Salut Michel!
Yes, I need a minimum of 20 (because the UK ROC will buy 30). My problem is that because the order to RK will be for 50 rather than 100 pieces, the price will be much more - around 260 Pounds Sterling (and might even be even higher as this price was given a year ago). I wrote to all who originally expressed an interest when the anticipated price was to be 160 Pounds (hoping I would get 100 orders) telling them that the price was now likely to be around the 260 mark, and interest at this price has kind of dried up. I will email them all one further time to see, once and for all, whether there is still a demand at the higher price.
David

Hi David,
First of all: thank you for the effort! When we want to keep running our bikes we definitely need these chains! I am still interested in at least one chain, maybe two....
I hope everyone who drives the RE5 will see the need for a purchase. I will mail some friends who might be needing one too....
Cheers,
Michel

For those of you thinking they don't or wont need a primary chain then here is something for you to ponder. I have recently been working on a customers bike and I had to have the clutch cover off a number of times for various reasons. When I first pulled the cover off I noticed a patch of dark oil under the clutch assembly it looked and felt like valve grinding paste. Not knowing how long it had been since the cover had been off the bike I just presumed it was a build up of old oil and debris from years of use. I cleaned this all up and put the bike back together and did some test riding on the bike. After about 100ks I had to remove the clutch cover again and sure enough this dark thick oil pasty oil patch was back. Thought it was odd cleaned it out and got the bike running again, after a short amount of running I again had the cover off and sure enough the paste was back again. I couldn't ignore it a third time so I pulled the gearbox cover off to check if the problem was in there. But no the gearbox was fine, what else could be causing the pasty patch of oil? I then happened to have a closer look at the primary chain and there was the problem, the hardening on the individual rollers was starting to break up and it was the fine particles from this that was causing the paste. This weekend I had to pull the clutch cover from my own RE5 which has covered about 60,000ks since I was last inside the cover. And there was the same paste in exactly the same spot! Checked the primary chain and sure enough there is a small patch on each of the rollers where the hardening has started to break up. These chains werent excessively stretched nor was there any extra noise in this area but the chain was definitely failing. I had a NOS chain in my stock of parts never expecting I would need it, but it seems the chain is indeed an item that wears in other ways than just stretch as detailed in the manual. This could be your one chance to buy a spare chain which I think sooner or later we may all need if we want to keep riding our RE5s I have my name down for a new one I suggest you PM David and put your name down for one too

Hi David I guess you never got enough orders to make it vaiable to do an order of chains? now there seems to be a bit more interest in the RE5 is it worth having another try? regards Terry

Funny you should ask, Terry …. I was wondering the same myself, so again contacted the RK agents here (in the UK) to see a) it they were still willing and able to supply and b) what the price might be today?
I have had acknowledgment of my communication, with a promise that once they here back from Japan, they’ll let me know. That was last month …. I’ll give it a while longer and give them a nudge if I haven’t heard.
David

After too many years searching for an equivalent primary chain and watching Roger try the belt drive approach with limited success I'm going to have a look at replacing the unique re5 pitch sprockets with a standard ones then standard duplex chain could be fitted. Could be a waste of time but if no one has a go then whats the point. Regards Stuart

Just curious Stuart, does the Hi-Vo style of chain offer any advantages?

I have looked into the replacement chains a little bit here in the U.S. As I mentioned in my post about the oil filter with 3/4 -16 threads per inch and there are other parts on the RE that are not in metric dimensions, The primary chain is one of them. The pitch is 3/8 (.375 ) of an inch. This is a very common double row industrial chain size here in the U.S. What I found that was unique about the RE chain was that the inner plate thickness is .081 and the standard thickness of .056 is what the outer plates are. Probably because the inner plates have a larger hole ( weakest link) for the roller bushing and the outer plates have a smaller hole for the pin. This causes the chain to be wider and the sprocket teeth to be spaced wider. This may be available as a custom order from some of the chain manufactures here in the U.S.
But I am very curious as to how many miles member timpa136 has gone on one chain. ( Tim maybe the record holder for the most miles on a RE5)
Tim, how many miles have you gotten from a Primary Chain ?
Regards, Brian

I have sabotaged my mileage on my chain by welding the outer clutch drum expansion ring.Previously pictured.
My Wifes bikes original chain was replaced just because I replaced her Proper at 150,000 Mi.
She is a gentle driver, the bike was not subject to stop light races etc. Primarily all freeway group travel.
Regards, Tim

Tim,
Your bike has gone 370,000 miles I think? what is the longest run for a chain that you got ?

Brian,
Since you asked, I did a little mileage checking and found my hi miler has 378,000 Mi. but only 143,000 on the last proper when I stopped riding it.No excessive oil consumption or loss of compression was ever noted. I haven't determined yet why I began to foul the plug 3 times. Each time I would clean the NGK10 and put it back in at a later date.
Primary chains are so important not everyone put a few away or has a couple of good used chains, I hope a replacement is made possible.
Tim

Ive mentioned this before but all the chains Ive looked at have started to go through the hardening on the pins. But you can only see this by careful examination on the bike and running you would never know. We need some new chains whether we know it or not! regards Terry

From HGH770N who is testing the prototype. A short video showing the new reproduction primary chain organised by member KANONKOPDRINKER in action. Looks crisp and constructed using modern materials and tolerances should prove superior to the original unit:
