But, Clement Salvadori in his Road Tales column devotes three very nice paragraphs to CSC and the RX-3, and to the virtues of touring on a small bike, even though he has not had a chance to ride the RX-3 either. Way to go Clement! I may pick up a copy of No Thru Road to help pass the time while I am waiting for delivery.

Clement Salvadori is one of the great writers out there. His book on riding through Baja is a must read. It's actually on my nightstand right now. I've nearly got it memorized.

The Zongs appear to be built strongly. Thats why the weight isn't all a bad thing!
Most Chinese forks are very small and not strong, It APPEARS that those may if bent, only the lower portion, but not sure of even that! Crash bars definitely did their job(s), also. STill scary..wheel is definitely toast!

CSC just posted a new tutorial on cooling system maintenance. As usual, I have added a link to this tutuorial in the Zongshen RX3 Sticky thread, under the Maintenance subheading.

Spud, a word of caution on carrying CO2 cartridges. Don't put them anywhere (like near the exhaust) where they get hot. I about blew my neither regions off when my fanny pack that held the cartridges slide down onto the muffler and caused the cartridge to explode going down the freeway. About ripped myself a new one. rj

Egads!

Thanks for the advice. I carry the CO2 cartridges either in my hydration/backpack, or in a front fender bag.

About one hour ago the Hanjin Germany was located approximately 150 miles offshore from Petropavlovsk-Kamchatsky, the largest city, and the capitol of Kamchatka. The city is located on Avacha Bay, and is home to Russia's largest submarine base.

The city was founded by the Danish navigator Vitus Bearing, who also explored his eponymous sea to the north. Bearing named the city Peter and Paul after the two ships in his second expedition. The city has a population of 180,000 people.













The Hanjin Germany is leaving the continental shelf, and sailing into deeper waters while heading east at 9.3 knots toward Attu Island, Alaska, and the Aleutian Trench. The last recorded location of the vessel was:

LAT: 51° 09' N LONG: 161° 06' E

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?

[SpudRider]

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?
