Johnny B Posted September 30, 2006 Author Report Posted September 30, 2006 well she got a 290 jet, put that sucker in there and does the same thing. if i take the entire air box off, and let it suck straight into the carb it seems to run awesome. itll rev up and not bog at all. but when i put it in gear and put a load on the motor it dies. ok another update... it'll rev up clean all the way, without the air box on. it will only start with the choke on, even when its hot. and it sounds like it runs out of gas and dies randomly. i can take it all the way up in 2nd and it'll run up there with no pops or hesitation, but it feels like it loses power at the top. it runs the same with the 290 and 310 jet, but it seems to start easier with the 290. and it'll only run/start with the mixture screw all the way in. any suggestions?

holeshotkid Posted September 30, 2006 Report Posted September 30, 2006 Have you actually disconnected the TORS or just unplugged the wires to the to of the carb. The TORS is the small black box in front of the gas tank. Unplug the wire harness from the box and try it. Quote
NY350twin Posted September 30, 2006 Report Posted September 30, 2006 One thing you should try is a compression test. Maybe its time for a new Top end. Quote
Johnny B Posted September 30, 2006 Author Report Posted September 30, 2006 i unplugged the tors completly. i couldnt see there being much difference between the 290 and 310 jet since it runs about the same with both of them. and it ran like a top with the 310 before.... Quote
[email protected] Posted September 30, 2006 Report Posted September 30, 2006 sounds like its not your main jet , but more or less your pilot ... check out my thread in my sig , i know its for banshees but blasters are basically the same thing just missing 1 cylinder and a can of woop ass Quote

Johnny B Posted October 8, 2006 Author Report Posted October 8, 2006 not to divert anyone from here ,but youd probably get more blaster advise about your problem on everything2stroke.com well turns out it needed reeds, i took them out and one of them was missing. put new yamaha reeds in it, run perfect. gf took it up and down the driveway once, her brother got on it and tried to race my 350x and we went up the street once, he topped it out in 6th... turned around and on the way back he said it just died on it (i couldnt see cause he was behind me) and it wont start now at all... i took the reeds out they are still perfect looking... i cleaned the carb all out, new plug... won't start. took the head off, the piston is intact, it has compression (not sure if it should have more, it wont push my thumb off the spark plug hole... but since the piston is in tact it should have some compression... if i look through the intake ports i can see the piston go up and down and it looks fine... if i try and start it, there is gas in the carb, and in the intake boot, and also on the reeds, but the plug is bone dry. is there anything stupid that could cause this???? please help Quote
