Hi to all. i have just been reading through this thread,, 10 outta 10 for some of you for your efforts! I have a k&n filter removed from an rvf and its in exellent condition, i was going to use on my nc30 road bike project but decided to stick with the original filter as i didnt know enough about jetting the carbs! the k&n filter fits just as well as the original filter.. i did plan on getting my nc30 set up in the future to suit k&n, still might do?
BUT if sombody is willing to make me a good offer,, it could be sold. haha, Moore
