Idle knob & rpms

[email protected] #188339 Do all W650s idle higher as they get hotter?? After a few minutes of choke it's around 300rpm but after 20 or 30 minutes it's at 900. Guy who changed my chain and sprocket said he hadn't seen a bike change so much at idle. I guess it's normal because both my current and last w650 did it and I just had my carbs rebuilt.

When cold and after turning off the choke (I dunno, 30 sec or so..maybe a min if it's colder..I listen for the exhaust to make?'crinkle' noises then choke in) it tends to be 600-800rpm. In fact, after choking in and taking off it will sometimes die early if I fail to blurp throttle a?couple times (only because I prefer to ride it cold with no choke. I don't wait 5 min for it to warm up). Anyway, by the time I hit the 1st stop light 4 miles away, it idles perfectly?@ 950 or so. After that it might be right at 1k or a tiny tiny hair above it.? When adjusting the idle, I always do it on a hot running bike, not cold. Which is why for me it's always low when it's cold. toggle quoted message Show quoted text On Tue, Jun 14, 2022 at 1:51 PM drewwils via <drewwils=[email protected]> wrote: Do all W650s idle higher as they get hotter??

Bob Lombardi #188342 I've noticed the same thing.?? If I don't turn the idle knob in to speed up the idle when cold,? it won't even keep running. Then when it's hot after about 10 minutes and the oil has got up to a good temp,? I have to slow it down by backing out the idle knob.?? I try to keep it around 800 rpm when hot. I'm pretty sure Kawasaki knew it had such a varied idle speed and that's why we have such an easy to adjust knob to deal with it. On another note,? when the choke is on,? try to not let it go way up in idle speed.?? I was advised that sitting still without the airflow going over the exhaust pipes is a good way to overheat the chrome and turn it dark near the heads.

Don Leaming All Messages By This Member #188343 You are right, the W650 is very cold blooded. On even a warm morning it likes full choke on start up. It will run a bit rough in a few minutes so you will know it is time to back off the choke and take off. It will warm up to running temperature quicker if under load and then idle at about 8-900 rpm’s.? There should be no need to adjust the idle speed if set up properly.

[email protected] All Messages By This Member #188344 Warmed up idle speed should be around 800rpm.? If it is higher I find it throws off the closed throttle decel fueling.? On mine full choke (actually enriched is a better word in this case) is required for a good ten minutes of riding.? It idles higher when choked.? Once warmed up it settles down to the 800 rpm that I have it set at.? Your idle should be set with a fully warmed up bike and you shouldn't need to adjust it.?? Having a clean idle circuit is a necessity of course and it also helps to be able to adjust the idle mixture screws and I actually have 38 size pilots installed that work better with my W's 2-1 exhaust system.
Don Pat All Messages By This Member #188345 开云体育 Doing anything to the original set up will require tweaking the idle and mixture. Removing all the egr plumbing is a favourite to help eliminating backfire burbles on the decel. Pilot jets are likely in need of help due to ethanol gas.? Beyond that is into ignition modification territory, Kawasaki spent a lot of R&D money on the original setup so two into one exhaust systems, aftermarket carb systems and parts to up the horsepower mean sophisticated bench testing and a dynamometer. My bike is stock except for the egr plumbing and idle tuning. (Not by me! The former owner is a Kawasaki mechanic.)? With 80k on the odometer The bike runs on no ethanol fuel only and give no running issues ever.? Right now if something comes up it likely means the old battery is about done. That is something to look out for with these old second hand bikes when you don’t know the history of the battery. An intermittent ignition failure, or bit of sputtering and power loss can often be traced to an iffy battery. Easy to test with a known good battery.? Many of you know about this site. Lots of good info on our bikes, with over 500 pages now. If you are new to the W650 you might take a look. Don in Niagara

I have just learned to feed a bit of throttle until the bike is thoroughly warm.? On the W, I leave the choke on for about a mile at ~25 MPH, then take it off.? But I keep some throttle whenever I stop in the first 10 minutes or so.? After that, it idles well. Mike E
Jeffrey Alexander All Messages By This Member #188355 this all goes back to the proper starting procedure. W is like an 'old man easing into a bathtub.'? No matter the ambient temp, at the initial start of the day, the W requires sliding the fuel enrichener all the way out. Kick over or thumb the starter. DO NOT REV. the RPMs gradually climb on their own and when they hit no higher than 2krpm, gently slide the enrichener halfway in or so. While the bike continues to warm, just grab your gear and helmet. For the first few miles, the idle won't be smooth because it has not reached full operating temp. so go easy on it, no fast runs, no high revs.?While in motion, I simply slide the enrichener all the way in. For the remainder of the day, you will no longer need the enrichener during any subsequent starts. During off-season, I start it every 2 weeks and gently let it idle. I always top off with a fuel enzyme treatment and use U.S. 93 octane premium. I'm sure it would run just fine on 87 but the previous two owners always ran 93, so I keep it going. I asked Kawasaki themselves about this procedure, which they confirmed. I have had zero issues with this technique. Sales in the U.S. were discontinued years back due to emissions not being met, hence the 'cold blooded' nature of the bike and the small main stock jets and the Kawi clean air system. Also, it did not sell well due to fickle consumer tastes and at the time, people were seeking out this style of bike. It really has been a totally reliable, 'bullet proof' bike and I feel it's perfect, for me :) I know an owner on FB group posted a video of his running with 100,000k? miles! if taken care of and ridden consistently, they will go!
Rev All Messages By This Member #188356 Well folk the reliability of the W650 is confirmed by many riders. My 1999 edition has now completed just over 60,000 miles (96,560k) as we returned recently from a 10day tour of the Northern Spanish Picos from Bilbao to Santiago de Compostela and returning via Santander. The W was the ideal bike for the mountain twisties and was as good as gold carrying my 82 year old frame. A very little enricher in the mornings and off she went followed by 4 other motorbikes of different makes and a 1968 Porsche 911! Keith UK
Sal Emma All Messages By This Member #188357 Yup! What Jseconds said. :)
Don Pat All Messages By This Member #188358 Mr Seconds has provided a very nice roundup of the starting procedure in all weathers. And if at all possible use no ethanol gas or at least the very lowest ethanol blend. Your carbs will thank you for it. Don in Niagara
Peter Wainwright All Messages By This Member #188359 Hi Keith, Great to hear your riding the W at 82 . I,m 72 and hope to match your age, ?kick start mine every time, well almost, as the ?electric start needs a test turnover a couple of times a year.
