Petcock issue
« on: August 05, 2008, 12:16:00 pm »
I posted about this a couple of weeks ago, but searched for it and didn't find that thread.  Anyway, I think it is resolved.  If you remember, I was "running" out of gas at about 220 miles/2 gallons left in my tank.  It would not even run on resurve.    After reading the replys here, (possibly kinked line) and talking to the stealer, (they thought possibly crud in the reserve line of the petcock) I bougth a new petcock and gas line from Murph's.  Pulled the tank Fri night and emptyed the tank through the petcock by applying vacume to the petcock.  In the resurve setting it was getting a lot of air with the gas so I thought "aha that can,t be rigth".  So installed new one and tested it, same thing lots of air bubbles with the gas.   The previous owner had allready installed the motion pro gas line and it looked realy good so I left it.  When I went to hook it up however, I discoverd that it had a very tight bend between the petcock and filter.  I cut off about an inch and a 1/2 of line and it still has a prety sharp bend but nothing like before.  I think that as was mentioned by you good people here, when the line got hot from setting in the sun all day at work, it was pinching off the gas.  Haven't run it to resurve on a hot day yet, but I think that was it.  
Well...even if you fall on your face you're still moving forward.

Sounds about right, Bill.  Glad you found the problem.    When I first installed my fuel filter, I did the same thing to myself.  Using regular automotive fuel line (WAY thicker than Kawi's OEM fuel stock)contributed, because the bend LOOKED alright, but add some engine heat & I quickly found out otherwise...  Cut off about 3/4 inch, and not a problem since.  Mike B / Gig Harbor, WA

I agree with the "Wize" one that automotive fuel line can really crimp your style when it comes to fuel flow.  If you use it it is imperative to get the length and routing just right or it can restrict or even stop flow completely.  DAMHIK     I'm not at all familiar with the Motion Pro line, but I would assume it would be more like the OEM motorcycle line... is that the case or is it also heavier, thicker, and stiffer?
