please help next step is the junk yard... Not playing
 

OK I've cleaned the carbs 100% they look brand new inside and out, I cleaned the k&n air filter, changed the plugs, changed the oil, and had the carbs synched! I don't know wtf is wrong with this bike it runs amazing 1-4 gear but as soon as you shift into 5th gear it bogs down and won't go over 7k rpm same thing in 6th. Could the voltage regulator be the issue? Oh I also replaced the gas tank filter. And the inline filter has been removed all together. What could be causing the bike to bog down like that? I also plugged one of the breather holes thinking it was getting to much air but that did nothing at all... Please help even if you don't know what it is through a suggestion on here I'll try anything! Thanks all

Hey Nick,
Is this the same bike from your other post?

Last you wrote it was good through 5th gear, is it now only good through 4th ?
You may want to just continue in the original post so that readers can get the entire story of what the symptoms are.

do you have the heat in place?
