Question about water pump impeller

Is the carb on the machine a Mikuni or a Chinese knock off? The 2001 Sportsman 500 was the first year of the HO series had the same bst40 carb as the 2002,2003,2004,etc..

Looks correct. The kit won't say it's for a BST40 carb,just the year model that it fits. Look over this pdf fuel section from the manual. Early model 500s used the BST34 carb.Later model(2001 and up) used the BST40 carb which you should have.https://www.google.com/url?sa=t&rct=...U2gGlaHJWSIlbA

Flywheel,stator and plate and even the recoil cover can stay on. You have to get the cam at tdc. Mark the head inline with the index pin. Remove the tensioner, thermostat housing(to get to the cam plate) cam plate and rocker arm blocks. Remove the sprocket(without moving the flywheel and let the sprocket and chain drop down. Pull out the old cam,in with the new one and align the sprocket with the cam. Wiggle the chain if you have to but not the flywheel... The rest is on the post you found.

Sprocket and chain will be caught by the chain guides,won't drop down far.Once the new cam is in,sprocket and chain timed up and cam blocks are installed,check/ adjust the valves since you're still at tdc.Then install the tensioner(plunger in)install the spring and tensioner bolt. Turn the engine over slowly and the tensioner will self adjust.Button up the rest of the machine,fill with coolant,leave the radiator cap off and bleed the system while at an idle. BEFORE you take the old cam out run the engine at an idle until warm. Drain the oil and remove the line at the oil tank and clean the screen. Replace the line(teflon tape on the threads) and new oil and filter. Pinch off the vent line at the top of the oil tank and run for a couple minutes when the new cam is in. This helps prime the pump quicker.

Decided to have my local guy do the cam. He said $50. I've been working doubles so haven't had time. I tried putting the gas tank back in so I could drive it into my truck, I can't get the two tabs in the front of thes tank to line up with the slots. I tried for 30 mins with no luck. Am I missing something? It won't bolt in unless both tabs are in their slots/holes

Yes you're missing something just like I did on my first encounter with this style tank when they came out..The older model tanks fit into the frame cutouts.This model tank tabs go BELOW the frame cutouts,not in them. Just angle the tank down and push forward. I felt like a fool fighting with this myself until I figured it out the first time. At least I'm not the only one to do this. Plus for 50 bucks I'd let someone do it to..
