Westbeef Posted June 13, 2016 Share Posted June 13, 2016 Hello my bikes idle is a bit rough even after a 45 min ride home. I've looked in my Haynes and it suggests to check the ignition system but I've got no electrical testing equipment. I've checked the air filter and that's in good condition (changed about 2 months ago at purchase). I'm going to give it a redex treatment at my next fill up to see if there's any build up in the engine. Is there anything else I can check? I've attached a video of the idle, it's worse near the end. https://vimeo.com/170521181" onclick="window.open(this.href);return false;Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
MR_W Posted June 13, 2016 Share Posted June 13, 2016 Have you checked the oil level at all?Sent from my SM-G935F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 13, 2016 Author Share Posted June 13, 2016 Yes oil was at the upper limit checked that at the same time as the air filter Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Stu Posted June 13, 2016 Share Posted June 13, 2016 could be a slight air leak somewhere idle seems a little high too Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 13, 2016 Author Share Posted June 13, 2016 I tried to look at how to adjust the idle but couldn't find it in the Haynes. Where should I check for air leaks? And do you know how I would adjust the idle/what it should be?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Stu Posted June 13, 2016 Share Posted June 13, 2016 if the bike is fuel injected then the idle is not adjustable on these! an air leak could be around the intake rubbers spray them with wd40 when its running it it almost dies then thats where the leak is also what is the mileage Quote Link to comment Share on other sites More sharing options...
MR_W Posted June 13, 2016 Share Posted June 13, 2016 Checked for a black thumb screw on right side at top of engine? Just below tank as I remember from most bikes.Sent from my SM-G935F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 13, 2016 Author Share Posted June 13, 2016 It's a fuel Injection, so I guess I need to look at some sensors if the air isn't my issues. Is it around the throttle body I need to check?Mileage is 7500Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Stu Posted June 13, 2016 Share Posted June 13, 2016 have you had the valve clearances checked? yeah look around the throttle body if no luck then think about checking the valve clearances dont worry about sensors they will either work or not Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 13, 2016 Author Share Posted June 13, 2016 I haven't was hoping to avoid having it in a garage if possible as I'm skint! Hopefully it's just a seal on the body and they're about 2 quid ( just checked )Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Stu Posted June 13, 2016 Share Posted June 13, 2016 its really easy to check the valve clearances Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 13, 2016 Author Share Posted June 13, 2016 Ah that's good then I'll check the air tomorrow and get the valve clearance done if there's no leaks Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

MYbe you can too? Attached from my workshop manual:- Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 13, 2016 Author Share Posted June 13, 2016 I did some googling and there isn't one on the CBF, I can fiddle with the throttle body to adjust it but that's not s fix just a work around .

Guest Posted June 14, 2016 Share Posted June 14, 2016 That doesn't sound rough. It sounds high. Quote Link to comment Share on other sites More sharing options...
Stu Posted June 14, 2016 Share Posted June 14, 2016 That doesn't sound rough. It sounds high. I think rough idle is the wrong term used Watch the needle it fluctuates Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 14, 2016 Author Share Posted June 14, 2016 Aye maybe not rough but it's not a steady idle. I wasn't aware it was high but having looked now it should be about 1500+/-100 Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 14, 2016 Author Share Posted June 14, 2016 Tried to have a check tonight. New problem, the screws on my fairings are round so I can't get them off!! Fml. Could see in a little bit though and whoever had the bike has left a trail of yellow paint around the bits they've worked on and they've had a look at the throttle body before.

Hoggs Posted June 14, 2016 Share Posted June 14, 2016 Round round or just round? Can you hammer a hex head in? This highly technical tip was bought to you by Hoggs Quote Link to comment Share on other sites More sharing options...
Westbeef Posted June 14, 2016 Author Share Posted June 14, 2016 I had a go at hammering one in but worried about damaging the fairing as its on an unsupported bit. It just bolts two prices of fairing together with nothing behind. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
