Try torquing to 17 ft-lbs with a new plug and see if it stops the leak. If not, a spotface machining on the seat is needed.

Hey guys... has anyone run the stick needle on the 2nd clip to lean it out one notch on a stock set up?
I have all stock except the oiled air filter and i run a 25.7 pilot (stock was 50) and a 140 main. I run the air screw at 1/4 out otherwise it bucks like mad when i close the throttle. I think my current setup causes the 1/8 to 1/4 throttle to be too rich and i get that burbly spot between 4 and 5000 rpm on the hwy and bombing around town.
Is leaning the needle something one can do to clean up that area of the rpm at steady throttle?

hey chuck its been a long time, does this installation cover the daytona also?
