If you ever see coolant or oil on the ground you might have a leaking water pump seal.
First check for cross contamination into the oil.
The oil will look alot like chocolate if antifreeze has been getting into the crankcase.
If so then dont run it, antifreeze will destroy the main bearings fast.
If you've just purchased the bike, I suggest to go thru the entire front end of the engine when replacing the water pump to get it over with and it's alot easier done now after removing everything.
Replace Hoses,
replace timing belts (very important)
thermostat (test opening and closing temps)
And of course water pump and seals
Anything else you see questionable
When doing the water pump, plan to pull the radiator all the way off.
This makes changing the timing belts and water pump ALOT easier.
Oh, on a fully dressed 1100 you'll need to remove the horns and bend the mounting tabs up to get the top of the radiator off the studs and out.
Most important when installing the pump in the front cover is to make certain the recess the pump slides into is absolutely clean and burr free.
First dry fit the pump without the Orings on to make sure it will go all the way into place.
When installing the pump, smear a thin coat of Vaselline on the Orings to aid them sliding in. The objective hear is to take good care of the Orings because a tiny nick in them will result in oil or coolant leaking from the weep hole or cross contamination.
There is a coolant passage which runs thru the engine at the front cover up to the thermostat housing. Make sure that passage is clear and not corroded, it's a rather small passage but very important. It allows circulation of coolant inside the engine before the thermostat opens!
Under the front cover there are 2 sleeves with Orings on them, they fall out sometimes so take care not to loose them.
A manual is a must. The Honda shop manual can be downloaded from Here
I like to take pictures.
Have fun with it, if you need any help along the way just ask.
