I put a Safari 4.5gal (19L) tank on my ’09 DRZ400S last year. It has been on for about 4.5K miles. This spring while doing some maintenance I noticed some interference wear between the right top of the engine and the tank and also between the DRZ frame and the rear of the tank. See the photos below. The black marks on the tank are the wear marks. I am most concerned about the interference between the tank and the engine. My DRZ and the Safari tank have all the stock foam and rubber blocks installed. I have contacted JustGasTanks.com (the retailer/distributor) and they have contacted the manufacturer. I don’t have a solution from either one of them yet, but it is too early to complain about that. Either with their help or on my own I will raise the tank about 0.5” and support the rear of the tank differently. Has anyone seen this problem? If so, what was your solution?
