Ice Bear Mrs. Newbies, has a dual vacume tap ,one in each side of the intake. One line goes to vacum feed at tank, to draw fuel, which we all understand, the other goes to a black box that then feeds to the top of the fuel tank. On the bike the line to the top of the tank was chafed thru, (we only have put about 230 km on bike) Some nnuts way to fix the problem was to take a wire tie and crimp off that line. I had had hard starting with long warmups from day one on the trike. I reasoned the second line was to create a negative pressure on fuel tank to facilitate fuel flow or to eliminate vapors escaping and or to prevernt pressurizing tank. Needless to say when I cut the wire tie closing off the vacum Ms. Ice bear started immediately. Starved out for fuel and died. I attached hand vacume pump to fuel vacum feed ,removed fuel line from carb, got trickle trickle, I then removed line from fuel filter and got flow. O.K. two problems with fuel. There is a third fuel thingie I havent even looked at it till I get a mini fuel filter and replace the vent to the tank. How about it kids am I correct on the tap on top of the tank being a vent that is needed? With a clogged fuel filter at 230km (Black particles like dirt or paint residue, or wrong rubber) I will drain & flush the tank and pull the carb and get the rid of the rest of the crap. Mrs Newbie now thinks the dealer does this stuff because his warranty ends when you drive across curb, He charged his hourly rate to fix fuel guage on a friends three days after he bought it.

89newbie,
You are correct , the line on the top of the tank is a vent line. KUDOS to you for the great diagnoses for checking fuel flow. That is the way to do it, to check if its the fuel filter , pump or tank and or lack of vacumm.

picked up two fuel filters, 7 ft. tefflon fuel line and new clamps after work. Allergies had my butt whipped tonight but I will do it tomorrow. Next thought is this 2010 emissions or is the ice bear built to a higher spec than the 2008 WIldfire. First time I have taken Ice Bear down and see quality in connectors, care in assembly six wires to the CDI, also exhaust has canister in front of muffler I believe is a catalist.
