Posted August 22, 2020 (edited) My x11 was struggling around 6000rpm. I inspected the spark plugs. All good. Then I took a look in the fuel tank... Edited August 22, 2020 by hc_karpfen 0 Share this post Link to post
Posted August 22, 2020 The former Owner let a complete fuel tank dry out. The brown dirt is what remains if the whole fuel ist dried. What a mess! So I took some lemon acid and a sponge... The result is not bad. 1 Share this post Link to post
Posted August 22, 2020 Three rattle cans of brake cleaner later, the fuel pump is fine again. The next 2-3 times i will put Aral 102 Octane in and a bottle fuel system cleaner. 0 Share this post Link to post
