I've got my motor all torn down, and will be ready to re assemble in a week or 3. It was a Sputhe 104, but now will be 106". I have Branch heads at 80cc, and a stroke of 4.625 with a bore of 3.812. Jims roller rockers, mikuni 45, Rinehart exhaust. (I had to replace the crank pin and rods)
I have been running a Crane hi-roller cam, 1-1005 H304-2 grind, and at .600 lift it seems as there is room for more power. I estimated the cr at about 11:1. Still have HD lifters, with 30k miles on them, and they check out fine, but will put new in if I change the cam. The bike is a 1995 RK, and has a Dyna 2000i ignition.
What would you recommend for a cam change, and still keep it a daily driver.
I have considered a Wood W9B, but have no experience with that brand, or know of anyone using it.
Thanks
Steve

 

Hi Steve, sounds to me as if you are working close to the limits of what can be done with an Evo. It would be worth contacting a shop for advice IMHO, such as one of the HDF sponsors, like Hillside Cycle.

 

I will do that.
Thanks.

Hillside specializes in Woods products, your going to have to jump to a 9 series to let some air out the cylinders and the W9B sounds like a direction, the W6H has too early on intake closing for that compression and will be a ping monster. Redshift makes a cam in the 630 range that is popular in the big horsepower Evo world.

I use a Woods cam and runs as advertised but be prepared to set the lifter plungers deeper than normal, get everything set right and good to go but sometimes needs some patience to get right ot sounds like a mad sewing machine. My W6H is quieter than a ***** at a white wedding dress auction but did some trial and error to figure it out
