I have GRP .28 that for the life of me I can't get the bottom to tune.

I think it is the front bearing is the problem. It leaks when you do the blow test between the inner race and the crank.

I read they all leak with the blow test, but I never experinced it with my other motors just the GRP .28's one GRP Tuned and 1 Ninja .28 grp.

I was told by a modder that he thinks the cranks are just a fuzz small??? Anyone else have this experience?

PS I just put in a new bearing and it still leaks...Have not fired it up yet though..Kind of ticked about it at the moment...
