I just did the HRC card wiresplice and the bikes starts. I want to properly jet the bike for a drilled airbox and aftermarket exhaust with the HRC card. I ordered the HRC jet kit and the jet numbers are nothing like the numbers on the stock/installed jets. The jets in the bike now are 55's maybe 155's hard to tell. The jets recommended by someone on this forum awhile back were 192's. The jets in the kit are numbered 1920 (99101-3931920). The other jets in the kit are likewise numbered. Do I just drop the last digit and a 1920 is a 192? Does anyone have any advice for a conservative baseline setting for a bike run in So. Cal. around sea level setup as described above. I also want to use the HRC "B" needles. What is the best way to change these. I got the air solenoid Y fitting but not the X fitting. Has anyone run the HRC kit and if so do I need to change the solenoid jets if I use the Y fitting or should I leave it alone as I don't have the HRC X fitting. Any other advice will be greatly appreciated. I know it's impossible to say exactly what jets I need but a similar MC28 should be close. Thanks,

Steve
