Injector issues?

    Anyone needed to replace the injector. I seem to be having problems - experienced it once before and pulled it and cleaned it successfully but the problem seems to have returned and the same treatment has not worked (spraying carb cleaner through it under pressure with a syringe). I will try again and also check the fuel pump - it is cycling up but am wondering about blocked filter or not making enough pressure to activate the injector effectively. I will check this as well with injector in place in the TB.

    I was also wondering whether anyone has replaced their injector with a 10/12 hole version, as opposed to the standard 4 hole. These are the same size and come standard on some of the smaller Huskies - I recall discussion on Thumper Talk and possibly discussed here on other threads?

    What are the symptoms? I'm also experiencing some issues, but I'll make a new thread of it :) haven't had any injector problems yet...

    OK problem sorted. Symptoms were that it started spluttering and missing on a ride this past weekend. Would not rev-up and would die on one. Ascertained not a spark problem but fuel - was getting fuel through though ... guessed injector. Pulled the injector and cleaned and tested it. Refitted and still no joy. Checked it in position and it was not misting.Pulled the fuel pump and there was the problem staring me right in the face! Pickup hose had fractured. I guess it really should have had a zip-tie holding it to the bracket so it was not pulling at an angle to the spigot creating a pressure point where it ruptured.

    Good pick up, your initial thoughts were logical and subsequent further enquiry squared the issue away. I am now attuned to this potential issue, so thank you.
