I did the PAIR Mod last night on my 1300C. Followed instructions from Bare's page. ( for the 1800 ). A little different than for the 1300. Everything went well. It took me about 2 1/2 hours ( I also did a deep cleaning of the bike while it was torn down ). Took the bike out for a test run after. It started Great with much less choke needed. Virtually stopped all the decel popping. Next the SCAR and Hypercharger.
