I just finished putting my bike together and went to turn the motor over using the kick starter. The bike turns over for about a kick and a half but when the intake cam lobes get to the the intake valve buckets the kick starter stops and is very hard to move. The odd thing about it is that when I take a socket to the crank and turn the motor that way it is smooth all the way through the strokes. There is a little resistance where the intake lobes hit the intake buckets but not even close to the amount of resistance that the kick starter is experiencing. Could I be 180 degrees off on timing??? Any help would be greatly appreciated!
