Attn: Minidragbike, cutting off billet rod dipper

I want to eventually install a billet rod in the 420cc motor and retain the balance shaft. I do NOT want to clearance the balance shaft I think this is stupid. I read where you had cut the dipper shorter or cut it off altogether on the ARC rods in the past, what "profile" do you use in place of the dipper?
Countersink the remaining hole?
 
Sometimes nothing at all
Oil still protects no matter what. At first I use to worry until I see. A video of what happens to oil at 5000 RPM.

In your case i would grind on the balance shafts a little.
 
I've had good luck using a combo of a center drill, 90* countersink, and 60* countersink to produce a "3-angle" oil hole in the stock rods that seems to help flow.
I'm on the track 10-15 minutes at a time so constant lubrication is vital. I can keep almost 1-1/2 quarts in the 420cc on a 15* mount:)
 
If you want more oiling you can do this and works well.

Use another fuel pump tap a hole in the block on top right above the rod crank jurn.
this will be your oil in.then tap another hole next to the oil drain or you can use the
oil drain and this will become your oil into pump.some engines have a extra oil drain
on the flywheel side and you can tap into that.as for the pulse use a Y fitting from
were your pulsing now or add another pulse line.works very very well and you
always will have oil on the rod were you need it.

POOR BOYS OIL PUMP.

Aren't the dipper on the opposite side, in other words pointing down, or do you drill another hole in the rod?
 
No drilling on rod at all you just tap a hole in the top of the block
above the crank and rod jurn.make sure its in the center.

I have seen a rod or two with an extra hole drilled that came from a "big time" builder. Ive never done it myself. Seen a lot of different innovative ways many have used to "improve' oiling. On stock rods of course. ARC forced oil dipper seems to be the best thing Ive seen so far. Nice work.
 
I use the arc forced oil billet rod vey nice.only had one break off the dipper end don't know why to this day
I called them and they sent me another one and I sent the broken one back.I only found it after I went
to do a refresh.never had one do it again.
