Haven't really been down this road, but exploring some options for higher HP for a client. Any thoughts on something along the lines of ....a Thumper Racing 520 kit on a 450SX-F. Vs a Raze ECU, exhaust and de-smog on a 500 EXC? Both would be new bikes....I am assuming the SX should have a performance advantage, but no idea how much. The 500 would have the advantage of maintaining the "factory seal" on the motor.
Not looking to get hung up on the transmission....but more on if people have ridden either, and if they were satisfied/unsatisfied with the upgrade. Or if there is another option worth looking at....FI is out of the budget.
