Unstable ride feeling........

[Easy Rider]

Stiffer sidewalls should cause it to wander more, not less,

I think that depends on the starting point AND whether the problem really is some movement or just a feeling of movement.

When the front went from 20 to 25, I noticed the frame raise up near to an inch. That means that the sidewalls were flexed A LOT.
And I think the problem is more of the "feeling" that it is wandering than it actually moving around much.

BUT......as I have already posted, a second trial of upping the air in all the tires produced little or no positive results. Sigh.
So now the fronts are back to ~20 and only the rear is +5 and that seems to be better; but it might all be "placebo" too.

And people continue to recommend alignment......so that probably is in the works fairly soon too.

Personally, I think that single rear tire has too many straight grooves around it. I know that's a really bad thing to do on 2 wheels.

Even with " Crapenda " tires raised to ...... 50psi ..... it COULDN'T raise the Spyder an inch. Why people make statements that appear to be Facts never cease to amaze me .......Instead of " noticing " or guessing put something that JUST fits under your frame and then start raising the tire pressure to the Max as written on the sidewall ....then try and slide something else between the frame and whatever you have there ........... Please report back the results .....Thank you ...Mike :thumbup:

Just broke the:spyder2: out of hibernation after long winter of great skiing and driveway snowblowing.

After checking the tire pressure ( 18 F and 20 rear), unhooking the batt. maintainer, it started up with a quick touch of the button. Drove the neighbor hood for a little while and checked the oil-- right where I left it months ago ( of course ). Then a blast up Rt. 431 -- Lots of turns--- up the ski resort. About a 3000 ft climb in 11 miles. The :spyder2: handled perfect in the turns ( nanny only reared her ugly head once) and NO wiggles or vibration on the straights . Thanks Doc and Squared Away.

I still think you should go with the tire pressure that the owners manual says to use. And just see what happens. I mean why does today's tires want you to put 44 lbs of air in them when its better to run 36 lbs. But what do I know. I'm pretty much done with this thread. No one listens to suggestions any way. Not to be rude. Or make anyone mad But why try to help. I've given up. There are lots of good people on here that try and want to help. Thanks to you all. I just need to give this one a rest. Have a great week.

Cut me just a LITTLE slack here, please.

It made a noticeable rise. Exactly how much isn't important to the crux of the discussion.

My book says 28 rear......BUT a friend of mine said our dealer told him that BRP recently revised that down to 20.
That seems like a HUGE change to me....and not sure if the story is true.

If the recommendation has NOT been changed, I would NEVER run a tire that much below the recommendation.
I still remember Firestones on the Ford Explorers. :shocked:

Can anyone confirm or refute the story about a revised pressure recommendation for the rear ??

That's where I started. Stayed there for about 2000 miles.
The "problem" continued the whole time.

17# front, 28 rear and don’t over inflate the rear bladder too much...30-35 is plenty in most cases . That seems to work the best for ME now barring any crazy roads or stiff wind!

 

[Easy Rider]

My RTL takes care of the pressure for me.

I have it set at the lowest setting......and it seems to help a bit to have the back end down a bit.
I think it runs around 10 PSI but haven't checked it lately.

Baha Ron bar

I finally got my 2013 RTSE5 out for a good ride since replacing the stabilizer bar. It hunted around the road. I did a laser alignment last fall when I got it together. It was still hard to hold straight. Put a good 30 miles on today with all types of road surfaces and I will say it handles like a whole different and better machine. I run 20psi frt and 30osi rear whith stock front tires yet. Only 14,000 miles on spider. Will definitely put cars tires on front when they wear down a little more.

This has me a bit confused.

What changed between those two "tests" ??

The tires probably had to get reshaped to the new set up. They was use to running one way. Now they have to reform to run another way. Its all in the way the tread is wearing that makes it ride different.
