Hi, everybody! Did any of you ever install a K+N air filter into the GT? I got annoyed about the mess when washing out the air filter sponge. I then read that there is now also a Lufi from K+N for the GT. K+N advertises with it, that the Lufi can be installed without further changes of the gas factory. So I got a filter then. 40 Euro is not really a bargain but such a K+N air filter looks good too! ) Just before the big tour I also made my way to the south. Old Lufi out K+N Lufi and see that the lid can no longer be turned. The K+N filter is almost 10 mm higher. So the lower holder is modified so that it fits. Done! During the test drive the Gt did not pull right anymore. It seems to run permanently lean. Only from speeds above 4000 it goes better. Nevertheless, the mixture remains too thin . . . . So first of all the old filter again. Last week on the Intermot I have dan n times the K+N representative referred to my problem. His narrow cometar: Normally you don’t have to change anything about the carburetors. But it happens that the engine doesn’t run optimally when using our filters anymore. Here I would have to talk to the specialist workshop and have the carburetor re-adjusted. On my objection the K+N advertises that you don’t have to re-adjust it at all. But I can do my problem again at the headquarters in Ho lland mail. Maybe they know something. . . . Maybe someone has already gained experience with the K+N filter. Or someone can tell me at which place on the carburetor I have to rotate best and which nozzles I have to change. Would be a huge help. Until then! Thanks + Griessles Oscar
