What to do while the carbs are off?

Hi folks,

I've got my 1995 VFR750 in "maintenance mode" right now. The carbs are off and away to be serviced (possible float valve leak), and will be synched after I get them back and reinstalled. In the meantime, I'm looking for suggestions of things to take care of while the carbs are off, since it's a small PITA getting them off in the first place. I'm going to do a general "cleaning" as the bike has years' worth of grime built up in all the less accessible places, but that seems like a no-brainer. Anything else I should tackle, while other bits are accessible?

[EDIT] The list so far:
* General de-griming of the harder to reach places
* Replace the air filter/Clean the K&N (doesn't require carbs off, but the tank is off)
* Check valve clearances
* Regap/replace spark plugs
* Change the thermostat (and old rad cap)
* Change the O-rings in the coolant tube assembly
* Clean out the galleries from the bottom of the coolant tube pits to make sure no sediment in there
* Use a flashlight to check for any excessive carbon deposits on the back of valves
* Be sure the mounting boots are positioned correctly
* Carbs don't need to be off for checking valve clearances, but it does make things easier
* Replace old fuel lines on the carbs and leading into and out of the fuel pump/filter

 

Possibly check the valve clearance, depending on your mileage. I've never done it so done it so don't know if the carbs have to come off for that. Maybe a set of plugs and new air filter while the tank is off.

 

Right, time to clean the K&N, for sure. Valve clearances, spark plugs... good suggestions. Thanks, Bryan.

All the major stuff seems to be mentioned already. But as long as you're asking... I'm a little OCD about old fuel lines on 20 yr old bikes. I'd swap out all the fuel lines on the carbs and leading into and out of the fuel pump/filter. And if you're doing the thermostat, the extra $15 on a new rads cap would be the last bit of additional insurance.
