    So, I went to go for a ride yesterday morning and had to ride off on full choke. By the time I got to the second stop sign the poor little VTR wouldn’t stand the touch of any throttle at all, just stalling out if I tried anything. After sitting at the stop sign for 15 minutes I spun her around and, at full choke, managed to limp back home on idle.
    I had new plugs in and a fresh tank of 91 and, despite having a theory that that additives designed to fix fuel issues only actually force you to physically fix the problem, I had put in a bottle of LiquidMoly motorcycle fuel system cleaner.
    After a bit of sighing when I got home I realised the only real solution was to take the carbies off and clear the slow jets. Even if that wasn’t the problem I was likely to find the issue if I bit the bullet and got to work.
    I was quite nervous about this as I’ve never taken more than the tank off a bike and had certainly never taken a carb apart.
    I took my time and took lots of photos as I went, to help me recall exactly where things (especially pipes) had been before I removed them. Got the carbs off, opened the float and removed the slow jet. The bowl itself seemed pretty clean, the floats were in good shape and, when I first checked the tiny holes in the end of the jet it all looked spotless. But the whole thing was actually physically blocked, enough that I had to clear it with fine wire before ‘rinsing’ with carby cleaner. Since I had everything apart I also stripped and cleaned the fuel cock.
    By yesterday evening, I’d cleaned everything and put most things back in place. This morning I went through the small struggle or reattaching the coils and then filter box and tank. I filled up, reconnected the battery and fired it up. After a few seconds to get fuel back through the system she roared to life, trying to idle at 7000 with no choke at all. Wound the throttle stop back and she idled perfectly.
    I’ve just returned from a test run and the little VTR is one happy machine. It revs cleanly all through the range, runs smooth and a bit quieter and has a shitload more power than when I bought her home.
    Given this was my first significant job on a motorbike I am very happy and pleased as punch that everything worked properly.

    Taking that first step can be daunting and a little nerve racking but the end result justifies the move.
    Very well done mate, all that's left to say is....ENJOY THE RIDE :thumb_ups:
