Flanders chain lube was a more popular chain lube as I was around the Indian shop but The bike riding car dealership I worked in bought this chain lube by the case and we employees split it up between us. Anyone else apply this painstakingly on each roller and seemingly every other gas stop on a trip? Photo courtesy of Rotorious as he had to wait for me to apply the stuff!  |

This is from one of the many cross-country trips to a Lemans America Rally. It is one of many taken with Tim lubing his chain on that trip. I put together a photo album of the trip, and that was the theme. Here we are here, and here we are there, and there's Tim lubing his chain. Most of them from interesting angles like this.
I could drink a soda and eat a sandwich in the time it took. ;-}
But then there are many of me in humorous situations from those trips. Such as the one to the left, my icon pic, with an RE tank attached to my hip. Courteousy of Tim. |

Looks like you missed a bit there Tim. Better do it all again!  |

I will have to get another picture attachment as I just uncovered a gallon of chain lube. Should last me this riding season. Tim |

What sort of rear sprocket is in this photo? Its funny, just yesterday I was just watching the 70's Suzuki movie and I saw a closeup of the beta prototype bike (without the black muffler heat shields) ridden by the cigarette smoking, white jumpsuit wearing RE5 rider. In that video at 8 minutes 20 seconds I noticed that this bike had a different type of rear sprocket that looks just the one in this picture. That raised outer perimeter seems different from the sprockets commonly seen.
The video 12_30_RE5_History.MP4 is available in this ProBoard in the documents recently uploaded by Frank.
Thanks!

 Just a reminder pre production bikes had the 530 chain. After a days of testing, the chains would be dragging on the ground. |

Oh interesting. I just googled PBI and they are still in business making sprockets. I'll keep them in mind if I decide to go with a different tooth count.
Do you run a 42 tooth sprocket for better fuel economy?
Yeah, I'm happy to have the 630 chain. I don't care if it weighs an extra couple pounds as I know that it will last a long time.

When I did my 530 conversion, I weighed all components 530 vs 630. There was almost no difference. I also did this on my GSX conversion, same. In fact, in one case, the 530 was slightly heavier. I'm nearly done restoring my GSX and I've gone back to 630 for that.

Mi hi miler pulled it without difficulty. Only on tight up hill twisties 2 up with camping gear and a taller rear tire would require a quick drop into first. There is a difference and I am not an expert, with the stock setup the chain roams or catches a different spot on the sprocket (hunting type)? However, with the 42 you see the links pattern in the same spot on the sprocket. |

That is great to know. I'll stick with my stock 43 as it seems to be doing an ok job.
Just curious, does your final drive chain ever resonate under moderate to strong acceleration? Mine resonates so severely that it always loudly smacks the chain guard and has lightly peened the front portion of the guard. I have never figured out why it does that. I got the bike with 5000 miles on it and the final chain resonated even back then. This includes being tightened within factory specs and is true for both the original chain and a replacement O-ring chain. And it continues to do that even with brand new, fresh Suzuki cush drive rubbers... Very odd...

Mine resonates so severely that it always loudly smacks the chain guard and has lightly peened the front portion of the guard. I have never figured out why it does that. My chain does the same. Jump to 1minute 10seconds on the video below and watch. You'll see exactly what I mean. That chain resonance occurred exactly where the "grinding vibration" happens on my bike, around 3,800 rpm (YMMV). It answered a question we'd been thinking: does the natural harmonic from the rotor itself gets transmitted through the whole bike exaggerating the "grinding vibration". Experiments have been done in the UK re more pressure on the primary chain tension which does lessen the effect. I'll be fitting a brand new modern manufacture Primary soon and will report if it helps with the vibration and of course a final drive chain that's too loose will make it worse. We had five REs at the dyno that day, mine had the worst vibration and also the highest mileage. Possible that the more worn and loose everything is, the more that primary engine harmonic is allowed through the drive chain worsening the rider's perception of vibration. When I get back home, I'll do a concerted search for that article re the harmonic Al. re5rotary.proboards.com/thread/3020/dyno-day-video-movie |

Al, I haven't, as yet, found the article that specifically talks about a back pressure wave that retards the rotor at certain rpm and diagrams it. However, while searching I came across this that refers to the RE5 and there's plenty mention of reverse pressure (to the point of breaking gear teeth). It seems a feature of the rotary design (as the other article alluded to). I also note that one retarding pressure wave they found at WOT (wide open throttle) occurring at 3,500 rpm which approximates the start of our grinding vibration:   |

Most interesting Wayne,
I see a strain gauge listed . I keep thinking of all the testing done in secrecy back then.

I've read so much about what Suzuki put into the RE5, I'm staggered as to how much. The launch itself was amazing. Was there another Japanese release with everything including Citation jets, astronauts and dancing girls? Was this normal for the Japanese or did Suzuki really go over and above? And before the release, they weren't sitting around scribbling designs on bits of paper from patent to production. Makes it that bit more sad. I hope the "sale of patents' story is true.
