also note that if you decide to replace the wires (again, I personally suggest the generic automotive wire kits from Accell, the yellow silicone TINNED STRANDEDED COPPER WIRE CORE with 7mm diameter insulation) that when doing the coil end, you need to retain the ferrule and the threaded "wire nut" from the oem assembly. Simply slide the nut and the ferrule back onto the new wire before inserting it into the coil, note that the coil only has a sharp "needle" in that end, and requires you to shove the squarely cut wire end into the coil far enough to bottom it out, and cause the pin to be fully inserted up thru the core of the wire before screwing the nut and ferrule into position, this crimps and holds that end assembled.
I want to add another suggestion, especially if the fuel tank has not been off this bike in a long time, bear me out on this please...
if this tank has been pulled off twice, and stirred up, it is likely that any water that has accumulated in the tank over time, due to normal circumstance, will be now mixed with the fuel. I suggest highly that you pick up a bottle of Heet or IsoHeet from the autoparts store a.s.a.p., and dump it into the tank, and ride a while. This will bind up any moisture with the fuel, and allow it to be burned up instead of clogging up the low speed circuits of the carbs...take it from me, this occurs very frequently when people remove and replace the tank.
