So Flick is still not idleing right :(

[dread_au]

I pulled the frame mounted petcock apart and found some fine dirt/rust in it. Drove me nuts trying to work out what was wrong with the carbs when this was the problem. Only worked this out when I came homw and found the airbox full of fuel

Given that you checked everything in the carbs - my guess is that you have a tight valve.
But that messing with stuff like idle screw makes me wonder if anything is wrong with it.

The thing is valve goign tight can creep up on you ... however it can creep up very rapidly if the temperature goes from hot to cold. Yes hot to cold as in summer into fall. Not the reverse ... so you may have had it wear faster than the temperature change. So these are my Q's for you - what was the first symptom of it doing this. Then as soon as it did that, did you ride it long distance in 1 run, but I guess dont even have to be that long of a distance, 50 miles could do it. Either way a tight valve has to be fixed and fast. The valve dissipates heat by sending ti into the head @ the seat, if you're open there you're not sending any heat away ... you'll burn it.

Cool.

I second the tight valve suggestion. Common symptoms are rough idle and backfires.

I'm beginning to suspect a Valve as well. I did the water squirt test and it seems the left is running hotter than the right. I've never done valves before the shop was supposed to take care of that on the last time I brought it in. 2200 miles ago. Since, I've never done this what tools will I need?

If it was a dealership  that was supposed to do it then there is a high probability they didn't.


A Suzuki shim/valve tool will make it easier for you.

A 10mm, 12mm socket, a longish flat head screwdriver, pliers, metric feeler gauges, 6mm allen key.  Kerry's valve adjustment vid tells you all you need to know.

I use one of those extending magnets to pull the shims out of their buckets.Don't turn the engine over with any shims removed,it will damage the cam lobes.

  MARY have you found your problem yet.? im very curious but could have a suggestion once you have checked your valve clearence ..

[twinrat]

   was changing diaphram on carburettor today and noticed these wear marks on the slide infact on both slides this could be the cause of your hanging throttle ,in any case i have eased the area( marked) to a radius to prevent slide catching on sharp edge ,both carbs have it in the same place and same side  ,in this instance the right side might have some thing to do with the flow.test road bike and no ill effects from this mod..

need this photo to

[twinrat]

have tried to get photo from photobucket of carburettor body where slide catches but all i get is the slide photo 4 times  ,just match the slide to the body and you will see  what im on about .

That's cause you keep putting the same photo code into the post. Bring up both images By Themselves - not within the PB window - and then choose the correct code. Also, feel free to edit your previous posts to remove extraneous images.

When you're on the PB page, put your mouse over the image you want, right click and select "open in new tab" or the equal to the browser you use. This will put the image's URL in the location bar of your browser. Copy that line of code and paste it in as you have done previously.

I think some of these might be what you are after

Thanks Michael those are the images i tried to put on the forum .i myself dont have a problem with carburation ,ive brought this observation of these wear marks to possibly help those who have hanging throttle.I think these carburettors have a tendency to wrack there slides .my slides had fine aluminum haze round the slide guide area .should have taken a photo of it ,so there is some resonance of the slides backwards and forwards in there slide grove.

Hey Rod,

Flick's slide didn't look like that. It was in the body itself and the grooves were very fine. Flick wouldn't start last night or today so he is sitting at work  Looks like we will be grabbing a trailer tomorrow and carting to the BF's house I already have an appointment to drop the carbs off at the Motorcycle clinic on Friday. $75 and they will have it taken care of by the end of the day. At this point the price seems reasonable because the headaches and stress is too much right now. I'm practically working full-time and carrying full-time credit hours in school. So, not much time this next month and a half. I miss Flick being a pleasure not a PITA.
