Whats the reason we have a pipe going from the throttle body into the air box. What would happen if i just put a cone filter on there and put a filter on the engine breather pipe.

Go and speak to this bloke. he lives in Australia http://www.yamahar125.com/members/motobum.409/

Here's my dyno test sheet

Pick up is a bit boggy. And when am crawling in traffic it's quite jerky.

Just done a oil/filter/plug change and found my plug to be white. so the bikes running lean. Had it on dyno and it was running air/fuel 14. How can i sort this out? bike running stock apart from a scorpion full system. has the stock ecu been mess around with by pre-owner? And could i reset it. if not how to i sort this problem out. All comments welcome.

Not the air mod that goes into the exhuast. This one

What would happen if my mate cut's the pipe going into the trottle body and puts volcity stack on it.
