Vesrah GG-3021 is a 33mm valve for the 250. It measures 33x5.5x88.57. The stock valve is 32x5.5x88.66mm.
I have to go look at that cam.....</end quote></div>

The stock 230 cam in the middle, megacycle stage 1 top, drz stage 2 on bottom.
Using ported airflow numbers from http://members.tripod.com/cb75...ing_the_Honda_Head.htm
basically, the same 3 engines with different cams.

now the engine i am using is 190cc, it's 70mm bore by 49mm stroke. i have seen dynos as high as 22hp out of the engine i have.</end quote></div>
Your engine can rev higher, having only 49mm stroke, therefore may have higher peak HP numbers.... But I don't think it will have more under-the-curve area than the 230. The 260 kit for the 230 is a 70mm on a 67mm stock crank.... 9mm more leverage on the crank with the same size piston.
