Hey All-

I am gonna build up my Rap a bit. I'm thinking head work, high compression piston, and new cam. What do you suggest? I could do everything except the head work. Have no one local to do it. Any builders you would suggest I send it to? I do a lot of different types of riding. Looking for more mid, and a lot more top end. The bottom end is fine the way it is now. I want more of the excelleration rush, and with the current setup, it really drops off at about 6500 rpm. I'm pretty bored, and need more power.

Thanks in advance for the help...

 

I thought most the power gains are from the head work done? I woudn't want to mess with the head. As far as Trinity goes, I think that they've made some false horsepower claims. No one is going to get 63 rwhp from the basic kit, but that's how it's advertised. No matter how you try to explain how they arrived at those numbers, to look at the advertising, it's obvious they are using methods that aren't all that honest to gain customers. What about Sparks? Anyone had any head work done by them?

 

As you said, Sparks is my favorite out of all the 4 stroke techs. Head over to their website and read up on em. They won FSW last year, and is a big contender this year!

Thanks, I'll check them out. I know at one time there had been a lot of complaints on here about them, but recent posts seem to be pretty positive. Also, wasn't there some special go-go juice used in the sparks rap that won fsw last year?

Anyway, thanks for the info....
