well, i just joined the other day, first post on here so hi guys. My question is if anyone has tried the sparks X-4 cam. requires rockers and springs, says on the site it's extremely aggressive, just wondered if anyone has ridden one before, interested in how the perform.

What kind of riding do you do?

alittle of everything, i like dragging my buddies lt450r and another's yxf450 alot, some woods and wide open trails mostly. i would switch to an x-1 likely if anything if i would, i was just wondering how hard the x-4's came on.

I know the stage two cam is pretty rough but really helps your top end. The x-4 sounds like it is a race only cam that would make any other riding difficult. I may be wrong but that is my opinion.
