Sure Matt - and I couldn't even convince you to ride my 1000SS when we were at Mid-Ohio... Maybe you can to post up the before/after chart from the DP cam instalation on my superbike here.

I look forward to having you drop in the 2mm over valves and TB work on my bike this winter. Maybe I will let you take it for a ride then.

I'd love to see you build a 1000SS for the shop - it would be great to be able to race in something other than just Thunderbike. Maybe I have a slight chance to keep up if you are on a LW bike rather than the 748R.

You know I am scared of your bike but I guess I will have to suck it up and ride it because it is an amazing machine. I am not afraid of the engine; just an overall paranoia of the time and money you have in it. It was awesome to see it in action at Mid-Ohio and earlier in the year at Blackhawk.

Foster gave me the go ahead to rebuild the old Moto-ST DS1000SS last week and there is also another engine on the way. The deal is if I do the labor he will let me race it next season. I have no excuses now.

I'll get the dyno graphs up soon.

OK, here is the dyno graph of my 1000DS motor before and after the installation of DP cams. Inititial build includes 1080 Pistal pistons, lightened and polished crank, lightened 749 gears, Carrillo rods, mildly ported heads and TPO-R pod filters. It is worth noting that we are running very mild compression - in fact it runs just fine on pump gas and we never had any detonation or issues. We picked up lmost 10 bhp and 3.5 lbs/ft of torque by going to the DP cams with some careful tuning by Matt.

The bike is already amazingly fast for a LW bike. More work to come this winter and we expect to gain even more power as we go. It would be very easy to just increase compression to pick up easy power and torque; but we want to keep the compression low to take it easy on the internals so we are going to do some work on the heads to see where we can go before we start increasing compession and going to race fuel.
