mud & low psi

Hey all (who have ridden in MUD) Last summer I was advised to lower My (Fr.& B) tires to 12 psi, for the trails, mostly dirt some 4-8 inch sand (5%?) the next morning a group knowing I had a few issues to the sand etc. (ME, A NEWBIE to sand) said STILL TO MUCH take it down to 8psi. heading back to the trails on a dirt road the top was about 1/2-1 inch soft mud. as I was riding (even slower 20mph?) I felt like I was on ICE! heavy weaving. No I didn't go down but turned back thinking 8psi. was way to little to cut threw the soft mud. (also just 11 months after cracking 4 ribs, then hurting them again two months later falling, while working on the bike in the garrage. TOO NERVOUS??) Is it "NORMAL" for the bike to FEEL like it's on ice in just 1/2inch of mud after/during lite rain? OR TO LITTLE AIR?? HOW LOW, .........DO YOU, GO??

bike hauling and tie down question

What am I missing. I have hauled a lot of bikes long distances, many trips to Utah, South Dakota, Montana and Texas. I have tried using blocks in my forks, but usually do not. I have only experienced leakage on one bike, a CZ with LEAK-PROOF brand seals. More important, in my opinion, is to cinch the bike down tight, but not too tight. Then grab a handle bar and try to move the bike from side to side, saying these worde as you do so: "She ain't goin' anywhere." Sometimes she does, but it doesn't seem to matter much in my experience whether you use spacer blocks or not.

What tires do you have on the KLR and how many miles do you have on them (tread depth)? Personally, I've never lowered my tire pressure, ever. Always made it home. Don R100, A6F

<><><><><><><> <><><><><><><> Mark, I don't air a KLR below about 24 front and maybe 26 rear. I've heard lots of folks say they go much lower. I don't use rim locks and I very seldom air down for most of my riding. But on a long dirt trip over a few days to a week I'll lose a few psi and just let it ride. If I get on pavement for more than a short section I air back up to pavement riding pressures. I do think it's normal for the bike to slide a bit on mud over hard pack. Different tires will provide different amounts of traction and feedback to the rider. My experience is to relax, look where I want to go and add some throttle. Standing on the pegs often helps and did I mention adding throttle. When the bike gets so stuck it will no longer move quit adding throttle, kill the engine and get off and figure out how to get moving again. Only use the side stand if the bike won't stay upright by itself. Same for sand in my experience. The faster (within reason) you go the easier it gets. Leaning back to lighten the front end can help a lot too. I try not to fight the bike and if it starts going off a bit cockeyed I'll try to work it back to the line I'd like. If I can't get back to the line I want I'll take the line I can get. : ) Best, Jeff Saline ABC # 4412 South Dakota Airmarshal Airheads Beemer Club www.airheads.org The Beautiful Black Hills of South Dakota 75 R90/6, 03 KLR650, 79 R100RT . . ____________________________________________________________ Gov't Urges Homeowners to Refinance If you owe under $729k you probably qualify for Gov't Refi Programs http://thirdpartyoffers.juno.com/TGL3141/4d6ecfac981d456ebfbst06vuc

List- Here is a MY little photo story of 'mud'- http://groups.yahoo.com/group/GreatDivideRide/photos/album/1190230325/pic/list you may have to join (painless) to read it; this happened in the Great Basin of WY after rain between Atlantic City and Rawlings, WY. At times, the outcome was questionable. revmaaatin. two animals were hurt during the making of these photos

Mud can be very slippery. Ice is not slippery. Ice is horizontal. Slippery mud can also be horizontal. I've proved that. Robert P. Wichert P.Eng LEED AP +1 916 966 9060 FAX +1 916 966 9068 ===============================================

Yes, it's normal for the bike to move around quite a bit underneath you in mud or sand. If I haven't ridden for a while, it is quite unsettling, but once I relax my grip, get my weight back and remember to keep adding power, it gets easier again. Thats 'easier', not 'easy'. It's still a good workout. Lower tire pressures help, but without rim locks, I won't go below about 14 psi. With rim locks, I can go down to about 8, but not on the KLR. With K270s, not below 20 or so, because of the soft sidewalls, but 14 or 15 is okay on D606s. Also, if the mud is just an interlude in a mostly dry ride, I won't air way down for it.
