Subject: [2cylinderhondas] Oiling and cooler (was Bonneville Honda)
Unfortunately I'm one of those people that can't remember the different AN fitting sizes, so I'll have to take a closer look at the system to see what size hoses I'm using.
Bill's adapter removes the stock paper filter element. It has an "out" and an "in" fitting.
From the "out" fitting we run a line to an very large external oil filter (the same filter a Ford 302 would run) - and we've got an aftermarket larger capacity (and more efficient) oil filter. A little ways after the filter we have a T fitting. Off of it comes a smaller line that feeds the head, and one that is the same size as the "out" line that goes to the "in" section on Bill's adapter. (When we run a cooler, the cooler goes between the "out" and the oil filter, so that the oil going into the head has been cooled also.) The smaller line for the head travels maybe 2 or 3 feet to another "T" fitting where we break off two equal size lines to the top of the head. (Remember - we don't have oil flowing up the cylinders to feed the cam/top end and one main bearing via gravity.) You can see the lines to the top of the head here:
http://images.garagecity.com/49/97/f1_i ... n.orig.jpg The photo is a little confusing - there are two lines with brass fittings that are the fuel injectors. The two fittings with the blue 90 degree fittings are where the oil get dumped into the top end.
Besides the benefit of cooling the oil, you also add a quart to a quart and a half more capacity, which I think is a plus.
I think next time we'll put some rare-earth magnets inside the oil filter and maybe even epoxied inside the case.

(My goal would be to come up with something so I can get my 750cc motor, and everyone else can get a new crank/piston setup that gets them a little more displacement and power along with the comfort of knowing it's new and should last a long time . . . )

If anyone out there plans on running a vehicle, I highly advise attending once to spectate. Get a feel for the process, environment, rules, etc..
