0.004 / 0.006

check, the drums, no scratches, if good the surface of the drum, interchanges the drum, for example, move the drum cyan to the drum yellow.

i have both the hammer drill and impact driver and have been interchanging the batterys without any problems

hi this may help,check the voltage of the battery first,should be at least 13.2 v static,and on a completly different approach,check that the sidestand and clutch lockout switches are functioning properly,particularly the sidestand one,they are prone to failure and when they do they wont let start current through to the starter relay..hope this helps..cheers

Go to Sears or a hardware store and get a 2amp battery charger. Fill the battery cells with water to cover the top of the battery plates. Let charge overnight. The battery may take a charge and hold it OR it may take a charge and not hold it for more than a day or two. A new battery may be needed.

if you plan to modify your exhaust system you will have to rejet your carbs to compansate. kits are availableat most aftermarket shops.

Does it stop when you pull the clutch lever?

If so,it may be the throw out bearing.
