when you consider my blaster which is bored .40 over with a 4 degree timig advance mod, Boyeson pro series dual stage reeds, custom exhaust,
absolutely smokes by buddys' ltz400 the 240 big bore kit should absolutely smoke that 450.
my sons stock blaster keeps up with the ltz400.
no joke guys!!! the blaster makes the ltz400 look silly.
my friend recently added a sunstar 42 tooth rear sprocket and can keep up with me now.
but not bad for a 200cc!!
especially when you consider that the blaster has a 6 speed tranny.
and the 240 big bore kit adds some serious power and speed.
