.....going into my second year with a procom cdi....I've been running map #5 and it's been performing flawlessly....at $270, it seems that they've gotten a bit more expensive since I bought mine...I know nothing of gel batteries for the Triumph, but I can tell you that the procom cdi likes full voltage.....when I installed the new cdi, I also had to replace the 6 year old battery....as is my habit, I just drove down to my local Interstate Battery distributor.
