i posted on the general tech and didnt get many replies so i thought id give it a try here. My bike is bogging down when i hit 8,000rpm and droping down to 4 or 5k as if im letting of the throtle, but i have the throtle fully open. any help would be apriciated since i dont even know were to start looking to fix the problem
thanks

 

have you pulled your filter or breather box off lately? if you don't get the ram air back on right the ram air will not work right. also if the filter is getting clogged this can happen.

 

thanks for the info im gona give that a try

 

When was the last time you checked your plugs?. Check to see if they are all ok. You might have a fowled plug.

 

Fuel filter, fuel pump diaphram? EM600 I hope it only the air filter, please post when you get it sorted out. thanks.
