You get endless chains on the average pushbike nowadays.

No. If each is fitted correctly there should probably be no issue with either. I'm guessing that it may be possible to put on the spring clip in such a way that it seems secure, but it isn't IYSWIM. Having never riveted a chain myself I can't comment on whether that scenario is equally likely. Though I suspect, without any real foundation, that the 'loose' side plate on a riveted link is a tighter fit (hence the need for a tool or clamps etc.), and so play is less likely to develop. All I can say, is that going back to the pre o-ring chain days of 5/8 x 3/8, the only time I had chains fail it was the split link. I've also found split links with very wobbly pins when doing sprocket changes and replaced them. -- +-------------------------------------------------------------------+ | Pete Fisher at Home: Peter(a)ps-fisher.demon.co.uk | | Voxan Roadster Yamaha WR250Z/Supermoto "Old Gimmer's Hillclimber" | | Gilera GFR * 2 Moto Morini 2C/375 Morini 350 "Forgotten Error" | +-------------------------------------------------------------------+

They really needed 'em, yes. My old CB750F1 was the last model Honda made with the old weedy chain - the K7 and the F2 got the beefed-up endless chains. A chain would last 5000 miles, tops, on my F1, and need adjustment every 300-400 miles. When they put big beefy chains on the bikes, they made the move to endless at the same time. -- BMW K1100LT Ducati 750SS Honda CB400F Triumph Street Triple Suzuki TS250ER GN250 Damn, back to six bikes!

Just normal thumb pressure required to put the plate on. It was bright yellow, which makes it easy to find when in a hurry in the paddock. Yes, I know, buy less pikey chain. The clip was much higher tech than they used to be though. >There's no lateral force on the sideplate, so little chance of knocking >off the clip. > > Assuming the alignment is spot on perhaps? I suspect that when I was a callow youth on a Matchless G2 that wasn't always the case. The home-brewed Rotarini was not utterly perfect in that department, it has to be said. -- +-------------------------------------------------------------------+ | Pete Fisher at Home: Peter(a)ps-fisher.demon.co.uk | | Voxan Roadster Yamaha WR250Z/Supermoto "Old Gimmer's Hillclimber" | | Gilera GFR * 2 Moto Morini 2C/375 Morini 350 "Forgotten Error" | +-------------------------------------------------------------------+ |
