Here is my mods : Evoluzione AIr filter + O²modifier + Two Brother dula exhaust + Juice box :
When my Spyder is under 4000 rmp the throttle response is not so good, the engine cut off when the throttle is full.
After readings posts, I did the canisterectomy and install the crankcase.
Final result is the same : above 4000 rpm the Spyder is like a very old lady, engine cut off, bacfires, etc :gaah:
4000 rpm : I can hear a sound like "bzziiii" when the throttle is full on the left side of the machine, and the powerhorses are back again.
My question is : is the JB comptatible with the O² modifier or should install back the BRP one ?
Thanks for help, cause in 3 weeks I'll ride to Austria for our first European SPyder fest ...
