these days, predictable.. all the paperwork says thats what they will do..
the salesman, and the parts guy, and the service writer can say anything they like - but its the paperwork.
race tune - end of engine warranty.. right in the paperwork.
what i always say - do what you want its your bike, but its crazy to think hd will warrant a modified bike
recently a guy down the street from me, not quite a block away was going to have a huge kit and tune etc etc done on his month old m8 while it was still in for winter storage, said the dealer said they would cover the warranty.. i told him to ask for that in writing - the next day he came back all butt hurt - the warranty would be void except at that particular dealer and they would do a dealer warranty only if they did all service and would not put any of it in writing. .. mmm yup thats the way it is now. he was by a few days ago - its still stone stock.
