Hiya, Today I went out for a spin, (Suzuki Across) after pissing about installing 12V system for GPS (all good with that). But I get up the road about a block and all of a sudden the bike is revving at 9k and won't come back to idle speed. Throttle seemed to behave correctly so I didn't suspect a cable issue. I pulled over and turned the bike off - started it up and it revs up to 9k again. Pulled out the old swiss army knife to immediately look at the idle adjust - the Across has that stupid rubber grommet through the side panel arrangement with the idle adjust on a cable thing that goes to the carbs. I knew the grommet was pushed in and floating about so that's what I looked at first you see. I adjusted the idle, expecting to move it a lot, and all I did was move it about an 1/8th of a turn and the bike returns to normal - it's been normal ever since (all day). IS it possible this could be a symptom of a buggered carb slider holder as documented here - http://www.oocities.com/ozcross250/holder.html Reckon I'll be checking on those holders anyway as the bike is at 27Kkm. Also, the bike seems really gutless from say 3-4.5k rpm - or is this just how the Across is? Any clues? Cheers! Brad

Hey Brad Sounds like a carb holder to me, that link you posted has the instructions on how to check if one has slipped. If it is the slide holder, the plastic part is about $8 from Suzuki, might be a good idea to get 4 replacements. take it easy Chris
Figured I should sign off on this post. I ordered the slider holders ($28 from http://www.suziparts.com.au/ and about $5 postage) Took about 30 minutes to do the job. Remove the pseudo-tank/boot, remove the eight screws holding the carby top covers. One screw didn't want to budge as I reckon these screws had never been undone since they were put in at the factory - and I burred the head slightly - some consolidated concentration and a pair of locking pliers saved the moment (phew). Remove the sliders, slip the slider and holder away from the clips in the rubber diaphragm attached to the upper carby cover. Remove the holders from the inside of the sliders with a pair of needle-nose pliers. Replace with new sliders. Again, the needle-nose pliers come in handy here and the sliders give a definite click when the are properly in position. Put it all back together. Note: I kept track of which slider went into which slider channel just so they went back into the position they had spent the last 27000km in. I don't know if this is important but it made sense to do so. The slider holders weren't as worn as some I've seen in other posts on the web, but they had definitely seen better days... They had a fair bit of scum on them and the sides weren't parallel (note the right hand one in the image above). But with the bike at 27000km I reckon it was worth doing anyway, especially after the crazy outta-control revving situation I'd experienced. Once done, the bike did show a difference in rev 'stability' and also produce more grunt in the 3-4K rev range. Like the bike felt like it should, rather than completely gutless at that rev-range, which, to be honest, was starting to scare me. Nothing worse than needing to gun it out of an intersection and finding you haven't got the herbs. Apart from being dangerous, it's downright embarrassing. Anyways, it's an easy job, hook in. Just be careful with those top screws. As a side note: I think most of my fear when doing bike repairs is that I'll stuff something up and be left without my bike while I wait for some part I've damaged to arrive. It's not like I'm a stranger to tools, grease, WD40 and and afternoon in the shed pulling things apart with a beer in one hand and ratchet in the other - in fact, it's one of the most relaxing pastimes I have!
