How much is enough

DUC906,

Where did you get that roll around thing the bike is on??

36 years ago I heated a cylinder head in my first wife's oven, She is now my ex wife and I have hot plate.A very good hot plate. It is 30 years old and still works great

Ha ha ( Hi Higgy ) mine was the dishwasher , I dont mean my wife was a dishwasher ( well , she was that day ) but they are good for cleaning bike parts , specially if you nuke em in the oven first

Just thought I let you know how I'm getting on with this.Thanks for all the advice.

You need to be mindful of the chain running in a straight and true alignment with the 2 sprockets. Running them offset will give you problems.

The tire at the front cross section just doesn't have enough clearance. At speed the tire will grow in diameter and likely rub.

See this site for a mod that has been done:

I borrowed the lazer liner from work and set it up on the sprockets and found that the front sprocket needed altering as well.To fix this I turned the sprocket around.


Then I pulled the swingarm out and and modified the back of the cross member,I cut through the welds in the center and on either side and pressed it in.It now has about 12mm clearance between the tyre and swingarm,will have to wait and see if that is enough.

This is after I welded it back together.I had to press the arms apart because they pulled in 4mm from the welding.

The front guard I've had to pack up 6mm to clear the tyre.
All I've got left to do is extend the center stand by 25mm so that it will work and maybe get a side stand off a 907 so that it doesn't lean so much.

DUC906,

I made this up myself because I have limited space in my shed and it makes it easier to move around and park against the wall.It cost me $40 for the wheels and the steel I grabbed out of the scrap bin at work. ;)If you like I could do up a cad drawing and send it to you

you can also buy them, but they are not that cheap (here ca. €129)

... and pressed it in

how did you do that?

I used a combination of a hydraulic press,large hammer & copper dolly.

did you fix the rear end of the swingarm with a large spacer while doing that ? I would be afraid that the swingarm ends would move inwards when applying pressure to the middle section.

I did have a block of wood jammed in between the arms to stop them from pulling in when I welded it.They still pulled in by 3.5mm but it didn't take much effort to push them back out with a hydraulic jack.

re: roll-around thingy:

here's a side-stand variant for $100.

thanks for the infos, i think i will also go for the conversion 180 / 60 16.

the advantage of that bridgestone tire is: it has only 179 mm widenness (Avon: 182, Dunlop: 183)

disadvantages: as far as a know, it is made for the front wheel (!) of a goldwing

just a simple question in regarding the clearance to the swingarm (front):

moving the excenter to, e.g, 4 clock position should give you some extra space. you may have less
adjustment possibilities for the chain but before making changes on a producation part of the paso, I would rather
try this.

am I wrong?

thanks for your answer, hardo

[paso750]

1,5mm per side don`t make a huge difference therefore I`d recommend the Avon. You should make up your opinion after calling the tire manufacturers and hear what they say about using their model on a bike like the Paso

[hardo]

you are right, but i am afraid of the diameter size too: e.g., avon is 630, dunlop (D 250 F) only 615.
that is quite a difference and should help because there is very little space at the front of the tire / swingarm anyway.

to come back to the point with the excenter: is it a problem to go away from the 6 o'clock position in order to gain some additional space in the front (swingarm / tire)? am I thinking to simple?

[paso750]

no, it`s not a problem. To the front there`s enough clearance depending on excenter position with the Avon.
see here, I had made some pics:

pasoalf (also from CH) is using a Avon Av72 also, see previous page in that thread

thanks a lot for the info!

some pictures would be great! hardo
