i have been reading about hot cam & big comp bigbore kits all together. the hot cam from what i see eliminates the decompression kit. and the 10.5:1 pistion kits with the cam make it hard to start when hot even for the electric start with good fresh battery. so i was thinking what if you milled down the dome of the pistion to drop it a few points like 9.5:1 compression . would this help and or do thay make a pistion like this. added: or get a custom pistion made as some offer to do for about the same money.
