beginning to put in new.
See the video.
Thanks for your input.
Hey guys, Im new here but I recently Picked up a '99 Foreman 400 that apparently just had a top end rebuild. It blows white smoke like crazy and ticks/knocks and seems to follow the rpm's. I haven't done to much trouble shooting yet, It starts and runs like a champ and has good compression. I was just wondering if anyone has any suggestions as to where to go.
Oh ya the top end rebuild the guy did was according to him he honed the cylinder and replaced the piston and rings, my fear is an ovaled cylinder?
Not sure but I think its using oil. The engine always does this no matter how long it runs. The engine was running about 30 minutes in this video.
[/ame]The exhaust will blow out carbon also when reved up.

I was checking out helmets today and I was talking to the salesman today. He stated that DOT helmets are better quality than Snell rated because Snell is a private company. He could of been no more than 25 yo. He also couldnt answer my tech questions about helmets. But was trying to sell me helmets with "BITCHIN BRO" graphics on em.
Doing my own research confused me even more
What is the real world difference between the two ratings and does it matter on the trails?
is a $400 dollar DOT helmet better than a $150 Snell rated helmet?
What are the brands you guys/gals use and why?
Where is a good place to buy them?
Easiness to return them?
Why are my above sentences getting shorter with each question?
