i am not really grasping your question Don, but unless modified, the petcock is vacuum activated,which means the bike has to be running for the fuel to flow,not running nothing drains,except what little gas is left in the hose going to the carb,if you remove it . --- Don Bittle wrote:

Actually the engine does not always have to be running. It just needs to be producing vacuum. This is also accomplished when the engine is cranked with the starter before it fires and begins running. Otherwise there would be no way to get fuel in the float bowl if it were empty. Of course this only applies to the more common RES/RUN/OFF petcocks. Some KLR's were fitted with a petcock with a prime position. It doesn't need vacuum in the prime position to flow fuel. Walt

Forgive me, but I thought you were looking for a tire that would perform IN Death Valley. As for pavement, I've done two all-interstate iron butts on D606s without any issues, at speeds up to 96.6mph they've been stable for me. Mark

Everyone needs a good laugh on Monday.. Yesterday Jumped on my KLR, set the petcock to on. Started up the road, big smile (had worked the whole previous day on wife's cabin and looking forward to a long ride in perfect temp). A mile up the road and sputter - sputter - sputter, Ah, switch to reserve and; sputter - sputter -sputter - stall Push to side of the road.. Ok maybe need to use my "idiot reserve" Lean the bike to the left to let the fuel move from the other side of the tank... Still will not start.. checked everything over, all good try again, no start after about 15 minutes was rady to call home to get wife to bring truck.. One last look at the petcock.... it was at the OFF position, not Reserve turned it to reserve, started... Back on the bike, u-turn, headed for home... Too stupid to ride today. albatross ride deprived, better that than not having presence of mind to avoid someone in a tank cutting off my path

Oh well, I wish they would make all bikes petcock go the same direction for ON / Off / RESERVE. My Concourse is exactly the opposite direction of the KLR (and hard to find for me) which has got me into some interesting moments in high speed switching to reserve. They are both Kawasakis. Go figure. They standardized the shifting / braking on bikes after all sorts of arrangements in the 60's and seventies. Who can forget the rotary shift Brigstones? Sounded like a great idea for the inexperienced. If you were in top gear you could go one more (down I think if I remember right) to hit low gear. This was all well and good if you remembered correctly the gear you were in. It was however a big surprise for you at speed to think you were in next to top gear but were actually in top gear and went for another gear only to discover you went back down to .....er .... first ... suddenly ....at speed. RRRRIIIINNNNGGG-DING-DING!!!! I rented a few of these in the LA area in the mid sixties. The engineer should have got the idiot award. Criswell

Lets not forget the "other brand" experience. On my airhead the lever has 4 positions, up, down, front and back. Down is "on", front or back is "off" and up is reserve. No room for startup ritual here. You have to think about which bike you're riding. In addition the BMW has a non- vacuum petcock so you had better turn it off lest you find your precious fuel on the pavement. Question regarding this feature. The Concours has a "hydrolock" issue caused by fuel flowing past the float needle and filling the cylinder. Why is this not an issue in the KLR?
