You'd basically have the run the 3/8" hose to the fuel side of the petcock using a barb connector/hose connector--whatever you want to call it--just run a long length straight to the carb from the fuel side (I wouldn't recommend this, since you'll waste a lot of fuel disconnecting it, unless you drain it into something clean and then put it back into your tank--which is just messy IMHO).
Here are some aftermarket oil filters you can get at your local auto parts store--you can use a Honda OEM filter if you want, but most of these cost less.
•Purolator Pure One PL14610, about $6.
•Mobil 1 M1-110, about $10.
•Bosch 3323, about $6.
I'd make sure to use silicate-free coolant (Honda HP pre-mix is good stuff), and consider switching over to synthetic bike oil if you're mileage is up there (over initial break-in period).
