I have a problem,that has progressively got more frequent,and worse, over the last couple of weeks,to the point now that i am unable to use the bike at all.
The problem is when the bike is at idle,and then i go to twist the throttle to accelerate,it just chokes & fouls,and the revs actually drop down from the idle 2000rpm till i release,then it's back to idle,then again it chokes downward on the next twist,and through it all,i get no movement at all.
During most of these episodes,with some throttle manipulation and luck,i have managed to get the revs to splutter upwards of the idle mark,and back into life,where it has enabled me to take off and run and perform as normal,but then again at times when i release the throttle to slow right down,and then twist to accelerate,the same problem occurs,and so i'm stopped and having to deal with this problem.
Now even the idling is slightly rough and inconsistant,where as before,that part was o.k.
I have pulled the plug,and found it completely dry black,telling me that it's far to rich. I put a new plug in anyway,and started it,and just listened,to which it then started to idle slightly inconsistant and rough,and the same twist to go,but it just chokes down badly,and no go.
I am going to truck it to my dealer who is 30km's away on Tuesday,where he tells me he's going to put the diagnostic device on it to see if it tells him anything.
Thinking back,i do remember i had some kind of oil leak or spill, about a week before this all started. I noticed my center stand,and behind the transmission casing had blackish oil on them,and a couple of drops on the ground. I checked to see if i could find where it came from but could'nt,and the engine looks clean.
Could it be the air compressor? or the air injector? i don't know, this is beyond me,but that spark plug looks like it's either getting to much fuel,or not enough air.
Perhaps someone knows these symptoms from my descriptions,and can hopefully pinpoint the cause of this problem,so i can take this to my dealer as a back-up,and cross-reference for his analysis.
This is the first time it's ever let me down,and i have a feeling it's got something to do with one of two things that i have changed to my feeding formula just recently,and that is using 98ron fuel instead of 95,and the other is using Agip Cross 2T oil,instead of my trusted Castrol TTS.
One thing for sure,when we find what the problem is,i'll be going back to feeding it my original fuel and oil.
I really miss riding it,and am slighly annoyed,as it's been great weather,but i'm philosophical about it,and just look at the big picture,which always puts things into perspective.
Reply's much appreciated & thanks in advance.
