KX250f Cam Timing

I have torn my kx250f down to the cases, putting in a new crank assembly, really getting it ready for some epic trail rides this summer! anyway, while i have the motor down, i am trying to make any cheap improvements i can make. i have the 07 clutch springs, 07 intake boot, my friends dad who has built motors for years is doing some clean up work on the head (nothing major...i use this bike as a trail bike) and i was wondering something on the cams. Because of my budget, i am keeping the stock cams, but i was wondering if you guys have seen power gains by advancing or retarding the timing a bit on the cams. I know the honda's have been making just as much power by changing the cam timing a few degrees as you would if you put hotcams or web cams in. i also know that team suzuki flattrack is doing the same thing with their rmz motors. i was just going to see what you guys have experienced if you guys have tried it. thanks so much for all the help!!

well, i know you can most of the time get more power in an area by doing this, but i was wanting to see if anybody had already experimented with it and how far they went. man you should make the trek out east to ride that trumpet on some limestone tracks here...that has got to be a sweet ride!

well i looked at timing the cam a bit differently like putting a pipe on it...just personalizing the power. i was wanting to get a little more out of the bike on top, it seems flat to me, but this is just my play bike, so i think i will just time it to stock specs. i really hate to dump the money for cams into it when all i do is ride a little motocross and cover a ton of ground on the trials with my friends on it. thanks for the input! keep it sideways!
