When on a ride yesterday with a number of friends and I have a question. First of all my friend owns an 04 R1 with PCIII and I don't now of anything else but the bike appears stock, he ways 200lbs with gear. I have an 01 Busa with HMF High Mount, PCII, BMC Race Air Filter and an ATRE. I weigh 250 in gear, bottom line is we did a role on from 2nd gear, 4th gear is when he went around me and gained 5 bike lengths. I started to walk him down when we hit 173 (GPS) but ran out of road. The only thing that I noticed on my bike was that my choke was on. Is this normal for an R1 to pull like that and will the choke being on make a diff on how my bike will get to speed and top end. Thanks for any and alll feed back.
