transalp comparasion to klr

[klroost]

If its possible, and someone would like to help me out, could someone go suck on the vacuum hose for the petcock and let me know if it "leaks/vents" down, thru the atmosphere vent drillway in the plastic block between diaphrams. or if it just straight out holds vacuum? I had to drain the tank roadside and found I had to continually draw vacuum to maintain fuel flow. Which left me quite dizzy, because of course this all transpired right after filling the tank. This has me wondering about some runability issues I have with my KLR thank you in advance klroost

It should not leak down. If it does the diaphragm is bad. Walt

Sounds like your petcock is working as designed: engine needs to be running to produce the vacuum in the carb that is transmitted through the vacuum line up to the petcock to 'say' it is OK to let gasoline out of the tank to feed the carb. Otherwise, you have to shut the petcock when parked so the gasoline doesn't flood the engine. Don R100, A6F

The vacuum should hold on the petcock side if all the connections are tight and the petcock diaphragm is good. When the engine's off the vacuum should bleed out from the carb side, not through the petcock. Otherwise it would be like a vacuum leak- although it couldn't be very large if you managed to pull it open by mouth suction-

Does anyone have a fuel petcock for an 03 KLR650 for sale?  Or where is the best place for me to look online?  Thanks in advance for any help.    Larry '03 KLR650

Hey Transalp, I am thinking of adding another bike in the future, while keeping my KLR. If you have owned both the KLR and Transalp...how would you compare the two. I am thinking of the Transalp for more regular rides from California to Texas.

Is your stock petcock leaking or is it missing?  If you need a rebuild kit for your petcock, I sell those or I can get you the complete OEM petcock from Kawasaki.  What seems to be the problem with yours? Fred www.arrowheadmotorsports.com
