    What's up with my RF

    It started doing funny stuff on the way to work while following Fat Jim on his Bayliss Ducati.

    It's only running on three cylinders until it gets to about 5,000 rpm then it goes on to all four.

    It's a bit like when it was getting water in the coils and low tension leads.

    Weird. Any ideas on how I can go about diagnosing it?
    And I to my motorcycle parked like the soul of the junkyard. Restored, a bicycle fleshed with power, and tore off. Up Highway 106 continually drunk on the wind in my mouth. Wringing the handlebar for speed, wild to be wreckage forever.

    First, find out which cylinder is affected (bike shop will have a heat sensor that reads the headers). After that....????
    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?

    Interesting. I was leaning more towards maybe a valve dropping, but I'm not sure as it seems to go allright when it revs up.

    I filled up at Pak N'Save yesterday morning and I've done about 80kms before the problem started.

    Ah, so thats your excuse. I had to wait ages for you to catch up!

    You weren't doing too badly from the Lower hutt lights! Man I love it when the front is only planted when your changing gear.

    Yeah, I'm blaming you mate for the bike problems

    Damn that 998 is quick.

    The needle on the speedo was about 5° past vertical catching up with you.

    RF owners will know how fast I was going on the 190mph speedo.

    Have you tried the simple things, like checking the plugs and coils/coil leads?

    you can just touch a wet rag to each header and see which one doesn't hiss.

    I'm sure you would know that you had dropped a valve..! Clunk, bang, grind to a halt..!
    If you love it, let it go. If it comes back to you, you've just high-sided!

    Don't we have a resident sparkplug lead sucking expert somewhere round here?

    Imagine what the duc would go like with someone who doesn't weigh more than the Cook Strait Ferry!

    Anyone want to buy a shiny 998s?

    Put your hands on the Header pipes whilst it is running, which ever is cold is the culprit

    Pull that plug and change with another cyclinder, that will awnser if it is a faulty plug or not

    Thanks for the advice Shaun.

    Just did it, and dammit! The problem's gone away!

    Obviously an intermittent fault.

    Oh well, I need a night in the gargre. Things are just going a little too well lately (haven't been threatened with being kicked out of the house for at least a week )

    Check your plug cap (s). Had a similar problem on the 1100 and it was the retaining clip in one of the caps - was missing, meaning that the top of the plug only made intermittent contact with the business part of the cap.
    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?
