Hi All,
Wondering if anyone can help
I bought a 2012 model (black top) about 6 weeks ago and I'm a little stumped by a persistent miss fire on the overrun, rough idle and low speed bogging/ poor pick up, stalling at low revs/road junctions. This was there when I bought it. Give it some beans and it seems fine apart from the overrun single backfire. Have to keep the revs up to stop it stalling which is annoying, distracting and frustrating. If not a little anti social at road junctions!
I have;
1) Changed to a new plug twice. Once to the recommended NGK and second time to the iridium version that some recommend. Absolute bugger to get at in the centre of the cylinder compared to other bikes I've had.
2) Changed the temperature sensor in the back of the barrel for a new one (white connector) that some have also mentioned can be suspect.
3) Checked the valve clearances and they are
Intake left 0.1mm loose 0.15mm tight feeler gauge
Intake right 0.1mm loose 0.15mm tight
Exhaust left 0.2mm okay 0.25 no go
Exhaust right 0.2mm slightly tight feeler gauge
4) Noticed the revs at idle jump around from 1800 to 2500 and can go as low as 1400 and as high as 3500 occasionally.
Looking at the manual the valve clearances seem to be within spec. (0.15mm intake 0.2mm exhaust). Although no range is actually given in the manual just a specific value. The shims are only available in 0.05mm steps so changing them would seem to put the clearances out of spec?
Bike has done 4100 miles.
I'm not a fuel injection expert so not sure what if anything might be wrong to give the above symptoms.
I have noticed that the fan does not seem to come on when riding or when idling the engine stationary. Is this normal? The fan works as I have taken it off and hooked it up to 12V. How long should I need to run it idling for the fan to kick in, I know the weather is cold at the moment,
Also a separate question should the reserve tap on the right hand side of the tank be in the 'off' or 'on' position before getting to need to use the reserve? Will the reserve light come on whatever position it is in? Any harm leaving it in the off position? Nothing mentioned in the manual on where this should be.
It is otherwise a great bike and I'm enjoying my new found freedom (retirement) on the lanes. I appreciate this is a full on highly strung Enduro bike and is designed to be a bit full on/off just wish I could fix this obvious fault.
E-starting on a run out today (every time it stalled) wasn't too bad. I've noticed it likes to be in neutral (takes the clutch drag off the starter) before attempting to start. The run today was more open lanes than one I did a month ago that was more technical (Wye valley) where the e-starter didn't always work. Ending up kicking it a lot (bruises have only just gone
Penalty for softer trials boots
Started out today with a fully charged battery and when I returned it had 12.4V. Right now in the man cave it is 12.2V (it is sub zero outside). Does this sound low? It has the lights hard wired in with no switch to turn them off. I'm fairly sure it is charging otherwise the voltage would be a lot lower at the end if the day with so much e-starting. Could the stator be partially charging? The bogging/poor idle is there even with a fully charged battery at the start if the day.
I know there a few active members (Alwynmike Richgb) that have had this bike in the past just wondered if they or anyone else has any useful advice before I seek 'professional' advice
Many thanks in advance for any good and constructive advice (other than sell it!)
Cheers
Kelvin
