difference!!

Recently I have been drilling into thick metal (1/4" steel, 3/8" steel, 1"aluminum) using regular bits that I had found in a toolbox in my basement, and I recently bought a 5/16 carbide metal drilling bit. HOLY COW!!! This thing will go through 3/8" STEEL in 30 seconds! I didn't even realize how...

I read supernovas trick and was about to try it with the piggy back spring idea but I didn't have any spring around and would have had to drive into town. I have two db30's with the 6.5 harbour freight motors. I bought promod's jackshaft when the bikes had the old 2.8 motors on them a year ago...

Juts swapped out my stock HF plug with a used ngk from my saturn sl2....what a difference so much more responsive throttle wise sounds better sounds healthier so awesome.:thumbsup:
