What pressure you running in your tires?? |
I've been running 37/40 on my LT for last 5 yrs or so. I'm a 150lb solo rider.
For grins I reduced the tire pressure back to 32/34 where my tire mounting shop had set them. I could reproduce the instability issues that folks were concerned about over 90 mph.
So +1 for running at higher tire pressures but I dont think that has anything to do with the PR3's in particular. I've run at 37/40 for three different tire manufacturers. (Increase to 39/42 on my rare 2UP runs).

Thank you sir, knowing your weight helps me set mine better, and knowing you can produce the instability helps also.
I am 6'5" and 300lbs, so guess i need to bump mine up some. LOL LOL

Take care and ride safe.

I want to thank all those that chimned in on this, it has really helped me on my air pressure. I went out yesterday evening and raised the pressure to 41F and 43R, (I'm 6'5" and 300lbs) and took the bike out for a ride, took it up to 125 and was riding around 80 mostly, stable as can be, still a good amount of tire on the ground by looking at the patch after i stop.
Only prob i seemed to notice, is that about 115 it just felt really light, but I'm sure that's due to less tire on the ground, but I don't tend to ride that speed that much, but as far as the handling on the hwy curves, it was great, the bike was super responsive, lean left, it went left, lean right it went right with total ease..

The only thing we'd feel at between 115 and 125 in the UK is the long arm of the law - that's a burn your license and get used to prison food speed over here...but great to know an LT is stable up there.
Cheers

Here if they thought you were being a bit cheeky or under 25 then the bike gets impounded too.
ET is up into three digits mph;

Ohh, If i was caught, I would get at least a few hours in jail, plus lose my license. So i dont travel those speeds too often, I was just out testing is all, But as far as running close to triple digit (MPH) The fwys here in So Calif you almost have too just to stay ahead of everyone..

Good on you Mate
I lived in Germany for a while and even if you floored the ol bus, you more than likely ended up in the slow lane... 
Tyre pressures can go down, by natural attrition, awful quick, so keep up them checks. I do it every second day |

I ordered a set of PR3's from Motorcycle Superstore & they showed up in 3 days 
110/80ZR-18 for the front
150/70ZR-17 for the rear
These fit on the stock LT rims 
Thanks to Bill a.k.a. "whyoldbill" and Jeff a.k.a. "old guy old bike" for the early trials with this tire size on the rear.
This was the first time that I took the wheels on & off myself and had a motorcycle tire shop do the mount/balancing.
Instructions in the owners manual for changing wheels are good. Couple of tips......
1) Put a 1/2" board under the center stand & the rear wheel will come off without having to remove mud guard.
2) Once the rear wheel is back on have a helper apply weight on the rear seat to tip the bike backwards & take the weight of the front wheel. Then install a wooden block below the engine to support the bike. At this point both the wheels will be off the ground & you can remove the front easily.
 |
Did you notice any significant lowering of seat height?
TIA

Nice. Do you still have to remove the exhaust? I could not remove the tire without pulling it off. And that was with the stock sized 140/80x17 Avon Azaro.
Note: I don't run the stock exhaust anymore, I have a Remus, which weighs at least half what the stock unit did.

Nope. The beauty of the board is that you can change tires without having to take anything else apart. (I have a stock muffler).
Once you have the weight of the bike supported on the wooden block there is nothing keeping you from taking off BOTH tires at the same time. Then while your tire shop is putting on new rubber, you can check/replace the brake pads.

I guess the stock muffler is indented on the inside or something, because the tire won't clear the remus without removal. Board or no.

Correct - the stock muffler is indented.
