my 97 kx100 wont kickstart from cold without the help of starter fluid. the carb is tuned and good, actualy its a new carb. but after i get it going with the fluid and it warms up a bit, it will start first kick all day. as long as the engine stays warm. it still pulls the front wheel up no problem in first and second gear. the reason i dont know if it needs a top end is that i dont have a compression gauge so i cant tell exactly. the only way i think i can tell is that when the egine is warm the piston expands, causing it to have more compression and suck gas better than when cold. help!
