NEED MORE TOP END!!!

This is my dyno curve from my old bike which had bigbore 2 into 2 system with freeflowing cans and FCR carbs on a standard engine, just like yours.

Chart doesnt show RPM unfortunately, but the big drop-off in each gear is where it hits the limiter, so you can see you should have a pretty linear power delivery in each gear, but best torque and power is up to 7.5k rpm like KW says.

Hi, i have spent the past two seasons racing a TRX in UK Thuderbikes (have a look at TRX Eligible For BEMSEE Thunderbikes in the Bike Racing section on this forum). A couple of quick fixes would be gearing, i used 15-42 at Cadwell and the extra breather mod made it rev up to the limiter quicker. P.S. you should be racing it in Thunderbikes where it will be more competitive
