what big bore

[flaneledholes]

I am lookin into bb's for the 400(isnt cuttin it with my raptor and modded 400 my bud has).Will the 505 be a good bore for the woods???? I want the most power because all the racers in town do a little draggin at a 700ft drag just a little off trail. Please help I dont want all the guys laughing while I give excuses why I cant beat them.

I do not know about a 505 but my motor builder makes a 493 and it actually produces TOO MUCH POWER for the wood. yes there is a thing as too much power in the woods. he does build a 463 that i amazing for woods rideing. It has great smooth reliable powe all over.
