The Secret F2 mod
Oh noooo!!! Not another story from the days of when we didn't have air pumps and had to stuff our tires with leaves.......
At Daytona, in the cbr600f2 days, we had a racer who was using our H09 carb kit.
He was talking to a well known Honda mechanic (first name initial: M).
M wanted him to use the HRC carb kit, but he wanted the rider to talk to
somebody and get the drill bit for the "secret HRC" F2 carb mod.
The rider asked me if I knew what he was talking about.
I said that I didn't know what the HRC secret was as I'd never seen an HRC
kit, but the normal, retail, Factory Pro 1.1-TI kit did a main air jet mod and the FP
kit had the drill bit supplied in the Factory Pro kit that I had already sold him.
The maj mod was good for 2-3 True hp at high rpm on an EC997 dyno, with no
losses at low or midrange
I asked my customer to show "M" the drill bit that came in the FP kit. He did, and "M" said "that's right" and asked where he got it. The rider told him that it's a normal part of the Factory Pro.
"Really?" said M
Both HRC and Factory Pro independently ended up doing the same maj mod.
The dynojet people with their dynojet dyno........didn't. In fact, they went
backwards and made the maj smaller.
I'd rather be like HRC.....
