Pingin its ed off

Alreet?

I had a right turn this afternoon. I put a new throttle/oil pump/carb cable on my mk 2. Set my pump up as it says in the book (at full chat the lines on the pulley should line with the pointer). I started it and warmed it up (stationary) and then knocked the choke off. Soon after it decided to rev its nuts off. Could it stop it ? Could I buggary. It were pingin its ed off. I turned the ignition off (still pingin its ed off), took the plug cap off (still pingin its ed off), turned the fuel off and drained the carb as its pingin its ed off. Eventually the engine cut out. I were really pooing my pants. I thought she were gonna blow.

Ive checked my carb, throttle travel etc etc.
About an hour later I fired it up again on choke. Warmed it and then banged the choke off. A few blips of the throttle and the revs started progressivly climbing and staying there with each blip of the throttle. My arse started contractions again and I turned the keys to off and luckily this time it stopped. I weren't going to see if it were gonna revs its nuts off again........I daren't!!!

What the bloody ell is going on?

On another note, I know of a 2000 AR going for sale with 14k kms on the clock. Its mint, makes the eds look like an FS1E. Asking price is £3.5k and its at Rockets Apprillia in Blackburn, black and red! There ias another AR at A1 motorcycles in Preston for 2.8k but not seen it!

Any help with the above would be appreciated!!

Hello mate
Have you put the throttle slide in correctly? I remember when i was a sprog with my little Honda MB50, when i replaced the busted throttle cable, i put the slide in the wrong way round, and had exactly the same symptoms.

Hi Jackstribe,

thought the slide was pretty much foolproof to install incorrectly. There are pins in the carb body to line the slider up with??

Hi Chris,

The throttle slide will only fit one way - as you correctly pointed out there is a groove in the slide and a pin in the carb body - it is impossible to cock this up.

Am I correct in thinking that the bike ran ok before you put these new cables in? If thats the case then you havent put it back together correctly - suggest that you start at the carb end and work back to the twistgrip.

Let me know how you get on mate.

my fault for not looking!

with some bikes the slide has a cutout opposite the long groove for the pin, hence you can accidentally fit the slide 180 degrees out and find the slide is permanently at full throttle.
i'll check mine next time!!!!

Thanks for the info guys.

I had a look last night at my carb slider and nothing seems amiss. Its funny how it only seemed to want to rev progressivly higher each time I blipped the throttle once I knocked the choke off and the engine was warm?

Whats the quickest way of stopping the engine if it revs its nuts off again?

Chris

Sounds like either the slide is sticking or youve got the idle set far too high. Did you follow my earlier suggestion or no?

...stick it in gear, back brake on, and gently release the clutch?

I wouldn't be able to put it in gear if it is revvin its nuts off would I??

Sorry Bargos,

in response to you asking if it were running ok b4 I put the new cable in , yes it was.

I need to trace the cable back to the throttle now.

Am I ok in cable tying my coil to the frame to stop it flapping about at 150mph?

Chris,

Sounds like you missed something when you put the new cable in - ill bet that the new cable is sticking somewhere along the line, suggest that you follow my earlier advice and start at one end and follow the cable back.

I would have said that the best way to stop the bike from pinging would have been to pull the HT lead or follow Daven's advice - you will be able to get it into gear, you may just have to stamp on the lever!!!

Let me know how you get on,
