Hi everybody, first forum I have joined. I've been a biker for 40 years ( I started very early ) lots of different bikes over the years. Fortunate to get a HP4 Carbon in the summer and looking to upgrade a few things. I went to BMW Barnstormer in Maidenhead last Saturday and had a very close look at the new HP4, totally smitten. Anyway, has anybody on here had experience with fitting an IRC downshift blipper and can anybody advise me on how to adjust the rear sets as its really not obvious. Look forward to your comments.
