CBR250RR specs

[Homemade WRX]

well, I'm at a hang up on my design as our motors aren't here yet.
I really would appreciate some help.
I need:
-exhaust port diameter/area.
-Intake port spacing 1-3 and 3-4 (you know what I mean ).
-length from entrance of head to back of the valve for both intake and exhaust.

Just hung up on these points and need them to keep my Senior Project moving along.

Thanks,

I will pass these questions on to current UTA team members. I'm sure they can take the measurements for you.

thanks, I had dropped kevin a line hoping he could do the same but I don't think he has been on lately.
My CBR250 forums aren't too much help as most are confused with what I'm asking.

Yea, Kevin and myself aren't on the team this year so we don't get on much. I was in the shop tonight though and couldn't find any spare heads/motors. The current engine lead is aware of your post, hopefully he can take the measurements.

yeah, Kenny from the 98 & 99 team said he would try to help me get what specs I need too. Just hung up and the prof is breathing down my neck.

well, I appreciate the offers to help from the UTA Team and Alum's but got word today that customs has our crate of 3 engines waiting for us.

EDIT: I'm now happy as shit that we have 3 complete (ECU, Carbs, etc...) sitting in our engine room awaiting inspection
