Best jet kit??

I had the Holeshot Performance kit and timing advancer in my 05 FZ1. No drilling in the carbs,, and it absolutely came alive! Easy to do, simple instructions, works great. Maybe it was a tiny bit less hp than an Ivan's kit, but much simpler, and the difference was huge. much more responsive AND better fuel mileage, since the fuel / air ratio was finally set right.
 
A lot of riders I knew loved their Ivan's kits. I was a bit nervous about drilling on the carbs. No drilling with the Holeshot.
If you're paranoid about drilling, I would say Holeshot. If not, Ivan's is great.
 
Looks like I'd go with the Holeshot kit.. Just a little nervous about the timing advance part of it.. But you should know I've only got a (ART) slip=on...
