I just rebuilt the top end on my 2001 cr 125 i also put new boyeson 2 stage pro series reeds on it. When the bike is at idle i can hear a small ticking noise. i turned the engine over slowly and did not hear any thing abnormal.could this just be the spark plug firing? i have ridden around at about 1/4 throttle and let it cool down competely 2 or 3 times and there was no loss of compression and niether did the noise get any lowder.so i was just wondering is this noise normal? If not what could it be?
