Thanks for the posting the good information, Detours.

I have added this link under the Maintenance subheading of the Zongshen RX3 Sticky thread, located at the top of this Dual Sport Forum.

About 2 hours ago the Hanjin Germany was located due south of Mednyi Island, Kamchatka. The last two islands of the Aleutian chain belong to Russia, and Mednyi Island is the easternmost of those two islands. Here are some photographs from the island.

The Hanjin Germany is sailing east at 11.5 knots, and is approaching the International Date Line, and Attu Island, Alaska.

The last recorded location of the Germany was:

LAT: 52° 57' N LONG: 167° 20' E

About 45 minutes ago, the Hanjin Germany crossed the International Date Line, and entered the Bering Sea. The vessel is tentatively scheduled to arrived in Long Beach on March 10, at 9 PM. Berthing time is currently scheduled for March 17, at 5 PM.

The Germany will most likely sail across the Bering Sea north of the Aleutian Islands, following the green route in the drawing below. The vessel is currently located at the left of the drawing, nearing Attu Island. The ship will exit the Bering Sea by sailing through Unimak Pass, and will then sail in a general southeasterly direction to port in Long Beach, California.

The last reported location of the vessel was:

LAT: 53° 31' N LONG: 170° 25' E

* RX3 WITHOUT CUSH DRIVE HUB *

I can confirm that the JTR 897 44T rear sprocket fits the NON Cush drive hub of the RX3 but does require counter sunk sprocket bolts and centralizing on the hub. “Well it doesn’t fit then” I here you say, well it fits better than the original sprocket!

I was having trouble getting rid of a massive tight spot on the drive chain and found that the bolts to sprocket and hub holes are a slack fit and that the inner sprocket diameter to hub lip was also a loose fit, causing it to run off centre.

By wrapping around the hub lip twice with electrical insulation tape I was able to centralise the sprocket on the hub. This improved the tight spot but was still not good enough, then fitted a new D.I.D O-ring chain with the same result.

On with the new sprocket, this needed only one wrap of tape around the hub lip to create a snug centralised fit.
Bingo! , I was able to adjust the chain without getting wild variations in slack, now well within normal limits.

Took the bike for a 10 mile spin, what a difference, much smoother at low RPMs and gear changes and no chain slap / chatter. Much nicer to ride at slower speeds.

I guess the original sprocket wasn’t well made.

The bike is now close to perfect!

Typical. Thanks for the good info.

Why electrical tape? Out of duct tape?

Duct tape !.........on my new bike .... I don't think so my good man !

I need to save my duct tape for holding my car together

thillskier · 03-01-2015, 04:33 PM

He he Kat! That and JB Weld

! There is hope though, even for us bikers with aluminum motors. JB Weld has now, a "high temp" epoxy, rated at 600 degrees f, I believe..Used it on my shop Dodge Cummins powered head (exhaust port flange).
Unless JB Weld makes a 2" x 2" portable cnc machine, we're screwed, pretty much, If CSC doesn't have these parts re machined (by a supplier with a different and not worn out bushings) CNC machine.
And, JB is a temp fix, plus labor to center sprocket.

SpudRider · 03-01-2015, 02:09 PM

That's great, Katflap.

I'm glad I guessed correctly.

I hope I guessed correctly for the cush hub sprocket, also.

If I may ask, when you measured the front sprocket, did you use calipers?

thillskier · 03-01-2015, 03:55 PM

Thats my primary concern re fly n drive for such a long distance. If I find issues like the sprocket after bike assembly in Cali, and CSC doesn't have the parts (or enough for the Baha riders and us others) yet, what can we do. I have made a few parts inquiriies to CSC (besides options) without any response. Not a no, or maybe, or not at this time, NADA.
Troubling.. I also have tried to get taobao to work for me, but still am unable. Its confusing to read the chinese (mostly) and english(in between), to me. SO don't have confidence re Taobao. WIsh there was some tutorial re that somewhere...

Hopefully with the CSC upgrades you won't have any issues with the sprocket. I have yet to tackle Taobao for parts . I agree a tutorial would also give me more confidence in ordering from it

If you search this forum for 'Taobao,' you will find several good threads on this topic. However, I promise I will post a step-by-step tutorial this evening.

well yes but no , kind of

define calipers , if you mean these

then yes

but if you mean ones that can accurately measure to less than a millimetre then no

Also I cant remember now wether I measured the spline or the sprocket

I didn't realise when I measured that they made sprockets with 0.5mm dimension differences .

sorry I don't own proper calipers
