new tires on paso

[ducinthebay]

Check to see if your forks are slid up in the triple clamps.
that's a common trick to get the steering quicker, which is understandable with a Paso. It steepens the rake a bit, but looses clearance.
Also check the pre-load spacers on your forks. A previous owner may have shortened the spacers to soften the forks a bit.
Or, you may have soft springs in the forks.

Thanks for the tips,

One thing is for sure and it´s that my front shocks are in need of service. I just got new seals so have to check on the other things you mentioned while replacing them.

Just an update on the alternative tires I've shod the Paso with on her Marvic/Akront wheels:

I've ridden over 3000 miles on the 120/70 r16 Michelin Pilot Sport and 140/70 r16 Pirelli Diablo and they are wearing mildly, and gripping with veracity. I have no complaints, it seems the 140 is just wide enough to bring great satisfaction into the corners. Good feedback has kept me from riding over the edge. I'm pleased as punch with the rubber: No destruction or injury, just good times up right to the limit.

I don't ride with a pillion. That would overburden the tires.

Best to all, and Happy Mother's day!

OK, it´s time for a little update since my Paso is running again.

What I did was serviced the front shocks (new oil & dust seals), replaced the front brake pads, got a new speedometer-thingy (the one that makes the cable rotate) and also replaced the speedo-cable with a fresh one.

BUT!

The front tire (130/70-16 Bridgestone BT016) still touches the front of the fairing when braking. Not if I brake gently but if I use, say a moderate pressure, theres a contact.

So what to do next? The shocks are now mounted normally, not slid up even one bit. Also the forks are now serviced. I wouldn´t want to cut the fairings to make room for the tire, but it seems that´s the only option left. (Or remove the fairings and make a streetfighter Paso... sometimes I´m still intrigued by the idea)

@ pasoist

i am using a 130 / 70 Avon tire in the front. I do not have any clearance problem in the way you discribe it.

It could be the OIL level in the forks is too low.

You mentioned they were serviced recently, well that could be the inssue.

if the Oil level is too low then the fork travel will be higher when bracking hard.

Check on the M1R manual and verify if they put the right amount of oil ; there is a procedure to measure the height, its important to follow it or the fork will work with an incorrect level and this will ALWAYS cause issues.

what about those short metal tubes that put some compression on the fork springs when the top cap is screwed on. If those are missing the fork would also dive in more.
Btw what`s the proper position of the fork in the upper triple clamp ? Should the top end be on one level with the triples upper edge or should the fork actually touch the steering half ? That would probably make 1cm difference.

@ angelix:

i´m pretty sure the oil level is not an issue, since I poured in/measured the oil myself. The manual says 350cc and that´s what I measured.

@G:

I´ve been wondering the same thing myself. The fork tubes were slid as up as possible (so that the top of the tubes touched the handlebar mounts) before I serviced the shocks. Now the top of the forks are aligned with the triple clamps. So I guess there could be an extra centimeter worth of clearance for the front fairing. Don´t know how the forks are supposed to be mounted. Or is it safe to slide them further down in the tripleclams?

I am not sure if that qty is correct and honestly I would not trust the qty indicated on the various manuals.

the correct procedure is by measuring the height of the OIL level as stated on the M1R manual:
fill the stanchion tube with oil leavinG and air volume of 180mm (with the stanchion tube down to the counterboring in the slider) between the surface of the oil abd the top of the tube.

the level has to be checked without the spring / spacer assembly


Basically when the assembly is compleated, leave the spring and the spacer OUT, push the fork tube down until it "bottoms" then fill it with oil until the level is 180mm from the top of the tube.

Extend the tube, insert the spring and the spacers & ferrule then finally screw on the top screw.

from what I understand you have a serious problem , the fork should have enought cleareance even after fitting a bigger wheel

If I recall correctly the difference between the 130-70/16 and the 130/60-16 is 26mm on the diameter, which means that the wheel is 13mm closer to the fairing.

I cannot believe that between the fairing and the wheel at full compression there is such a small space and this is not even considering the fact that the fork flexes.

The other option is that you might have shortened springs, missing ferrules, shortened or missing spacers or a different triple clamp.
