here is my thoughts , your bogging down could be a few different issue's , could be dirty carbs like mentioned already , wouldnt hurt to take them apart and clean them , it could be the fuel pump not working properly , or it could be the fuel check valve (fuel filter) is clogged up with stuff , if you follow your fuel line where it comes out of the top of the fuel tank you will see a little white coloured filter , just before the fuel line runs into the frame , you can pop that off and make sure it is clean on the inside . Another thing to check is under the seat, if you take the control unit and lift it straight up , the control unit is the large black ( think it is black) square thing , it has 3 plugs going to it , lift it up and under it you will see a little metal thing called a fuel tap , make sure the it is in the "ON' postion and not the "PRI" position . The "PRI" postion is only used if the carbs have been taken apart for cleaning and they need extra gas to get the bike running , as soon as the bike starts,you turn it back to the "On" postion .
now the bike creaping forward is just the idle adjustment screw , located right by the recoil starter( pull start) , you will see it is a little black plastic guy right by the handle of the pull start , all you need to do to that is probably back it out abit till the bike doesnt creap forward on you , it doesnt take much to adjust it .adjusting this may also help with the grinding you are experiencing , but also a few people have asked that question about their bikes grinding when they put it into gear , I have had it happen at times also , dont put it into gear slowly, jam it into gear , not while your moving though or the wheels are spinning in mud,make sure your are stopped and wheels have stopped spinning .
As for the smell of rubber , you shouldnt smell rubber , this is bad lol . Take the cvt cover off ( black cover on the right right side of the bike if sitting on it , right by your foot) and inspect the belt , if it is missing cogs replace it , if you can see strings and stuff dangling from the edges of the belt.....replace it, check to see if maybe it is to tight , check the primary and secondary clutches to see if they are glazed ( black stuff on them from the belt).
You have snorkels on the bike , maybe the carbs need to jetted ( I have no idea or clue about that stuff , it is more than I know right now lol) but im sure someone on here can help .
But before you go and rip everything apart , start with the fuel problem and go from there , you cant fix everything all at once , dont rip into the fuel system and then jump into the belt and clutching before the fuel system is fixed , start with one problem and after that is fixed , move on to the next and take your time , take pics if you need to so you remember how everything goes back together ,there are also alot of sites like Parts Shark and Parts Nation that have schmatics on line to help with assembly and disassembly .
