yfz 468

[timbomoose]

Here's a chart from an 04 yfz450 with stock intake,stock carb,rev box,stock cams, birtbike crank,ported head,trinity exhaust, and cp 97mm piston compression 12.2-1. Next will be redynoing with aftermarket intake and programable timing box and possibly cams. Lowend and torque on this thing is phenominal and holeshot king. Notice though how it falls off on the top end. Pulls good to the stock rev loimiter but with this rev box is missing the boat.Will be changing the rev limiter when it goes back with a few bolt on parts. Higher rpms do not alway mean more power.Blue line 468yfz. Red line stock cannondale with full pipe and cannonboomer intake from same dyno.

the next time down to the dyno it will have a dynatek fs programmable ignition, a fci intake, re-ground intake cam, and 13.0-1 compression. the magic number is 55 should be very close hoping to get it.
