hahahahaha.....15 psi on a 990......hahahahahahahahaaa.....sigh.....hahahahaha
It's not the tire pressure... trust me on this one.
Sand scares the shit out of me in (on) any vehicle, and the fact that there seem to be as many notions about how to ride it as there are recipes for spaghetti sauce doesn't lead me to believe I'd be successful at it on the 990.
I think I'll take the pussy way out & avoid sand at any opportunity.
As I said...rim clean cant be put down to tyre perssure but I figured you guys need all the help you can get... I dont own a horrifically heavy overrated Bajaj so I cant tell what good tyre pressure is which is why you use rim clean method.
Better than your idea anyway genius!
So Meoni had 30psi Mousse in his 950Rally when he won Dakar... A fully fueled 660Rally weighs the same as a 950A with 5L in the tank and they run mousse at about 15psi. Someone better tell the factory they're wrong.. First i've heard of rim clean but looks the goods thanks
Lets not forget that stock rims are butter... Dropping pressure will increase the chances of these against a rock, tree seed, hard dirt or a very stiff desert worm
Well if you run the rims that the factory supplies to Meoni et al and if you have a crew to change your mousse every evening and if you can loft the front wheel at anytime like a factory racer and if you get a new rim at not cost and if you can ride a taco'd wheel out like Meoni...and if you like advice from a guy who doesn't own a 9x0
try 15 psi....
i rode my 990 for my first time in real deep dry 2 track sand in ocala FL (mefo rear and pirelli scorp front prob dropped air down to about 30-35) and after about a half hour i found if i hit the throttle and looked ahead as soon as i started to get squirrely it helped alot
Gas, keep standard amount of air in the tire and then more gas. Get in the upper range of revs and find a spot where you can test riding positions. Try ride with the legs tight around the bike, standing and sitting. Get used to the amount of gas it needs.
What i think when riding is like go skiing and it just control with pushin the footpegs and gas.
Imagine there's a big dog barking and running behind you. Hit the gas, move your ass closer to the rear and aim your sight at where you want to go!
don't go too fast, some trees might not move away from your path fast enough!
On the button!
Its not about tire pressure, its all speed. When its not speed, its about controlling the slide with the throttle to turn or about getting back up to plane speed. If its too hard with a whale, get a KTM 300!
More like water skiing than riding. The slower you go the harder it is to stay afloat.
Not that exotic, only Excels. I leave my bike at 26psi even in sand but have had the occasion of letting the front down and the difference was staggering. A sandy track is different to foot deep powder. Fesh fesh the africans call it, here its called bulldust. Most of the time I couldn't be bothered to adjust pressures. BTW mousse aren't hard to change, no need for a crew just the right tools and technique. And if your saying I dont own a 950 I'd like to say thanks to Sporting Wood for the grommets you sent us, good onya mate!!
A few years ago I was at an XLPOR event and Jimmy Lewis was doing a hands on seminar. We were in a horse arena with somewhat deep soft sand. One of the guys asked what tire pressure he recommended. Jimmy's responce was "tire pressure makes very little difference in soft sand". He went on to say that you should run the same pressure you would normally run for off road.
Not your wheels....KTM team wheels for the racers
No one ever said anything about the difficulty of changing a mousse.
And it is Iceburg that doesn't own a 990....
Advising an LC8 owner to lower tire pressure below 28-30psi in the front is simply wrong....
It works best when you ride it like a 450.
I raced the last 3 years on a 300 XC, and just got my 500 XC-W. So I am used to being able to steer with your legs and throttle. Maybe I will tone done the stabilizer, I guess ultimately I just don't want to put the 990 down! Its just a bigger difference than I remembered. The 990 is still the most fun I've ever had on a bike
Maybe with these gloves . . http://www.advrider.com/forums/showthread.php?t=871079
On the gas! In most any situation, car or bike, a little throttle settles things down dramatically. It transfers the weight back and pushes the machine forward. Both are "forces of good." In the sand, as has been said before, higher speed and a liberal application of throttle makes everything feel so much better. Allow the bike to walk around and find its own path underneath you. As long as you're looking ahead, the bike will follow. Start looking at the ground in front of you, and the bike will follow.
