Just called my local bike shop (not triumph dealer)looking for jets. He had mains in stock but asked why the hell I wanted to change my pilots I said because it only got 40's in it he said they not really change anything.Now I might not be the smartest tool in the shed but it seems to my you folks have extensive knowledge on these machines and I wonder why the shop owner would say something foolish like that. I said that it will help with the lean running at low idle.Hope that was right Thanks Todd
