    Still no real solution to my low MPG. Mate suggested I had my bike tuned.
    Do I need to take it to a Triumph dealership or can I take it to my local garage? What's involved & how much will it cost?

    Dont take it to a dealer unless they have a rolling road....You need to take it to a rolling road that specialises in Triumphs. You can actively tune the ECU.. Or if it's a carb bike they can re jet it... If its carb then you can take it to most Dyno jet rolling roads....

    Best take it to a rolling road and get a test run done and check the fueling.. They will be able tell straight away if it is running rich...


    Dealer retuned my bike or me and I lost 5 BHP straight away... Could tell as soon as I started to use it...

    What he said... any DynoJet centre can do a power run & see what the fueling is like throughout the rev range. I would imagine you are running very rich somewhere along the line.

    I'll phone around and see what the deal is. Presumably the bike is hooked up to a computer & then adjustments made? Expensive??

    A base run will be £25-£50... If nothing else needs doing... Full tune can be £200.. If they offer you a Dynojet then that's £250+ and then £150-£200 for tune so yes it can be expensive...
    Ask for a base run only just so you can see what is up.. If anything....

    I paid £200 for a fully custom tune on my ECU. 3hrs and 29 miles on the roling road.. Bike is brilliant.....

    You're not sure which one? I'm guessing it'll be the bike. Hope this helps! :smile:
