Is a cracked head common with 01 raptor 660"s

Only if they over heat I`d go with OXY`s suggestion or pull the valve cover first and see if one of the gaskets if bad !!

      I recently purchased an 07 Honda sportrax and when I was checking the spark plug I saw the boot was ripped nearly in half. When I removed the plug it was blackened and covered in oil. How can I thoroughly clean the plug hole and remove any debris that is in there? Is there a small tube like vacuum or something of the sort made for stuff like this? The machine my dentist has would be perfect, maybe they do rentals! 😁

      I've had this machine for 2ish years, has ran great up until winter. Sometime during then, I managed to break the exhaust right before the muffler. The summer before it had a hard time idling, but we fixed it by cleaning the carb, and messing with idle. Near the end of last year, the only way for it to fire was the have full choke, and full throttle, and the engine bogged down and you had to keep on throttle for 25mins. Over winter, the throttle had dislocated, and I got it back in place. We got it running, and all was good. Spring came along, and now it doesn't start at all. A fluid is coming out of the exhaust, and I'm told it could be water from over winter. I checked the airbox, and the air filter isn't for this quad, it also is barely sucking air. There appears to be little to no compression, based on this. I'm pretty sure the engine is flooded, as the spark plug produces a spark, but is oxidized. I don't know how the previous owner treated it, or when it's last oil change was. A bolt on the engine has either oil or gas seeping through it,abd was loose. I tightened it and it consisted. The engine is basically positioned in the rear, and it needs a good clean, I don't have a pressure washer, so I can get the built on dirt off. any recommendations on how to get the beast started again?

      This is more of an informational fix I wanted to share..
      My Grizzly has been getting harder and harder to shift this winter and today was completely stuck and I needed to plow the few inches that came down this morning. First thought...oh no, tranny...but it’s winter and maybe it’s iced up. I pulled off the plastic to see what was going on and indeed I did find the drain tube iced up. 
      I took the blow dryer out and de-iced it. Quick fix, I never really thought about the shifter drain tube icing up before, shifts like new!

      Can anyone give me guidance on my issue. I have a 02 Grizzly 660 and replaced the wet clutch, primary shaft, one way bearing.  Today I was riding since I tested and was driving about 20-25 mph and all of a sudden the tires locked up, heard a screeching sound, and engine died.  Didn’t have a clue what was going on, decided to try and restart, engine turned over normal but engine hesitated slightly, started and had to assist with the throttle.  It seemed to do this for a minute then seemed to straighten out.  Got home, pull clutch cover and test drove to witness clutch operation and everything looks and sounds perfect.  Could not duplicate.  Please help.

      If we had a dollar for every time the question “Which is really faster, the 700 or the 450?” shows up in our inbox, mailbox, or voicemail, we’d be putting this magazine together from a bungalow on a barely inhabited tropical isle named Quadhama.

      I have a 01 raptor and recently had to bore it out to a 686 because it sucked in a bunch of sand. Now I have no torque or power in the first third of the throttle. I am hoping that someone else knows what is going on with it
