Don't apologise for your English, it sure beats our er Russian or whatever hehe!!! You sure need to read and study all of the information on here. You have the classic XT660 symptoms and you can sort them out no problem but you must go step by step. In other words, write down your starting point. Then change ONE setting and try the bike again and write everything down. OK???? Ciao Simon
