Hey TTer's I know this subject has been beaten to death Howener I have done my homework and tried to search out this mod but couls not find anything specific I have tried to pm Yamaben as well and no response so he prob on vacation or something. I am looking for the decomp mod for my 99 400 in detail. like part #'s or a list of all the parts i need ie. cam, chain, plug... everything I would need. I love my bike but if i had to pick one thing I would change It would be how hard it is to kick over. Especially when it is hot and i ahve been ridin' and my tongue is hangin' out a half mile behind me So if any one has info please pm me or resopnd to this thread. Again i apologize for beating this dead horse and thanks in advance!!!
