rcr mid pipe

does anyone think i should change anything to get abit more? what do you think rick?

 

well i geuss i am okay then ?

 

Personally I think you need to move up to a bit higher top spring pressure. The black/orange only gives around 6500. I think you need to try a red/yellow and you'll see improvements.

 

Crap, I just noticed the mid pipe. See what rpm's it's supposed to turn by calling Rick. If it's on line with the spring then I would say put a little more weight to it or change to a split angle helix for the rear, something like a 42-38 or a 42-36, or even a 40-36.

 

thanx bubba i will try to call rick i posted at his site and no anwser i know he is busy i just hope he sees this post

 

hey buuba how high do you think i should rev? what would the red/yel bring it in at?

 

hey bubba damm u were right rick said it should spin 7000-7150 he said try the orange and see how it is and if not go with red/yel
well i will head to the dealer next week when my tires are in and get another spring. at least my spring collection is getting better lol
