A Blaster can be made faster, but you'll have to spend a little money.
On my Son's Blaster, we started with a pipe, K&N filter, and rejetted the carb. Simultaneously, we ported the cylinder, and shaved the head. This made a considerable improvement in power.
While we had the engine apart, we converted to pre-mix, and eliminated all the oil injection system. This does not make more power, but rather ensures that oil gets to the motor.
Just recently, we pulled the cylinder and did a little more porting, and shaved the head, and recut the combustion chamber to increase the compression a little more, plus bump up the power even further.
VForce reeds were installed, plus a carb is on order, which I hope will arrive this week.
With the current setup, and stock carb, in loose sand, the Blaster is equal with a friends stock 400EX when they are ran without paddles (Holeshots and Ohtsu radials). On terrain where traction is better, I would expect my Son's Blaster to be slightly faster. I am hoping the 35PWK carb will really help with the top end and improve things even further.
