Odd feeling when making a left turn..what is it?
I recently changed front and rear tires on my 04 R1150RT; went from the Metzeler Z6's, to Mich. Pilot Road 2's. I replaced the rear tire 1st, and then the front tire about 1,000 miles later.
But here is the thing....
Within about 300-400 miles after changing the rear tire, I started to feel a very odd sensation. When I lean into a low speed (10-15 mph) left hand turn the bike almost feels like I have a flat tire; if this is happening while making the same sort of right hand turn, there is very, very little, if any, similar feeling. For a while, I thought it might have something to do with the old front tire as it was pretty worn on the left side (which seem to be typical...to a degree due to weight imbalance); but after I changed it out for a brand new Pilot Road 2, there was no difference. Also, if I am leaning into a left hander at a higher rate of speed, it feels normal.
I have placed the bike on the center stand (several times), and I have tried to see if there was any movement when holding the tire in the 6 and 12 position; and again at the 3 and 9 position. Nothing, nada, no movement at all! I also tried to see if I could wobble the rear wheel from side-to-side (left to right), and again no movement at all.
Both tires appears to be correctly seated, and mounted in the proper rotational direction, and there does not seem to be any unsual wear (approximately 1,500 miles on the rear tire, and 250-300 miles on the front).
I can rotate the hub (without the wheel attached), and there is a little bit resistance (bearing load resistance I assume), which I would think is normal, but there is no feeling of roughness or unusual grinding sounds. Seems normal; I think.
Lastly, I recently did a transmission and final drive change, and again there was nothing unusual, clean and clear. What I forgot to mention was, the bike has 40,700 miles on her as of today.
So, I am seeking the advice from the collective; any ideas of what this might be, and way only on the left turn/lean side??
Wobble In Rear After Tire Swap
I need to reopen this old thread since it sounds almost identical to my situation. I've got a '02 R1150RT and recently replaced both tires. I went from PR2's to Z8's. I had my local dealer mount and balance the tires and then I mounted the wheels to the bike. The rear end acts like Jeff's bike in this thread, twitchy especially on grooved pavement at moderate speeds (40-60mph) but appears to be less noticeable at higher speeds. Feels like it's flat going into turns, almost like it wants to dive in.....sometimes. No play in the rear wheel at 3-9 or 6-12. I've changed the air pressure from 42 to 46 in the rear, and 40 to 42 in the front with no noticeable effect. I've taken both wheels off and retorqued them and nothing. I then took the bike back to the dealer to have them do a safety check and all they could find is a leaking fork seal. They said the suspension felt "soft" but didn't take it out on the highway. I changed the fork seals but that didn't help. Today I changed the final drive oil to see if there was anything amiss and it came out relatively clean, dark but no shiny bits with a little black fuzz on the drain plug. The bike has 62k on it and both shocks were replaced at 42k with OEM ones.
I've looked at the bead on the rear wheel and don't see anything amiss on either side. No noticeable bulges. I'm looking for ideas before I resort to just dropping it off at the dealer and telling them to figure it out. I've put about 1000 miles on it thinking I just needed to break the tires in but it just doesn't feel right.
Help! Any ideas are appreciated.
