NO!!! Its rules out nothing. You can't tell anything from what you had him do!!! It was a waste of time. YOU CAN'T TELL ANYTHING FROM THAT TEST!!! THAT TEST TELLS YOU NOTHING ABOUT LOW END!!! IT IS A POINTLESS TEST!!!!!!!

Having Him Ride The Bike Around A Little Didnt Help Much I Admit, But When We Get Him To Full Throttle The Bike, Then Kill It, We Will Know!!!!!!!!!!!!!!!!!!!!!!

He is not having trouble with full throttle!!! This is an issue that occurs at idle and general riding. What would knowing the fuel mixture at full throttle tell us??? The main jet is not our concern but will show up after 1/2 throttle... Why are we testing things that do not affect anything???

does your bike have a decompresion lever this will help your bike to start eaisier rather than putting alll that force on the kickstart

I didnt read through the whole thread but hows your valve clearance? this would cause this kinda deal.

i really couldnt tell you my manual doesnt help too much but ill have a look tomro morngin what tools do i need to measure the valves?

Danny, Honda bikes have them built in. No need to pull one. WR brings up another great point. Please check valve clearance. I assume you know the specs since you have the manual.

the only thing you might not have assuming you have a metric tool set, wrenches, ratchets and sockets, is feeler gauges.
