If you are dragging only slightly you can take out the shock and place a washer between the upper shock bracket (under your dick) and the frame. The washer needs to be at most 1/8 thick which will raise the bike 3/8 at the wheel. Simply drop the washer on the bolt that fastens beneath the tank and reinstall the shock. It will cost you less than a buck for a stainless washer at the hardware store.
This should get you by until you lose some weight fatty!
Could I put in one inch extenders without change all the cables?Fyi: you could have bought one at Harbor Freight and return it afterwards
A set of 3" or 4" would be even better
