New 2012 motor build

[Ex_Rider43]

Time has come to make plans for my MX race bike motor. Bike is an 08.

Here is what I currently have

Dasa Race head
OEM valves with race cuts
943 Webcam
lighter buckets
Wiseco 13.5 race piston
Hotrod rod on OEM welded crankshaft
Dasa race carb
FCI intake 06+ intake
RC5 exhaust by Factory 43 ( make them myself )
MXP transmission and Full Hinson clutch setup.

I can pull holeshots a few times during the season , but I would like to have a little more power for the 2012 season as things will be more serious. It is a 52 hp / 34tq build on a dynojet Dyno.

Im thinking about a new cam , maybe bigger valves ?

Whats your opinions and what kind of gain i can expect with that?

I would get rid of that dasa head and get something quality by somebody else. I have never seen a fast dasa motor besides the ones dan does by hand or expoxied. Go with +1 valves ( use the crf ones ) and you will notice a big difference.
