So, my TRX is running like a pig at the moment, really rich, can't open the throttle very quickly, yada yada yada. There's a thread about the problems over here: https://netrider.net.au/forums/viewtopic.php?t=67060 I have replaced the needles & emulsion tubes, but to not much avail, it's running better, but I can't get it even close to perfect. It's doing my head in. The jets are standard, the don't look like they have been drilled & it's a brand new stock airfilter.... Carbs are balanced... I have just put some slip on cans on, but surely that would make it run leaner? :-k So, I'm missing something important, & I want to get some more info before I go changing jets, I thought that new emulsion tubes & needles with stock jets would fix my problem... Do the jets themselves wear out? What am I missing guys? TIA!
