chain

Post by plasmid »

Greetings,

Is it normal for the chain to be touching the center stand pad (for lack of a better word)?


Thanks

guys please keep the pics a little smaller.
The chain slider is a normal wear part. Not only does the swingarm move but the chain swings also.
The center stand springs pull the stand up and it will also slightly swing so occasional touching is normal. Just be sure your chain tension is ok.
If you`d like to move the stand a little from the chain you could swap that rubber damper below that silencer with a new/thicker one.

Sorry about the photos - high rez screen.

Checked the archives. Looks like the slider is no longer available?
Do you know what it is called in German?

Indeed. I was lucky to find a guy who still had three new ones. :)
Don`t really know how they are called in german. Probably "Gleitblock" or "Kettengleitblock".

Time 2 bribe you -.o

They don't cross reference to any other models (besides, I guess, the 750S, 851)?


Looks like Paso parts availability is worse than any Alfa, Ferrari from the 70's.

Most engineering shops can sell you a bit of plastic ( I dunno what it is :lol: ) block , mine was 100mm x 100mm x 15mm thick . remove old one ( there is a screw somewhere under all that gunge ) and you will see that its a simple job to hacksaw and file yerself a new one. Depending on how wild your Mrs is you might want to save yourself a trip and just chop a hunk of the kitchen chopping board :) :) personally , I wouldnt do it again :lol: :lol: ( just while we are on the subject ) , emery boards are a good thing when the sandpaper is to far away, hint: after you've wreaked it get rid of it ( not the w/shop bin .... to obvious ) and she'll think she's lost it :) :)

I think delrin might be the material of the guide block. It looks to me you could bend to restraighten the bump stop support on the silencer and give yourself a little drop in the centerstand height. It seems to be smashed in a little. Then too, if the bumpstop bracket has been bent the other mounts may have been tweaked as well. I'd check the alignment of the cans and the upper mount to see if it's been bent. Loosen the clamp at header. A good hobby shop or hardware supply might also have lengths of the delrin block.

Yes, Delrin readily available, easily machinable by the most ordinary means :beer: :beer: :beer:

I think more likely from a tip over in the parking lot or garage. A hard enough touchdown in a turn that would bend brackets and move the silencer would probably lead to or be a result of loss of control.

However, if dropped or knocked over to the left, the stand arm can be pushed into the pipe. In plasmids photo, I think I see a witness mark on the pipe just above the arm, where it looks like this has happened in the past.
My paso was knocked over by being bumped in a driveway. Bodywork survived but the stand had to be straightened out and silencer loosened and re-adjusted. The stands leveraging arm and silencer caught most of the weight (while protecting the whole left side). I don't recall noticing at the time, but it probably reduced the gap between the stands guideblock and chain as well.

It was bumped or laid over at some point - visible on the center stand.
Is the support with the rubber pad supposed to be completely straight?

Exhausts look symmetrical, although one is Ducati and the other Brevetti.

If someone with original cans could post a photo of the center stand pad that would be great.

Hey,

No one has an original left exhaust they can photo the center stand pad of?

Would like to see how straight/angled that support is supposed to be.

Thanks

I would for you, but am not in my home state now. I don't think it is bent drastically. Mainly the bottom portion where the rubber inserts. level that out and possibly move it a smidge outboard is all that may be needed in my estimation. If I can insert this image, I drew where I suspect it ought to be......maybe that will help.


I saw the small bend to it mostly as an indicator that it had had an impact which may have raised the exhaust a little, in turn raising the center stands resting height. You may gain a quarter inch or so by straightening the bumpstop, if that. As mentioned by another a larger rubber insert may be a good solution. You don't want to crack the shell of the silencer during the bending so be gentle.
