Does anyone have a 580 kit or any type of bug bore kit for the pred? How reliable are they?

I know that Doug Nicholas is running them, on all of his stage 2 kits and higher.....he runs a 558cc big bore kit though(I think)....call him to find out more, or check out his site below.

 

HPD had some issues with their old version 558kit, now they have a reworked kit thats supposed to be bug free..HPD

 

I have the 580 kit it works awesome. I just went to far, shave the head, bigger valves etc. Now it eats starter components(too much compression). So I installed a frost plug in the stater mount hole. removed all starter parts and pull start it with my other bike . Now I'm going to make it into a full drag bike and buy a second one to drive in the trails.
