Paso 750 Rear Tire solution (160/60/16)

[hardo]

Hi Hardo,
If you want you can show up ones, and I can give you details. I did the conversion one year ago on my paso 750 and it works perfect (see pics on page 4). I ones started a documentation to put it here on the webside. But had no time to finish it (to much work). Few month ago could get a cheap and nice 906. I will do the conversion on it soon. If you are one's near Bern let me know. If i don't mistake I've sent you my coordinates already.

thanks pasoalf,

I would like to show up soon. I did go for the Avon Azaro combination an also got an okay from the mfk (in the "Fahrzeugausweis"). even though the 180 / 60 version is from the aesthetic point of view better, i am very happy with the performance of this tire combination - it is such a difference to this strange michelins from the 1980th. it would be great if we can meet in order to compare the driving abilities of the different tire options. here is some information about my conversion:

Got this reply today from a "Scott" @ Shinko..."The SE790 Journey should be available late spring to early summer after full testing is conducted."

The SE790 is the replacement for the Shinko 747/757 tires. Hope it will be a narrow enuff tire to remain the "simple solution"...

Terry, you must be already a year behind. Why not take an old sprocket and turn it down?

I figured I'd add a post to this thread after already sending a couple of PMs to G (paso750)...

I have finally completed the sprocket shim modification and ridden the bike about 100 miles. I'm still very cautious about the modification and am keeping a close watch on the bolts for the rear sprocket and the front sprocket shim mod to make sure none of them loosen up for any reason. I have marked all the front sprocket bolts with lines for orientation and left the sprocket cover off for quicker inspection, and visually inspect them often. The longest, non-stop ride so far has been a 30-mile commute into work today.

Right now I am using a used Dunlop D250 with a highly worn Michelin A59X on the front. The front tire will probably be changed this weekend, as it is going bald...like me.

A possible "definitive" solution for the Sprocket alligment is to use a SECONDARY Gear Shaft from a SS600-750/M600-750 form a modern Engine.

they are nearly identical and can be swapped with very little mods (VERY LITTLE).

I did this in an old 750 engine I fitted on a modern frame (with a 916 rear end) and with the new shaft the sprocket is more esternal, aprox 30mm (over 1")

here is a comparison between the two (original on the left, SS750 on the right, the output shaft is the one with the GROOVE):

This is true, but I am not splitting my cases just to swap the output shaft. Paso750 stated somewhere in this thread or another, that he now wishes he had swapped the shafts when he had his engine apart. If I ever have to split my cases, I guarantee I will replace the shaft.

I always wondered if the output shaft of a 900 (906) would fit.

On the 750 no because the P750 has a 5 gears box , the 900/906 is a 6 gears box.

BUT, I bet a beer that the 900SS will fit perfectly the 906.

In Ducati they are preatty lazy , a lot of parts are interchangeable.

I have marked all the front sprocket bolts with lines for orientation and left the sprocket cover off for quicker inspection, and visually inspect them often.

Silly me, I marked the front sprocket bolts but not the rear one, thinking I could just visibly inspect them each time I stopped. I checked them when I got into work today to discover that every rear sprocket bolt was loose and one had come out far enough to lightly tag the swingarm (heppen in less than 30 miles - from the house to work). I'll mark these with orientation lines, too. The front sprocket bolts are holding up well, but I am only up to about 150 miles since the modification.

Interestingly, I picked up a new Dunlop D250 rear tire for only $100. They typically seem to be running $180-$230.

I picked up a 180/60/16 Shinko 757 off eBay and just put it on today. I shaved the ridge with a Stanley "Surform". As it turns out, I took not quite enough to completely clear the chain so I'll get to that again later in the week.

Not knowing any reason why not, I turned the eccentric so the axle is at the top. In that position, the ride height feels pretty much the same as stock. Also, when the bike is on the center stand, the rear tire has about the same ground clearance as stock.

As for how it feels to ride...? I just got back from a lazy 15-20 mile ride on some curvys...so far so good. With the stock Michelin front tire, it felt like it wanted to drop into the corners a bit more smoothly than before.(does that make sense?) The 38 tooth sprocket feels fine but as noted above, I still have to shave more off the tire's chain side ridge. (anyone know how much is too much?)

I'm just trying to continue to enjoy riding my favorite bike of all time without destroying that look...I'll get (a little bit) jiggy with it after this tire stuff jells.

I'll add fotos later in the week.

OK, here's a foto (complete with a greasy thumbprint right in the middle) showing my '88 Paso with the Shinko 180/60/16. Still haven't put many miles on it but so far, allz well.

The Shinko Podium 006 works well on the front with that rear for me.............

Thanks, I'll be ordering one in the next few weeks...in the meantime, the A59 Michelin seems to behave OK.

Hello
Iám new to this forum and i own a paso from 1990 and i'am to looking for a new rear tire found a metzler160/80/16 has anyone any experience with this tyre next qeustion is will it fit the paso's rim
The tire is 1.6 cm tahler then the 160/60/16 that space is available on my paso so i think it will fit.

WTF is wrong with you guys..... Either everyone has an engineering degree and works for the govt which makes it necessary to make everything so freaking complicated to justify the wasted years of your life you spent in college to learn nothing..... or have taken so many yoga classes that you think having your head up your ass is normal.

It's this simple, put tire on rim, remount on bike (yes chain and all), wait dont take bike off of rear stand yet.... get out regular old trusty angle grinder like this one - http://www.makita.com/en-us/Modules/Too ... ?ID=316402 Have a friend ect... spin tire by hand at an even and consistent speed while you grind off enough rubber to stop the tire from contacting the chain, (yes just use the normal freaking grinding disk.... yes the flat surface of it you douchebag) then grind off a little bit more just because I said so. By the way if you and your friend are dumb enough to do this without eye protection on good, maybe you will learn that you should by losing a freaking eye.
Now take bike off stand, put on your riding gear and ride the damn thing.... no don't bother looking at the thing again and re over thinking it, just lube and adjust chain, and keep proper air pressure in the tire.... if it rubs a little so what that will keep that side of the chain clean. JUST LEAVE IT ALONE NOW UNTIL THE TIRE WEARS OUT.

So in short only these things are needed -
1. New Shinko 757 180/60-16R
2. Rear stand
3. Angle grinder with grinding wheel
4. Common Sense

I understand that some may be offended by this post, those will be the same ones who do not have #4 in the above list. My suggestion to them is to sell all motorized transport in there possession and utilize mass transit as a favor to the rest of us, and for the saftey of society in general

I just read on another forum (Concours.org)that 757s have been recalled and that "757s won't be back in production...the replacement tire is a SE790 Journey"...??

Supposedly, you can contact Shinko through their Facebook page.

ha ha! brilliant!!!!
