what are you alloud to do to the fuel injection? like porting polishing smaller butterfly flaps smaller rod things that turn them stuff like that? removal of components that arn't usefull? idk what is acualy possible to gain power with but what is legal?

The rules say that you must use the throttle bodies that came with the engine and that they may be modified for use with alcohol. So, in reality, as long as you are using the throttle bodies that came with the engine, you can modify them however you like. How can anyone argue what is modified for use with alcohol?
That's how I read the rules and that is what I have seen with many engines on the dyno. I haven't really seen many modifications that actually gain power though.
Anyone else have any thoughts on this?

so stuff like drilling holes in the throttle flaps is legal if that is my was of converting to alcohol? sounds good to me even though there not realy anything to do i know anything about these on what will acualy gain power. but how about duel injection can you run that on a 2005 kawi 636? and thanks alot for your info.
