So my front hub broke, I’d like to put aftermarket on. Hard to find new oe ones. Please help. I’m new to all of this, I have some car knowledge and try to apply it
By Dra O
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

Hello. I got this fourwheeler to fix for my buddy. It wasnt starting at all when I got it so I opened the valve cover up and checked the timing and the timing was way off. I set the timing bolted all back together and it started. It only stays running with very little throttle applied. There is a weird noise coming from the engine and it smells like its burning and also smokes from the headers. I posted a video idk how helpful it will be but I need some advice on the next step. I want to say it's the piston and rings, but I'm not too sure was also thinking something was up with the valves. Thought I would get some advice before trying anything. Thanks!
these are what i have in my collection ... always looking for more

I've never done this before but after reading a few thread I decided to check my valves for the first time and to my surprise it was much easier than I thought.
My bike is a 2005 Sp 500 HO.
I first pulled the seat and the right side panel off, and that's it! It wasn't too bad to get at.
Next I pulled the spark plug out and removed both the head cover ( 8-8mm bolts)
then the side cam cover (5-8mm bolts).
Also remove the plug in the recoil cover (14mm bolt) to see the timming marks.
Next I turned the engine over with the pull cord untill it was at TDC of the compression stroke.
The best was to tell that your at TDC of the compression stroke is to rotate the engine until the
timing marks are parallel to rocker cover gasket surface.
The cam sprocket locating pin will be facing upward directly in line with the crankshaft to camshaft center line.
Now fine adjust by looking into the timing hole in the recoil cover and line up the upside down "T" on
the flywheel into the center of the hole.
Now using a feeler gauge, slide the .006" (.15mm)blade between the top of the valve and the bottom of the adjuster and adjust accordingly
To adjust, Loosen the locknut (10mm) and check clearance with a feeler guage. Clearance should be .006" (.15mm) for both, intake and exhaust valves. Turn the adjuster with a stubby flat blade screwdriver untill the proper clearance is achieved then tighten the locknut (5.8-7.2 ft. lbs) while holding the adjuster in place with the screwdriver. Re-check the clearance with the feeler guage one last time and re-assemble the covers (72 in.lbs) and plugs.
The only thing that i noticed was that I had to clean and silicone the side cam cover other than that I found the whole process rather simple.
I'd give it a 4 out of 10 on the skill level scale.
I hope this helps!
