exhaust bolts

I need new exhaust on my 92? 250 Timberwolf. I am afraid that I will snap the bolts off in the head when I try to loosen them. I was wondering if it might be better to warm the engine up first as the aluminum should expand more than the steel bolts

Are they  bolts  or  studs? Usually such  as exhaust  manifolds  or   pipes  in the  case of   single  cylinder  engines are  connected  using  studs into the  engine  and  nuts  to  secure  the  pipe to  the  exhaust ..   Some  penetrating  oils  will wick  into  nuts ,  studs  or  even  blind  bolts ..  Warming  the  engine  might  help,  but  be  careful  of  fire  after  spraying  penetrating  oil. If  the  stud nuts  or   bolts  don't  break  loose   fairly easily , try  tightening a  little  and  then  loosening .. "rock"  them  a  little  without  over torquing in  either  direction  also  helps  break  a stubborn  bolt/ nut  loose.

      Just picked up a 2003 Yamaha Kodiak 450 ATV. Doesn't run and it's been sitting out in a field for a while faded bodywork, seat's a mess, dead but it rolled so I figured for $100 what the hell, SOLD! I have no idea what could be wrong with it, first thing I guess is hook up a battery and see what happens. I'll likely be back here with questions for the forums collective experience. Live in the Santa Cruz Mts and sure could use a little work horse like this quad to haul stuff up and down my steep property. Thanks in advance.
      Hope you all have a great Thanksgiving!

      I have an 86 yfm250 (moto4 250) i picked up. 
       
      It bogs and pops a bit out the tailpipe if you can even get it higher up in the rpm. It is pretty gutless. I have other 250’s (timberwolves) and its ultra gutless compared to them. 
      It has an aftermarket carb on it that has a “W” on it  Its not a mikuni but it looks close  
      i figured jetting was off at the high end. 
      i had a mimuni that was very crusty, swapped the main jet into the W carb, and the needle, which was set on low slot 4 so left it there.  
       
      it actually ran much better, and cured what i thought was a problem caused by a lean condition from the W carbs main jet being too restricted when i compared to the factory mikuni  
      I had it out and was enjoying the upper rpms that i couldnt reach before without bog.  at wot it would fall on its face  low top speed.  
      after getting it hot, it would actually refuse to start after dying.
       
      back to the drawing board.
       
      when i first got it i adjusted the valves. So i retraced my work and thought maybe id overtightened. double checked, nope all good.  .005 exh , .003 intake, check.
      So i checked the compression. 
      here is the trickyness. help me understand this.  I am at 3500ft asl  in calgary canada  
       
      -  initiate test, it goes to 75psi right away. this is low. Even at my elevation im thinking 110psi minimum  
      but....this thing starts no problem. even -20c it starts. makes no sense to me. so i press the starter again and it goes to 85. Then i press it again and no change. Then i turn over again and it jumps to 95. Then again...no change. Then again and it goes to 115.  finally finishes at 120 and i cannot get it to go any higher than this. 
       
      ive repeated this multiple times. 
       
      i press and hold the starter...it will max at 75. Then a series of maybe 10 more quick turnovers from the starter and compression inches up to 120psi. 
       
      So, i think the low compression explains the low top end, and even the backfiring out the exhaust when hot. The exhaust is rich enough (incomplete combustion in chamber) and to ignite in the muffler. 
      it gets worse when hotter. 
       
      makes me think i have a crack, or something that is low down on the cylinder wall. When the piston stops just above it on the upstroke, and i then turn it over again, it adds pressure to my tester reading.

      Hey guys! Stoked to be here because ive found its pretty hard to get help for mini quads
      I recently bought a mini quad (it's a piece of poop so i have no clue the make) and it ran perfectly fine. I was running it a few weeks ago all day and it worked fine and the next day when i went to start it, the kickstart bar was super hard to push down but i could still do it, then it would skip and finish off hard to push down.
      I have fairly intermediate mechanic abilities so i was able to pull off the cover and start playing around. it seems the kickstart spring is fine but i noticed a bunch of metal shavings. long story short i posted pictures and took a video of how things are kind of running. i assume the gears started grinding and now they wont catch fully, hence the skipping?  
      Also, im aware the main gear on the left has broken teeth, i found out the hard way when i tried to take off the nut and the teeth broke.
