Twisted my crank?

[Craig]

www.aperaceparts.com has a crank for sale in the used section

[jjnorc]

Have all the tranny pins (roll pins) and "C" clips.
Doesn't look so complicated once it's all apart.
Got everything laied out on the bench in order.
The Crankshaft is on it's way to Florida to Falicon.

I'll have time to clean, check everything else.

Have you got a stock clutch hub? Look at the backing plate/springs good. They are extremely bad to break on your model.

[jjnorc]

Cluch looks to be in good shape. Getting new springs and
fibre disks. I think it's the stock cluch. I bought the bike used
w/4500 miles on it. 40,000 on it now. I don't do wheelies
or holeshots/dragrace so I've never thought there was a need
to replace it. Thanks for the headsup.

Got the Crank out and everything else looks ok.
Gonna send it out to get straightened at Falicon
today.

Does anyone know who stocks Gaskets, seals, rings etc.
I was going to go to the local dealer but they take too
long to get parts in.

Bikebandit.com sells complete gasket set for under $100

When I did the top-end on my 450 last year I got the rings/pistons/etc from ronayers.com...

[jjnorc]

Got Cam chain & Gasket set from Partsnmore
Cluch guts from DennisKirk
Oil seals from local dealer (in-stock, wow).

Still looking for rings, I'll try Bikebandit.

Falicon has my crank and said it should take about a week or two
so I should make my trip to Lake George.

Thanks all for the help.

How much is the crank work gonna cost you and what are they doing?

[jjnorc]

I haven't got an exact price but they sent me a catalogue. Looks like it will be around $300 + to inspect,straighten and weld it.

[cbxchris]

I hope they don`t call you as they have me before. I have sent cranks that I know were good...they came back in a box disassembled and I was told they were unrepairable. I sent them to another race shop and ran them for years. Crap like that has really hurt falicon. They have since been sold so I do not know how the new owners operate.

[jjnorc]

Good news, Falicon can re-index and weld my crankshaft.
No problems, It's gonna cost $378 plus shipping. They said
it should be done in a couple days.

There's a lesson in this for all. If you see fuel dripping out
the overflow or airbox drain, REMOVE THE SPARKPLUGS
before you turn over the engine. It could cost alot of money
and time.

The only good thing to come of all this is I got a chance to
tear the engine down and learned alot about where I can
get parts and services to make the engine go really fast
if I ever decided too.

update

Got all the parts, bottom end is together. Took the time to polish the intake ports. Will install the new rings and put the top end together tonight.
Got parts from: Dennis Kirk, PartsNmore, Bikebandit, local dealer and Crank re-indexed & welded by Falcion.

Looks like I'll make Lake George (americade) after all, as long as the bike runs after it's all together.

Thanks to everyone who gave me advice.

Well, going to Lake George on a Yamaha XJ650 (buddies extra bike).

The GS won't stop smoking, uses a quart of oil in 100 miles.
Replaced the valve seals, honed the cylinders. Rings just
won't seat in. Falicon crank work is good.

I ran 200 miles at 2500 to 3500 rpm (very difficult). By doing
that I toasted the RR or battery, Stator puts out most voltage
at that rpm. Will figure that out later.

Going to have it bored oversize and get new pistons.
Guess I'll have the valves and seats done too.

Hey Hap, what pistons do you use in your GS?

Anybody want to buy a 81 GS1100ex?

[dgeorge]

before you overbore check and make sure the oil rings are right. The ends should just be touching each other and not overlapped. I'll try to post a picture if you need it to understand what I'm talking about.

[jjnorc]

dgeorge,

I would like to see the picture. I'm going to get another set of rings
and lightly hone the cylinders again. I checked the gap on the top rings
and they were right to spec in different spots in the cylinders. I did
trim the oil ring spacer but didn't check the oil rings.

Compression is: 165,155,155,165
I have the oil leak narrowed down to cyl#1 mostly and
a little in #2. Cyl#3&4 plugs look good but 1&2 are oil fouled.
Other than the oil burning, the engine is running great.

Did you make sure to stagger your oil control rings?
