i just took a bunch of the tuning disks out of my muffler and it made a huge difference in the torque. i can now wheelie first and 2nd gear without dropping the clutch or hardly leaning back. i ran it without the spark arrestor for a bit too, but the noise was too much to bare lol

 

hey man how many disc were u running and how many did u remove

 

yes i know. it makes a big diff. i wanted to find a Snuff-R-not end cap. liek they have for the e-series.. seen one before in a magazine.. but cant find it now... but i love the soudn w/o the closed cap.. i leave all discs in.. so who knows
