PerformanceBike 2nd installment- '08 ZX-10R

Just finished reading the latest issue of Performance Bike and the second article on improving the "limp wristed, pathetic" mid range. If you remember they picked up 3 HP across the low and mid range with a PC and some dyno time. Next they pulled the butterflies and went back to the dyno again. Improvement was up to 8 HP in the mid range. This time they had the owner of Kent cams reprofile some stock bumpsticks- a little less lift and duration, some slotted cam sprockets, and a third trip back to the dyno. Results? Gained 16 HP in the mid range at 7200 RPM, with NO loss of peak HP- still at 165HP. But peak power was moved down about 1000 RPM. But the bike didn't feel as crisp or snappy because it wasn't lean anymore and no longer had the big noticeable hit at 8000 RPM because of the fatter mid range. Still runnin' the stock exhaust too. And their long term CBR 1000 has joined the ranks of oil consuming CBR's. About 1 quart over 1,000 miles- no track days either.

Man, that CBR oil issue is big! Way to big to live with, I would want my money back, what a joke, i thought Hondas were supposed to be rock solid as far as reliablity goes, there are guys on the CBR forums claiming their bikes are loosing power along with the oil comsumption issue, they are definately tell tail signs the engine ain't gonna last.

its quite obvious how castrated the midrange is on a stock 10R. PCV + full system + Xtre is my solution!
