hey bro
i was messing with my america this weekend thought the snorkel was the crankase tube which i've conected to a K&N filter when i found out the snorkel was under the seat i took it off
oh i also plugged up the tube that the crankcase breather tube was in
it was hard to get 170kph i took it out to the motorway (freeway to you yanks) and the d**n thing went up to 180kph with no probs
short pipes with baffles help keep the flow free i think
my next job on it is gonna be 18t engine sprocket 133 main jets 45 air mixture jets
hopefully it will stop popping on decelaration and have better fuel flow we shall see
maybe one day i will see 120kph (in my dreams)
