Back to basics. What year is the bike? Given that info the next question is where is the fuel filter or screen. Is there one in the petcock or an in line filter? One of the possible causes given the symptoms I think I heard is that fuel is getting to the bowl too slowly. Not venting the tank could do that but to test you just take off the gas cap and run it. If it fixes it then the cap vent is no good. If it doesnt then follow the fuel. Next down the line is the petcock. If the vaccumm isnt opening it all the way that would have the same effect. vaccumm leak or gunk in the petcock are probable. If the petcock is opening then is there something keeping fuel from free flowing into it. A petcock screen or an in tank filter would be the likely problem on most bikes. Not sure what you have for a year or what kind of petcock the IMS tank uses. but the feed line on the petcock could be jamed up. Fuel line should be easy to check. End of the line is the carb. Is there a filter screen on the inlet? If not then pop the bowl to see if the float is opoening the inlet needle all the way. Could have grit jaming it. Follow it logically from the start and tell us what you find at each strp. Then we can look at what else to check if you havent found it.

Does your bike act like it is too lean or too rich? If it is too rich it is most likely something in the float valve. You ll need to remove your card and float to flush out this valve. If your bike is acting too lean, then there may be a blockage in the fuel petcock not letting enough fuel into the carb. Check your fuel flow from the petcock to see if you have a good flow of fuel. > > I have seen all sorts of junk inside new gas tanks and you may need an inline fuel filter if you don t already have one. > > Fred > http://www.arrowheadmotorsports.com > > > > From: ALFRED > Sent: Tuesday, January 29, 2013 10:38 AM > To: DSN_KLR650@yahoogroups.com > Subject: [DSN_KLR650] IMS Fuel Tank > > > Think I know more than I do sometimes, I disregarded the instructions with the tank (re: venting) and just reattached the fuel and vacuum line to the petcock, added fuel and kept my fingers crossed.

Correct. I have the CA tank too, you just need a vented cap, the petcock hooks up exactly as before. Also, your stalling problem is not a venting issue. The run time for a venting issue on an IMS tank is longer than one minute, more like 5 minutes at the absolute minimum. I've had an IMS tank for years. Fred is right (as usual), you have something obstructing fuel flow, either at the petcock or inside the carb. Thanks CA Stu A13

Great post by the skypilot! An easy way clear the float needle/seat, if it is not completly fouled, is remove the drain screw (3mm hex, right side, bottom of the fuel bowl), and crank the bike; it will pump fuel through the petcock in pulses if you are still using the vaccum petcock. DO NOT LOOK AT THE DRAIN HOLE while you crank the bike as you might get an eye full. Some bikes squirt fuel further than others. Catch the fuel on a clean white rag if you have one; allows you to see the grit or grasshopper parts. If you see 'bubbles' on the white cloth, that is usually indicitive of water in the fuel bowl that you just blew out. It will only be there momentarily, and then quickly absorbed by the cloth. revmaaatin.
