Did the Barbarian Jumper Mod on my ‘05. Increased each cylinder’s number by 5. Now the perceived stumble I felt every time I took off from a stop is gone.
Spooned on a Bridgestone T31 on the front. Checking the balance, showed I didn’t need to add any weights. Yesterday spooned on a T31 on the rear, added one weight.
Bought an ‘05 with 87k miles, was real buzzy at 4 grand. Checked clearances at 91k miles and found 4 valves out of spec, 1 intake and 3 exhaust. No more buzz.
