      in this thread, I want to discuss how 4-cycle atv engines work- what the different types are...  how they are set up and which you prefer.  To start off, are the cams on ALL atv 4-strokes powered by a cam chain?  I know that on say a lawn mower or logsplitter engine, the cam is turned by the tappet, pushrods, and valve rockers.  Which is better and why?  Chain-driven cams or pushrod-driven cams?  Are the pushrods just an old version and everything is transforming to chains or the other way around...or not at all?  Just looking for some explanation, history, and downsides/upsides...

      '11 Grizz 700 here.  Since I've got some warm weather these next couple days I've decided to start the bike after about a year of just sitting.  Took out the plug and sprayed a good amount of fogging oil on top of the piston to help lubricate things.  After about a minute of letting it soak I stuck my air line tubing in to suck out the excess, but it seems like I didn't get nearly as much in return.  Repositioned the tube enough so that everything that was gonna come out pretty much did.  I'll probably shoot some compressed air down the plug hole before doing the start just to make sure it's all out, as well as cranking it for a second before putting the plug back in.   How long would it take for a bit of standing fogging oil to seep past the piston rings, and where would it go?  I guess into the engine oil?  The oil was fairly new the last time it was started but I'm sure it could stand to be changed after sitting for so long.  If much of this fogging oil got into the engine oil should I do the change before the startup?

      Haven't been tracking because I was down with a cold. And it really sucked because we had several storms come thru and put down some nice fresh snow. But it's all good now. Except now, the temps are really going to start going up which means the snow is melting fast. But I got out on 27 Mar & the tracking was AWESOME !!! Hope you enjoy the video !!!

      Hey everyone,been dealing with quads since I was a kid,now I have a son who loves my raptor 700 and had gotten him an electric power wheel quad but it didn’t cut it for him.so for his birthday “xmas eve” I picked up a used 2002 quadmaster 50 for 500 bucks. It started and moved but needed work..
      got it home drove it for a few feet and it started bogging down and would shut off.
      so I stripped quad down to the frame cleaned it up as best I could without removing motor from frame.
      replaced top end new head piston rings etc cheap kit off eBay along with carb that will be here today.the filter that was on carb was degraded and soaked with gas. Also new cylinder doesn’t have vacuum line so how do I block that off without getting new petcock valve?
      tightened chain.
      guy said quad doesn’t take oil as it’s a closed case right then I knew the guy knew nothing about the machine. So I changed oil,was black and thick and just nasty like sludge.
      suspension in rear seems good but the fronts are very stiff,any way to adjust these or should I get a new set?
      also upon stripping everything down I noticed the exhaust restrictor was gone so without that do I need to update jets in new carb,old carb has original jets??
      and also I’m new to cvt tranny so how would I know if it’s bad etc?
      sorry for all the questions just want to make this thing safe for my 5 year old knucklehead.
      added some photos of my current progress didn’t take any inbetween cleaning everything though 
       
      please any info will be appreciated.
      i haven’t rebuilt a quad since 1999 when I had my blaster and my buddies had other 2 strokes I was the mechanic with no knowledge but always seemed to get things right!!
      also if you notice the old head looked chipped and damaged and I’m wondering if those chips made it into motor how would I go about finding them?i would think by now they would be chewed up? I did not strain oil that I drained but might do that later when the kids are sleeping and I have time to check it without kiddo seeing!
