Crankshaft Truing Procedure Honda ST90 CR KX YZ RM CRF YZF Crank
This video shows how to check the trueness of a single cylinder crankshaft
and what to do if it is outside the manufacture spec. The process is the
same for 2-stroke and 4-stroke crankshafts.
This demonstration was filmed in the lab at Western Iowa Tech Community
College Motorcycle and Powersports Technology Program. If you would like

Crankshaft Balancing Counter Weight Reduction
This big block Chevy engine is getting a trim job on the crankshaft counter
weights because we are installing some .400" longer connecting rods with
some very light forgerd pistons. We had to remove a total of 400 grams to
get the crankshaft to balance correctly. Costa Mesa R&D Automotive Machine

Static crank balance
Testing static crank balance on a Honda CR 500 after some balancing is
done. The steel bar replacing the piston does weigh 54% of piston.
Rephased XS650 with Jack's D-Shaped Intake Ports!
700cc with JE Pistons, 277 Rephased Crank, Early Camshaft, 277 Pamcopete
Ignition and all the normal goodies we do to an engine at Hugh's HandBuilt.
All but 1 exception. We spent the last few months with "Jack" from the
forums, and he's taught us a TON of new ways to get some flow into the
heads on these engines. This particular engine has had the intake runners
"D" Shaped, with a raised floor and some healthy 2nd turns, and slightly
shrunk in diameter to raise velocity. Very special thanks to Jack for
taking the time to hang out in the shop with us, and show us a few tricks!
Red Hot Rephased XS650 Engine Hugh's HandBuilt 277
This engine came to us as a bit of a problem engine really. Customer
brought it to us, as another shop had tried to build it, and looks like
they were simply in over their head. Things were shimmed wrong all over,
the clutch was assembled incorrectly, the valves were hitting each other,
the cam was too aggressive, shift shaft was binding in the cases, etc...
We tamed it down a bit and brought it to life. Hugh's HandBuilt 277 Crank
and Camshaft, oversize valves, 5th gear OD, all of our clutch tricks
including a "7 into 6" HHB Clutch swap, 750cc Heiden Tuning Big Bore,
Pamcopete 277 Ignition, HHB Permanent Magnet Alternator swap, and of course
all of our standard rebuild tricks - enjoy and thanks for watching.
PS - don't mind the oil leak from the oil filter cover, the owner has a
custom oil cooler that will be installed there - so I just used a junk
cover here for initial fire.

Engine Building with Rog - Hone and Measure - HD
Here are some engine building videos from my old man, Rog. He explains the
honing process and how to measue with a dial bore gauge. We are working on
a Ford small block (351 Windsor) with a .030 over-bore and it wll have a 4"
