wont rev up it seems like its hunting for something HELP!!!

bike wont rev up
wont move or anythin ive tryed 3 carbs changed the stator not sure what it is

 

cheers mate its just ive fitted the kit and the crank but the bike starts but it doesnt revup its like its hunting for sumthing

 

I once got 2-stroke all over the end of the spark plug and it wouldn't rev much, stupid but you could clean it to be safe lol

 

is it hunting for deer? i find that they dont get many, if you get it to hunt for rabbit you might have better luck

 

who fitted your crank??? i had this problem with mine had to run with the bike and jump on to get it going only to find out i had warped/dented engine cases

 

found the problem it was the engine to frame earth

 

i think i may be having this problem at the moment it starts and ticks over but wont go anywhere when i increase the revs. what did you do ???
